INTRODUCTIONAs supply chains mature, their complexity increases.

Managers are asked to improve productivity whileincreasing customer service. Shareholders expect prof-itability to grow quarter over quarter. These internaland external forces have the effect that often tasks thatpreviously were performed internally become outsour-ced (Williamson, 2008). This results in increasedinteraction among firms in a supply chain andrequires closer relationships to ensure that the flowsof product, information and payments operate effi-ciently (Flynn, Huo, & Zhao, 2010; Frohlich & West-brook, 2001; Thun, 2010; Wagner, 2003). Managingthese relationships requires cross-functional and cross-firm business processes with appropriate levels ofinformation sharing, operational coordination andselect close partnerships (Charvet, 2008; Lambert &Cooper, 2000; Rai, Patnayakuni, & Seth, 2006;Sanders, 2007).

The term “supply chain integration” (SCI) has beendefined as the extent of engagement with suppliersand customers (Frohlich & Westbrook, 2001). Theterms “supply chain collaboration” (Stank, Keller, &Daugherty, 2001) and “supply chain coordination”(Carr, Kaynak, & Muthusamy, 2008) are used todescribe elements of SCI. As “collaboration beginswith customers and extends back through the firm(…), integration is needed both internally andexternally (Stank et al., 2001, p. 29).” In addition,“integration involves coordinating (…) the forwardphysical flow of deliveries” and “the backward coordi-nation of information technology” (Frohlich &Westbrook, 2001). Therefore, it is believed that collab-oration and coordination are elements of SCI(Mackelprang, Robinson, & Webb, 2012).The focus of this research is on SCI. To integrate all

of the studies we collected into one framework, weprovide the following definition of SCI for thisresearch. SCI is the scope and strength of linkages insupply chain processes across firms. Information,operational and relational integration facilitate thelinkages in supply chain processes between firms. The

scope of SCI can be integration with customers, sup-pliers, internal or external. The overall premise of ourresearch is to test whether tighter integration leads tobetter firm performance.A large increase in research investigating SCI has

been observed in the SCM discipline, as shown inFigure 1. Until now, only a few qualitative reviews ofthe SCI literature can be found (Chen, Daugherty, &Landry, 2009b; Fabbe-Costes & Jahre, 2008; Simatup-ang & Sridharan, 2005; Van der Vaart & van Donk,2008). While such studies have a substantial contribu-tion to the field, they do have inherent drawbacksbecause it is challenging to objectively tie together pri-mary research. As the debate between Hanushek(1989, 1994) and Hedges, Laine, and Greenwald(1994a,b) has shown, a subjective review of existingliterature may be just that. In addition, the results of ameta-analysis can be used subsequently to suggestareas in need of further investigation. SCI has oftenbeen operationalized and measured differently, andthis adds to the challenge of integrating the findings.Overall, empirical evidence seems to support the posi-tive impact of SCI on firm performance, howevermixed findings are not uncommon (Flynn et al.,2010). In addition, the selection of firm performance

as the dependent variable is a natural link and hasbeen critical in the literature (Fabbe-Costes & Jahre,2008; Van der Vaart & van Donk, 2008). The moreimportant decision is how to measure and evaluatefirm performance, which is multi-dimensional. It hasbeen show that a single study does not have enoughpower, due to the relatively small sample size, toexplain the magnitude of a statistical relationship(Hunter, 2001; Lipsey & Wilson, 2001). Therefore,aggregating several studies into a meta-analysis is ofcritical importance in order to draw conclusions thatare valid beyond the limited situations in which theywere obtained and make empirical generalizations(Leone & Schulz, 1980).The primary purpose for this study is thus to provide

the first comprehensive, quantitative and integrativereview of empirical research linking SCI to overall firmperformance. The methodological advantage of a meta-analytic study is that statistical artifacts such as sam-pling or measurement error can be accounted for (Hun-ter & Schmidt, 1990). Another advantage is the abilityto examine how various study design factors may affectthe relationship between SCI and firm performance:(1) Is there evidence of a positive correlation betweenSCI and firm performance? (2) Does the correlation

between SCI and firm performance vary across differentdimensions and operationalizations of SCI? and (3)Does the correlation between SCI and firm perfor-mance vary across different performance dimensions?The remainder of the study is organized as follows.

The theoretical background and research hypothesesare developed in the following section. Following thatsection, the research methodology is described andresults of the meta-analysis are reported. Last, conclu-sions are presented, including theoretical implications,managerial implications, limitations and recommen-dations for future research.

