Abstraction And “Requirements”

Posted on:

I don’t know how many of our readers have reached a conclusion to this debate, but we have for now. Thanks to everyone who has contributed to, enjoyed, or at least tolerated this ongoing discussion. Roger had some good comments in our previous article – we’ll try and address one of his points here. His point, I believe, is that using the word “requirements” to describe multiple levels of abstraction in the definition of a product is a bad thing.

Valuable and Functional Requirements

Roger asked some interesting questions on one of our previous posts about market and product requirements. In a couple recent articles, we presented some specific examples to clarify the semantics and language of different types of requirements. Roger asks six questions about functional and non-functional requirements in the comments on the last article. In this article, we answer them.

This is my requirements document. There are many like it, but this one is mine. My requirements document is my life. [Kubrick, with some editing]. Michael provides a comparison of requirements documentation formats seen in the wild. A good companion to our earlier piece, Michael provides some “what to expect” guidance about how different companies use the different documentation formats. Check it out.

Everyone has a perspective on what each document represents, and each person on the team has a unique perspective on what questions the document answers.

Joel Spolsky Speaks Specs

Posted on:

It seems that specs are like flossing: everybody knows they should be writing them, but nobody does.

Another for the wish I had said that list. Joel Sposky wrote a four part series on writing functional specifications in Oct 2000. Joel’s opening position is that all projects lasting more than a week, or with more than one developer, will be completed faster with specs than without them. He presents three giant reasons to use a requirements document as part of developing software

Challenging Requirements

Posted on:

The hardest long term challenge in eliciting requirements is improving our ability to do it. The hardest short term challenge in gathering requirements is getting all of them. We have a lot of techniques for gathering requirements, from interviewing to brainstorming to researching. How do we know we defined all of the requirements? Everyone who manages requirements knows the value of validating requirements. But validation leaves a blind spot as it looks backwards instead of forwards. We propose to do exactly the opposite.
