Requirements Management Through
SDLC
12.1 Introduction
While establishment of requirements is among the first activities in the software
development life cycle, requirements need to be managed through the SDLC
(Software Development Life Cycle) to ensure that all the customer requirements
are included in the final deliverable. To do so, we need to include the additional
requirements received through the change requests, delete the requirements that
are eliminated through change requests and modify the requirements modified
through the change requests.
But, the industry does not have a single standardized SDLC and in fact, there
are multiple SDLCs. Here are some of the popular SDLCs:
1. Water fall model
2. Spiral model
3. RAD and JAD
4. Iterative model
5. Agile methods
a. XP
b. Scrum
c. RUP agile version
d. Many more
There are many SDLCs out there in the software development industry. While a
detailed discussion of all the life cycles out there is out of scope for this topic, the
following phases are commonly part of any SDLC:
1. Requirements
2. Software Design
3. Construction
4. Testing
