What it means
These value-chain activities turn requirements and designs into ready capabilities, deploy them safely, operate them, fulfill demand, and support users through controlled end-to-end flow.
Why it matters
Weak handoffs among design, acquisition, build, transition, operations, and support allow requirements, risks, configuration knowledge, and acceptance evidence to disappear.
Practical focus
- Define entry and exit criteria, required evidence, ownership, and feedback for each activity and handoff.
- Integrate security, testing, support readiness, supplier obligations, observability, and recovery into design and transition.
- Trace defects and incidents back through the chain so upstream design or build causes are corrected.
- Preserve this evidence: Retain approved definitions, decisions, operating records, exceptions, test results, and change history that show how Design, Transition, Obtain, Build, Deliver, and Support works over time.
- Exercise this failure scenario: A service enters operation without support knowledge, monitoring, rollback, or verified supplier readiness because each activity assumed another team owned them.
Common mistakes
- Using Design, Transition, Obtain, Build, Deliver, and Support as a label without defining its scope, owner, decision criteria, and expected evidence.
- Treating a diagram, policy, tool screen, or meeting as proof that Design, Transition, Obtain, Build, Deliver, and Support operates consistently in real work.
- Optimizing for a one-time review while leaving normal operating decisions, exceptions, and handoffs uncontrolled.
- Testing only the expected path and never rehearsing this failure condition: A service enters operation without support knowledge, monitoring, rollback, or verified supplier readiness because each activity assumed another team owned them.
