Incremental Refactoring vs Rewrite From Scratch
Developers should use incremental refactoring when working with legacy systems, large codebases, or in Agile environments where continuous delivery is prioritized meets developers should consider a rewrite when the existing codebase has become unmaintainable due to accumulated technical debt, uses obsolete technologies, or has architectural flaws that hinder scalability and new feature development. Here's our take.
Incremental Refactoring
Developers should use incremental refactoring when working with legacy systems, large codebases, or in Agile environments where continuous delivery is prioritized
Incremental Refactoring
Nice PickDevelopers should use incremental refactoring when working with legacy systems, large codebases, or in Agile environments where continuous delivery is prioritized
Pros
- +It reduces risk by avoiding big-bang changes, enables faster feedback loops, and helps maintain system stability during improvements
- +Related to: test-driven-development, agile-methodologies
Cons
- -Specific tradeoffs depend on your use case
Rewrite From Scratch
Developers should consider a rewrite when the existing codebase has become unmaintainable due to accumulated technical debt, uses obsolete technologies, or has architectural flaws that hinder scalability and new feature development
Pros
- +It is particularly useful for legacy systems where the original design no longer aligns with current business requirements or modern development practices, allowing for a cleaner, more efficient implementation
- +Related to: refactoring, technical-debt-management
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Incremental Refactoring if: You want it reduces risk by avoiding big-bang changes, enables faster feedback loops, and helps maintain system stability during improvements and can live with specific tradeoffs depend on your use case.
Use Rewrite From Scratch if: You prioritize it is particularly useful for legacy systems where the original design no longer aligns with current business requirements or modern development practices, allowing for a cleaner, more efficient implementation over what Incremental Refactoring offers.
