Technical debt is a common but often unnoticed challenge, especially for companies that rely on custom software. It quietly accumulates in the background, embedded in code or frameworks, and is not always exposed until it begins to create performance or maintenance issues. Suboptimal coding practices, poor architectural decisions, and outdated frameworks introduced to meet deadlines or rapidly deploy features can accumulate over time, leading to long-term maintainability and performance problems.
Many companies may not even realize the extent of their technical debt until it starts to affect their ability to scale or innovate. However, proactive software teams can mitigate the risks by following best practices that reduce the long-term impact of technical debt, ensuring that systems remain sustainable and scalable.
What Is Technical Debt?
Technical debt is the cost of extra work required to fix issues that arise from various development choices when developing software. It’s a metaphor for the long-term repercussions of shortcuts in coding, much like financial debt with its accruing interest. Over time, technical debt can slow down development cycles, make systems harder to maintain, and increase the risk of bugs and performance bottlenecks.
While technical debt is almost always avoidable, at Liberty Fox Technologies, we aim to eliminate it from the outset. Our thorough and thoughtful approach ensures that we don’t introduce technical debt into your systems. And when technical debt already exists, we’re here to help remediate it, ensuring long-term sustainability and maintainability for your software.
Best Practices for Mitigating Technical Debt
Code Refactoring to Remove Code Smells
Code refactoring is an essential practice for remediating technical debt. While it’s not something done regularly, it becomes necessary when dealing with poor or outdated codebases. In some cases, refactoring may not be enough, and a complete rebuild is required to properly address the underlying issues. Refactoring is about eliminating code smells, such as duplicated logic, long methods, and overly complex conditionals, but it’s a critical path to remediation, not an ongoing process.
Simplifying methods is a prime example of refactoring. Developers can break down large, complex functions into smaller, more manageable ones, which reduces code smells and improves readability. By addressing code smells through refactoring when needed, developers ensure their code is easier to maintain in the long run.
Automated Testing
Testing is an integral part of reducing technical debt. When automated tests are implemented, they catch bugs early, reduce the need for manual testing, and provide immediate feedback when something breaks. Automated unit tests, integration tests, and end-to-end tests should be part of every development process to ensure new code doesn’t introduce new issues.
The benefit of automated testing is that it serves as a safety net, allowing developers to refactor confidently, knowing they won’t break existing functionality. In the absence of comprehensive tests, technical debt accumulates faster as bugs remain undetected.
Continuous Integration and Continuous Deployment (CI/CD) Pipelines
CI/CD pipelines play a crucial role in reducing technical debt by enabling early detection of issues. Continuous integration allows developers to merge code changes frequently into a shared repository. Each change is automatically tested, helping catch bugs before they become significant problems.
Continuous deployment ensures that any code changes that pass the testing phase are automatically deployed, reducing bottlenecks in the release cycle and allowing for quicker iterations. This prevents the accumulation of untested, unstable code that often leads to technical debt.
Maintaining a Technical Debt Backlog
Just as product features and bugs are tracked, technical debt should also be cataloged and prioritized. Maintaining a technical debt backlog allows developers and project managers to stay aware of areas that need improvement without losing sight of them.
This backlog acts as a reminder to periodically revisit and address known debt. By integrating debt repayment tasks into regular sprint cycles, teams can prevent debt from snowballing into unmanageable proportions. It’s important to treat these tasks with the same level of importance as new features or bug fixes.
Incremental Refactoring and Payoff Periods
When dealing with technical debt, it’s often unrealistic to address it all at once. Instead, teams should focus on incremental refactoring, tackling small portions of debt during each development cycle. By chipping away at debt gradually, the impact on current development is minimized, while still making progress toward a cleaner, healthier codebase.
Establishing payoff periods, or dedicated time to address technical debt, is another effective strategy. These periods should be planned into the development schedule, ensuring that refactoring and code improvements don’t get postponed indefinitely.
However, proper planning, strong architectural decisions, and comprehensive documentation go a long way in preventing these issues in the first place. By building a solid foundation from the outset, development teams can avoid many pitfalls that lead to technical debt, ensuring that the code remains scalable, maintainable, and adaptable over time.
The Role of Team Culture in Managing Technical Debt
While technical strategies are essential for managing debt, fostering a team culture that values code quality is equally important. Developers need to feel empowered to raise concerns about accumulating debt and to take the time to write clean, maintainable code from the outset.
Promoting practices like pair programming and code reviews encourages knowledge sharing and improves code quality. These collaborative efforts help to catch potential issues early before they turn into costly debt. Encouraging open communication around technical debt ensures that the team remains focused on long-term code health.
