As software engineers, we all know the importance of writing high-quality code and building reliable software. However, the reality is that we often have to make trade-offs between perfect code and getting things done quickly. This is where technical debt comes in! The concept of taking shortcuts or adopting quick fixes that may have to be paid off later. Of course, they payback is with increased costs, greater effort, or even lower quality overall. But figuring out how to balance technical debt is something that isn’t trivial for many teams to figure out!
Over time, technical debt can accumulate and have a significant impact on software development projects. As a result, managing and figuring out how to balance technical debt effectively is crucial for project success. We need to have a strategy in place that ensures we are not ignoring technical debt but also not getting bogged down by it. By striking a balance between technical debt and productivity, we can achieve sustainable software development.
So, let’s explore how to tackle technical debt before it tackles us!
Understanding Technical Debt
Technical debt refers to a set of design or development shortcuts taken during software development. This often requires future cleanup or refactoring for the continued health and stability of the system. These shortcuts may be taken to save time or money, to meet an urgent deadline, or simply because they were the best known option at the time.
As a software project moves forward, technical debt can accumulate, and the amount of debt can build up to the point where the amount of time required to fix issues and update the code is greater than the time that was initially saved by taking the shortcuts. This buildup can cause serious problems, making it harder to develop new features, slower to fix bugs, and damaging the overall quality of the software.
What Does Technical Debt Look Like?
Technical debt can come in many forms; some examples include taking shortcuts in coding standards, delaying unit testing, skipping documentation, or deferring refactoring. The nature of the technical debt will often depend on the requirements of the project, the amount of development time and budget available, and the priorities of team members.
Despite its drawbacks, technical debt can be advantageous in certain situations. Technical debt can help create breathing room during development, allowing developers to pivot to new features or ideas rapidly. Additionally, technical debt can help an organization prioritize features and ensure that they launch features to market quickly.
To identify technical debt, software teams should frequently review their processes and code to determine areas that require improvement. These reviews can be conducted during code review, sprint retrospectives, or other forms of debugging and testing.
Overall, understanding technical debt is critical for any software developer or engineer hoping to build sustainable, scalable systems. By taking a pragmatic and reflective approach to identifying, assessing, and cleaning up technical debt, teams can ensure that their codebase remains efficient, reliable, and valuable.

How To Balance Technical Debt
Balancing technical debt is a critical factor when it comes to software development. It’s how we manage technical debt in a way that allows you to maintain a balance between innovation and maintenance. The goal is to balance maintenance, time to market, and risk such that we don’t compromise the quality of software.
Prioritizing Technical Debt
Prioritizing technical debt is a key step in balancing it. Prioritization ensures that you are working on the most critical technical debt items first. This helps you manage risk and avoid more significant problems down the line. Prioritizing technical debt should involve examining the impact on both business and technical metrics. Prioritization approaches include:
Business impact prioritization: prioritizing technical debt based on how it impacts the overall business goals.
Urgency prioritization: prioritizing technical debt based on how quickly it needs to be addressed.
Risk-based prioritization: prioritizing technical debt based on the level of risk posed to the product or team.
Factors to consider when prioritizing technical debt include the severity of the issue, the level of technical debt, and the impact it has on your team’s productivity and the product’s overall quality.
Strategies for How To Balance Technical Debt
There are several strategies for balancing technical debt. These strategies include:
Technical debt reduction: paying down technical debt through refactoring and rebuilding components that are causing the most issues.
Continuous refactoring: ensuring that technical debt is always being addressed through ongoing refactoring work.
Choosing the right technologies: selecting new technologies that will allow for reduced technical debt over the long term.
Best practices for balancing technical debt: implementing proven technical practices that help to balance technical debt like code reviews, test-driven development, and documentation.
By using these strategies, software teams can ensure that they keep technical debt under control. They can also maintain a focus on innovation and the development of new features. By successfully balancing technical debt in this way, you can develop software that remains of high quality and meets the needs of your users.

Great article on an important issue that isn't talked about as much as it should be. I've seen the dangers of technical debt quickly get out of control from continuing to use very old APIs and not migrating to newer versions (i.e., “if it ain't broke, why change it?”). Over time, continuing to use these older APIs forces developers to use older compilers because you can't link the code with newer versions of the libraries. And just as bad, in some cases you may be forced to use older versions of the operating system which even the vendor may have stopped supporting. In some extreme cases, it can even result in having to keep older hardware running. If this isn't bad enough, you also have to think about churn in the development team. Getting new developers up to speed on some old tech and the little tricks used to keep things working is not very appealing and takes extra time which means more cost. It also results in less flexibility for the devs to move around on different projects. Then consider the maintenance cycle which again will have extra costs for the same reasons. All this is a risk to the business. If a production issue is experienced, resolution can be a nightmare with some poor soul being put into the limelight to lead the fix as the business starts making the demands for immediate resolution. Whilst all this sounds a bit extreme, I have seen this happen on a number of occasions in various organizations over the years.
