A platform succeeds through explicit roles and handoffs. Shared work does not mean shared accountability is undefined.
Name the actors
Different outcomes require different owners
The platform owner manages the reusable product. The application owner remains accountable for the business outcome. Engineers implement and verify. Operations coordinates service health and recovery. Governance authorities make decisions within their mandate.
A provider operates contracted capabilities but does not become the owner of TDE's application purpose.
Design collaboration
A handoff needs information and acceptance
Telling another team that a system is ready does not make it operationally ready. The receiving team needs ownership, dependencies, monitoring, escalation, recovery, and known-risk information.
Strong handoffs specify what is transferred, what remains, who accepts it, and how gaps are resolved.
- Named sender and receiver
- Required evidence
- Acceptance criteria
- Unresolved risk and follow-up
Human accountability
Automation can perform work without owning the decision
Managed services, deployment automation, and AI agents can perform substantial tasks. They do not become accountable authorities.
A named person must retain intent, review the work, verify results, and route decisions that exceed their authority.
The Ember lens
Ember Developer Qualification is intended to prepare people for platform responsibility. It does not transfer application ownership or decision authority to the platform.
Responsibility remains
Every material outcome, exception, release, and risk needs a named accountable human or authorized group.
Apply it
Clarify a real handoff
Choose a recurring platform interaction and identify who does, verifies, accepts, and supports it.
- 01Name the outcome
- 02Assign each role
- 03Identify the evidence exchanged
- 04Resolve any unowned decision
Check your understanding
Make the ideas usable
