Software Requirements – Process and Roles

Posted on:

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?

Posted on:

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

Posted on:

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.

Software Testing Series: Organizing a Test Suite with Tags Part Two

Posted on:

This is the second in a three-part post about using tags as a means to organize an automated test suite.

Part 2 of this post can be read as a standalone article. If it were, it would be titled Top five problems with test automation suites. If you’re only reading this post and not parts 1 and 3, pretend that this is the title.

Software Testing Series: Organizing a Test Suite with Tags Part One

Posted on:

This post is a follow-up to our previous case study on incorporating unit testing into an existing team’s development environment. The case study is based on a real solution that has already started reaping rewards for our client, and is gaining momentum. We’re now looking at making it easier for the development team to maintain this test suite, and proposing some extensions – including a form of tagging.

Using ROI For Requirements Is A Risky Business

Posted on:

We’ve talked repeatedly about using ROI to drive prioritization of requirements based upon value. ROI can be used as the basis for prioritization for all decision making.

If we fail to take risk into account, our calculations will certainly be wrong, and we may make a poor decision. When we talk about accounting for risk in this context, we mean that we are accounting for the unlikely, undesired, or unintentional outcomes. We use the term expected value to refer to the risk adjusted approximation of the outcome. In financial circles, this is also called discounting.

The most common mistake people make when calculating ROI is failing to take into account the expected value of the return or the expected value of the cost of a project.

iRise – software prototyping tool

Posted on:

We received a comment from Tom Humbarger at iRise on an earlier post, which led us to take a look at their site. iRise provides a tool for rapid prototyping of web-based applications, and there’s an overview of the products available. They have iRise Studio which allows people to create […]
