By KatarzynaPosted on Tue, September 19, 2023

What is Technical Debt?

In the world of software engineering, technical debt (also known ad code debt) is a concept that has become a crucial aspect that engineers, developers, and project managers must understand and manage. Technical debt is a concept coined by Ward Cunningham, a renowned software developer, in the early 1990s. He used this metaphor to describe the trade-off between implementing a quick and potentially unsatisfactory solution to meet a deadline or address an immediate need versus taking the time to design and implement a more robust, maintainable, and scalable solution. Just like monetary debt, it accrues interest over time and can ultimately become a significant burden if left unaddressed.

How is Tech Debt Made?

m_checklist-1266989_1280(7).png At its core, tech debt represents the compromises made during software development. These compromises can take various forms, including:

  1. Code Quality: Rushed coding practices, legacy code, hacks, and shortcuts, that make the code less readable and maintainable.
  2. Incomplete Documentation: Incomplete or inadequate documentation, making it harder for future developers to understand and work with the code.
  3. Bypassed Testing: Neglecting thorough testing or skipping test-driven development, which increases the risk of introducing bugs and issues.
  4. Outdated Dependencies: Failing to update third-party libraries or frameworks, leading to security vulnerabilities and compatibility problems.
  5. Lack of Scalability: Building a system that works for current needs but is not easily adaptable to future requirements or increased user loads.

What Are the Types of Technical Debt?

It represents the trade-off between taking shortcuts or making quick decisions to expedite development and the long-term costs and challenges that these decisions may incur. Code debt can be broadly categorized into two main types: intentional and inadvertent. In this article, we will explore these two types of technical debt, their characteristics, implications, and strategies for effectively managing them.

Intentional Technical Debt: A Calculated Gamble

Short-term gain: Intentional technical debt is accrued purposefully by development teams, often in situations where there are pressing deadlines, the need to deliver features rapidly, or other compelling short-term factors. In such cases, developers consciously choose to cut corners or implement temporary solutions to meet immediate business objectives. Inconsiderable debt speeds development, but it needs to be repaid promptly so that it does not accumulate and become a major setback.

Awareness: Unlike inadvertent tech debt, which may be incurred due to lack of knowledge or unforeseen complexities, intentional technical debt is acquired with full awareness. The team makes a conscious decision to prioritize speed over long-term quality.

Intention to address: The key characteristic of intentional technical debt is that there is an intention to address it in the future. It is like taking out a loan with a clear plan to repay it. The team recognizes that the shortcuts taken are a temporary measure and commits to revisiting and improving the code once the immediate need is met.

Intentional technical debt can be a strategic move when managed properly. It allows organizations to seize opportunities quickly, respond to market changes, or meet critical deadlines. However, it must be monitored and managed to ensure it doesn't accumulate beyond control and impede long-term development.

Inadvertent Technical Debt: The Unseen Culprit

Short-term gain: Inadvertent tech debt arises due to factors like a lack of experience, time pressure, or unforeseen complexities during development. Developers may not even realize they are accumulating tech debt until its consequences become apparent. Unlike financial debt, the tech debt may be easily overlooked and backfire at the later stage of your project.

Awareness: Inadvertent debt is accrued without a clear understanding of the implications. Developers may not be aware of the shortcuts or faulty decisions they make during the development process.

Intention to address: The critical difference here is that while inadvertent technical debt is not acquired intentionally, it should still be identified and addressed once discovered. Ignoring it can lead to increasing technical challenges and long-term maintenance issues.

Inadvertent debt can be insidious. It accumulates gradually, and its impact often becomes visible only when the software system becomes difficult to maintain or extend. Therefore, teams must remain vigilant and establish processes for identifying and mitigating inadvertent debt as part of their development practices.

4 Quadrants of Technical Debt

Technical debt can be categorized into four quadrants, each representing a different aspect of the debt.

