Technical Debt : Business Analysis Explained

Technical debt is a concept in software development that reflects the implied cost of additional rework caused by choosing an easy solution now instead of using a better approach that would take longer. It is a critical aspect of business analysis, as it can significantly impact a project’s timeline, budget, and overall success.

This term was coined by Ward Cunningham, a computer programmer who is also one of the authors of the Agile Manifesto. He used the metaphor of financial debt to explain to non-technical stakeholders the consequences of cutting corners in software development.

Understanding Technical Debt

Technical debt can be intentional or unintentional. Intentional technical debt is a strategic decision made by the development team to expedite the delivery of a project, with the understanding that there will be a cost to pay in the future. Unintentional technical debt, on the other hand, is the result of poor practices or lack of knowledge, and it often goes unnoticed until it causes significant problems.

Just like financial debt, technical debt incurs interest. This “interest” is the extra time and effort required to fix problems and refactor code in the future. If not managed properly, the “interest” can compound, leading to a “debt crisis” where the cost of servicing the debt exceeds the capacity of the team.

Types of Technical Debt

There are several types of technical debt, each with its own causes and implications. Code debt refers to issues in the codebase itself, such as code smells, duplication, and lack of documentation. Design debt is related to problems in the system architecture or design. Testing debt arises when there is insufficient testing, leading to undetected bugs and issues. Finally, infrastructure debt is caused by outdated or inefficient infrastructure.

Understanding these types of technical debt is crucial for business analysts, as it allows them to identify potential risks and issues in a project, and to communicate these effectively to stakeholders.

Implications of Technical Debt

Technical debt can have serious implications for a business. It can slow down the development process, as time and resources are spent on fixing issues instead of developing new features. It can also lead to lower quality products, as bugs and issues are more likely to occur in a codebase with high technical debt.

Furthermore, technical debt can increase the risk of project failure. If the debt is not managed properly, it can reach a point where it is impossible to continue development without a significant investment in refactoring or even rewriting the codebase. This can lead to delays, cost overruns, and in the worst case, project failure.

Managing Technical Debt

Managing technical debt is a critical aspect of business analysis. It involves identifying, measuring, and prioritizing technical debt, as well as developing strategies to pay it off. This requires a deep understanding of the project, the technology, and the business context.

Business analysts play a key role in this process. They act as a bridge between the technical team and the business stakeholders, communicating the implications of technical debt and the need for investment in quality.

Identifying Technical Debt

The first step in managing technical debt is to identify it. This can be done through code reviews, automated tools, and retrospectives. Code reviews involve examining the codebase for issues such as code smells, duplication, and lack of documentation. Automated tools can help identify potential issues in the codebase, while retrospectives can provide insights into the causes of technical debt.

Business analysts can facilitate this process by ensuring that there is a shared understanding of technical debt among the team, and by promoting practices that help identify technical debt, such as regular code reviews and the use of automated tools.

Measuring Technical Debt

Once technical debt has been identified, it needs to be measured. This can be challenging, as technical debt is not a tangible asset that can be easily quantified. However, there are several metrics that can be used to estimate the size of the technical debt, such as the cost of delay, the cost of remediation, and the impact on productivity.

Business analysts can help in this process by working with the technical team to define these metrics, and by communicating the results to the business stakeholders in a way that they can understand and act upon.

Paying Off Technical Debt

Paying off technical debt involves investing time and resources in refactoring the codebase, fixing issues, and improving practices. This can be a difficult decision, as it often means delaying the delivery of new features. However, it is a necessary investment to ensure the long-term success of the project.

Business analysts can support this process by advocating for the importance of paying off technical debt, and by helping to prioritize the debt items based on their impact on the business.

Technical Debt in Agile Development

In Agile development, technical debt is a particularly important concept. Agile teams work in short iterations, delivering small increments of functionality at a time. This approach can lead to the accumulation of technical debt if quality is not maintained.

However, Agile also provides tools and practices to manage technical debt effectively. For example, the practice of continuous refactoring, where code is regularly reviewed and improved, can help prevent the accumulation of technical debt. Similarly, the use of automated testing can help detect and fix issues early, reducing the cost of remediation.

Technical Debt and Scrum

In Scrum, one of the most popular Agile frameworks, technical debt is managed through the product backlog. The product owner, with input from the team, is responsible for prioritizing the backlog items, which can include tasks to pay off technical debt.

Business analysts can play a key role in this process by helping the product owner understand the implications of technical debt, and by facilitating the prioritization process.

Technical Debt and Kanban

In Kanban, another Agile framework, technical debt is managed through the use of explicit policies. The team can define policies for dealing with technical debt, such as dedicating a certain percentage of their capacity to paying off debt, or addressing high-priority debt items as soon as they are identified.

Business analysts can support this process by helping the team define and implement these policies, and by monitoring their effectiveness.


Technical debt is a critical aspect of business analysis. It can significantly impact a project’s timeline, budget, and overall success. Therefore, understanding and managing technical debt is essential for any business analyst.

Through effective identification, measurement, and prioritization of technical debt, business analysts can help ensure the long-term success of a project. They can also play a key role in communicating the implications of technical debt to business stakeholders, and in advocating for the necessary investment in quality.
