Software requirement specification
SRS document generates all necessary requirement while project development.For deriving requirement we need to have clear and through understanding of the products to be developed.This prepared after detailed communication with project team and costumer.
An SRS clearly defines following:
1.External interfaces of the system: They identify the information which is to flow 'from and to' the system.
2.Functional and nonfunctional requirements of the systems. They stand for the finding of run-time requirements.
3.design constraints.
The SRS outline is given below:
1.Introduction
1.1 purpose
1.2 scope
1.3 definitions,acronyms and abbreviations
1.4 references
1.5 overview
2. Overall Descriptions
2.1 product perspective
2.2 product functions
2.3 user characteristcis
2.4 constraints
2.5 assumptions and dependencies
3.Specific requirements
3.1 External interfaces
3.2 functional requirements
3.3 performance requirements
3.4 logical database requirements
3.5 Design constraints
3.6 Software system attributes.
3.7 organising the specific requirements
3.8 additional comments
4. supporting information
4.1 table of contents and index
4.2 appendixes
