With a definition of the important use cases for our agile project, we can move to the logical next step – which is what exactly? Prototyping.

APR: Prioritizing Use Cases – Vote Three Times
In our agile project case study we defined corporate goals and user personas, and from our understanding created a list of use case names. We refined those use cases into use case briefs, filtering out some of the use cases (for the first revision) narrowing the list to six use […]

APR: Use Case Briefs
Each of the use cases defined as part of our use case names post is described at a high level of detail here. The goal is to get a broad view of the domain for our project so that we can focus on the most important elements. This is a […]

APR: Use Case Names
In our agile programming case study, we have two corporate goals, but one of them (learn Ruby on Rails) only drives constraints, not requirements. The other goal is to make it easier for people to find and read great content in our niche. This makes the documentation of goal-driven use […]

APR: Scope and Vision – Vote On It
In the discussion on our article about understanding users as part of our agile software development case study, Rolf raised an interesting question about the scope and vision of having people rate articles: I’m wondering what an ‘article’ is. Does it have characteristics? Is it just some piece of knowledge […]

Agile Software Development Experiment
We’re considering trying an experiment in agile software development at Tyner Blain. There aren’t (m)any examples of agile software development that we can watch and study that include agile requirements development. Many people still think that agility and requirements management are mutually exclusive. If the responses to this post don’t […]

The Difference Between Use Cases and Test Cases
People who are new to software, requirements, or testing often ask “What’s the difference between a use case and a test case?” This article answers that question, by building on earlier articles about use cases and use case scenarios. At the soundbite level, each use case has one or more scenarios, and each use case scenario would lead to the creation of one or more test cases.

What Are Use Case Scenarios?
It is easy to mix up the definitions of use case and use case scenario. A use case represents the actions that are required to enable or abandon a goal. A use case has multiple “paths” that can be taken by any user at any one time. A use case scenario is a single path through the use case. This article provides an example use case and some diagrams to help visualize the concept.

Sample Use Case Example
Here’s an example of a use case that has some system complexity. The user interacts with the main system that we are describing. The system also interacts with two external systems. This use case example shows how to describe the steps that demonstrate all interactions with the system.
