This new book and its accompanying Change Planning Toolkit™ are designed to make change less overwhelming, more human and to help get everyone literally all on the same page for change.
The underlying process often motivates artifact choice. On the home page I indicate that AM is used in conjunction with another software process, such as eXtreme Programming (XP) or the Unified Process (UP), whose scope is the full lifecycle. Very often the underlying process will prefer certain primary requirements artifact(s), in the case of XP user stories and for the UP use cases, an issue that you must consider when requirements modeling. See the articles AM and XP and AM and UP for further details.
Developers are responsible for estimating the effort required to implement the requirements which they will work on. Although you may fear that developers don't have the requisite estimating skills, and this is often true at first, the fact is that it doesn't take long for people to get pretty good at estimating when they know that they're going to have to live up to those estimates. For more information, read Agile Change Requirements Management.
Developer TDD . With developer TDD you write a single developer test, sometimes inaccurately referred to as a unit test, and then just enough production code to fulfill that test. The goal of developer TDD is to specify a detailed, executable design for your solution on a JIT basis. Developer TDD is often simply called TDD.
In Tim’s case, we changed his diet and used glue-on boots for 6 months to protect his soles, and when they came off I used the Hoof Armor. He was on a super abrasive surface, so his feet wore down fast and we’d put him back in glue-ons after 5 to 8 weeks. If he’d been on a normal footing they might have stayed good longer… I don’t know.
A usage scenario describes a single path of logic through one or more use cases or user stories. A use-case scenario could represent the basic course of action, the happy path, through a single use case, a combination of portions of the happy path replaced by the steps of one or more alternate paths through a single use case, or a path spanning several use cases or user stories.
The greatest challenge with adopting ATDD is lack of skills amongst existing requirements practitioners, yet another reason to promote generalizing specialists within your organization over narrowly focused specialists.
A use case is a sequence of actions that provide a measurable value to an actor. An essential use-case is a simplified, abstract, generalized use case that captures the intentions of a user in a technology and implementation independent manner.
Agile software development teams embrace change, accepting the idea that requirements will evolve throughout a project. Agilists understand that because requirements evolve over time that any early investment in detailed documentation will only be wasted. Instead agilists will do just enough initial modeling to identify their project scope and develop a high-level schedule and estimate that's all you really need early in a project, so that's all you should do. During development they will model storm in a just-in-time manner to explore each requirement in the necessary detail.
