Introduction SE , the subject of large volume. plays significant role in SDLC. Requirement means any thing you want to get

Engeenring means to design and buildsomething like machines etc.

RE , a process, identifying a goal and

evaluate the needs of stake holders

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 theproposed system other activities are concerned with the solution of the problem and the behavior of the system

under these requirements. Furthermore, different factors

Observation during this research.

• 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.

• The main work of RE is concerned with static elicitation,

representation, and analysis of requirements.

21

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

22

3. Level three, associated with human and related to theprevious level by determining the adaption elements of theadaptive system.4. Level four, also done by human and associated with thegeneral understanding systems and events.

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.

26

• Lots of solutions and models have been developed

addressing specific contexts and scenarios, sharing this knowledge through standardized channels…

27

• More attention should be given to evaluation-based and

empirical research

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

DemeritsTime 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.
