SE , the subject of large volume.
plays significant role in SDLC.
Requirement means any thing you want to get
Engeenring means to design and build
something like machines etc.
RE , a process, identifying a
goal and evaluate the needs of
stake holders

16. Introduction
Requirement engineering activities differs from
other software.
engineering activities as they are concerned with
identifying the problem
how the environment will be affected by the
proposed system
other activities are concerned with the solution of the
problem and the behavior of the system
under these requirements. Furthermore, different factors

20. • The main work of RE is concerned
with static elicitation,
representation, and
analysis of
requirements.
• One of the remarkable works on this field was
carried out by
Berry et al. [36]. They suggested four levels
of RE activities
needed to support adaptive systems.
20

21. 1. Level one, associated with human and
related to activities
associated with elicitation and analysis of
requirements.
2. Level two, associated with the system
when it is running and
its ability to adapt according to various
inputs and behaviors.
21

22. 3. Level three, associated with
human and related to the
previous level by determining the
adaption elements of the
adaptive system.
4. Level four, also done by
human and associated with the
general understanding systems
and events.

24. 1. Requirement engineering field is very huge,
the need to
have some sort of centralized repository or
index to the
work in this field can help researchers utilize
research time in evaluating work and find
solutions.

25. •
•
The gap between
researchers and
practitioners should
be minimized.
collaborative efforts between
them will help researchers obtain
a better understanding of
problems and challenges.
25

26. •
Lots of solutions and
models have been
developed
addressing specific
contexts and
scenarios, sharing this
knowledge through
standardized
channels…
26

27. •
More attention should
be given to evaluationbased and
empirical research

30. Merits
 Elicitation techniques are really helpful for
collection rich information about the requirements.
 The observational methods provide vital
information for designing solution.
 R.E used some techniques that are really helpful
for collection rich information about the
requirements.
 R.E techniques bring certainty in the
requirement

31. Demerits
Time consuming.
A small mistake or fact ignorance
in analysis gives a great error.
 User cant b explain there ideas due
to lake of knowledge .
 Difference of knowledge between
user and analyst.
