3. Introduction
To quote the words of Jankowicz (2005, p. 161): “…the work that you do is not done in a vacuum, but builds on the ideas of other people who have studied the field before you. This requires you describe what has been published, and to marshal the information in a relevant and critical way” Whatever the objective(s) of a research may be, its significance is invariably judged in relation to other peoples research and findings. Therefore, one really needs to demonstrate awareness of the current state of knowledge in the chosen area of research and show how his/her research fits into the wider context (Gill and Johnson, 2002). This can be achieved through a literature review.

4. What is Literature Review?
A literature review is a part of the research report where the researcher analyzes and discusses published/scholarly information relating to the subject area under research.
A literature review surveys scholarly articles, books and other sources (e.g. dissertations, conference proceedings) relevant to a particular issue, area of research, or theory by providing a description, summary, and critical evaluation of each work.

5. What is Literature Review Cont’d
It is a critical and evaluative account of what has been published on a chosen research topic.
Its purpose is to summarise, synthesise and analyse the arguments of others.
You should describe and analyse the knowledge that exists and what gaps occur in research related to your field of interest. (This should clarify the relationship between your own research and the work that has previously been done.)
It should reveal similarities and differences, consistencies and inconsistencies and controversies in previous research.

6. What Literature Review is not
It is not primarily an argument for the importance of what it is you are researching. While it is necessary to explain what is the primary purpose of your research, the reader of a literature review will assume that the need for undertaking the research has already been established.
It is not a descriptive list of papers or summaries. You must not just list your sources and describe them in detail one at a time.
A literature review is organised around ideas, not the sources themselves as an annotated bibliography would be organised. You should assess previous studies and discuss their strengths and weaknesses.

7. Forms of Literature Review
Two forms of literature review are usually conducted for different reasons (Sharp et al, 2002)
The preliminary review which helps the researcher to generate and refine research ideas. This review usually does not form part of the research project proper
The critical review, which forms part of the research project, helps the researcher

8. The Purpose of the Critical Literature Review
Reviewing the literature critically provides the foundation on which a research is built.
The precise purpose of reviewing the literature will depend on the approach used in the research.
Deductive approach: The literature is used to identify the theories and ideas that will be tested using data
Inductive approach: the literature review helps you relate your findings to existing knowledge.

9. Reasons for conducting Literature Review
Literature review may be conducted for a number of reasons. These include:
Literature review offers an overview of significant literature published on a topic
To help you refine further your research questions and objectives
To highlight research possibilities that have been overlooked implicitly in research to date. That it helps to identify knowledge gaps
To discover explicit recommendation for further research. These can provide you with an excellent justification for your own research questions and objectives

10. Reasons for conducting Literature Review Cont’d
To help avoid simply repeating work that has been done already
To sample current opinions in newspapers, professional and trade journals, thereby gaining insights into the aspects of your research questions and objectives that are considered newsworthy
To discover and provide an insight into research approaches, strategies and techniques that may be appropriate to your own research questions and objectives

11. Literature Review Process
The process can be likened to an upward spiral culminating into the final draft of a written critical review. The processes are:
State the research problem/questions and objectives
Define the parameters for your search
Generate and refine key words for the search
Conduct literature search
Obtain literature
Evaluate the literature: determine which literature makes a significant contribution to the understanding of your work
Record the relevant literature
Start drafting the literature review: this should involve description, analysis and synthesis
The process may be repeated a number of time to come out with a critical review report

12. Conducting the Literature Review
Literature reviews should comprise the following elements:
An overview of the subject, issue or theory under consideration, along with the objectives of the literature review
Division of works under review into categories (e.g. those in support of a particular position, those against, and those offering alternative theses entirely)
Explanation of how each work is similar to and how it varies from the others
Conclusions as to which pieces are best considered in their argument, are most convincing of their opinions, and make the greatest contribution to the understanding and development of their area of research

13. The Content of Critical Literature Review
The content of the critical literature review need:
To include the key academic theories within your chosen area of research
To include relevant empirical research conducted on the chosen area
To demonstrate your knowledge of your chosen area is up to date
Show clear referencing which will enable those reading your project report to find the original publications you cite

14. Evaluating the Content of Critical Literature Review
Ask if you have:
shown how your research question relates to previous research reviewed
assessed the strengths and weaknesses of the previous research reviewed
been objective in your discussion and assessment of other people’s research
included references that is counter to your our opinion
made reasoned judgements about the value and relevance of others’ research to your own
highlighted those areas where new research (yours!) is needed to provide fresh insights and taken into account in your arguments.
justified clearly your own ideas

