They act as a bridge between the business side of the project and the technical side, directly settled in the management of project backlogs, prioritizing tasks, and defining user stories and requirements. Even though they are not supposed to penetrate the technical complexities deeply, being aware of the concept of technical debt is crucial for any Product Owner, especially those preparing for the Advanced Certified Scrum Product Owner (A-CSPO) exam. This article explores why Product Owners should be cautious about accumulating technical debt.
Technical Debt and Its Dangers
Technical debt, in essence, is a concept in programming that reflects the extra development work that arises when code that is easy to implement in the short run is used instead of applying the best overall solution. It is comparable to financial debt, which is often acceptable when controlled, but can be harmful when it accumulates over time.
For any Product Owner, technical debt can turn into a substantial problem for several reasons:
- Code Quality and Maintenance: High amounts of technical debt can lead to poor code quality, making the system difficult to maintain and update. When forced to work with a poorly designed system, developers might need more time to implement new features or even fix bugs, which directly affects the product’s time to market.
- Further Debt Accumulation: As the team spends more time addressing the issues caused by the debt (by means of “quick fixes”), they may end up incurring additional technical debt, leading to the snowball effect.
- Risk of System Failures: A system with a lot of technical debt is more prone to experience errors, crashes or security vulnerabilities. This can impact customer satisfaction and the overall competitiveness of the product in the market.
Techniques to Manage Technical Debt
For Product Owners, part of the role is predicting and managing the accumulation of technical debt. Here are some techniques:
- Priority of Debt Issues: Product Owners, together with the development team, should prioritize technical debt issues in the backlog – just as they would with other tasks or features.
- Regular Refactoring: This process of restructuring existing code without changing its external behavior can help in debt reduction. It allows the team to improve the nonfunctional attributes of the software, making it easier to maintain and extend over time.
- Continuous Integration and Regular Code Reviews: This practice involves integrating work frequently, leading to multiple versions of the project each day. By doing so, problems are detected and rectified immediately while encouraging more transparency and communication within the team.
- Adoption of Test-Driven Development (TDD): This approach encourages developers to write tests before writing the minimum amount of code required for the test to be passed. Therefore, it enhances the clarity and bug-free process of coding, and helps control the technical debt.
While the Product Owner is not technically responsible for writing or reviewing the code, overseeing these processes effectively and fostering a culture of quality will undoubtedly diminish the technical debt.
The Role and the Responsibility
A Product Owner who is careful about not accumulating technical debt builds a stronger, more maintainable product over time. This means happier teams and customers ultimately, making the product more competitive. Therefore, it’s imperative that the Product Owners who are preparing for the A-CSPO exam understand this thoroughly to make the best-informed decisions regarding their product.
To sum up, the management of technical debt is clearly a balancing act. While some level of ad hoc programming decisions is unavoidable in a fast-paced, Agile project environment, an excessive accumulation can have long-term consequences. By being aware and taking active steps to manage technical debt, Product Owners can ensure a smoother, more efficient project and a more robust product.

Accumulation of technical debt can lead to a faster product delivery.
- A. True
- B. False
Answer: B. False
Explanation: Instead of faster delivery, accumulated technical debt can actually slow down the development process.
Paying off technical debt should be considered as an investment by the Product Owner.
- A. True
- B. False
Answer: A. True
Explanation: Paying off technical debt reduces future costs and risks and should therefore be considered as an investment.
Ignoring technical debt can lead to codebase becoming difficult to manage.

Interview Questions
What is technical debt in the context of product development?
Technical debt refers to the extra development work that arises when a team opts for a quicker, easier solution instead of choosing a better approach that would result in a better outcome but would require more time.
Why should a Product Owner be wary of accumulating technical debt?
Accumulating technical debt can lead to slower delivery times, decreased productivity, and lower quality products. This could result in customer dissatisfaction and reduced business value.
How can technical debt impact the project’s schedule?
As technical debt accumulates, more and more time is spent on correcting past decisions and less on developing new features, effectively slowing down the project’s schedule.
What role does a product owner play in managing technical debt?
As product owners are closest to the business side and understand the business value of the product, they play a key role in prioritizing technical debt in the product backlog to ensure smooth product development.
How can a product owner prevent the build-up of technical debt?
A product owner can prevent the build-up of technical debt by ensuring quality assurance in each development cycle, advocating for best coding practices, and making sure any shortcuts taken are repaid as soon as possible.
Why is the Product Owner’s understanding of technical debt important for continuous improvement?
Understanding technical debt aids the Product Owner in striking a balance between feature delivery and code quality, thus maintaining high product performance and facilitating continuous improvement.
How does technical debt affect team morale?
Accumulation of technical debt can lead to a cluttered and complicated codebase. This often leads to frustration among development team members and can decrease morale and productivity.
Can sometimes taking on technical debt be a strategic move?
Yes, sometimes teams may intentionally take on technical debt to achieve quick gains or meet deadlines. However, it’s crucial that this debt is managed and paid off quickly to avoid escalation.
How should a Product Owner prioritize paying off technical debt?
A product owner should balance the business value of new features against the risk of accumulated technical debt. When the risk or impact of a debt item is high, it should be prioritized for repayment.
How can accumulating technical debt hurt customer satisfaction?
Technical debt can lead to issues such as bugs, system outages, and reduced product performance. If not addressed quickly, this can lead to diminished customer experience, reducing overall satisfaction.
How does the Scrum framework help in managing technical debt?
The Scrum framework encourages regular inspection and adaptation, which enables teams to identify, prioritize, and address technical debt consistently during each sprint.
What is the role of the Product Owner in decision making related to technical debt?
The Product Owner decides how much technical debt the team should take on based on the product value. They also prioritize the repayment of technical debt in the product backlog.
How can transparency about technical debt help in its management?
Transparency about technical debt allows all stakeholders, including the Product Owner, to understand its impact on the product quality and timeline. This empowers them to make informed decisions about tackling it.
Can neglecting technical debt lead to increased project costs?
Yes. Neglecting technical debt can result in a complicated codebase, leading to longer development time, decreased productivity, and potentially requiring more resources to fix problems down the line – ultimately escalating the project’s cost.
How does a product owner’s grasp of technical debt influence product decision-making?
Understanding technical debt effectively equips the Product Owner with the ability to better weigh the risks associated with various product decisions, allowing them to choose options that are most favorable to both immediate results and long-term sustainability.
