Architecture-first planning: compare costs before you build

Start with the decision

Architecture work is useful when it resolves a concrete uncertainty: an integration, data boundary, recovery need or operating cost. A small application may need a short decision record and a prototype. More documentation is not automatically better.

Compare complete costs

For an illustrative appointment workflow, compare an existing scheduler, a rules-based integration and a custom application. Include setup, recurring vendor charges, operations, support and the cost of leaving exceptions to staff. Use agreed volumes and a stated time horizon. This example is a method, not a client result or savings estimate.

Test the risky assumption

Check API access, permissions, data quality and a representative failure before committing to the design. Record the decision, alternatives and acceptance checks. Avoid treating microservices or Kubernetes as default signs of maturity.

Measure after delivery

Compare completed work, errors, change lead time and operating cost with a dated baseline. Hours released do not automatically become cash savings. Publish a financial result only when the calculation and measurement period support it.