THEORETICAL DEVELOPMENTThe process of achieving and maintaining higher

levels of integration is complex and may demandunwarranted resources. To add structure to the rela-tionship of SCI to firm performance, researchers havegrounded their studies in a variety of organizationaltheories. An overview of the most commonly usedtheoretical bases is provided next and highlighted inTable 1. Our primary theoretical focus in this meta-analysis is on the resource-based view (RBV) of thefirm with the extensions of resource-advantage (R-A)theory and the relational view (RV) of the firm. Wealso use secondary but important theoretical lenses,which are described later.

Resource-Based View of the FirmThe RBV posits that firms can be viewed as collec-

tions of resources, some of which can be consideredstrategic resources (Penrose, 1959; Wernerfelt, 1984).Strategic resources are valuable, rare and imperfectlyimitable and substitutable (Barney, 1991). As they aredistributed heterogeneously across firms, they canresult in a sustained competitive advantage (Barney,1991; Peteraf, 1993). Supply chain scholars haveacknowledged that internal/cross-functional and exter-nal integration with customers and suppliers can becomplex and requires unique capabilities that may bedifficult or costly to implement (Barney, 2012; Chen,Daugherty, & Roath, 2009a; Chen et al., 2009b). SCIcan be seen as an internal strategic resource that couldresult in a competitive advantage and improved firmperformance (Barney, 2012).

Resource-Advantage Theory and the RV of the Firm.An extension of RBV, R-A theory, focuses not just onresources per se, but more specifically on advanta-geous resources, which give firms a competitive advan-tage (Hunt & Davis, 2008). Resources under R-Atheory are tied to their contribution in producing amarket offering that has value as perceived by custom-ers and the degree to which they are available areused to create a competitive advantage (Hunt & Davis,2012; Priem & Swink, 2012). Another extension of

the RBV, the RV, postulates that firms can benefitfrom inter-firm integration and strategic partnershipsto acquire valuable resources they lack in-house (Dyer& Singh, 1998). Whereas the RBV focuses on internalstrategic resources, the RV contends that a competitiveadvantage also originates from inter-firm resourcesthat cannot be captured or owned by one firm in iso-lation (Dyer & Singh, 1998; Lavie, 2006; Lorenzoni &Lipparini, 1999). Inter-firm integration can oftenresult in win–win situations where the total supplychain benefits are increased due to the use of hard toimitate specialized assets, skills and information.Mesquita, Anand, and Brush (2008) argue that theRBV and RV can be seen as complementary ratherthan competitive theories. They present empirical evi-dence showing that joint knowledge acquisition, sup-pliers’ investment in dyad-specific assets andcapabilities, and buyer-supplier alliance relational gov-ernance are partnership-specific resources that cannotbe explained by the RBV alone.

Secondary Theoretical LensesIn addition to the primary theories, four secondary

theories were identified among the articles in the sam-ple. With roots in both the RBV and RV, the knowl-edge-based view (KBV; Argote, 1999; Grant, 1996;Kogut & Zander, 1992) states that SCI can help firmscoordinate and deploy knowledge resources byexchanging valuable information across the organiza-tional boundary with key suppliers and customers.Social exchange theory (SET), with origins in sociology(Blau, 1964; Emerson, 1962) and relational marketing(Dwyer, Schur, & Oh, 1987; Morgan & Hunt, 1994),has been used to explain the need for closer interactionbetween organizations, which posits that the basicmotivation for integration is the seeking of rewards andavoidance of punishments (Emerson, 1962). Transac-tion cost economics (TCE) also highlighted some of theintegration benefits (Williamson, 1975). Transactioncosts are the expenses generated by identifying fairmarket prices, negotiating and carrying out economicexchange. With respect to SCI, TCE predicts that firmsshould fare better if they appropriately adjust theirgovernance mechanisms to the underlying transactions(Williamson, 1975, 1991, 2008). The informationprocessing theory (IPT) posits that coping with infor-mation is an organization’s main task and that moreinformation has a positive link with performance(Galbraith, 1973). This, however, is not a constanteffect as an inflection point can be reached at whichmore information does not lead to better performance.

Hypothesis DevelopmentThe theoretical bases provide a lens for examining

the 80 independent samples included in this meta-analysis. Researchers in our sample have used different

definitions, dimensions and operationalizations toexamine SCI (for a more thorough review see: Fabbe-Costes & Jahre, 2008; Van der Vaart & van Donk,2008). While there was divergence among researchers,an aggregate view of SCI is important and is used as astarting point for evidence that SCI indeed has aneffect on firm performance. Generally, a meta-analysis

can be utilized effectively not only to examine narrow,well-defined constructs, but also to assess relation-ships involving more broadly defined constructs(Crook, Ketchen, Combs, & Todd, 2008; Nair, 2006).As mentioned earlier, integration among companieswithin the supply chain can be complex and requiresunique capabilities that may be difficult or costly to

imitate (Barney, 2012; Chen et al., 2009a,b). Beingable to manage these integrative relationships betterthan the firm’s competitors is a valuable internal stra-tegic resource. As such, we predict that SCI enablesmanagement to achieve a sustainable competitiveadvantage which can be viewed by improved firm per-formance (Barney, 2012). Therefore, the first hypothe-sis for this research is the following.

