AbstrAct

Enterprise resource planning (ERP) systems have been widely implemented by numerous firms throughout the industrial world. While success stories of ERP implementation abound due to its potential in resolv-ing the problem of fragmented information, a substantial number of these implementations fail to meet the goals of the organization. Some are abandoned altogether and others contribute to the failure of an organization. This article seeks to identify the critical factors of ERP implementation and uses statisti-cal analysis to further delineate the patterns of adoption of the various concepts. A cross-sectional mail survey was mailed to business executives who have experience in the implementation of ERP systems. The results of this study provide empirical evidence that the theoretical constructs of ERP implementation are followed at varying levels. It offers some fresh insights into the current practice of ERP implementation. In addition, this study fills the need for ERP implementation constructs that can be utilized for further study of this important topic.

IntroductIonEnterprise resource planning (ERP) systems are widely implemented as the backbone of many manufacturing and service firms. They are designed to address the problem of information fragmentation or “islands of information” in business organizations (Muscatello, Small, & Chen, 2003). A typical ERP system integrates all of a company’s functions by allowing the modules to share and transfer information freely (Hicks & Stecke, 1995; Chen, 2001). In addition, all information is centralized in a single relational

database accessible by all modules, eliminating the need for multiple entries of the same data. Customers and suppliers with network security clearance are allowed to access certain types of information by way of an external communica-tion interface.

ERP systems offer tremendous opportuni-ties to more consistently provide information to organizations in a standardized, centralized, and cost efficient manner (Olson, Chae, & Sheu, 2005). Many industry reports extol the virtues of ERP and its multiple benefits for those firms that

can successfully implement these systems. One of the primary objectives for installing ERP is the ability to integrate business processes (Brakely, 1999; Davenport, 1998, 2000). ERP has also been found to be effective in reducing inven-tory costs, improving efficiency, and increasing profitability (Appleton, 1997; Brakely, 1999). In addition, ERP has been credited with reducing manufacturing lead times (Goodpasture, 1995; Davenport & Brooks, 2004). Other potential benefits of ERP include drastic declines in inven-tory, breakthrough reductions in working capital, abundant information about customer wants and needs, and the ability to view and manage the extended enterprise of suppliers, alliances, and customers as an integrated whole (Muscatello, Small, & Chen, 2003). Clearly, the integrated information technology of ERP software has the potential to provide manufacturing firms with extensive new competitive capabilities, especially since the real-time information can improve the speed and precision of enterprise response. Given the widespread popularity of ERP software, and the spectacular successes achieved by a few firms, an open question remains: Why has the effective deployment of ERP systems proven to be elusive for the majority of firms (Stratman & Roth, 2002)?

Implementation of an ERP does not come without significant technical and managerial challenges, huge financial investments, and a great deal of organizational change. Opera-tional problems at Hershey Foods, Whirlpool, FoxMeyer Drugs, and more recently Hewlett Packard, have been blamed on poor implemen-tations of ERP solutions (Becerra-Ferandez et al., 2005). ERP also has the reputation of be-ing notoriously over-sold and under-delivered (Millman, 2004). Cliffe (1999) even reported that 65% of executives believed that ERP could be harmful to their organizations.

Researchers have attempted to identify the set of factors that are critical for ensuring success with ERP implementations. Most of these authors, however, have developed their list of critical success factors from a small number of case studies. For example, Holland and Light (1999) and Motwani, Mirchandani,

Madan, and Gunasekaran (2002) offered a list of critical factors using two case studies. More recently, Kumar, Maheshwari and Kumar (2003) identified several success factors based on data collected from 20 Canadian firms. Employing a large scale survey, this article seeks to ascertain how businesses receive these concepts and, more specifically, which concepts are practiced widely and which are not. With this goal in mind, perti-nent constructs of ERP implementations based on a critical review of business and managerial literature are first identified and developed in the second section. The research design, including data collection is then explained in the third section. The fourth section presents the results along with implications of the study findings. In the concluding section, the limitations of the study are highlighted along with guidelines for future research.

thEorEtIcAl constructsThis section identifies key factors of ERP implementations based on a critical review of both scholarly and managerial literature. These constructs include strategic initiatives, executive commitment, human resources, project management, information technology, business process, training, project support and communications, and software selection and support. The constructs developed by the authors are very similar to the ones developed by Stratman and Roth (2002), further validating the research effort undertaken here.

