Rewriting From Scratch vs Incremental Improvement

Developers should consider rewriting from scratch when the current codebase is so brittle, poorly documented, or technologically obsolete that incremental improvements are impractical or too costly meets developers should adopt incremental improvement when working on complex projects where requirements may evolve, as it allows for early delivery of value, easier integration of user feedback, and reduced risk of failure compared to big-bang approaches. Here's our take.

Rewriting From Scratch

Nice Pick

Developers should consider rewriting from scratch when the current codebase is so brittle, poorly documented, or technologically obsolete that incremental improvements are impractical or too costly

Pros

  • +It is particularly useful for legacy systems with high maintenance costs, security vulnerabilities, or scalability limitations that hinder business growth
  • +Related to: refactoring, technical-debt-management

Cons

  • -Specific tradeoffs depend on your use case

Incremental Improvement

Developers should adopt incremental improvement when working on complex projects where requirements may evolve, as it allows for early delivery of value, easier integration of user feedback, and reduced risk of failure compared to big-bang approaches

Pros

  • +It is particularly useful in agile environments, continuous integration/continuous deployment (CI/CD) pipelines, and when maintaining legacy systems, as it enables manageable updates without disrupting existing functionality
  • +Related to: agile-methodology, continuous-integration

Cons

  • -Specific tradeoffs depend on your use case

The Verdict

Use Rewriting From Scratch if: You want it is particularly useful for legacy systems with high maintenance costs, security vulnerabilities, or scalability limitations that hinder business growth and can live with specific tradeoffs depend on your use case.

Use Incremental Improvement if: You prioritize it is particularly useful in agile environments, continuous integration/continuous deployment (ci/cd) pipelines, and when maintaining legacy systems, as it enables manageable updates without disrupting existing functionality over what Rewriting From Scratch offers.

🧊
The Bottom Line
Rewriting From Scratch wins

Developers should consider rewriting from scratch when the current codebase is so brittle, poorly documented, or technologically obsolete that incremental improvements are impractical or too costly
