Technical debt is an inevitable issue in any software project. However, if not managed properly, it can become a bottleneck that hurts productivity, increases costs, and affects the scalability of the product. So how can you avoid it without slowing down delivery speed?
In this article, I’ll share best practices to minimize technical debt while maintaining a balance between speed and quality in software development.
Why Does Technical Debt Happen?
When developing products, companies often prioritize speed to market over code quality. This trade-off creates technical debt, which must be “paid off” in the future.
Just like credit card interest, the extra burden added to a project due to these decisions comes in the form of rework—teams will have to spend more time fixing software issues and implementing new updates.
It’s important to highlight that technical debt usually doesn’t stem from developers’ lack of skill but rather from poor decision-making. If this pattern is recurring in a company, it’s a red flag that teams need to reassess how they’re managing priorities in their projects.
Identifying Signs of Technical Debt
Being able to identify signs of technical debt in software projects is crucial. These signs indicate potential underlying technical issues in the code and development process. Recognizing them early helps take corrective measures before they cause significant damage.
Here are some indicators to watch for:
Recurring Delivery Delays
One of the clearest signs of technical debt is frequent delays in software deliveries. When deadlines keep getting pushed back, it might mean that the codebase is becoming too complex to maintain or that unresolved technical issues are slowing down progress.
Delays can also happen due to poor code quality. If developers spend more time fixing bugs than expected, project timelines suffer, which can lead to client dissatisfaction and increased long-term costs.
Complex, Hard-to-Maintain Code
Excessive complexity in the code is another indicator of technical debt. If the code is hard to understand, maintain, and modify, that’s a red flag.
Complexity often results from shortcuts taken during development, such as a lack of proper abstraction or the use of non-standard code structures. As complexity increases, the chances of introducing new bugs and struggling to fix them also rise.
Moreover, complex code makes it harder to integrate new features, slowing down development and increasing error risk.
Lack of Documentation or Outdated Documentation
Documentation is crucial for understanding and maintaining software. When there’s a lack of documentation or existing documentation is outdated, that’s another sign of technical debt.
Without proper documentation, team members struggle to understand how the software works and how its different parts interact. This can lead to errors during maintenance and make onboarding new team members more difficult.
Outdated documentation is equally problematic. As software evolves, documentation must be updated accordingly. When it isn’t, teams risk making decisions based on obsolete information, leading to technical issues.
Insufficient or Ineffective Testing
A lack of proper testing or ineffective tests is a critical indicator of technical debt. Poor testing can allow problems to go undetected until they become serious issues.
Effective testing ensures that the software functions as expected and that changes don’t break existing functionality. Without sufficient tests, teams risk deploying buggy code, which leads to rework and additional costs.
It’s worth noting that these indicators are often interconnected. Complex code can make writing effective tests harder, and a lack of documentation can impact test quality. That’s why addressing technical debt requires a holistic approach.
How to Avoid Technical Debt
Although it might seem challenging, it is possible to mitigate the effects of technical debt in tech companies and build higher-quality, scalable code.
If you’re looking for ways to prevent technical debt in your product, you’re in the right place. Check out these strategies!
Invest in Testing and Standardization
Testing code whenever possible is one of the best ways to prevent technical debt. It helps teams identify issues early in development, minimizing the impact of poorly written, error-prone code down the road.
Unfortunately, many developers and tech leaders still underestimate the power of testing, rushing to launch software and ending up with massive technical debt.
One way to optimize testing time is through automation. Automated tests not only speed up the process but also reduce the risk of errors with the help of quality analysis tools. This approach ensures that even remote teams can maintain high-quality standards and avoid costly mistakes.

Conduct Regular Code Reviews
Code review isn’t just a formality—it’s an essential process for maintaining healthy, sustainable software. When done correctly, it prevents problems from becoming roadblocks and reduces technical debt in the long run.
Here are some key points for an effective code review:
- Clear and consistent code: Ensure the code follows team standards and is easy to understand. Confusing code today becomes a maintenance headache tomorrow.
- Logic and architecture validation: Look beyond surface-level issues. Check whether the implementation solves the problem efficiently and aligns with the system architecture.
- Test coverage: Code without tests can break silently in the future. Always ensure that changes are adequately covered by tests.
- Frequent and small reviews: Large code reviews are inefficient and prone to errors. Prioritize smaller, more frequent reviews.
- Agile process: Pull requests that sit idle for too long create bottlenecks. A continuous review flow keeps teams productive and reduces rework.

Adopt Pair Programming
Pair programming might seem odd at first, but it’s one of the most effective ways to prevent technical debt. When two developers work on the same code together, mistakes are caught earlier, and knowledge is shared naturally.
- Reduces errors early in development: Having another person reviewing code in real-time improves quality.
- Encourages knowledge sharing: Less experienced developers learn faster from senior colleagues.
- Promotes code consistency: With two people involved, the codebase stays more standardized.
Track the Right Metrics
Monitoring metrics is essential to understand if your team is on the right track or if technical debt is piling up. Some key metrics to track:
- Lead Time
- Cycle Time
- Deployment Frequency

Conclusion
By applying these strategies, you’ll find it much easier to prevent and reduce technical debt in your projects and tech team. The key is acting fast—when teams proactively tackle this issue, they avoid “paying off” technical debt in painful installments.
After all, you’ve got enough on your plate with credit card bills—you don’t need your codebase adding to the burden!