H1: Supply Chain Integration is positively relatedto firm performance.

Dimensions of SCI. After the evaluation of theoverall effect of SCI on firm performance, we have theopportunity to directly evaluate whether diverging con-struct measurement types alter the nature, or magni-tude, of the broader relationship. Researchers made thedistinction between different dimensions of integra-tion. Frohlich and Westbrook (2001, p. 187) explicitlyfocus on the operational aspect in their definition:“The development of shared operational activities withcustomers and/or suppliers.” Flynn et al. (2010, p. 59)define SCI as “the degree to which a manufacturer stra-tegically collaborates with its supply chain partnersand collaboratively manages intra- and inter-organiza-tion processes,” emphasizing the strategic nature ofSCI. Because of such divergent definitions, a morecomprehensive classification of constructs was neces-sary. This classification was developed based on a syn-thesis of the classifications shown in Table 2, with thegoal of succinctly classifying all retained articles.The linkage between integration efforts and firm per-

formance is a central tenant of this research. BecauseSCI requires investment, the objective of managementis to see a return on that investment. All articles inour sample tested this linkage. In line with ourtheoretical lenses, we view SCI as a resource, whichenables the firm to achieve a competitive advantageand thus leads to comparably better performance.After reviewing these diverging, though related, views

and analyzing the vast sample of empirical studies col-lected for the meta-analysis, three dimensions weredeveloped to compare and contrast the specific effectsof SCI on firm performance. This classification encom-passes a wide range of prior conceptualizations which isnecessary in a comprehensive summary of the literature.When management in two firms first engages in SCI,they share data and information (Kim & Lee, 2010; Lee,2000; Olorunniwo, & Li, 2011; Saeed, Malhotra, & Gro-ver, 2005). Thus, (1) information integration refers to thecoordination of information transfer, collaborativecommunication and supporting technology amongfirms in the supply chain. The next dimension in theprogression is when management integrates activities inaddition to the sharing of information (Ireland &Webb, 2007; Kim & Lee, 2010; Kulp, Lee, & Ofek, 2004;

Lee, 2000; Saeed et al., 2005; Van der Vaart & van Donk,2008): (2) Operational integration refers to the collabora-tive joint activity development, work processes andcoordinated decision making among firms in the supplychain. The last dimension builds on the previous twoand goes beyond activities focusing on attitudes (Ire-land & Webb, 2007; Lee, 2000; Saeed et al., 2005; Vander Vaart & van Donk, 2008): (3) Relational integrationrefers to the adoption of a strategic connection betweenfirms in the supply chain characterized by trust, com-mitment and long-term orientation (Chen, Paulraj, &Lado, 2004; Dyer & Hatch, 2006; Hult, Ketchen, & Sla-ter, 2004; Johnson, 1999).

H2a: Information Integration is positively relatedto firm performance.

H2b: Operational Integration is positively relatedto firm performance.

H2c: Relational Integration is positively related tofirm performance.

Dimensions of Firm Performance. As the focus ofthis research, the linkage between SCI and firm perfor-mance is evaluated in more detail. While most empiri-cal studies find a significant positive associationbetween SCI and firm performance, some also revealsignificant negative effects, and the magnitude of theassociation varies considerably. To better understandthis relationship, performance effects collected in themeta-analysis were summarized and evaluated acrossthree categories. Financial firm performance was mea-sured using either revenue minus cost-based measures,such as profitability and return on assets, or purelyrevenue-based measures, like sales and market share.Customer-oriented performance consists of measuresrelated to an improvement in customer satisfaction andcustomer loyalty, or closely related constructs. Finally,operational performance consists of improvements inkey competitive capabilities including cost, quality,delivery, flexibility and innovation (Hill, 1994; Ward,McCreery, Rizman, & Sharma, 1998). Analyses wereconducted both on aggregate firm performance andeach separate dimension. Several studies found a signif-icant relationship between SCI and firm performance.Thus, we hypothesize that SCI is positively correlatedwith different measures of firm performance.

H3a: Supply Chain Integration is positively relatedto business performance.

