You're facing technical debt in your codebase. How do you ensure quality while refactoring?
When technical debt looms over your codebase, ensuring quality during refactoring is paramount. Here's how to tackle it effectively:
- Implement automated testing to catch regressions and ensure new changes don't break existing functionality.
- Conduct code reviews with peers to spot potential issues and maintain coding standards.
- Incrementally refactor by prioritizing the most critical parts of the codebase to prevent overwhelming your team.
How do you balance addressing technical debt and maintaining quality? Share your strategies.

-
1.Set Clear Goals: Focus on high-impact areas that will yield the greatest benefit. 2.Automate Testing: Implement unit, integration, and end-to-end tests to safeguard against regressions. 3.Use CI Pipelines: Catch issues early with continuous integration to maintain code quality. 4.Collaborate: Involve QA, product, and design teams to ensure well-rounded improvements. 5.Refactor Incrementally: Make small, focused changes to manage risk and keep morale high. 6.Clean as You Go: Update dependencies, remove deprecated code, and document changes. 7.Stay Lean: Keep the codebase flexible, minimizing future technical debt.

When dealing with technical debt, our focus is on teamwork, learning, and making steady progress. We treat refactoring as a chance to improve, not a burden. Here's how we keep quality high: We start with small wins, fixing critical areas first so it doesn’t feel overwhelming. Testing gives us confidence—automated tests let us catch issues early and build safely. Code reviews let us share insights and keep our standards strong, learning from each other as we go. Instead of seeing technical debt as a setback, we view it as an opportunity to create cleaner, better code together. It’s a step-by-step journey, but each step makes our codebase and our skills stronger.

Technical Debt Management is not a one time exercise but an ongoing exercise, it requires focus on 3 dimensions 1. Defining Strategy : Key Principles standards and guidelines and continuously updating them as technology evolves and newer versions of tech stack is available. 2. Enablement of team : on What changes needs to be done for improving and managing technical debt, Ideally by providing hands on guidance. In a simple example on how to analyse impact of JDK version upgrade and what steps need to be performed to address the impacted codebase 3. Governance : Enforcement can only come after enforcement - it is important to have automated governance controls in stage gates for CI CD to to ensure technical debt reduces with every release
-
Not to be forgotten: Use tools to automate the technical debt elimination. Rather than postponing framework upgrades until the breaking point (typically some 0-day vulnerability), investigate tools and platforms like OpenRewrite and Moderne which automate upgrades to a great extent. Across the whole enterprise. At once.
-
To manage technical debt while refactoring, start by prioritizing high-impact areas and ensure thorough testing (unit and integration) to validate functionality. Use incremental changes with code reviews to maintain quality and track improvements.
-
To ensure quality while refactoring, prioritize unit tests, refactor in small, manageable steps, and validate functionality after each change to prevent introducing new issues.

Here's a step-by-step strategic plan to achieve this: I. Preparation 1. Technical Debt Assessment 2. Define Quality Metrics 3. Assemble a Refactoring Team II. Refactoring Strategy 1. Incremental Refactoring 2. Test-Driven Development (TDD) 3. Code Reviews 4. Continuous Integration/Continuous Deployment (CI/CD) III. Quality Assurance 1. Automated Testing 2. Manual Testing 3. Code Analysis Tools 4. Quality Gates IV. Monitoring and Feedback 1. Monitoring 2. Feedback Mechanisms 3. Retrospectives By following this structured approach, we can ensure that our refactoring efforts prioritize quality, maintainability, and reliability, ultimately delivering a robust and efficient codebase.

Before you refactor, consider re-imagining. This means harnessing your skills as a software designer rather than reimplementing the existing design. The problem with technical debt is that it exists in software design too, not just in code implementation. These days refactoring is easier than ever, because the language barriers of idiomatic coding have been lifted by large language models which can generate snippets of idiomatic code. While it may be tempting to pick this now low hanging fruit (refactoring, simplified by code generation), the value of refactoring is lower than it once was. Rather than simply refactoring the code base to make coding more "maintainable", make the UI, UX, and end-to-end application performance more graceful.

To ensure quality while refactoring: Understand the Code: Fully comprehend the existing functionality and dependencies. Write Tests: Create unit and integration tests to cover current functionality. Refactor in Small Steps: Make incremental changes and test frequently. Follow Best Practices: Adhere to design patterns, coding standards, and clean code principles. Code Reviews: Involve peers for review to identify potential issues. Document Changes: Update documentation and comments to reflect modifications. Monitor Performance: Ensure no regressions in performance or functionality.

1.Comprehensive Tests::Use thorough tests to catch regressions and ensure stability. 2.Incremental Refactoring::Make small, focused changes to manage complexity and isolate issues. 3.Code Reviews::Conduct reviews to get feedback and ensure coding standards are met. 3.Static Analysis Tools::Leverage automated tools to detect code smells and enforce best practices. 4.Maintain Functionality::Verify core features are operational after each refactoring step. 5.Update Documentation ::Keep documentation current to reflect code changes for future clarity. 6.Prioritize High-Impact Areas Focus on critical sections to maximize refactoring benefits. 7.Consistent Coding Standards::Adhere to established guidelines for readability and maintainability.
