What is Technical Debt

Written by Sam McNaull | Jan 18, 2023 3:00:00 PM

Technical debt is a term used to describe the cost of maintaining and updating existing software systems, often as a result of poor design or short-term decision making. The term is used to describe the trade-off between taking short-term action to meet immediate needs and taking long-term action to minimize the total cost of ownership.

When a software system is first developed, it is often built quickly to meet a specific requirement, but over time, as the system evolves, new features are added and the codebase becomes more complex. This can result in a situation where the codebase is difficult to understand, maintain and update, leading to increased costs and delays in delivering new features. This is known as technical debt. This debt can be managed and paid off by refactoring the code, rewriting parts of the system, or by introducing new technologies or frameworks. This can be done incrementally over time to minimize the impact on the system while still improving its maintainability and scalability.

Dealing With Technical Debt?

Dealing with technical debt can be a difficult undertaking, but there are several ways that can be deployed to minimize its impact on a department:

  1. Prioritize and plan: Identify areas of the codebase where technical debt is most critical, and prioritize these areas for refactoring or replacement. Create a plan to address the most critical areas first, and then work on the less critical areas over time.
  2. Refactor code: Refactoring the codebase can help to improve its maintainability and reduce the cost of technical debt. This can include things like breaking down large classes into smaller, more manageable ones, or removing redundant code.
  3. Introduce new technologies: Introducing new technologies or frameworks can help to improve the scalability and maintainability of a system, and reduce the impact of technical debt. This can include things like using a newer programming language, or adopting a microservices architecture.
  4. Continuous improvement: Incorporate continuous improvement into the development process, by regularly reviewing the codebase and identifying new areas of technical debt.
  5. Monitor and measure: Keep track of the technical debt, by monitoring and measuring the costs associated with maintaining and updating the codebase.
  6. Education and training: Provide education and training for the development team to help them understand the impact of technical debt, and give them the skills they need to reduce it.
    It's important to note that dealing with technical debt is an ongoing process, it requires continuous effort and resources, and it's not always possible to completely eliminate it but it can be managed and controlled to minimize its impact on the organization.
