Question

Q2) Answer with details :

a - What are the four requirements engineering activities?

b- What are the incremental delivery advantages?

Answer 1

Ans a) Following are the four main activities:

· Requirements elicitation.

· Requirements specification.

· Requirements verification and validation.

· Requirements management.

Requirements Elicitation:

· This is related to the different way by which we can obtain some knowledge or idea about the basic requirements.

· This idea is linked with the domain like customers.

· This activity consists of some process like interviews, analysis of job etc.

· It acts like a door for the next stage.

Requirement Specification:

· This activity requires more ideas or knowledge about the domain.

· The specification of functional, non-functional requirements is done by this activity.

· ER diagrams, DFDs etc. have been made.

Requirements Verification:

· Verification: These are the processes which checks the software functions are working properly or not.

· Validation: These are the processes which check that software fulfills the customers need or not.

Requirements management:

   It includes the following processes:

· Analysis

· Documentation.

· Agreements etc.

Requirement management is the management of software at every stage. It makes software to change their features according to the user need in a controlled manner.

Ans b)

Following are the advantages of incremental delivery:

· The pre-increments act as prototypes for the customer, so that it provides some experience.

· It provides the values before the process completed.
