7. What is Research?
• Research is:
“…the systematic process of collecting and
analyzing information (data) in order to increase
our understanding of the phenomenon about
which we are concerned or interested”
Research Methodology in CS & IT: Lecture 1
7

8. What is Research?
• Science develops through some systematic
observation, measurementation,
experimentation, and interpretation
procedure called “research”.
• Thus, research is the most important, if not
the only tool for development of science.
Research Methodology in CS & IT: Lecture 1
8

9. • “Research can be described as a systematic and
organized effort to investigate a specific problem that
needs a solution” (Sekaran 1992, p.4).
• Keywords:
1. Systematic (Methodical) and organized (planned)
2. It encompasses the processes of inquiring /
investigating – end result would help to solve
problems or suggest ways to solve problems.

10. More Understanding on What is
Research ?
• Research is a careful and systematic process of inquiry
to find answers to problem of interest.
• Research include:
– use of facts,
– use of theories,
– data (fact) analysis,
– sampling,
– doing an experiment,
– going to library to read up on a topic.
• To do ‘research’ is to investigate the problem
systematically and thoroughly.
• Goal of research is to solve ‘problem’ of interest

11. Research Characteristics
1. Originates with a question or problem.
2. Requires clear articulation of a goal.
3. Follows a specific plan or procedure.
4. Often divides main problem into subproblems.
5. Guided by specific problem, question, or
hypothesis.
6. Requires collection and interpretation of data.
7. Cyclical (helical) in nature.

12. The Aims of Research
• To describe about a phenomena
• To predict about “something” in the future
• To explain about solution of problem
• To interpret what is being investigate
Research Methodology in CS & IT: Lecture 1

13. Research environment
• Research is conducted mainly in the following
institutions all-over the world:
- Government or private research
institutions.
- Research and development (R&D) units
of big companies.
- Research in the universities.
Research Methodology in CS & IT: Lecture 1

14. Characteristics of research Process
Research is:
• controlled.
• rigorous (strictly accurate).
• systematic.
• empirical.
• innovative.
• usually expensive.
• Research outcomes are valid and verifiable.

15. What is IT/Computer Science Research?
• A human activity based on the intellectual
investigation of aspects of the world related to
the discipline of IT/Computer Science for the
purpose of:
– discovering new knowledge,
– interpreting existing knowledge or
– revising inaccurate or incomplete knowledge.
Research Methodology in CS & IT: Lecture 1
15

16. What is Computer Science?
• The body of knowledge resulting from this
discipline contains theories for understanding:
– computing systems and methods;
– design methodology, algorithms, and tools;
– methods for the testing of concepts;
– methods of analysis and verification; and
– knowledge representation and implementation.

17. Scientific Methods
• “Methods” means way
• Methodology is the discipline of scientific
procedures.
Research Methodology in CS & IT: Lecture 1
17

18. What is Methodology ?
• A formalized approach to conduct research
– A series of phases and deliverables.
• Research Methodology In Computer
Science/Information System/Information
Technology (CS/IS/IT)
“A collection of methods, procedures,
techniques, tools and documentation aids which
will help the researcher in their efforts to
conduct a research in the field of CS/IS/IT”.

19. Research Methodology Vs. Research
Method
• Research Methodology:
– Conceptual frameworks and assumptions
used to inform research
– Elaboration of research method
• Research Method:
– Research technique or procedure used to
gather and analyze data
Research Methodology in CS & IT: Lecture 1

20. Research Methodology
• A research methodology will consist of phases,
sub-phases, which will guide the researchers
in their choice of the methods, techniques,
procedures, tools, etc., that might be
appropriate at each stage of the research and
also help them plan, manage, control and
evaluate the progress of research.
Research Methodology in CS & IT: Lecture 1
20

21. • A research methodology represents a way to
develop research systematically.
• A research methodology represents a way to
do scientific inquiry.
• A research methodology should have a sound
theoretical basis.
Research Methodology in CS & IT: Lecture 1
21

22. Why Methodology ?
• It will make you better able to understand and
utilize scientific information in both your
personal life and your work.
• It will make you a more literate and cultured
person.
• It provides you some insight not only into
particular scientific findings but also into
the general nature of science as a human
activity.
Research Methodology in CS & IT: Lecture 1
22

23. Nature of Research in CS/IS/IT
• Research in CS often requires experimental design as well as
theoretical (basic) research
– Hence, we have to have a methodology in order to
conduct research
– Science approach :new knowledge, theory
• Research in IS/IT often requires system development
– Hence, we have to have a methodology in order to
develop a system (IS/IT system)
– Engineering approach: construction of useful
products
• This IS/IT Development Methodology can be used as a
Research Methodology in IS/IT field.
Research Methodology in CS & IT: Lecture 1
23

24. How to Start A Research?
• Determine a well define problem
– Understanding about something
• Science approach: phenomena, theory, hypothesis,
experiment..
– Constructing product
• Engineering approach: build a system that perform a
(unique) task, experiment, convergence results
(stable)..
• Follow the steps in the research methodology
• Research results: knowledge, algorithm, method, technique,
approach, framework, product (system), model, etc…

25. Problem Formulation

26. What does Research in degree studies
involve?
• Doing secondary research i.e. familiarising yourself
with the work of “experts” – this process is known as
a Literature Review.
• Doing a primary research – to build upon what you
have already found out about a subject.
• Comparing the findings and drawing your own
conclusions.
• So, Diploma/ Master/ PhD ?
Research Methodology in CS & IT: Lecture 1

27. The research – How !!!!
• Start with a question
• State a goal
• Form a plan
• Formulate experiments and hypotheses
• Make and state important assumptions
• Collect and interpret data
• Research doesn’t happen in straight lines
Research Methodology in CS & IT: Lecture 1
27

28. Purpose of Research
Two purposes:
1. To generate more knowledge and understanding of
the phenomena of interest and to build theories
based on the research results.
- Basic Research
Example: The public’s opinion of the effectiveness
of its Police Department in tracking people
released on bail (financial guarantee)..
Research Methodology in CS & IT: Lecture 1
28

29. 2. To solve a current problem faced by the manager in
the work setting, demanding a timely solution.
- Applied Research
Example: The Police Department has asked a
research company to come up with a new system
of tracking people released on bail.

2. Preliminary information gathering (Informal
Secondary Research)
3. Literature Review (formal secondary research)
4. Hypothesising
5. Further data collection (Primary Research)
6. Data analysis
7. Deduction (conclusion)
8. Writing the report/ article/ thesis …

33. Originality in research
• Originality is a "must" in research.
• It is a high-profile requirement.
• You should develop the necessary skills to
recognize "what is original?" and implement it
into your work.
• It may need a considerable incubation period for
the creative skills to function effectively in
development of originality in your research.
• You need to appreciate the scope and potential
of originality.

34. The research process: an eight-step model
• Phase I: deciding what to research
– Step I: formulating a research problem
• Phase II: planning a research study
– Step II: conceptualizing a research design
– Step III: constructing an instrument for data collection
– Step IV: selecting a sample
– Step V: writing a research proposal
• Phase III: conducting a research study
– Step VI: collecting data
– Step VII: processing and displaying data
– Step VIII: writing a research report
