1.1
Lifecycle, Agents, Workflows, and Artifacts
BMAD organizes work through specialized agents and named workflows. QA value comes from the artifact chain and review boundaries, not from agent role-play alone.
Treat each BMAD agent as a responsibility lens with a defined input and output. Product artifacts establish user and business intent. Architecture artifacts expose constraints and quality attributes. Stories make the work implementable. QA artifacts challenge risk, design coverage, and collect evidence.
The method helps keep context and sequence visible, but generated handoffs can still drift. Put stable requirement, story, risk, and test IDs in artifacts. Review every transition against the owned source rather than trusting that two agents shared the same interpretation.
| Artifact | Primary question | QA challenge |
|---|---|---|
| Product requirement | What value and behavior are needed? | Are risks, boundaries, and acceptance observable? |
| Architecture | How will the system satisfy constraints? | Are test seams and NFR evidence paths designed? |
| Story | What can be implemented now? | Are acceptance criteria traceable and independently testable? |
| Test design | What evidence addresses which risk? | Does priority match impact and likelihood? |
| Gate | Is the release evidence sufficient? | Who owns residual risk and exceptions? |
If one model generated the requirement, test, review, and gate recommendation from the same context, add independent evidence and accountable human review.
Draw the artifact chain for one current epic. Name the owner, stable ID, verifier, and approval point at every handoff.
