What is Software Requirement Specification (SRS)?

Software requirement specification (SRS) is a complete document or description of the requirements of a system or software application. In other words, “SRS is a document that describes what the features of the software will be and what its behaviour will be, i.e. how it will perform.” The advantage of SRS is that it takes less time and effort for developers to develop software. What SRS is is like the layout of the software which the user can review and see whether it (SRS) is made according to his needs or not. We learned about software requirement specification, what it is, now let us read its features....

Importance of Software Requirements Specification (SRS):

1. Clarity and Understanding:...

Characteristics of Software Requirements Specification (SRS):

Complete: The SRS should be complete i.e. all the software requirements should be mentioned in the SRS. Correct: It should be correct i.e. it should be according to the needs of the customer. Clear: It should be clear. The requirements of the software should be clearly declared. Accurate: It should have accuracy. If this is not accurate then the software cannot be developed. Consistent: It should be consistent from beginning to end so that users can easily understand the requirements. And consistency can be achieved only when there is no contradiction between the two requirements. Verifiable: It should be verifiable. The requirements are verified by experts and testers. Modifiable: All the requirements specified in the SRS document should be modifiable. This can happen only when the structure of SRS is balanced. Traceable: It should be traceable, that is, each requirement in it should be identified differently. Each requirement should have its own identity. Testable: It should be testable i.e. it should be capable of being tested in any way. Unambiguous: It can be unambiguous only when all the requirements have only one meaning. That is, there should be only one interpretation....

Conclusion:

So, the Software Requirements Specification is an important part of successful software development projects. This all-encompassing guide brings together stakeholders, helps in project planning and directs development activities. Whatever the changes, in the end it makes client satisfaction its own. Ignoring the importance of a correct SRS can there- fore mean project failure, increased costs in development, and dissatisfied stakeholders. Therefore developing a powerful SRS is the first step on the road to success, for any software developer worthy of his salt....