H3b: Supply Chain Integration is positively relatedto relational performance.

H3c: Supply Chain Integration is positively relatedto operational performance.

Moderator AnalysisOne of the advantages of a meta-analysis is that it

enables the researcher to examine theoretically rele-vant measurement characteristics that may explain thevariability in effect sizes (Hunter & Schmidt, 1990).These moderators enable examination of a moredetailed and specific view of SCI and of firm perfor-mance. The moderators were evaluated by construct-ing specific subgroups that can then be comparedagainst main effects to determine the impact of thatspecific moderator.In addition to the previously described hypotheses,

we examined four scopes of SCI: supplier integration,customer integration, external integration and internalintegration. These were mutually exclusive constructsthat appeared in the sample articles. While someresearchers focused on specific aspects, like customerand supplier integration (Cousins & Menguc, 2006;Homburg & Stock, 2004; Koufteros, Cheng, & Lai,2007), others used more expansive constructs toillustrate the scope of integration efforts (Frohlich &Westbrook, 2001; Thun, 2010). Supplier integration(Chen, Tian, Ellinger, & Daugherty, 2010a; Corsten &Felde, 2004; Flynn et al., 2010; Lee, Kwon, & Severance,2007) moves beyond just buying and selling activitiesand involves close relationships that involve suppliersin activities like product development and manufactur-ing support (Croxton, Garc�ıa-Dastugue, Lambert, &Rogers, 2001). Customer integration (Germain & Iyer,2006; Sanders, 2008) is the mirror image of supplierintegration and it depends on proactively determiningthe requirements of the customer and ensuring to meetthose requirements (Powell, 1995). External integrationis integration with customers and suppliers simulta-neously (Jayaram, Kannan, & Tan, 2004; Stank et al.,2001). While not a core SCI construct for this study,several articles included internal integration into theirresearch models, some see internal integration betweenthe four walls of the company as an implicit compo-nent of SCI (Flynn et al., 2010; Rosenzweig, Roth, &Dean, 2003), while others operationalize it as an ante-cedent or complement to external integration (Nara-simhan, Swink, & Viswanathan, 2010; Sanders, 2007).We refer to it as the integration between functions ordepartments within a single firm (Braunscheidel & Sur-esh, 2009; Closs & Savitskie, 2003; Koufteros, Rawski,& Rupak, 2010).There were also several types of firm performance

that were examined individually. Within business per-formance, we specifically examined financial perfor-mance and customer-oriented performance. Financialperformance is an important measure of firm perfor-mance and has been used in several studies withinour sample (Germain, Davis-Sramek, Lonial, & Raju,2011; Vickery, Jayaram, Droge, & Calantone, 2003).Customer-oriented performance is a more perception-

based measure that includes attitudes like satisfactionand loyalty (Johnston, McCutcheon, Stuart, & Ker-wood, 2004; Narasimhan, Jayaram, & Carter, 2001).Within operational performance, there were enoughstudies to evaluate the specific effects of cost, quality,delivery, innovation and flexibility. The importance ofevaluating these relationships is to enable us to gain adeeper understanding of where exactly the perfor-mance benefits from better SCI arise. The conceptualframework for this research is depicted in Figure 2.

METHODOLOGYIn this section, we first describe sample selection.

Next, the coding of the studies is explained. Then, wedetail the meta-analytic procedures that were used totest the hypotheses.

Sample SelectionTo test our research model, we gathered correlations

between relevant constructs and followed the randomcoefficient meta-analysis approach suggested by Hunterand Schmidt (2004). Relevant articles for the meta-analysis were identified via a literature search using theEBSCO Business Source Complete database includingappropriate keywords. An overview of the search termsand search results is shown in Table 3. The search wasrestricted to academic peer-reviewed journals, and itwas ensured that the search results were indeedresearch articles and not editorials or book reviews. Noother limitations were placed on the search. This pro-cedure yielded 552 articles that were further inspected.Individual items of the constructs were assessed toensure that the authors used measures of the constructsof interest that had face validity and that inter-con-struct zero-order correlations were obtainable. To beconsidered usable, the articles had to employ anempirical research methodology and include at leastone measure of SCI and one measure of firm perfor-mance, as shown in Table 3. Forty-eight articles wereretained. In addition to the keyword search, a “snow-balling” approach was also used to retrieve additionalstudies and it required us to inspect articles that werecited by our retained articles or that cited our retainedarticles. This procedure yielded another 38 usable arti-cles. In total, 86 articles using 80 independent samples(k) and representing 17,467 observations (N) were suc-cessfully identified, coded and used for further analy-sis. They are shown in Appendix A.