strategic InitiativesSuccessful integration of the internal functions of the business does not necessarily guarantee business success. End-to-end processes that transfer information from module to module will not in themselves improve cost effectiveness and efficiency. The ability to use the information to drive the business is the key to successful integration. Performance measurements must be developed to measure the impact of the ERP system on the business. It has been suggested that an ERP system that is not strategically tied into the supply chain will lack the ability to provide the type of business intelligence

that is needed to grow the business (Hickes & Stecke, 1995; Koch, 1999; Carr, 1999; Melnyk & Stewart, 2002; Davenport & Brooks, 2004). Therefore, it is essential that firms must have strategic goals in place before undertaking an ERP implementation (Motwani et al., 2002).

Executive commitmentTop management is often advised to look be-yond the technical aspects of the project to the organizational requirements for a successful implementation. It is consistently identified as the most important success factor in ERP system implementations (Bancroft, Seip, & Sprengel, 1998; Davenport 1998; Sumner, 1999; Bingi, Sharma, & Godla, 1999; Welti, 1999; Gupta, 2000; Rao, 2000). It can be inferred from the literature that executives and managers believe that ERP systems help their company achieve greater business benefits. However, they are mystified as to how to design, implement, and manage an ERP project. When it comes to ERP projects, Fortune 500 companies are beginning to sound like children in the back seat of a car on a long drive—“Are we there yet? Are we done yet? No! We’re not there and we are not done. And we may never be done” (Koch, 1999).

Any executive planning the implementation of an ERP system needs to make some savvy decisions, from identifying what business needs the ERP system must meet to preparing for post-implementation maintenance and user support (Musson, 1998). Many executives are having a hard time understanding that ERP implementation is not simply a package installation. It is a long journey of fine-tuning, upgrading, and continual learning, not a sprint. Therefore, it may lead to a sense of frustration and anger at the system and in some cases total abandonment. Unlike any other software project, an ERP system does not merely change employees’ computer screens the way previous generations of software did; it changes the way they do their jobs and how the company does business. Top management, therefore, must fully understand the degree of the changes and supports needed for the new project and be comfortable with the fact that the decisions their planners make will have a

profound impact on the entire supply chain (Chen, 2001).

human resourcesThe most recurring theme in management litera-ture concerning the failure of ERP systems is the inability of firms to take into account the new organizational, interdepartmental, and person-nel aspects of work organizations. Unintended consequences include the emotional fallout when employees are suddenly given much greater responsibilities. Managers sometimes neglect to assess not only the skill development needed by employees but also the organizational changes required of them (Appleton, 1997). Small firms often lack financial resources and may be forced to adopt, at best, a piecemeal approach to integrating the typically expensive ERP systems into their facilities (Ferman, 1999). This can be very difficult for employees as the project seems to be ‘never ending.’ It is also felt that the low information technology (IT) staff levels in smaller enterprises are inadequate for the rigorous and extensive IT training and development requirements of an ERP project (Hill, 1997). In many cases of ERP implementa-tions, consultants are required to help meet the projects’ needs (Muscatello et al., 2003).

Project ManagementA project team must be flexible and deal with the problems as they arise in the implementation process. Anyone who revisits the charter docu-ments of a large-scale ERP project will see that the ultimate product is almost always shaped by unanticipated and late breaking circumstances. It is a fact of business life that important things come up later rather than earlier in complex new projects (Cliffe, 1999). However, these inter-ruptions should not encourage “scope creep,” when processes or functions are added after the project has begun. As mentioned, unanticipated circumstances are the norm; however, wholesale changes such as adding an additional process, module, or department after the project has been scoped and started may lead to a “never ending” project. To prevent scope problems, firms need to make sure a project charter or

mission statement exists. It is paramount to nail down the project requirements and have them documented and signed by the senior management and users. Furthermore, it is es-sential for firms to clearly define change control procedures and hold everyone to them. Tight change control procedures may end up causing tension between the project team and those who do not get the changes they want. Ultimately, though, the project will not be successful if the project team is trying to hit a constantly moving target (Trepper, 1999).

