We mentioned the creation of personas in our overview of the interaction design process. In this post we will talk in more detail about how to create them. We will cover identification and prioritization of the personas, defining the corporate and personal goals for the personas, and creating the anecdotal stories that give each persona an identity against which we can make design decisions. Scenarios are also defined for the primary personas, which drive the creation of the functional requirements specification.

Interaction Design Process Overview
Interaction design, as described by Alan Cooper in The Inmates are Running the Asylum, is a process for designing software by focusing on the most important users. Unlike traditional requirements gathering and solution design processes, interaction design focuses on the goals of a specific class of users, represented as a persona. Those goals are considered when defining scenarios that represent how the primary persona will use the software. The combination of goals and scenarios leads to design artifacts and a functional specification. We will explore these steps in more detail in this post.

Interaction design explained by Alan Cooper
There’s a Clash of the Titans joint-interview posted at FTPOnline between Kent Beck and Alan Cooper called Extreme Programming vs. Interaction Design. It’s 10 pages of back and forth. In short, these icons agree on objectives, and disagree on how to achieve them. They also spend some time (mis)characterizing each other’s positions and defining their own. In this post we will look at how Alan Cooper explains Interaction Design. We would say that he defines interaction design more as a requirements than a design activity.

Prioritizing Software Requirements – Kano Take Two
In our previous post on Kano requirements classification, we introduced the concepts and showed how to apply them. One of our readers commented privately that we didn’t show how to use the techniques for prioritization. We’ll do that in this post.

Prioritizing Software Requirements With Kano Analysis
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:
