Understanding Technical Debt
Technical debt refers to the implied cost of additional rework caused by choosing an easy or limited solution now instead of using a better approach that would take longer. This article explores the implications of technical debt.
Exam Question
Which of the following statements about technical debt (rework created by technical shortcuts and brittle or outdated legacy applications) is true?
(choose the best answer)
A. The existence of technical debt is a sign of poor development practices.
B. Technical debt is a technical concern only of interest to developers.
C. Technical debt can be handled post-release as part of maintenance work.
D. Technical debt is a threat to the long-term viability of a product.
Correct Answer
D. Technical debt is a threat to the long-term viability of a product.
Explanation
Correct Answer
D. Technical debt is a threat to the long-term viability of a product:
Technical debt accumulates when teams take shortcuts or avoid necessary refactoring, leading to increased complexity and reduced maintainability over time. If not addressed, it can slow down development, increase the risk of bugs, and make future changes more difficult and costly. Hence, it poses a significant threat to the long-term viability of a product.
Incorrect Answers
A. The existence of technical debt is a sign of poor development practices:
While technical debt can result from poor practices, it is not always the case. Sometimes technical debt is a conscious decision to meet immediate deadlines with the plan to address it later. It can be a strategic choice rather than a sign of poor practices.
B. Technical debt is a technical concern only of interest to developers:
Technical debt affects the entire organization, not just developers. It impacts the product’s maintainability, flexibility, and overall quality, which in turn affects business goals and customer satisfaction. Therefore, it is a concern for the entire Scrum Team and stakeholders.
C. Technical debt can be handled post-release as part of maintenance work:
Deferring technical debt to post-release can be risky as it might accumulate and become harder to manage over time. Addressing technical debt should be an ongoing effort integrated into regular development activities to ensure the product remains maintainable and adaptable.
Agile Leadership Insights
- Visibility: Agile leaders should ensure that technical debt is visible and acknowledged within the team and to stakeholders. This helps prioritize technical debt alongside new feature development.
- Prioritization: Addressing technical debt should be balanced with delivering new features. Agile leaders need to prioritize tasks effectively to maintain product health and innovation.
- Continuous Improvement: Encourage a culture of continuous improvement where technical debt is regularly addressed. This involves setting aside time in each iteration to tackle debt.
- Collaboration: Technical debt is a shared responsibility among all team members, including the Product Owner, Scrum Master, and Developers. Effective collaboration helps manage and reduce technical debt.
