Required inputs
- Decision context and primary alternatives
- Available architecture, operating and economic information
- Interviews with accountable leaders and technical stakeholders
Fixed-scope engagement
A 10-business-day independent review of an architecture, platform, vendor, cloud, AI or build-versus-buy decision before approval or contract signature.
Outcome
A written recommendation with evaluated options, cost and operating assumptions, technical limits, decision conditions and a 90-day action plan.

A decision review compares the real options against the same constraints and keeps rejected alternatives in the record.
Decision questions
What decision must leadership approve, and what is outside its scope?
What does each option require from architecture, operations, security and people?
Which claims are supported by evidence, and which remain assumptions?
What conditions and controls are required before proceeding?
Deliverables

Options, trade-offs, risks and cost assumptions

Scope boundaries
Completion criteria
Leadership has an approved decision record; engineering teams have the constraints, owners and next actions required to proceed.
Fit
The choice is expensive or difficult to reverse.
Internal stakeholders recommend different options.
A vendor proposal is progressing without agreed evaluation criteria.
Leadership requires a documented technical recommendation.
Process
Agree the decision, stakeholders, inputs, exclusions and deadline.
Review documents, interview accountable people and test relevant technical claims.
Compare options, findings, dependencies, cost assumptions and implementation constraints.
Present the recommendation, actions, owners, open decisions and acceptance criteria.
