We’ve talked before about three ways to prioritize software requirements. We’ve also talked about incorporating risk analysis into ROI calculations for requirements. In this post we will look at how Kano analysis can be applied to prioritizing requirements.

Software Requirements Specification Iteration and Prototyping
Developing great software requirements demands iteration
In our previous post of an example of the software development process, we showed a linear flow through the process, as depicted in several posts over a couple weeks. What we failed to show was any of the iteration cycles, as Deepak points out by asking a great question in the comments on that post. In this post, we will show a little more about how the process works by showing how iteration fits into the machinery of software development.

Software development process example
We’ve presented an example of the software development process across several posts over the last two weeks. In this post we tie them all together, showing the steps in process order.

Jargon gone amuck!
This video showing the abuse of jargon (2 minutes) is absolutely hysterical, and should be watched for humor alone. However, it also drives the point home about the effects of using jargon when writing requirements. When we write a PRD or SRS if we use the jargon of one domain, […]

Writing Requirements Unambiguously
Writing requirements without ambiguity
This is one of the harder parts of writing good requirements. Marcus tells us to avoid it with a good example here. Jerry Aubin at Seilevel has written an outstanding post on the subject, The art and science of disambiguation. Jerry starts his post with a gripping example from Weinberg and Gause:

Software Requirements – Process and Roles
Our previous post, Requirements vs design – which is which and why, describes our position on which parts of the software development process are requirements-activities, and which parts are design activities. The debate among professionals about these distinctions is ongoing, and continues in the comments on that post. The length of the debate, combined with the skills of those debating demonstrates that it isn’t a black and white issue.
In this post, we will try and explore the reasons why this debate is ongoing. We will do that by exploring the symbolism of the terms involved, as well as the roles of different members of the software development team.

Requirements vs Design – Which is Which and Why?
A classic debate. It comes up often. Unfortunately, it’s a source of confusion that causes many teams to shy away from staffing, creating, or managing any formal requirements processes. There’s a discussion on Seilevel’s forum where this has been brought up again, and it’s shaping up to be a fine grudge match here in Austin. We can’t let the other folks have all the fun, so we’ll chime in too.

Writing Functional Requirements to Support Use Cases
Background:
In our previous post, Sample use case examples, we created two informal use cases. The use cases were written to support product requirements defined as part of a project to reduce test suite maintenace costs. In this post, we will define functional requirements that support these use cases. This process is an example of using structured requirements, applied to a small real world project.

Sample Use Case Examples
We talked about informal use cases a while ago in our use case series. Over a series of posts, we are demonstrating the process of defining a software product. The next step, and subject of this post, is the creation of informal use cases to support the defined goals for the software.