  1. Reckless and Deliberate Debt (Quadrant I): This quadrant represents technical debt that is taken on knowingly and intentionally. In some cases, developers and teams may consciously choose to take shortcuts or make trade-offs to meet tight deadlines or deliver a product quickly. While this can be a strategic decision in the short term, it often results in higher costs and difficulties in the long run. Examples include not writing unit tests, skipping code reviews, or delaying necessary refactoring.

  2. Unintentional and Unforeseen Debt (Quadrant II): In this quadrant, technical debt is accrued unintentionally. Developers may not be aware of the long-term consequences of their decisions or may lack the experience to anticipate future problems. This type of debt typically arises from a lack of knowledge, inexperience, or poor communication within the development team. It can lead to unexpected issues and increased maintenance costs down the line.

  3. Strategic and Deliberate Debt (Quadrant III): Sometimes, technical debt is taken on strategically and with a clear understanding of its implications. Teams may decide to incur tech debt temporarily to gain a competitive advantage or to meet a critical market need quickly. The key difference between this quadrant and Quadrant I is that in Quadrant III, the team is aware of the debt and has a plan to address it in the future. It is a calculated risk taken for a specific reason.

  4. Inevitable and Unaddressed Debt (Quadrant IV): This quadrant represents technical debt that accumulates over time due to external factors or resource constraints. It is often the result of a lack of time, resources, or management support to address existing debt. This type of debt can become overwhelming and lead to significant challenges in maintaining and evolving the software. Examples include using outdated technologies, neglecting security updates, or not addressing scalability issues.

It is essential for programming teams to be aware of and manage technical debt effectively. While some debt may be necessary for strategic reasons, it is crucial to have a plan in place to address it (Quadrant III) and avoid letting it accumulate in Quadrant IV, where it can become a significant burden. Regularly assessing and prioritizing code debt can help ensure that software remains maintainable, secure, and adaptable in the long term.

Causes of Technical Debt

While it may seem expedient to cut corners in the short term, technical debt can have profound and lasting consequences on a business. To mitigate these risks, companies should adopt a proactive approach to manage and reduce technical debt, investing in regular maintenance, modernization, and adherence to best practices in software development and IT infrastructure management.

How to Repay Technical Debt

Tech debt needs to be tackled effectively so that such debt load does not cause your technical problems snowball.

Identify Technical Debt: The first step in repaying debt is to identify it. This involves conducting regular code reviews, static code analysis, and listening to feedback from your development team. Create a list of debt items, categorizing them by severity and impact.

Prioritize Debt Items: Not all technical debt is created equal. Prioritize the identified debt items based on their impact on the project and the effort required to fix them. Focus on high-impact, low-effort items first to get quick wins and build momentum.

Plan and Schedule: Repaying technical debt should be a planned and ongoing effort. Allocate time in your development schedule for addressing debt items. Consider dedicating a specific sprint or iteration solely to debt repayment.

Refactor and Improve: To repay tech debt, you'll often need to refactor existing code. This may involve rewriting sections of the codebase to adhere to best practices, improving documentation, and eliminating redundant code. Ensure that your refactoring efforts are well-tested to avoid introducing new issues.

Automate Where Possible: Use automation tools for code analysis, testing, and deployment to catch technical debt early in the development process. Continuous integration and continuous deployment (CI/CD) pipelines can help enforce coding standards and prevent debt accumulation.

Set Coding Standards: Establish coding standards and best practices within your development team. Encourage code reviews and enforce these standards to prevent the accumulation of technical debt in the first place.

Involve Stakeholders: Communicate with stakeholders, including product owners and managers, about the importance of repaying technical debt. Ensure they understand the long-term benefits of investing in code quality and maintenance.

Monitor and Measure Progress: Keep track of your technical debt reduction efforts. Metrics such as code complexity, code coverage, and bug counts can help you measure progress over time.

Documentation and Knowledge Sharing: Improve documentation to make it easier for developers to understand and work with the code. Foster knowledge sharing within your team to ensure that everyone is aware of the changes and improvements being made.