CodingA formal coding framework, based on the theoretical

framework and potential moderators, was establishedand employed independently by two of the authors.All articles were double-coded and any discrepancieswere resolved via discussion. The inspection of articles

required a thorough assessment of the scale items toidentify several characteristics of the scale: (1) we deter-mined whether the scale was consistent with any ofour definitions of SCI; (2) we assessed whether theconstruct was consistent with any of the SCI dimen-sions in Figure 2; (3) we examined whether the con-struct was consistent with any of types of firmperformance; and (4) we identified whether there wereany moderators (Figure 2). To ensure that the items ofeach construct should reflect the respective subgroup,75% of the items should closely match our definitionfor that construct (Hunter & Schmidt, 2004). Each arti-cle was evaluated in the above manner, and weobtained correlations and reliabilities for all constructsof interest. The independent coding exposed fourteen

differences, yielding an inter–rater reliability of95.93 percent (14 differences/(86 studies * 4 codingsper study)). Multiple publications based on the samesample were treated as a single sample to maintain theassumption of independence among correlations(Hunter & Schmidt, 2004). In the case of multiple cor-relations for one relationship, the composite of thecorrelation coefficients was computed using aggrega-tion methods described in the meta-analytic proce-dures section. If zero-order inter-construct correlationsor reliabilities were not reported in the article, we solic-ited the required information via e-mail. If we werenot successful, the tracing rule was used to reproducethe correlations of interest (Kenny, 1979). In the casethat only item-level correlations were reported, a

confirmatory factor analysis was used to derive theinter-construct correlations (Droge, Jayaram, & Vickery,2004). Each article was evaluated and the constructswere classified into a-priori categories (Figure 2), whichwere then used to test the hypotheses, by splitting thestudies into different sub-groups depending on theoperationalization of the constructs and the use of thepreviously mentioned moderators.

Meta-Analytic ProceduresThe widely employed meta-analytic procedures

described by Hunter and Schmidt (1990, 2004) werefollowed for the hypothesis testing via three stages:(1) the main effect testing; (2) the moderator exis-tence testing; and (3) the moderating effects testing.In the first stage, the overall relationship correlationbetween SCI and firm performance was assessed. Thecorrelation (r) was used to assess the relationshipsbetween the constructs of interest (see Geyskens,Krishnan, Steenkamp, & Cunha, 2009; and Shadish &Haddock, 1994 for discussion on different effectsizes). Corrections were applied for measurementerror (Hedges & Olkin, 1985; Hunter & Schmidt,2004; Rosenthal, 1991). If no scale reliability wasreported or if a single-item scale was used, the com-mon practice of substituting the mean reliability wasfollowed (Chen, Damanpour, & Reilly, 2010b; Crooket al., 2008; Mackelprang & Nair, 2010; Nair 2006).Each sample was weighed by its compound attenua-tion factor, which consists of the reliability of thescale and the sample size. Several articles had morethan one correlation of interest and those were com-bined into a composite (Arthur, Bennett, & Huffcutt,2001) following Hunter and Schmidt (1990, pp. 457–460). Publication bias, also referred to as the “filedrawer problem,” may occur because studies that pro-duce statistically nonsignificant findings are less likelyto be submitted to journals or be accepted for publi-cation (Rosenthal, 1979). Therefore, the “fail safenumber” was assessed for each group and sub-group,which indicates how many additional studies wouldhave to be found to obtain a nonsignificant result(Rosenberg, 2005).

RESULTSTo test our study’s hypotheses, the correlation

between our constructs of interest was evaluated. Theresults are shown in Tables 4 and 5. To determine thestrength and significance of the relationship, severalmeasures were calculated. For each relationship, thenumber of independent samples (k) and the overallsample size (N) are provided. The observed correla-tion (ro) and the corrected correlation (rc) were com-puted (Hunter & Schmidt, 2004). These measuresprovide a point estimate of the sample correlation

that is then assessed as to whether it is significantlydifferent from zero. The range of uncorrected correla-tions and the 90% credibility interval are alsoreported (Hunter & Schmidt, 2004, p. 83). The Q Sta-tistic is a measure of heterogeneity and a large signifi-cant value points to unexplained variance beingpresent in the sample or subsample (Hunter &Schmidt, 1990, p. 111). The fail safe numbers foreach subgroup range from 107 to 61,995, and thus,we conclude there is little risk of additional studieschanging the results we obtained.The relationships between SCI and firm performance