A survey by the Meta Group found that it takes an average of 31 months before an ERP system will show benefits (Muscatello, 1999). There is no magic in implementing ERP systems, but, when they are carefully conceived and executed, ERP systems can radically changed the way companies do business. In many com-panies, it would now be unthinkable to manage financials, customer relationships, and supply chains without ERP (Oliver, 1999).

Information technologyDeloitte Consulting (2000) reports that the second largest ERP implementation challenge related to people issues is internal staff adequacy. If a firm’s existing technology will run the new ERP system, then the technology training may be an upgrade of the skill set. If a wholesale change is required, such as moving from an IBM mainframe to a Sun Microsystem, then an in-depth hardware and software training program must be implemented. In fact, some firms have selected their ERP systems based on their current technology and business process, and research has showed this approach to be a mistake since it is very limiting (Anderson, 2000). Because some firms may not be will-ing to change current technology, they may consequently report a lower significance on technology training for ERP implementation. Firms who account for business processes first and technology fit second reflect IT training positively (Davenport, 2000).

Managers cannot minimize the importance of technology training regardless if it is an upgrade of current software and hardware or

a complete technology change. An upgrade of current software usually includes new file struc-tures, report writers, functional modules, and other changes. An upgrade of current hardware usually involves a re-installation of the operat-ing system or at least installing the operating system changes, new functionality, and new modules. If a complete technology change (hardware and/or software) is required, then a much larger commitment must be undertaken to insure that the proper employees can man-age the technology after going live. In either case, managers must be proactive in securing the technology training to insure that their technical employees can run the ERP system effectively. The consequences of not having enough technical training can be catastrophic and lead to outright failure of the ERP system (Evangelista, 1998; Hill, 1997).

business ProcessAs suggested by Hammer and Champy (1993), reengineering of business process activities focuses the firm on identifying and improving the efficiency of critical operations, on restruc-turing important non-value-adding operations, and on eliminating inefficient processes. Reen-gineering should be undertaken to insure that the strategic objectives mentioned earlier are feasible. The reengineering effort should create a uniform response from all aspects of the busi-ness. When goals are common, improvement becomes a shared task (Hill, 2000). Using reen-gineering techniques to develop a homogeneous vision depicting the company’s processes after the ERP implementation, a firm is more likely to minimize uncertainty and achieve success. Researchers have found a strong correlation between the attention paid to business process improvement and the likelihood of ERP suc-cess (Muscatello et al., 2003; Motwani et al., 2002; Carton & Adams 2003; Millman, 2004; Olson et al., 2005).

trainingERP skills have been in acute shortage because of the high demand for people with good un-derstanding of business and ERP systems. This

and the radical process changes brought about by ERP implementation have made providing sufficient and timely training to project per-sons and users a critical requirement in ERP implementation (Davenport, 2000). Assessing the needs for training usually uncovers several training and skills deficiencies. Rectification of training deficiencies can be accomplished in three ways: reassignment, outsourcing or replacement of staff, hiring of new personnel with substantial knowledge in ERP systems, or training of managers and key employees. In most cases, a firm implementing ERP engages in two types of training: fundamental ERP systems education and technical training in the usage of the ERP software (Evangelista, 1998; Muscatello, 2002; Yusuf, 2004; Sarkis & Sundarraj, 2003). In international cases, language and cultural barriers can be a techni-cal hindrance that requires additional training (Al-Mashari, 2000).

Project support and communicationsERP applications lock the operating principles and processes of the adopting organization into software systems. If organizations fail to reconcile the technological imperatives of the enterprise systems with their business needs, the logic of the system may conflict with the logic of business processes (Davenport, 1998). Needless to say, managers have found ERP implementation projects the most difficult sys-tems development projects (Kumar et al., 2003). Thus, upfront and ongoing communication to all employees affected by the new ERP system is a must. Olsen et al. (2005) found that it is necessary to inform organizational employees of how the system can help them do their jobs better. They also found that all retained em-ployees are going to find their jobs changed. People are naturally resistant to change and it is very difficult to implement a system within an organization without some cooperation. Effective communication and ongoing support has also been noted by several researchers (e.g., Motwani et al., 2002; Muscatello et al., 2003; Sarkis & Sundarraj, 2003).

software selection and supportERP systems are software packages generically designed, keeping the industry-wide needs and best practices in mind (Kumar et al., 2003). One of the major challenges an adopting or-ganization faces is that software does not fit all their requirements (Davenport, 1998). A systematic “needs assessment” therefore must be commissioned to determine the specific ERP modules, subsystems, and hardware that are required to achieve the desired level of systems integration. Where there is a lack of internal knowledge of ERP systems and their operating requirements (either at the corporate or division level), management should solicit the help of knowledgeable outside consultants for the assessment (Chen, 2001; Davenport, 2000; Booker, 1999). Firms that analyze their software “fit” and individual module needs can enhance the likelihood of a successful ERP implementation (Yusuf, Gunasekaran, & Althorpe, 2004).

