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.

Interrelation Digraphs As Prioritization Tool

Posted on:

Prioritization can be hard, especially when we’re dealing with a lot of variables. Peter Abilla, at shmula.com takes a fairly esoteric tool (interrelation digraphs) and applies it as a prioritization tool. Opthamologists have learned that they can’t show us a bunch of blurry images and have us tell them which one looks the best, and then prescribe a corrective lense. They have to ask us “Is it better like this? Or better like this?” Peter’s approach does the same thing, but with a quantitative edge.
