And then you wind up designing to those bullet points, not to humans. A feature is signed off and agreed on. So what should you do in place of a spec? Go with a briefer alternative that moves you toward something real. Write a one page story about what the app needs to do.
Use plain language and make it quick. Then begin building the interface — the interface will be the alternative to the functional spec. In the absence of standards, you get to define your own. Believe me, I know from some personal, painful experiences. And no matter what specification format you use to document your functional requirements, ensuring you get the right requirements requires use case thinking, often with corresponding wireframes.
When you think in terms of the interchange of a user and system interaction, you will get to the right level of detail in your software requirements and often discover requirements that otherwise will often get missed.

When it comes to requirements generation and functional specification documentation, you can also use a prototyping tool, such as Justinmind. Because prototyping tools are used before source code is written, the ability to generate documentation automatically is both useful and quick. The widgets you place on your canvas can be turned into requirements, simply by right clicking on them. These features enable teams to work in a truly collaborative manner, which is handy if you ever want to reach a consensus.
To give your entire team full visibility and enhance collaboration, Justinmind lets you effortlessly integrate with JIRA, too. Best practice tells us that generating documentation will save you time, money and possibly work relationships.

Sit down with important members of your team. Even after being validated, a specification continues to change, because while implementing the features, developers and testers will pinpoint a multitude of special cases or functional inconsistencies that you were absolutely certain you got right! No matter how you choose to do it, keep in mind that the best specifications are those that ease the software production process.

Patrice Lamarque. Make it a collaborative contract In a software production organization, the functional specifications play the role of a written contract between the key stakeholders that collaborate in the making of the software.
Designers should define the user interface and interactions. QA should be able to find enough information in the document to reflect the changes in tests. Developers should find sufficient explanation to help them define technical specifications or directly code the corresponding features.
Technical writers should find answers to help them write meaningful user manuals and technical documentation.
