Story decomposition breaks down information from goals to a lower level.
Story decomposition allows people to look at breath over depth. What that means is that it enables a business analyst to work on the goals and break it down into the objectives and then further break it down into user stories and the acceptance criteria.
The key elements of story decomposition are
- Solution or product goals
- Minimal marketable components meaning what’s the minimal component needed in order to satisfy the goal
- User Story or use cases
- Acceptance criteria which provides the lowest level of detail
Story decomposition could end up being a wasteful activity if it us performed earlier on in the project. Therefore sometimes people have a tendency to revert back the old ways of gathering the information The timing is important and when the analysis is conducted using this technique is important.
