Exploring Extreme Programming
How do you handle delivery of new features or new systems? The easiest way is to just add the new features or replace the existing system, with no transition, but this is not the only approach. We’ll consider several strategies Continue reading Delivery Strategies
Rather than focusing on “splitting” a story, figure out a minimal form of a story, and intensify it – make it more powerful or desirable. We’ll explore one dimension, prediction: how can we make a story better by improving how the Continue reading Intensifying Stories Through Prediction
We implement feature by feature, seeking value; adding up the value forms an S curve with characteristic regions. Can we overcome the tendency of products to fade away?
T is for Testable in the INVEST model. A testable story is one for which, given any inputs, we can agree on the expected system behavior and/or outputs.
French translationS is for Small in the INVEST acronym. I now use another S that I think captures the idea even better: Scalable. Scalable means “able to be changed in size or scale,” and that’s handy in a story: We Continue reading Small – Scalable – Stories in the INVEST Model
“Intensifying stories” is an attempt to identify what can make a story (feature, capability) more potent. I’ve identified key features in a number of systems (perhaps 50), identified a rule or concept beneath those features, then generalized that to apply to Continue reading Intensifying Stories Job Aid
For a given story headline, many interpretations are possible. These vary in their quality and sophistication. I call this the intensity or depth of a story. Story intensity is a knob you can control, dialing it down for earlier delivery, Continue reading Intensifying Stories: Running with the Winners
[French translation] Of all the attributes of the INVEST model, “Valuable” is the easiest one to, well, value. Who is against value? We’ll look at these key aspects: What is value? The importance of external impact Value for whom? What Continue reading Valuable Stories in the INVEST Model
French Translation In the INVEST model for user stories, N is for Negotiable (and Negotiated). Negotiable hints at several important things about stories: The importance of collaboration Evolutionary design Response to change Collaboration Why do firms exist? Why isn’t everything Continue reading Negotiable Stories in the INVEST Model
French translation The INVEST model is a reminder of the important characteristics of user stories, and it starts with I for Independent. Independent stories each describe different aspects of a system’s capabilities. They are easier to work with because each Continue reading Independent Stories in the INVEST Model