Data CollectionBased on a thorough review of the literature,

the theoretical constructs identified by this study are well grounded in existing theory (Muscatello et al., 2003). The theoretical constructs are made up of four or more items using a 7 point Likert scale with a score of 1 labeled “not important” and a score of 7 labeled “very important.”

A cross sectional mail survey was con-ducted in the United States, during 2006, draw-ing from members of the American Production and Inventory Control Society (APICS), The National Association of Accountants (NAA), the American Productivity and Quality Center (APQC), and the Institute for Supply Manage-ment (ISM) because of their potential involve-ment in an ERP implementation. The survey was very clear that only those with ERP implementa-tion experience should respond.

A modified version of Dillman’s total de-sign method was followed in order to increase the response rate (Dillman, 1978). All mailings were first class mail including a cover letter,

survey, and postage paid return envelope. Three weeks after the initial mailing, reminder cards were sent to all potential respondents. Of the 973 surveys mailed, 28 came back due to address discrepancies. From the new sample size of 945, 203 were received resulting in a response rate of 21.5%. A total of six were discarded for incompleteness/damage for an effective response rate of 197/945 or 20.8%. Considering that this is a lengthy survey, this response rate is acceptable and correlates well with recent empirical studies in operations management (OM) and supply chain management (SCM) (e.g., Paulraj & Chen, 2005, 23.2%; Krause et al., 2001, 19.6%).

Respondent and Firm ProfilesThe profile of the final sample of 197 in-

cluded top executives (17%), middle managers (73%), and others (10%). Almost half of the firms had been in business for over 30 years (48%) and most were engaged in end product manufacturing (49%), followed by subassembly (30%), components (19%), and others (2%). Firm size was fairly evenly distributed between large and small firms with respondents with sales of over $20B (6%), $1B~$20B (31%), $500M~$1B (30%), $100M~$500M (19%),

$10M~$100M (6%), and under $10M (8%). Most firms employed 500 or more employees (81%). The vast majority of the respondents were working on their first ERP system (78%) with some (22%) on their second or third system. Furthermore, most had not worked on multiple ERP systems (87%), but some had multiple systems in the same facility (13%). The distribution of the sample regarding respondent and firm profiles is presented in Tables 1 and 2, respectively.

rEsults And dIscussIonsExploratory factor analysis (EFA) was performed to empirically test the nine strategic ERP con-structs included in this study using the principle component method. Items with a factor loading of 0.3 or greater were retained for further analysis (Flynn, Schroeder, & Sakakibara, 1994; Hair, Anderson, Tatham, & Black, 1998). Reliability analyses were performed to test whether random measurement errors varied from one question to another (Judd, Smith, & Kidder, 1991). Reliabil-ity was measured using Cronbach’s alpha internal consistency method where reliability coefficients of 0.60 or higher are considered acceptable (Cron-bach, 1951). All of the reliability coefficients are greater than 0.658 after the removal of questions

All questions were analyzed using a seven point Likert scale with a score of 1 labeled ”not important,” a score of 4 labeled “neither important nor unimportant,” and a scale of 7 labeled “very important.” This study uses simple mean-based ranking of the indicators within each theoretical construct. Further analysis was conducted to provide additional insight into the results. The following sub-sections present the current state of practice for each of the theoretical constructs.

strategic InitiativesTable 3 presents the results for strategic initia-tives. The mean response for the seven indicators ranged from 5.33 to 5.79. This result is a pleasant surprise in that many researchers have written about ERP implementations being relegated to the information technology departments; to the contrary, this research shows that firms are now attaching a strategic component to their ERP implementations and that the decision to imple-ment an ERP system is now being made at a cross functional executive level which includes inputs from all functional business areas. Further, the respondents concur that the ERP implementation should be tied to achieving strategic goals. The fact that two-thirds (67%) of the respondents came from firms with sales in excess of $500 million may further explain the increased desire for a stra-tegic component. Larger firms have the resources to fully integrate ERP systems as opposed to just automating processes (Muscatello, 2002). These larger firms may have access to information and research that smaller firms do not and thus have common strategic goals and when goals are common, improvement becomes a shared task (Hill, 2000). The low standard deviation further shows the uniformity of this opinion.