15. The Structure of the Critical Review
Three common structures are identified. The literature review can be written in:
A single chapter
A series of chapters
Throughout the project report as you tackle various issues
For dissertation, adopt a single chapter approach with the following components:
Introduction
Theoretical and
Empirical
Concepts, Constructs and Operational definitions

16. Conducting Theoretical Review
Theoretical literature refers to the various theories or abstractions expressing the ideas and concepts on a subject matter.
To conduct a theoretical literature review:
Identify the key themes
Identify your variables of interest if any
Identify and discuss the theories bordering on the variables
Synthesize and evaluate these theories with respect to your hypothesis or proposition, or thesis or research question

17. Conducting Theoretical Review Cont’d
Create a mind-map of the theories to write about
Convert the mind-map into a story-board or an outline
Get the necessary information and synthesize and evaluate under each sub-theme or theory.
Relate these to your hypothesis or proposition or research question.

18. Sources of Information for Theoretical Literature Review
Text Books
Book Reviews
Peer reviewed Journals
Accredited scholarly publications
Web (scholarly search engines)

19. Empirical Literature Review
After the theoretical literature look for published scholarly research evidence in respect of the key theories in you work. Discuss whether they support your hypothesis or counter your hypothesis or emergent views and arguments.

20. Concepts and Constructs
A Concept is a generally accepted collection of meanings or characteristics associated with certain phenomenon, events, objects, conditions, situations or behaviors.
Eg. Employee performance, customer satisfaction, quality, strategic management, strategic leadership.
A Construct is an image or idea specifically invented for a given research and or theory building purpose.
E.g. Job Satisfaction: Job satisfaction is defined as "the extent to which people like (satisfaction) or dislike (dissatisfaction) their jobs" (Spector, 1997, p. 2

21. Operational Definition
An operational definition is a definition stated in terms specific testing or measurement criteria.
These terms must have empirical referents that we must be able to count or in some other way gather information through.
The definition must specify the characteristic and how they are to be observed.
The specifications and characteristics must be so clear that any one using it will classify the objects the same way
E.g. “…..and Job Satisfaction will be measured by or operationalized by ……..”

22. Presentation of the Literature Review
Three different approaches can be adopted if there are no institutional regulation or requirement. These are:
Chronological: present the information according to when they were published [from the most recent to the earliest or vice versa]
Thematic: information is organized along topic(s) or issue(s), rather than the progression of time. However, progression of time may still be an important factor in a thematic review.
Methodological: presentation focuses on the "methods" or “strategies” the researchers or writer used

23. Planning your Literature Search Strategy
The planning should include:
The parameters of your search
The key words and search terms you intend to use
The databases and search engines you intend to use
The criteria you intend to use to select the relevant and useful studies from all the items you find

24. Defining the Parameters of your search
You need to be clear on the following:
Language of publication
Subject area
Business sector
Geographical area
Publication period
Literature type

25. Generating your Key words
Could use one or a number of different techniques in combination:
Discussion with colleagues, your project tutor and handbook
Initial reading
Dictionaries, thesauruses, encyclopedias and handbook
Mind mapping
Brainstorming
Relevance tree

26. Conducting your literature search
The literature search could be conducted using a variety of approaches:
Tertiary literature sources
Literature referenced in books and journals
Scanning and browsing secondary literature in your library
Searching using the internet

27. Sources of Information
Untested opinion
Self-evident truth
Authoritative source (documents from authoritative sources)
Literary works
Scientific method
postulations

28. Sources of Literature Primary Tertiary Secondary Reports Theses
, Memos, minutes
Conference proceedings
Company reports
Unpublished manuscript sources
Some government publications such as white paper etc.
Books
Journals
Newspapers
Some government Publications
Indexes
Abstracts
Catalogues
Encyclopedia
Dictionaries
Bibliographies
Citation Indexes

29. Evaluating the Literature
Evaluating the literature gathered involve defining the scope of your review and assessing the value of the items that you have obtained in helping you to answer your research questions. Ask yourself the following questions:
Relevance
How recent is the item?
Is the item likely to have been superseded?
Are the research questions or objectives sufficiently close to your own to make it relevant to your own research?
Is the context sufficiently different to make it marginal to your research questions and objectives?
Have you seen references to this item (or its authors) in other items that were useful?
Does the item support or contradict your arguments?
Value
Does the item appear to be biased?
What are the methodological omissions within the work?
Is the precision sufficient?
Does the item provide guidance for future research?
