LITERATURE REVIEW
13
![Page 14: presentation literature review - Welcome - BeeP · new primary scholarship itself. The primary reports used in the literature may be verbal, but in the vast majority of cases reports](https://reader034.vdocuments.net/reader034/viewer/2022050406/5f82ff5a0227bf5f3e478c94/html5/thumbnails/14.jpg)
Literature review: general concepts
14
•Critical and evaluative report of what has been published on a topic •Aimed at summarizing,
synthesizing and analyzing arguments of others.
•Description and analysis of extant knowledge and detection of gaps in research related to your field of
interest•Reveals similarities and
differences, consistencies and inconsistencies and controversies
in previous research.
•A descriptive list of papers or summaries•A procedure to look for the “best
contribution”•A non value-adding activity
•A way to conclude that a topic is interesting
![Page 15: presentation literature review - Welcome - BeeP · new primary scholarship itself. The primary reports used in the literature may be verbal, but in the vast majority of cases reports](https://reader034.vdocuments.net/reader034/viewer/2022050406/5f82ff5a0227bf5f3e478c94/html5/thumbnails/15.jpg)
Literature review: a description/definition
“A literature review uses as its database reports of primary or original scholarship, and does not report
new primary scholarship itself. The primary reports
used in the literature may be verbal, but in the vast majority of cases reports are written documents. The
types of scholarship may be empirical, theoretical, critical/analytic, or methodological in nature. Second
a literature review seeks to describe, summarize, evaluate, clarify and/or integrate the content of
primary reports“
(Cooper, 1988)
15
![Page 16: presentation literature review - Welcome - BeeP · new primary scholarship itself. The primary reports used in the literature may be verbal, but in the vast majority of cases reports](https://reader034.vdocuments.net/reader034/viewer/2022050406/5f82ff5a0227bf5f3e478c94/html5/thumbnails/16.jpg)
…hence
• A literature review provides research stakeholders with a twofold outcome:
– Informs about extant wisdom on a topic, by presenting an evidence-informed summary of the results accomplished on specific issues
– Highlights blank or weakly covered areas for grounding incremental studies in the field, justifying further research efforts.

The primary reports used in the literature may be verbal, but in the vast majority of cases reports](https://reader034.vdocuments.net/reader034/viewer/2022050406/5f82ff5a0227bf5f3e478c94/html5/thumbnails/17.jpg)
How to approach a literature review
17
![Page 18: presentation literature review - Welcome - BeeP · new primary scholarship itself. The primary reports used in the literature may be verbal, but in the vast majority of cases reports](https://reader034.vdocuments.net/reader034/viewer/2022050406/5f82ff5a0227bf5f3e478c94/html5/thumbnails/18.jpg)
Problem formulation
• Identification of a relevant problem in the extant managerial or research domain
• It is not an argument for a position or an opinion
18
Good problem statement:“I want to understand how do
marketing and supply chain
management manage their
interfunctional interface”
Bad problem statement:“I want to demonstrate that
marketing and supply chain
management should interact
more than they do”

Choice of the review model
19
Narrative/incremental (“snow puppet”) review
Systematic review
![Page 20: presentation literature review - Welcome - BeeP · new primary scholarship itself. The primary reports used in the literature may be verbal, but in the vast majority of cases reports](https://reader034.vdocuments.net/reader034/viewer/2022050406/5f82ff5a0227bf5f3e478c94/html5/thumbnails/20.jpg)

Narrative/incremental review
21
![Page 22: presentation literature review - Welcome - BeeP · new primary scholarship itself. The primary reports used in the literature may be verbal, but in the vast majority of cases reports](https://reader034.vdocuments.net/reader034/viewer/2022050406/5f82ff5a0227bf5f3e478c94/html5/thumbnails/22.jpg)
Narrative/incremental review: strengths and weaknesses
Thumb up
• Generally accepted as the mainstream approach
in management
• Creative, potentially richer in results
Thumb down
• The principles for the inclusion of contributions
in the review are affected
by the implicit biases of the researcher
22
![Page 23: presentation literature review - Welcome - BeeP · new primary scholarship itself.

Systematic review: characteristics
• development of clear and precise aims and objectives
• pre-planned methods
• comprehensive search of all potentially relevant articles
• use of explicit, reproducible criteria in the selection of articles for review
• appraisal of the quality of the research and the strength of thefindings
• synthesis of individual studies using an explicit analytic framework
• balanced, impartial and comprehensible presentation of the results.

Descriptive review
• “Quantitative” review, based on the number of papers/sources published under certain
circumstances
• Useful to emphasize the growth in the debate, the
main contributors, the most/least developed issues,
etc.
• It is a part of the story. Not the story

Possible frames for literature reviews (adapted from: Carnwell and Daly 2001)
Approach Definition Advantages/Disadvantages
Identifying streams (e.g. themes or categories)
Discussion theme by theme Most popular
Empirical/theoretical
comparison
Themes must be clearly
related to literature
Chronological review Literature divided into time
periods
Suited to describe the
evolution of a phenomenon
Theoretical review Discussion of theoretical literature
followed by exploration of
methodological literature to
conclude about te research
design most suited to study the
topic
Useful when literature is
largely theoretical with little or
no empirical literature
Splitting theoretical and
empirical contributions
Discussing theoretical debate and
empirical findings separately
Tends to be more a
description than a critical
review
32

Conclusions
• Whatever the method, a literature review must be consistent, trustworthy, original and rigorous
• The magic question: “if someone else had started
from the same sources, would he/she have reached
the same outcomes?”
• This does not mean that there is not creativity!
