Best Practices for Managing Tech Debt in Agile Development

As a software developer, it's inevitable that you'll run into tech debt at some point in your career. No matter how well you plan your development cycle, unforeseen bugs and issues are bound to crop up. And while it can be tempting to just "hack" your way through them to meet your sprint deadlines, that approach can lead to larger issues in the long run. This is why a smart developer always has a plan for managing tech debt in agile development.

So, what exactly is tech debt? In simple terms, it's the result of shortcuts taken during the software development process. These shortcuts can range from avoiding writing unit tests to using libraries with known security vulnerabilities.

But what makes tech debt dangerous is that, much like financial debt, it can quickly accumulate to the point where it becomes nearly impossible to pay back. As more code is built upon existing code, each new feature has the potential to make the underlying code more brittle and unstable. Eventually, the sheer number of shortcuts taken and bugs introduced can create a mountain of debt that's almost impossible to scale.

In this article, we'll delve into best practices for managing tech debt in agile development. If you've been experiencing code rot or an overwhelming sense of technical debt, then read on to learn how you can tackle this common problem.

Prioritize refactoring

One of the easiest ways to prevent tech debt from accumulating is by prioritizing refactoring. This means taking the time to go back through your code and clean up any "smelly" areas you find. By taking a proactive approach to removing code smells, you can prevent further tech debt from building up.

When it comes to refactoring, there are a few key things to keep in mind. First, tackle the areas that need it most. Refactoring an entire codebase can feel overwhelming, so start by identifying the areas that are causing the most problems. This could mean starting with the areas that have the most bugs or the areas that are most critical to the success of the product.

Second, refactor incrementally. Don't try to take on too much at once. Instead, break up your refactoring efforts into smaller chunks that can be tackled over several sprints. This way, you can continue to make progress while still delivering new features.

Finally, make sure you're writing tests as you refactor. Ideally, each time you refactor, you should also be adding tests to ensure that the changes you're making didn't break anything.

Use automated testing

Speaking of tests, automated testing is another powerful tool for managing tech debt in agile development. By writing automated tests, you can catch bugs and errors before they make it into production. This means less time spent fixing problems after the fact, which in turn reduces the amount of tech debt that's created.

There are a few types of automated tests you should be writing, including unit tests, integration tests, and acceptance tests. Each type of test serves a different purpose, but together, they can help ensure that your code is functioning as intended.

One key benefit of automated testing is that it can help you catch regression bugs. A regression bug is a bug that's introduced by a change in code that was previously working. These bugs can be difficult to catch, especially as the codebase grows, but automated tests can help you catch them early and prevent them from wreaking havoc.

Avoid taking shortcuts

As tempting as it may be to take a shortcut in order to meet a sprint deadline, this approach can end up costing you more in the long run. Whenever you take a shortcut, you're essentially accruing more tech debt. And if you don't pay off that debt by cleaning up the underlying code, it will continue to accumulate until it becomes a significant problem.

When faced with a sprint deadline, it's important to resist the urge to take shortcuts. Instead, focus on delivering high-quality code that's been thoroughly tested. If you find that you're consistently struggling to meet sprint deadlines, it may be time to reevaluate your development process and see if there are any inefficiencies you can eliminate.

Collaborate across teams

Tech debt is not just an issue for individual developers. It's an issue that affects entire teams and even entire organizations. This is why it's important to collaborate across teams to effectively manage tech debt.

If you're working on a large codebase with multiple teams, it's likely that different areas of the codebase will have varying levels of tech debt. By collaborating across teams, you can identify areas that are particularly problematic and work together to develop a plan for addressing them.

Collaboration can also help ensure that everyone is on the same page when it comes to technical debt. This means that there are no surprises when a particularly nasty bug crops up, and everyone understands the steps that need to be taken to address it.

Manage expectations with stakeholders

Managing technical debt is not just a technical issue. It's also a business issue. This is why it's important to manage expectations with stakeholders when it comes to managing technical debt.

Stakeholders may be focused on delivering new features as quickly as possible, but they may not fully appreciate the negative impact that technical debt can have on the product over time. By communicating the risks of technical debt and the need to prioritize refactoring and automated testing, you can help stakeholders understand the importance of taking a proactive approach to managing technical debt.

Conclusion

Managing tech debt is an ongoing process. It requires developers to be proactive in identifying areas that need attention and taking steps to address them. By prioritizing refactoring, using automated testing, avoiding shortcuts, collaborating across teams, and managing expectations with stakeholders, you can effectively manage tech debt and ensure that your code remains stable and scalable over time.

So if you're feeling overwhelmed by tech debt, don't despair. By following these best practices and staying vigilant, you can effectively manage tech debt in agile development and keep your codebase in great shape.
