Reduce Technical Debt And Prevent it From Turning Into Financial Debt

The deal seems great—you get the house you want at a lower rate, leaving more budget for decoration. But along with the house, you’re also buying the smell, which will cost you time, money, or comfort in the future.

In this article, we explore common trade-offs engineering teams face when making architectural decisions and how technical debt can quickly translate into financial debt. We also review tips for balancing development and business expectations that let you reduce technical debt.

Understanding the trade-offs of architecture design to prevent technical debt

Designing software architecture is essentially about making technical and navigating resource constraints. As a data engineering team leader, you’re likely in the middle between balancing your resources at hand and a strong deadline or budget you can’t exceed. 

The truth is, you can’t always run away from technical debt. However, you can learn to evaluate your alternatives to reduce how much time you’re borrowing from your future team.

These are factors you should keep in mind when making architectural decisions and commitments:

• The product’s deadline

• The project’s budget

• Your team’s expertise, size, and availability

• The project’s scope

• Organizational processes and internal policies or restrictions

• Security and compliance regulations

Examples of good and bad trade-offs

It’s common to hear that technical debt happens when the roadmap is too ambitious. But, the challenge isn’t in planning ambitious software; it’s in leading effectively without compromising your team’s well-being, your business’s reputation, or financial stability. 

Error

For instance, if you don’t have enough clarity about a particular aspect of the design, you can hire an IT consultant before making an unrealistic decision. Or, if you need to approach a complex topic, find a specialist to help out before agreeing to an unachievable deadline or using the wrong technology. 

What adds to your technical debt?

There are intentional and unintentional causes of technical debt, as well as legacy causes. 

If we set aside using old code or outdated systems, we can say that there are two major reasons that lead to technical debt: Lack of knowledge and high egos. 

Lack of knowledge usually leads to unintentional technical debt as some technologies will simply be out of your area of expertise. For instance, you may commit to using technology that’s new to you but seems easy to learn, or you may stick to the ones you know because you ignore if there are better solutions. 

That’s why it’s so important for you to encourage your team to learn and practice new skills as part of their personal and professional development. This includes learning about other systems, other technologies, and even other languages. “It doesn’t matter if you plan to use them or not. It’s about being aware, and maybe giving you other ideas on how to solve problems,” says Gustavo.

Encouraging continuous knowledge also allows them to take a more active part in the architecture design as they can act as your internal specialist. You can turn to them to clarify complex aspects of your design and make better decisions. 

Lack of knowledge can also lead to writing poor definitions, planning an overly ambitious roadmap causing teams to accelerate their deliveries, and using the wrong technology. 

The second major cause of technical debt is ego—this is likely to cause intentional debt. No one wants to admit that they can’t do something or that the technology they’re experts in isn’t necessary in this scenario. 

“Great engineers, and people in general, leave their ego at the door, and engage in constructive discussion with their peers to look for the best solution,” says Gustavo. This is important because people with low egos, find solutions that benefit the project, not the solution that suits them the best.

Leaders with high egos can lead to technical debt by making the wrong decisions, causing high employee rotation, sticking to old systems and technology, or making false promises to stakeholders. A high ego can also lead to team leaders committing to an aggressive deadline to satisfy the leadership team at the stake of their team’s work-life balance. 

Other intentional causes of technical debt come from everyone in the project knowing the importance of meeting a deadline or sticking to a budget. This can lead to everyone crunching for a few months or making quick fixes despite knowing they’ll need to address these mistakes in the future. 

How does technical debt affect your business finances

Technical debt can quickly turn into financial debt, that’s why it’s so important to properly assess those initial trade-offs. “You can end up running a business in which acquiring customers is more expensive than the lifetime value they provide. And, unless you have lots of money or are in a really aggressive expansion phase, you may end up burning your reserves faster than you can spell the word ‘technical debt’,” says Gustavo.

Technical debt can become a serious financial problem by causing you to:

• Pay increasingly large bills to cloud providers due to inefficient use of resources

• Experience high customer churn as a result of a buggy and unreliable tool

• Invest more money in acquiring new customers

• Hire additional staff or consultants to identify and address the root causes of your technical debt

• Neglect security and compliance, leading to potential damage to your brand reputation and fines

• Increase customer support needs to address the concerns of unsatisfied customers

• Cause your team to experience burnout, which can lead to high staff turnover

Best practices to avoid technical debt from turning into real financial debt

Although it may seem impossible to code and push solutions at a fast pace without generating technical debt, there are ways to prevent it from turning into a heavy financial problem. Here are the best practices we follow at NaNLABS and recommend to others:

1. Be transparent and practice open communication. This seems simple, but it works wonders to admit that you’re uncertain about how some things will play out and ensure the business understands the risks. This can allow you to get more experimentation time or increase the budget to hire an expert. Also, being transparent with your team about your goals and spending, allows them to make better decisions that match the overarching goals. 

2. Build your knowledge toolbox. You can’t be an expert in everything, but you can stay on top of trends and explore new technologies as you grow in your role. Encourage your team to do the same, this way, you can have a diverse and informed group that can help you make specialized decisions. 

3. Build the factory, not the toy. Build processes around you that help your team follow standard operating practices. Make sure to use processes to help you organize work without adding too many details or restrictions. This allows your team to write better documentation and follow best practices so anyone can pick up where they left it. Also, befriend automation to avoid repetitive tasks and testing. 

4. Test the important bits. Automate testing to test as much as you can. While the recommendation is to get 80% of test coverage, when time is tight, the best advice we can give you is to rigorously test the most critical parts of your system.