Executive commitmentExecutive commitment has been documented to be of great importance in achieving any major business improvement project. The response to this survey re-confirms the need for executive

commitment for ERP implementations identi-fied by on past research. Seventy three percent (73%) of the respondents classified themselves as middle-managers and 17% classified them-selves as director or above. However, a test of the means between the respondents produced no discernable difference, verifying that all levels of management consider executive com-mitment important. Table 4 presents the results for executive commitment and support. The mean response for the seven indicators ranged from 4.68 to 5.53. The highest responses came from the question on long-term executive com-mitment showing the high regard they have for executives who realize the complexity and time commitment necessary for a successful implementation. The lowest indicator showed that while executives deemed the ERP imple-mentation very important, they still expected the operational concerns to be addressed in the interim.

human resourcesIndicator number 2, ‘low IT skills are an obstacle to successful ERP implementations’ and Indica-tor 3, ‘executives with little knowledge of ERP should be minimally involved’ were eliminated from the research to improve the Cronbach’s alpha to 0.677 from 0.606. The mean responses of the remaining six indicators ranged from 4.57 to 5.76 and are presented in table 5. From the human resource side, there appears to be strong commitment to gaining the knowledge required

to successfully implement ERP systems via training and education of current employees or hiring of outside consulting help. Significant re-search has noted that ERP education and training is required for successful implementation. This research offers a new insight: respondents saw little difference between gaining the knowledge via education and training or through consult-ing help. The lowest responses came from the idea of replacing ineffective employees or managers who are not able to adapt to the new system. This could present a problem in some smaller firms where key managers have multiple tasks. Possible explanations for the low response rate for employee replacement includes the reluctance of many firms to termi-nate people for incompetence if they are well liked and committed. It is noted that Hammer and Champy (1993) also openly reject the idea of eliminating jobs through reengineering. Thus, many managers and consultants may still hold true to this idea.

Project ManagementRespondents were asked about ERP project management issues including the responsibili-ties of project team members and the capabilities of the project leader. Table 6 presents the results for project management. The mean response for the seven indicators ranged from 5.51 to 5.64. This shows a strong commitment for project management skills in project definition, scope, tracking, and status. It reveals that project man-

agement skills were grossly underestimated in ERP implementation in the past and are now becoming a critical skill set for ever changing business needs. The fact that 81% of the re-sponding firms had more than 500 employees could also explain this response. Larger firms have more internal expertise to draw from and thus are more likely to be equipped with project management champions.

Information technologySoftware and hardware expertise has been docu-mented to be of great importance to a successful ERP implementation and this survey shows the same high level of importance with a range of the means from 5.41 to 5.69 with very low standard deviations. The results are presented in Table 7. Somewhat unique to this research is the attempt to find out the importance of the skill sets of the current information technology (IT) staff, which are deemed very important,

and the use of consultants if the skill sets are not internal. The results show that firms are willing to supplement their IT staff with consultants when necessary. This acceptance of outside help shows an understanding of internal limitations of a firm and a sense of urgency and willingness to acquire it externally.

business ProcessERP implementation has been referred to as an “organization wide revolution” due to the large number of changes it brings to an organization (Hammer & Stanton, 1999; Bingi et al., 1999). The strong connections that researchers have proposed between business process redesigns

and successful ERP implementation have been confirmed by our results. The means ranged from 5.45 to 5.74 with low standard deviations are presented in Table 8. Interestingly, the high means for all seven indicators suggest that the connec-tion researchers have preached is being accepted by the practitioners. Ross (1999) suggested that firms believed that ERP software would solve their problems by imposing discipline and process integration on their organization. This research confirms that practitioners now disagree with that assessment and realize that software is not a substitute for good business processes. The “business process” indicators indicate that process knowledge and redesign,

cross functional management and driving out inefficiencies that improve customer benefits are all strongly accepted as necessary for a successful implementation. Hammer and Champy’s (1993) work on reengineering and the wide-spread use of their practices as a change enabling tool helps confirm the positive use of reengineering in ERP implementations.

