To decompose product requirements into sprint-ready backlog items, break the PRD or TRD into atomic tasks that deliver demoable user value. Include measurable success criteria, map dependencies, estimate effort, and define a clear Definition of Done for each task.

An atomic task in sprint planning is a focused implementation unit that delivers demoable working software within a sprint. It is needed to prevent oversized or vague technical tasks, ensuring teams can validate value and maintain predictable delivery sequencing.

Dependency mapping and effort estimation for feature tasks require applying validation rules during Gate 7. You map task relationships, assign sizing using S/M/L/XL rules, and calculate a confidence score to decide whether the task needs human review or can proceed autonomously.

Yes, you can use this task decomposition process for validating TRD coverage before subtask creation. It applies Gate 7 validation checklists to ensure no task exceeds two weeks, dependencies are fully mapped, and testing strategies and risk mitigations are explicitly defined.

The best way to define measurable success criteria and a Definition of Done for implementation tasks is to enforce a mandatory structure. Each task must specify its deliverable, user and technical value, testing strategy, and risk mitigations to ensure complete sprint readiness.
