5 Steps for Effective Technical Debt Reduction
5 Steps for Effective Technical Debt Reduction
Technical debt is a common issue in software development that appears for different reasons. It can transform into a costly problem if ignored and unaddressed. To make sure it won’t happen, business and tech executives adopt smart and efficient strategies for technical debt reduction.
If you are looking for ways to understand and manage technical debt on your project, read on – this post will come in handy. We will answer major questions about tech debt and ways to reduce and avoid it.
- What is technical debt and how to identify it?
- What are the key reasons for growing technical debt and how it affects a software project?
- How to reduce existing technical debt and prevent new debt from emerging?
- Where to find help to develop an effective technical debt reduction plan?
Technical debt is the delayed development work that was set aside, often on purpose, to speed up software project delivery. Companies may decide to accumulate some technical debt to achieve certain business objectives, e.g. meet a tight deadline or roll the product out as fast as possible to outrun competitors. One of the most frequent causes of technical debt is the need to get the system out in the field to better understand how to solve a given problem and get the missing information needed to design and develop a better product.
Technical debt in software engineering often refers to choosing a good working solution over a perfect one to save time or resources. For the time being, this solution reflects current business goals and can later be polished, amended or improved.
Technical debt, however, has nothing to do with poor coding. Bad code is never an option.
Key causes of technical debt
As we mentioned before, there are many reasons why technical debt may appear. While some companies deliberately opt for some debt as a tradeoff for faster delivery, others have to deal with unintentional debt caused by changing market reality and business goals.
Design or development teams may have not enough information to find an optimal technical solution for a problem. In this case, they choose a temporary working solution to win time, gather user feedback and other insights necessary to work out a better solution or technical approach.
Changing business goals
It’s not unusual for business goals to change halfway through a software development project. This may shake up priorities, add new requirements or event modify the overall product strategy. As a result, previous technical solutions may become obsolete and create technical debt.
Technologies evolve now faster than ever before. When software modernization gets postponed for too long, it may end up with emerging and growing technical debt.
Tight deadline, limited resources
One of the key causes of technical debt is a tight project deadline that forces a development team to take shortcuts to deliver in time.
Depending on the cause of debt, it may pose different risks for a software project.
Effects and risks of technical debt
Just like financial debt, technical debt must be paid off in time and as planned (if it was intentional). Otherwise, it may build up and create a domino effect making it harder to keep track and deal with it later. Among the common risks associated with ignored or mismanaged tech debt are:
- Slower performance and the increasing difficulty to make changes and scale
- Overlapping, incompatible technologies
- Higher development and maintenance cost
- Increased number of bugs, difficulty finding solutions for new problems
- Decreased usability, security risks
The longer the debt is unaddressed, the higher the interest is – the difficulty and cost of dealing with the development work that was put off. To prevent the debt from eating up the resources that could otherwise be used to further develop the system, we recommend an effective approach to technical debt reduction.
Here are 5 essential steps to keep technical debt under control and make sure it is paid off in time and with minimum investment.
Step 1. Acknowledge and understand debt
Effective technical debt reduction strategy starts with acknowledging the debt and understanding its source. At this step, you need to figure out how the debt occurred in the first place.
Was it planned or unintentional? Was it caused by changing scope, project goals, the evolution of technologies? Could it be avoided? Answering these questions will help you understand the nature of your debt and determine how you can reduce technical debt later on.
Step 2. Evaluate and measure
Depending on the causes and effects of technical debt, you may use different factors and techniques to analyze and measure it.
Technical debt may decrease the speed of development (e.g. because of the growing code complexity), so analyzing the amount of work done from iteration to iteration may show the impact of tech debt on team performance. In other cases, teams may use analytics tools that monitor system performance to track down the problems and see how these problems correlate with the technical decisions that caused the debt.
After having the debt evaluated and measured, you can assess the risks and make the cost-benefits analysis.
Step 3. Communicate and deliver cost-benefits
Technical debt assessment is important for both tech executives and non-tech decision-makers in the organization.
First of all, because it gives better visibility and allows to communicate the problem. It often helps to put a price tag on a problem to show how it may affect the project and explain why paying a debt in time is important.
Secondly, clear cost-benefits analysis helps to better prioritize and plan the payment strategy.
Step 4. Schedule regular and frequent pay-off
How to reduce technical debt without compromising the ongoing progress? One of the most efficient strategies is to divide the scope of the extra work into smaller milestones and gradually pay it off by integrating it into the normal workflow. This approach helps the team stay on top of the technical debt and make sure it’s getting smaller over time.

Step 5. Introduce practices to minimize/avoid tech debt
This is the last step of the technical debt reduction strategy. However, we recommend introducing the practices that help minimize and avoid tech debt entirely as early as possible.
- Develop and maintain a solid testing strategy to avoid bugs or imperfections from piling up.
- Measure and monitor code quality and complexity to make sure it’s reusable and understandable.
- Keep track of the technical debt and maintain a record of all the work done to reduce the debt.
- Opt for smart requirements prioritization and an agile development approach to minimize the chance to accumulate any tech debt.
Let’s look into these practices in more detail and see how they can help you avoid technical debt entirely.
Focus on requirements prioritization
Reasonable requirements prioritization is a true way to avoid unnecessary technical debt. Using different techniques for requirements prioritization, project managers work out the scope and development strategy that reflects given business goals and timelines.
Often it means that only essential requirements get to the original scope, while the rest of the features are developed after the first version of the product is out. It allows the team to focus on well-balanced MVP development without the need to take shortcuts to meet tight deadlines.
Adhere to agile methodology
Agile software development is one of the key solutions for technical debt reduction. The idea of iterative development sits well with the incremental approach to tech debt reduction. Teams that work in an agile environment manage to keep technical debt under control by continuously reducing it, iteration by iteration.
Moreover, agile methodology provides the flexibility and testability needed to avoid technical debt in the first place.
Choose flexible and scalable architecture
Flexible microservices-based architecture helps developers create scalable software. Dividing a system into small functional components provides better stability, maintainability and security and makes it easier for engineers to support and upgrade the system. That, in turn, helps to avoid technical debt related to delayed software modernization.
Augment your development team
How to avoid technical debt which occurs due to lack of time or resources? Team augmentation is a viable strategy for companies that can’t meet tight deadlines. Instead of cutting corners to keep up with the delivery schedule, add extra talent to your in-house team and focus on achieving your business goals without risks.