were evaluated, and the results provide evidence thatthe link is positive and significant (Table 4). To exam-ine the more specific types of firm performance, anoverall view of SCI is necessary, and thus, we exam-ined the aggregate effect of SCI on overall firm perfor-mance first. The other relationships can then becompared subsequently. The corrected correlationbetween SCI and firm performance was 0.36, which issignificant at the 0.05 level, and thus, we concludethere is support for H1. In addition to the maineffects testing, several moderators, based on the opera-tionalization of the SCI construct, were tested and areshown in Table 3. Three types of integration wereevaluated specifically: information (H2a), operational(H2b) and relational (H2c). While information inte-gration and relational integration show significantcorrelation with firm performance, operational inte-gration does not have a significant correlation withfirm performance. Drawing on the RBV, it can beargued that these types of integration are moredifficult to imitate and as such can lead to better firmperformance. The nominal correlation does not differwidely from the others, but the variance and the cred-ibility interval explain why it cannot be concludedthat it is significantly different from zero. Fouradditional scopes of SCI were evaluated: supplier,customer, external and internal integration. There isweak support for a significant correlation betweensupplier integration because the corrected correlationhas a larger standard deviation that prevents us fromconcluding it is larger than zero. There is no supportto conclude that a significant correlation between cus-tomer integration and firm performance exists in thissample. External and internal integration show a posi-tive and significant correlation with firm performance.In addition to the different operationalizations of

SCI, we also evaluated whether the correlationbetween SCI and firm performance is impacted bymeasurement differences in the dependent variables.The results are shown in Table 5. We found weak sup-port for H3a, but strong support for H3b and H3c.While business performance, which is conceptualizedas the top line benefits of SCI, has weak support,additional subgroups were evaluated, such as financial

performance and customer-oriented performance. Thecorrelation between SCI and financial performancewas not significant. The evaluation of the linkbetween SCI and customer-oriented performance washighly significant and did not show any heterogeneity,so that we can conclude that there is no evidence forsignificant moderators being present in the sample.This was the only subgroup where it was possible toresolve all the heterogeneity. Additional subgroups ofoperational performance were evaluated: cost, quality,delivery, innovation and flexibility. The relationshipsbetween SCI and quality, delivery, and innovationwere significant. No significant relationship betweenSCI and cost and SCI and flexibility could be found.The implications of these results are described in thenext section in addition to limitations and suggestionsfor future research.

CONCLUSIONSIn this study, we accumulated and integrated the

results of empirical research on the relationshipbetween SCI and firm performance that may lead togeneralizable evidence for advancement of theory andpractice on SCI. Inconsistencies in original research

results may be due to artifacts such as sample sizesand measurement errors in the original studies. Sub-group analysis of moderators showed that the major-ity of samples have a significant relationship betweendifferent operationalizations of SCI and operational-izations of firm performance along theoretical expecta-tions. A necessary implication of this meta-analysis forfuture research is that when results are contradictingor nonsignificant, it may be due to the study’s hetero-geneous factors, for example, the industry, the type ofcompanies that were considered, or even the time per-iod in which the research was conducted. In that case,a detailed assessment of significant differences in cor-relation coefficients for various subgroups may explaindeviating results.

Implications for TheoryIn initiating this study, we encountered an expansive

literature base that appeared to use an array of per-spectives and different theories in investigating SCI.We examine SCI under the lens of the RBV of the firmand the extensions of the RBV that were R-A theoryand the RV. Our primary objective for this meta-analysis was to investigate whether SCI as a firmresource is related to better firm overall performance.

This can help determine whether SCI should beviewed as a source of competitive advantage. In thisarticle, we have presented a theoretical framework toaid in providing parsimony and to distinguishbetween three dimensions of SCI (information, opera-tional and relational). Our classification of SCI can beused to interpret past research on SCI and clarifies theconcept for future research. Setting a baseline via thismeta-analysis synthesizes existing knowledge and aidsscholars in scoping new research.The overall positive and significant relationship

between SCI and firm performance (H1) is a signifi-cant, but not surprising result (Christopher, 2005).Closer integration is significantly correlated with bet-ter firm performance. This finding fits with the theo-retical bases that we highlighted in this research.While this result does not specifically point to causal-ity, it should be expected that firms engaging in inte-gration efforts should experience higher firmperformance as a result. It is also apparent that thisgeneral relationship is characterized by considerableheterogeneity (Q = 526.02**), which was thenreduced in subsequent subgroups.Prior research provides support for the notion that

firms have the opportunity to leverage integrationmechanisms with customers and suppliers to achieve

