ILLUSTRATIVE APPLICATION WORKFLOW

Keep an existing codebase aligned as requirements change

Use the optimization button to guide repeated refactoring of a billing application against its code and evolving abstract specs.

THE SITUATION

Start with the process and the requirements.

A billing application has accumulated duplicate pricing rules and fragile integrations. New requirements make it harder to tell which behavior is intentional.

Abstract spec

Update the abstract-spec page with current pricing rules, integration contracts, and behaviors that must not change. Identify gaps between the existing codebase and the intended application.

Development tasks

Use the optimization button to continuously refactor against both the codebase and the evolving specs. Consolidate duplicate logic, simplify dependencies, and revise tasks as each pass reveals new information.

Validation and iteration

Run regression tests and compare each change with the acceptance criteria. Work toward convergence to a marginal minimum, stopping when further passes yield only marginal improvement rather than assuming an endless loop guarantees correctness.

Practical benefit

Reduce maintenance friction while protecting required behavior. Reviewable changes and an explicit convergence target make optimization a disciplined maintenance workflow, not a one-off rewrite.
