Exploring Extreme Programming
Products supporting standards have an all-or-nothing flavor. After all, who wants a compiler for only half of a programming language? We’ll look at guidelines that let you develop such products incrementally. Some examples of such systems: Compilers Phone switching systems Continue reading Incremental Design with Standards-Based Products
I recall a game design challenge where your only input is a pushbutton. What if your only input is a single textfield? Let’s look at what search engines have done under this limitation. That can give us ideas for intensifying Continue reading Intensifying Stories with Limited Input
A user story is a scenario, a description of a (potential) real use of a system. It takes the customer or user perspective, and represents a team’s shared understanding of what the system should do. Because stories take a customer Continue reading What Is a User Story?
Conversations about user stories focus on the behavior of a system, without regard for time, memory, etc. Other times, we have real-world constraints – quality attributes – that may not fit comfortably as stories: performance, memory, extensibility, etc. Behaviors are Continue reading User Stories and Quality Attributes
I developed the INVEST model years ago to help someone (and then many people) think about the user stories they were creating. Is INVEST all you need to create good stories? Unfortunately, no. INVEST Briefly, INVEST (see References) is an Continue reading All You Need is INVEST? No!
When we’re creating or extending systems, there’s often one type of user that’s our main focus. We often have no trouble thinking up capabilities they need. But other types of users are often forgotten. We need to enlarge our view, Continue reading Forgotten Stories
How do you track user stories? Does it help your team work better? We’ll compare multiple different approaches. Why Track? Why do we want to track user stories? There are several reasons, some better than others. We want to: understand Continue reading 7+ Ways to Track User Stories
Some teams try to start projects directly with user stories, but many important things need to happen earlier to make those effective. Chartering (aka Liftoff) provides a better way to structure the start of a project. Beyond that, there are Continue reading Chartering and more: What happens before user stories?
Many user stories fit the model of trigger and response: the user does something, the system responds. For example, if you type a letter, the word processor inserts it; if you press the “Buy” button, the system processes your order. Continue reading Is Trigger vs Response a Good Story Split?
I’ve been involved with several projects over the last few months, and each has user stories associated with it. People often ask for examples of user stories, so I thought I’d share these. The Form By default, I use the Continue reading Examples of User Stories 2020
