Specifying Good Requirements

Donald Firesmith has written an excellent article on Requirements Specifications. (Thanks to Jonathan Babcock for highlighting this article.)

"Many of the characteristics of properly specified requirements have been well known for many years, at least among professional requirements engineers. Yet most requirements specifications seen today in industry still include many poor-quality requirements.

"Far too many requirements are ambiguous, incomplete, inconsistent, incorrect, infeasible, unusable, and/or not verifiable (e.g., not testable). To combat this sad state of affairs, this column provides a questionnaire that can be used when specifying and technically evaluating requirements."

Firesmith's article is a great starting point for new analysts who want to learn the basics of requirements elicitation and documentation. Given that poor requirements are a (if the not the) most common reason cited for project failure this article should be is fundamental knowledge for all project managers and analysts.

And it's a nice refresher for more experienced project workers also.
