Marketing people ignore those. Programmers use them. Yeah Right….. This approach is why most Software requirements specifications have such a bad reputation. Specifications should be updated frequently. The updating continues as the product is developed and new decisions are made. The software requirement specification always reflects our best collective understanding of how the product is going to work. The software requirement specification is only frozen when the product is code complete The software requirement specification should not be released daily.
Congruency between the customers stakeholders and the suppliers on what the software product is to do. The complete description of the functions to be performed by the software specified in the Software Requirement Specification will help the potential users to determine if the software in question adheres to their needs. Reduce the development effort. Careful review of the requirements in the Software Requirement Specification can reveal omissions, misunderstandings, and inconsistencies early in the development cycle when these problems are easier to correct.
Provide a basis for estimating costs and schedules. The description of the product to be developed as given in the Software Requirement Specification is a realistic basis for estimating project costs and can be used to obtain approval for bids or price estimates.
Provide a baseline for validation and verification. Organizations can develop their validation and Verification plans much more productively from a good Software Requirement Specification. As a part of the development contract, the SRS provides a baseline against which compliance can be measured.
Facilitate transfer. The Software Requirement Specification makes it easier to transfer the software product to new users or new machines. Customers thus find it easier to transfer the software to other parts of their organization, and suppliers find it easier to transfer it to new customers. Serve as a basis for enhancement. Because the Software Requirement Specification discusses the product but not the project that developed it, the SRS serves as a basis for later enhancement of the finished product.
The SRS may need to be altered, but it does provide a foundation for continued production evaluation. This is the most challenging task of the whole process.

What tools do you use? What format? What sort of style should you adopt?

Edit and ReWrite Rewriting and editing are, literally, half the battle. When setting the timeline for your completion of the software requirement specification, always try to add a week more than you originally anticipated.
What typically occurs is that something always comes up during the editing process. It is important that the software requirement specification is clean, but not perfect. Ideally, no spelling errors, no grammatical errors, no logic errors, and no mock up errors either.
Why not perfect? Time is of the essence. Edit from beginning to end at least three times after you think it is done Three times seems to usually do the trick…sometimes more is required, but never less. Without a document that describes all the software requirements, a project is likely to result in an enormous waste of money, effort, and time.
