Scenario evidence
- Three teams maintain overlapping preference logic.
- Several customer-facing surfaces can change related settings.
- Semantic changes require coordination across teams.
- Cross-product meaning has no accountable owner.
Illustrative example Not a client case study
Shared notification preferences belongabove threeproduct teams.
This fictional scenario shows the format and judgment of an Executive Decision Altitude Review. The inputs are assumptions, not facts observed in a client organization.
01 Scenario input
The same rule is being interpreted in three places.
Assume three product teams store and interpret overlapping notification preferences separately. A customer can change settings through several product surfaces. A change to the meaning of a preference requires coordinated releases. No single owner is accountable for that meaning across products.
These are fictional scenario inputs. They are not observed client facts.02 Evidence boundary
State what is known. Keep the unknowns visible.
Missing evidence limits the recommendation. It does not disappear because a centralized design looks cleaner.
Evidence to obtain
- How often inconsistent behavior occurs and what it costs
- The real latency and availability requirements
- The condition and conflict rate of existing preference records
- Whether a credible owner has the authority and capacity to operate the capability
03 Recommendation
Centralize the rule. Keep product decisions local.
Move the canonical preference state and its interpretation into a shared product capability with one accountable owner. Keep message intent, content, and timing with the product teams.
Do not centralize all communication. Centralize only the rule that answers whether a communication is allowed for a customer, channel, and context.
Proceed only if the inconsistency is consequential enough to justify shared ownership and the operating requirements can be met without creating a central delivery queue.04 Capability contract
Define what moves before moving ownership.
The contract separates the stable shared need from the product work that should remain close to each team.
- Outcome
- Resolve whether a communication is allowed for a customer, channel, and context.
- Guarantees
- One authoritative state, versioned semantics, auditable changes, and service commitments based on measured consumer needs.
- Boundary
- The shared capability owns preference state and interpretation. Product teams own communication intent, content, timing, and the surrounding experience.
- Evolution
- Use a versioned contract and staged migration. Keep a reversible path until the capability satisfies the agreed consumer needs.
05 Risks and conditions
The recommendation fails if ownership becomes a bottleneck.
These are the conditions that would weaken, stop, or change the recommendation.
- 01
The shared owner becomes a delivery queue for product-specific requests.
- 02
The capability expands into message content or campaign decisions that should remain local.
- 03
Existing records conflict during migration and there is no agreed resolution rule.
- 04
Latency or availability is designed from assumption rather than observed demand.
- 05
The named owner lacks the authority or capacity to enforce the contract.
06 Sequenced next decisions
Reduce uncertainty before expanding the migration.
A recommendation becomes useful when the next decisions are explicit and ordered.
- 01
Verify the frequency and impact of inconsistent preference behavior.
- 02
Name the accountable owner and confirm the authority that comes with ownership.
- 03
Define the capability contract, consumer responsibilities, and explicit non-goals.
- 04
Choose the smallest migration slice that tests the contract with real consumers.
- 05
Define measurement and reversal criteria before expanding the migration.
07 Proof boundary
This shows the work. It does not claim a result.
This sample demonstrates the format and judgment of the review. It is not a client result, delivery history, endorsement, demand signal, or evidence that the recommendation produced a business outcome.
STS Systems That Scale
Bring one decision that has become expensive to change.
Fit is determined before scope or fee is proposed. If the problem is not specific, consequential, accessible, and suitable for the review, I will say so.
