What is technical debt?
Technical debt refers to the additional work that needs to be done in the future due to code shortening or patching during software development. Just like financial debt, technical debt accumulates over time and can become increasingly difficult to manage if not addressed promptly.
There are many different factors that can contribute to technical debt, such as tight deadlines, lack of resources, and multiple change requests. It can also occur due to low code quality, outdated technology, and inadequate testing.
Types of Technical Debt
There are two main types of technical debt: active and passive. Proactive technical debt is intentionally incurred, usually to meet a deadline or deliver a product quickly. On the other hand, passive technical debt is the result of poor quality code or lack of developer knowledge.
Active technical debt can be classified into four types:
- Intentional : This type of technical debt is intentionally incurred to gain a competitive advantage or to meet a specific business need.
- Reckless : Technical debt is recklessly incurred without due consideration of the long-term consequences.
- Prudence : Prudent technical debt arises after careful consideration of potential risks and benefits.
- Strategic : Strategic technical debt arises as part of a long-term plan to achieve a specific goal.
Where does technical debt come from?
Technical debt can arise from a variety of sources, including:
- Rushed deadlines : Rushing to meet deadlines often leads to sloppiness in architectural design and coding.
- Lack of documentation : Incomplete or outdated documentation can make it difficult for developers to understand and maintain the source code.
- Inexperienced developers : Teams with inexperienced members can produce code that lacks extensibility, reusability, and maintainability.
- Changing requirements : Rapidly changing project requirements can lead to quick fixes instead of comprehensive solutions.
- Inheriting legacy systems : Working with outdated or legacy systems can cause technical debt due to the need to integrate new technology with old technology.
- Inadequate testing : Skipping or incomplete testing can lead to bugs and issues going undetected, leading to technical debt accumulating over time.
Addressing these causes is critical in managing and reducing technical debt in software projects.
Learn the consequences of Technical Debt
While taking on technical debt may seem like a quick and easy solution in the short term, it can have serious long-term consequences. Here are some ways that technical debt can impact the development team and the company:
Maintenance costs increase
As technical debt accumulates over time, maintaining code stability becomes increasingly difficult and time-consuming. This can lead to higher maintenance costs for the company as the development team has to spend more time fixing bugs and resolving issues caused by technical debt.
Reduced productivity
Technical debt can also have a negative impact on a development team's productivity. As they spend more time dealing with technical debt, they have less time to research new features or improvements, leading to delays in project delivery.
Reduced quality
When the development team takes many shortcuts (temporary problem-solving solutions, for example copy-pasting code instead of refactoring, or ignoring errors to let the software run instead of investigating the cause... ) in the source code, it can lead to poor product quality and an increased number of bugs. This not only reduces user experience but also negatively affects the company's reputation.
Difficulty in expansion
As technical debt accumulates, it becomes increasingly difficult to scale the product or add new features. This can limit growth potential and hinder an organization's ability to respond to changing market demands.
Employees leave
Working with technical debt can be frustrating and demotivating for development teams, leading to high employee churn rates. This can incur costs for the organization, such as the cost of recruiting and training new employees.
How to reduce technical debt?
While it's impossible to completely eliminate technical debt, there are strategies that can help reduce its impact on the development team and the organization. Here are some ways to effectively manage technical debt:
Prioritize and plan
The first step to reducing technical debt is to prioritize it and create a plan to manage it. This involves identifying code segments that need attention and creating a plan to address them. It is important to involve all stakeholders in the process to ensure that everyone is on the same page.
Reconstruct
Refactoring involves making changes to the source code without changing the functionality of the software. This can help improve the quality of the code and reduce technical debt over time. It is important to regularly schedule refactorings to keep the code clean and maintainable.
Automated testing
Implementing automated testing can help detect bugs and issues early, reducing the risk of accumulating technical debt. Automated testing can also help identify code segments that need refactoring or improvement.
Continuous integration and delivery
Continuous integration and delivery (CI/CD) is a methodology that involves automating the process of building, testing, and deploying source code changes. This can help detect problems early and prevent them from turning into technical debt.
Education and training
It's important to educate and train development teams on coding best practices and the importance of managing technical debt. This can help prevent passive technical debt and promote a culture of continuous improvement.
