In software development, technical debt is like credit card debt—if you don’t manage it properly, it can spiral out of control, leading to costly consequences down the line. Over my years as a developer and Director of Engineering, I’ve experienced the pain points of tech debt firsthand, and I’ve also learned how to effectively manage it.
This post breaks down some real-world strategies for handling technical debt without sacrificing the growth and success of your projects. Let’s dive in.
What is Technical Debt?
To put it simply, technical debt is the future cost of short-term decisions made to speed up development. Whether it’s skipping unit tests or cutting corners on refactoring, those “temporary” fixes eventually catch up, slowing down the development process and increasing maintenance costs.
We’ve all been there—you’re up against a deadline, so you push forward, promising to fix the messy code later. But “later” keeps getting pushed back, and before you know it, the debt is stacking up, dragging down performance, scalability, and developer morale.
Why Should You Care?
If technical debt isn’t addressed, it snowballs. It’s not just about cleaning up code—it’s about ensuring the future scalability and efficiency of your entire system. Companies like Twitter and Slack have faced massive slowdowns in releasing new features due to accumulating debt.
Case Study: Twitter
In the early days, Twitter’s team was so focused on keeping the platform running that they postponed critical architecture decisions. As their user base exploded, that technical debt became a major bottleneck. Twitter had to pause development for several months to rewrite significant portions of their infrastructure just to catch up, which delayed new feature releases and impacted user experience.
Proven Strategies for Managing Technical Debt
Now that we know how critical it is to address tech debt, here are the strategies I’ve found most effective for managing it:
1. Prioritize Tech Debt as Part of Your Backlog
Integrating tech debt into your regular sprint planning ensures it doesn’t fall by the wayside. Create a “Tech Debt” section in your backlog and regularly assess the severity and impact of each item. Is the debt affecting performance? User experience? Developer efficiency? Prioritize accordingly.
Tip: At Slack, they balance technical debt with new feature development by allocating 20% of every sprint purely for debt cleanup.
2. Refactor as You Go
Refactoring doesn’t need to be a massive project. Encourage your team to clean up code as they work on new features. This “Boy Scout Rule” ensures that developers leave the codebase better than they found it, avoiding massive refactor projects down the road.
In my own projects, I’ve found that small, consistent improvements often prevent the need for larger overhauls later on.
3. Create a Culture of Code Reviews
Code reviews are one of the best ways to spot and address technical debt early. By creating a culture of continuous code review, teams can identify potential debt issues as code is being written, rather than waiting for problems to emerge after deployment.
Tip: Implement peer code reviews using tools like GitHub’s pull request system to ensure that tech debt is flagged and discussed regularly.
4. Track and Measure Tech Debt
Treat tech debt like any other metric. Track it, measure it, and make it part of your development KPIs. Amazon, for example, has teams dedicated to tracking the performance implications of technical debt and allocating resources to tackle it as part of their continuous improvement.
At trakrSuite, we’ve started tracking tech debt across our projects by tagging areas that need attention during development. This simple strategy has helped us stay on top of debt and address it before it grows out of control.
5. Don’t Fear the Rewrite
Sometimes, the only solution is to bite the bullet and rewrite. I’ve had to make that tough decision before—pausing new feature development to clean up years of accumulated debt. While it can be painful in the short term, the long-term benefits are worth it.
Just look at Twitter’s architecture rewrite or Slack’s switch to more scalable infrastructure. Both companies saw huge performance improvements after tackling their debt head-on.
When to Address Tech Debt
Not all technical debt is bad or needs immediate attention. It’s about balancing the urgency of delivery with long-term maintainability. The key is to recognize when that debt starts affecting user experience, developer efficiency, or overall scalability. That’s when it’s time to take action.
Wrapping Up: Stay Ahead of the Game
In today’s fast-paced development environment, technical debt is inevitable. The trick is to stay ahead of it. Incorporate debt management into your daily workflows, make refactoring part of your culture, and keep an eye on the bigger picture.
At Jay’s Tech Bites, I continue to share insights into strategies like these, drawn from real-world experiences across my projects. Whether you’re a seasoned developer or a team lead, staying mindful of technical debt will ensure your codebase remains clean, scalable, and ready for future growth.
Final Thoughts
Technical debt can feel overwhelming, but the right strategies can make all the difference. By prioritizing debt, refactoring as you go, and fostering a culture of code reviews, you can stay on top of the chaos and maintain a scalable, efficient codebase.