organizational performance benefits (Cooper, Lambert& Pagh, 1997; Lambert, Cooper, & Pagh, 1998; Ste-vens, 1989; Lee, 2000). At the same time, researchershave noted that firms working toward higher levels ofSCI are likely to face a number of challenges (Fabbe-Costes & Jahre, 2007; Fawcett & Magnan, 2002). Inthe next step, three separate operationalizations of SCIwere analyzed. Information integration is significantlycorrelated with firm performance (H2a). This resultcan be explained by arguing that sharing of informa-tion will enable both companies to operate moreefficiently (Zhou & Benton, 2007). It can also beexplained with IPT, where better information for theright parts of a firm can lead to a competitive advan-tage. In addition, internal integration also has a signif-icant correlation with firm performance. These twotypes of integration are generally considered as requir-ing the least involvement and effort.For the relationship between operational integra-

tion and firm performance, we did not find a signifi-cant correlation (H2b). A higher level of integrationlikely causes temporarily higher costs, and it is possi-ble that the resulting increase in performance is notlarge enough to recoup those higher costs. Firmsthat were surveyed in the original studies may alsonot have been able to yet recognize the positive

results of operational integration, as these benefitsmay take longer to realize. It is not possible toobtain a firm-specific perspective with our research,but we find it likely that the risk of failure at thisstage of SCI is significant and therefore the resultswe obtain have such a large variance. This interpreta-tion is additionally supported by the two modera-tors, supplier integration and customer integration,having a nonsignificant correlation with firm perfor-mance. This is not to say that an improvement infirm performance does not occur, but our resultsseem to indicate that the variance, and therefore theassociated risk, is higher regarding the return oninvestment.Relational integration, which mainly draws on the

RV as its theoretical base (Dyer & Singh, 1998), doeshave a significant correlation with firm performance(H2c). It is understood that only firms that have along-term relationship will be able to attain such alevel of integration. Therefore, it is not surprising thatthe payoff from closer integration is higher and thereis less risk involved with that type of integration. It isalso reasonable to assume that firms that are seekingthis level of integration do have more experience withintegration efforts and the chance for success isincreased even more. As such we believe that it shouldnot be uniformly assumed that tighter integration isbetter in all situations. It comes with a higher level ofmanagement effort, and there must be a business rea-son for investing resources into the relationship. Thisview is supported by Lambert, Emmelhainz, andGardner (1996) who present a model that describeshow firm relationships should be structured at theappropriate level. Both companies should take intoaccount the drivers, facilitators and managementresources available for managing the relationship.The evaluation of different measures of firm perfor-

mance revealed several noteworthy findings. Theimpact of SCI on business performance, which is gen-erally associated with revenue generation and profit-ability, is not significant (H3a). The weak link torevenue generation and the bottom line is not surpris-ing because most of the benefits from SCI are expectedto be in the form of cost savings (Madhok, & Tallman,1998). Such efficiencies often do not have the profit-ability impact to warrant a significant change in thebottom line as the savings do not have the same profitleverage as revenue increases (Marn & Rosiello, 1992).More specifically, financial performance also had anonsignificant effect, which is additional evidence. Theimpact of SCI on customer-oriented performance,which specifically is related to relational outcomessuch as satisfaction, trust and commitment, has a highand significant correlation. This result points to thefact that closer integration with customers and to a les-ser extent with suppliers can have intangible benefits

that can improve the relationship. These benefits maynot be immediately measurable in financial or busi-ness terms, but marketing researchers argue that laggedfinancial benefits occur as a result of customer-orientedperformance (Guo, Kumar, & Jiraporn, 2004).A few studies used relational performance as an out-

come measure, and the correlation was the highest weobtained in this study (H3b). Most of the studies(four of six) used relational SCI as the antecedent.While this result is impressive, we must also cautionthat we cannot exclude cognitive bias as one of theexplanations for this result. It would be more impres-sive if such high correlations would be obtained withfinancially based performance measures. We generallyadvise researchers against the use of fully perceptualmeasures because this often overlooked concern ofcognitive bias can inflate the relationship.Most studies (k = 60) in our sample used opera-

