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.

Software design and specification and making movies
Alan Cooper presents the analogy that software development is like making movies in his book, The Inmates are Running the Asylum. Cooper is presenting the analogy in the context of validating the business case for investing in interaction design, but it holds true for requirements as well.

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.