trainingThe importance of training was echoed by most of our respondents. As expected, based on cur-rent research, training was a highly regarded

component of ERP implementations. The means of the eight indicators ranged from 5.45 to 5.70 with low standard deviations and are presented in Table 9. Again, the question if external exper-tise in the form of consulting should be used to supplement internal knowledge was asked and the answer was strongly yes. Firms supported the need for formal, customized training on both ERP knowledge and specific job duties. They also strongly supported on-going educa-tion programs which has not always been the case for some firms who are risk adverse. The high percentage of respondents in larger firms

(81% had 500 or more employees, and 86% had sales over $100 million) may explain the high level of interest in outside consulting help, since larger firms usually have greater access to resources. Smaller firms, without the access to ERP resources, need to establish whether or not they can obtain the resources or postpone the implementation since it is documented that overcoming an ERP failure is difficult and often fatal (Muscatello et al, 2003).

Project support and communicationsLack of strong support for a massive project like ERP creates enormous challenges for the project team such as buy-in from users. A recent study revealed that 25% of organizations adopting ERP systems faced significant resistance from staff and that 10% of the organizations also encountered resistance from managers (Ku-mar et al., 2003). Table 10 presents the results for project support and communication. The means range from 5.57 to 5.86. This research supports extant research on employee relations and change management in that the respondents felt it very important to actively communicate how employees fit into the new ERP-oriented environment and to actively work to alleviate employee concerns. Respondents also agree that cultural changes need to be managed to ensure shared values and common aims conducive to both employee and firm success. A user support group with employee comments and reactions

should be used to help employees manage through the cultural changes.

software selection and supportEven with today’s state of the art technology, organizations find that not all their requirements are met by the ERP systems they adopt. The remaining nine indicators are strong with means from 5.64 to 5.86 and the results are presented in Table 11. These indicators confirm current re-search that shows a strong relationship between successful ERP implementations and software fit. Interestingly, the research again confirms that firms are willing to use outside consultants if software selection experience is not available internally. Again, this set of indicators show a new willingness amongst ERP implementers to realize their firm’s limitations in this difficult endeavor. Also of note is a strong resolve to work with vendors to ensure proper module and process fit, as well as vigorous software testing, troubleshooting, and a plan for migrating and data clean up after the initial installation.

conclusIonEnterprise resource planning systems have experienced a phenomenal growth over the past decade. While some firms declared their ERP implementation success, many others reported negative results. With these developments, there has been a significant amount of research that seeks to identify the success factors associated

with the implementation of ERP systems. Most of these authors, however, have based their re-search on a small number of case studies. This study, therefore, aimed to understand the critical constructs of ERP implementation using a large scale survey. A cross sectional mail survey of business executives with ERP implementation experience was used to capture the degree of adoption of these concepts. Basic statistical methodology was used on this empirical data to examine the adaptation of the various concepts. Although this analysis was based on simple statistical methods, it provides a clear picture of the beliefs of current ERP implementation. These constructs can also help guide future research for academics and practitioners in the ERP environment.

In summary, the results show that the implementation of ERP systems has grown from the belief that it was a simple information system implementation of new software into a realization that it is a strategic and tactical revolution which requires a total commitment from all involved. This is in stark contrast to studies as recent as 5 years ago, which concluded that firms believed that the ERP software would automatically drive the strategic and tactical changes. Firms now realize that business process changes and project management are strongly

linked to the success of the ERP implementation. Moreover, they are as important as software and hardware knowledge. Another new finding is that firms now strongly believe that the use of outside consultants to supplement internal staff is an acceptable and desirable practice. This is likely a result of the documented cases of ERP implementation failure where firms failed to take stock of their internal competen-cies and shortcomings. Taken together, these results suggest that firms are realizing that ERP implementations are a long journey and that results may not be readily apparent until well into the future.

This research has provided insight into the current practice of ERP implementations. It has paved a solid foundation on which to build future research in this area. Nevertheless, it is realized that this effort cannot completely explain all of the issues surrounding an ERP implementation. Additional insights may be revealed through longitudinal studies and by building empirical models.
