Build vs Buy vs Partner: A Structured Solution Evaluation
Evaluate build, buy and partner paths across strategic control, capability, time, economics, dependencies and reversibility.
Published:
Build, buy and partner are delivery models, not outcomes. Evaluate them against the same need while making retained responsibilities, dependencies and exit explicit.
The CONTROL evaluation
Use the dimensions as questions, not default reasons to prefer a model.
- 01
Control
Which elements create strategic value and require direct control?
- 02
Readiness
What skills, assets and mobilisation time does each path require?
- 03
Economics
Count lifecycle work and retained accountability, not just price.
- 04
Lock-in and exit
Test portability, knowledge transfer and alternatives.
A hybrid answer
The team buys a stable platform, builds a differentiating allocation rule and uses a partner for migration. Evaluation allows a combined path rather than three exclusive labels.
What this method cannot guarantee
- Evidence and operating conditions can change; revisit the record when a material input changes.
- This method structures evidence and judgement; accountable people still make and own the final decision.
