The Economic Benefit of Refactoring
Summary
This Thoughtworks article by Giles Edwards-Alexander analyzes the economic value of refactoring in software development, illustrated through an AI-assisted experimentation setting. It documents a large Rust data access layer refactor and reports a dramatic reduction in input token costs (about 83%), while highlighting process notes, limitations, and broader implications for AI-enabled development and ROI of refactoring. The piece also discusses how refactoring can improve maintainability and scalability in complex codebases.
