Unless you live in a world filled with unicorns and rainbows, writing realistic requirements is critical. When you set unattainable goals, the best result you can hope for is a frustrated engineering team. Write requirements that are attainable, and your team will surprise you with what they can achieve.

Design-Free requirements are important for two reasons, and hard for two other reasons.
Design-free requirements are hard because you “know what you want” when you should be documenting “why you want it.” Writing design-free requirements can be hard when you don’t trust your development team to “do the right thing” even though it is not your job to design the solution.

- Identify the problems that need to be solved.
- Explain why those problems are worth solving.
- Define when those problems are solved.

- Valuable requirements solve problems in your market.
- Valuable requirements support your business strategy.
- Valuable requirements solve problems for your users.
- Valuable requirements meet your buyers’ criteria.
- Valuable requirements don’t over-solve the problems.

User stories can make requirements management a lot easier. They shift some of the communication from up-front documentation to ongoing dialog. That’s the main reason they work so well for agile teams. And agile teams focus on “what’s next?” instead of an ever-changing “what’s everything?” The problem is, when those conversations are working well, it is easy to forget to make sure that what you’ve done is actually enough. Add a small dose of traceability, and you can easily validate the completeness of your user stories.
