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:
Direct answer

Build, buy and partner are delivery models, not outcomes. Evaluate them against the same need while making retained responsibilities, dependencies and exit explicit.

Practical method

The CONTROL evaluation

Use the dimensions as questions, not default reasons to prefer a model.

  1. 01

    Control

    Which elements create strategic value and require direct control?

  2. 02

    Readiness

    What skills, assets and mobilisation time does each path require?

  3. 03

    Economics

    Count lifecycle work and retained accountability, not just price.

  4. 04

    Lock-in and exit

    Test portability, knowledge transfer and alternatives.

Worked example

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.

Limits and safeguards

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.
