The agile principle of Story Elaboration emphasizes a " just-in-time " approach to requirement details. When a team realizes they are over-analyzing stories that won ' t be worked on for several iterations, they are creating waste because those details may change before they are ever built. By improving story elaboration, the team moves from a broad view of the solution to a granular level only when it is necessary to support build activities. This progressive refinement ensures that the most current information and feedback are incorporated into the story ' s details, such as acceptance criteria. Mastering this technique allows the team to maintain a healthy, actionable backlog while avoiding the " analysis paralysis " associated with traditional, upfront documentation, thereby upholding the agile value of responding to change over following a rigid plan.
