Design Studio — Design governance
This studio turns the topic into an architecture exercise. Produce a recommendation that another engineer could challenge, implement, and validate. There is no credit for a list of Azure products without flows, constraints, failure behaviour, and trade-offs.

Client brief
Fabrikam is modernising a production workload in this domain: Place boundaries, policy, cost ownership, compliance evidence, and privileged access at the right scope. The workload serves internal teams and external customers, carries regulated data, and must remain supportable by a small platform team. The client has supplied incomplete requirements; part of the exercise is to state assumptions and identify questions that would materially change the recommendation.
The initial requirements are:
- The design must address enterprise hierarchy with explicit assumptions and measurable acceptance evidence.
- The design must address prevent configuration drift with explicit assumptions and measurable acceptance evidence.
- The design must address protect lifecycle operations with explicit assumptions and measurable acceptance evidence.
- The design must address govern access lifecycle with explicit assumptions and measurable acceptance evidence.
- The solution must use Microsoft Entra identities, private connectivity where justified, infrastructure as code, and observable health signals.
- The design must state a recovery path, operational owner, cost driver, and one deliberate compromise.
Candidate decision anchors
| Requirement thread | Candidate starting point | Qualification rule |
|---|---|---|
| Enterprise hierarchy | Management groups and subscriptions | Organise by durable governance differences |
| Prevent configuration drift | Azure Policy and initiatives | Audit first, then deny/modify/deploy with remediation |
| Protect lifecycle operations | Resource locks and deployment stacks | Do not confuse protection with authorization |
| Govern access lifecycle | PIM, access reviews, entitlement management | Remove standing and stale access |
These are starting points, not an answer key. You may select a different service when a stated assumption or constraint justifies it. Every deviation must identify the requirement it serves and the new operational cost it introduces.
Studio workflow
Clarify
Write five questions whose answers could change the architecture. Mark hard constraints separately from preferences.
Required submission
- A one-page architecture diagram with a text equivalent.
- A decision record containing context, decision, alternatives, consequences, and validation evidence.
- A requirement-to-control matrix that maps every hard constraint to a component or operating process.
- A failure table covering component, zone, region, identity, network, and operator-error failures where applicable.
- Three validation tests: one functional, one reliability/security, and one operational or cost test.
Review traps
- Tags do not inherit without policy.
- NotActions is not an explicit deny.
- Root-scope assignments can create exception debt.
Assessment rubric
| Dimension | 0 — Missing | 1 — Partial | 2 — Release quality |
|---|---|---|---|
| Requirements | Products chosen before constraints | Some constraints mapped | Hard constraints, assumptions, and change-driving questions are explicit |
| Architecture | Component list | Main flow shown | Identity, traffic/data, dependencies, and failure boundaries are coherent |
| Trade-offs | No alternative | Alternative named | Strongest alternative rejected using a stated requirement |
| Operability | Monitoring mentioned | Some runbook detail | Health, capacity, deployment, recovery, ownership, and cost evidence defined |
| Currency | No sources | Secondary/undated source | Current Microsoft primary source linked and reviewed date recorded |
Reflection
- Which requirement eliminated the most attractive alternative?
- Which assumption creates the greatest residual risk?
- What would you test in a pilot before approving production deployment?
- How would the recommendation change if the operations team doubled in size or the recovery objective tightened?