tional performance as one of the outcome variablesand a positive and significant aggregate correlationwas found (H3c). While this aggregate view of perfor-mance is important, the specific subgroups of opera-tional performance should be evaluated further. Withthree of five subgroups not having significant correla-tions, several conclusions can be drawn. Costimprovements are a not significant outcome of SCI,and this result, while surprising to some, highlightsthe fact that substantial resource commitment is nec-essary when undertaking integrative activities betweencustomers and suppliers. The impact of SCI on qualitywas also not significant, and we attribute this to qual-ity being an imprecise measure that can be interpretedin several ways. As such, it may not be possible toaccurately trace the improvements to quality gains. Inaddition, quality is always a moving target, and theoverall customer perception of quality will be influ-enced by the competitors in the marketplace. The cor-relation between SCI and delivery performance waspositive and significant. One of the main areas wherefirms integrate is how products are delivered, thus it isnot surprising that delivery performance is signifi-cantly affected by SCI. Another significant effect is thelink between SCI and innovation. We draw on SET toexplain that managers from customers and suppliersworking together might create opportunities for inno-vation, purely based on the fact that they are interact-ing with each other. Therefore, SCI has the effect thatpeople from different companies can likely encounteropportunities for improvement in their daily interac-tions as part of a larger integration initiative. The lastsubgroup that was evaluated was the impact of SCIon flexibility, and we attribute this result to the factthat different companies may have different con-straints (Christopher & Holweg, 2011). While the con-straints become clearer through integration, it maynot be possible to overcome them.

Implications for ManagersA meta-analysis, such as the one described in this arti-

cle, can help managers understand the level and signifi-cance of the relationship between SCI and firmperformance. More specifically, this study can helpanswer questions such as what type of SCI has thechance to lead to the highest benefits in terms of firmperformance. There is evidence that SCI leads to higherfirm performance, in general; however, more impor-tantly managers should understand what will be mostbeneficial to their organization. On the basis of ourresults, all levels of integration can be beneficial forfirm performance; however, operational integrationcan have varying results. The operational benefits ofSCI are only found in the areas of delivery performanceand innovation. This result provides support to thenotion that managers should not expect quick payoffsfrom their integration initiatives, like cost savings andquality improvement, but it is more likely that longerterm, more durable performance gains can beobtained.

Limitations of the ResearchAs with any research, there are several limitations

that must be pointed out. By definition, a meta-analy-sis relies on available studies. While we performed athorough literature search and “snowballing” to iden-tify all suitable articles, there still is the possibility thatsome studies were missed. However, due to the num-ber of samples that we were able to obtain (80 inde-pendent samples) and the high fail-safe numbers(Tables 4 and 5), we are confident that any additionalstudies would be unlikely to change the results. Whileevery effort was made to obtain all the informationnecessary for each suitable study, we did encountersome difficulties in retrieving correlations and reliabil-ities for some studies. If that information was notavailable from the authors and we could not imputeit otherwise, we had to drop those studies from thismeta-analysis. We were able to obtain a significantlylarger number of samples than some other recentlypublished articles using this methodology (Mackelp-rang & Nair, 2010; Nair, 2006). However, due torestrictions in the sample, we were not able to exam-ine more sample-specific moderators.

Suggestions for Future ResearchIt is of critical importance for our discipline to

assess a phenomenon over an extended period oftime. Once there are sufficient empirical studies, ameta-analysis can be performed to aggregate theresults. This methodology should be employed tostudy other phenomena in the supply chain manage-ment domain. It would be interesting to see how SCIis viewed over an extended period of time. While such

longitudinal studies are difficult to operationalize,they would add significantly to our understanding ofthis important phenomenon.Due to the small sample size of the SCI customer-ori-

ented subgroup, it is clear that additional studies arenecessary in this area. The nonsignificant correlationsbetween SCI and cost performance, and SCI and qual-ity performance might be be due to the focus of opera-tional-level management primarily on delivery issues.As such, we suspect that in the future we may find dif-ferent results and as such it is worth investigating thiseffect more.At this point, we would like to encourage authors,

referees and editors to agree to a consistent standard ofreporting for empirical survey-based research, whichcan only improve methodological rigor. At a mini-mum, the correlations between the latent variables andthe reliabilities of the constructs should be reported. Inaddition, detailed information on how the scales weredeveloped should be required to trace the origin of ascale and to enable other researchers in the field toassess the quality of the constructs. Such a standardwould not just make it easier to aggregate studies in ameta-analysis, but also enable readers to evaluate stud-ies more quickly and objectively. As we have seen insome of the studies we evaluated, some constructs thatwere based on previously developed measures weremodified without explanation. Therefore, we call onour colleagues to adhere to this standard in order toincrease the methodological rigor of our field.Supply chain integration has been a highly

researched topic in the past 20 years. In this meta-analysis, we examined this significant body of litera-ture to quantitatively summarize the results. The mainbenefit of our analysis is that we were able to estimatethe overall population effect of SCI on firm perfor-mance and within the relevant subgroups. The posi-tive association reinforces the importance of thisconstruct, but the significant amount of heterogeneityin most subgroups is evidence that additional researchis necessary before we can make generalizable state-ments. As such we call for more research on the rela-tionship between SCI and firm performance.
