One of the ten big rules of writing a good MRD is writing requirements that do not specify design. How do we specify enough detail to be actionable without constraining the engineering team? How do we trust our developers to do the right thing? The Big Rule of Avoiding Design-Agnosticism […]

Writing Concise Requirements
One of the ten big rules of writing a good MRD is writing concise requirements. We have to minimize the amount we write to avoid information overload. We also need to make sure we write enough to get the message across. How do we strike the balance?

Writing Good Requirements – The Big Ten Rules
Pragmatic Marketing has a training seminar called Requirements That Work. In support of that, they provide a list of 8 characteristics of good requirements. We change one and add two more to round it out to The Big Ten Rules. Combine this with Michael’s ten tips for writing MRDs, and we’ve got a good handle on how to create a great MRD.

Requirements Documents – One Man’s Trash
…Is another man’s treasure. There are many different ways to document requirements when developing software. And there is a proliferation of requirements documents – MRD, PRD, SRS, FRS and design documents. 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
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

Passing the Wrong Whitebox Tests
We’ve talked about the value of using whitebox testing in our Software testing series post on whitebox testing. What we haven’t explored is how to make sure we are creating the right tests. We have to validate our tests against the requirements. This post shows where the flaw is in the typical whitebox testing process, and how to fix it.
A reader emailed us with the comment, “It’s been my experience that developers can’t test their own code.” Their problem was that they were missing a link in the software development chain (missing a step in the process).

Product management success in the conceptual age
The information age is ending and the conceptual age is beginning. In A Whole New Mind, Daniel Pink proposes that six characteristics of right-brain thinking are key to success in the new economy. Nils Davis realizes that these characteristics are embodied by good product managers today. We will define the conceptual age, review the six characteristics, and see how this applies to product management.

Expert systems – do what I say, not what I should have said
We’ve studiously avoided talking about requirements for expert systems because it is such a small niche of software development. Please let us know in the comments on this post if this is an area you would like to read more about. This post is both a discussion of the main barrier to success for these systems and an introduction to future posts if you ask for them in the comments on this post. Expert systems, or AI programs can solve some of the hardest problems. Yet AI software has not dominated the software landscape, neither Heinlein’s nor Vinge’s fictions have become real. Why has AI software failed? It isn’t that the hardest problems are too hard to solve, it’s that they often don’t need to be solved at all.

Interaction Design and Structured Requirements
subtitle: Wiegers and Cooper assimilated
Wiegers promotes structured requirements. Cooper touts Interaction Design. Both have great ideas. Both “wave their hands” at parts of the process. In this post, we’ll talk about how to combine the two philosophies to get the best of both worlds.
