Technical debt is a common concept in software development, where team leaders delay features and functionality, cut corners, or settle for suboptimal performance to push the project forward. It occurs due to a “build now, fix later” mentality, and this article will show you how to avoid that problem.

Crafting Code Without Burden: A Developer’s Guide to Avoiding Technical Debt.

Introduction

In the fast-paced world of software development, the term “technical debt” has become increasingly prevalent. Developer Ward Cunningham coined the term technical debt. Cunningham was one of the authors of the Agile Manifesto and former head of research and development at Wyatt Software. During his time at Wyatt Software, Cunningham wrote in a report for the 1992 OOPSLA conference: Shipping first-time code is like going into debt. A little debt speeds development so long as it is paid back promptly with a rewrite. The danger occurs when the debt is not repaid. Every minute spent on not-quite-right code counts as interest on that debt. Entire engineering organizations can be brought to a standstill under the debt load of an unconsolidated implementation.

Companies that delay or omit work for the sake of speed accrue technical debt, which they need to pay back later or face consequences. What exactly is technical debt, and why should developers be concerned about it?

What is Technical Debt?

Technical debt, also known as tech debt or code debt, describes what results when development teams take actions to expedite the delivery of a piece of functionality or a project that needs to be refactored later. It represents the extra development work that arises when a team chooses a quick and easy solution now instead of using a better approach that would take longer. In other words, it’s the result of prioritizing speedy delivery over perfect code.

Causes of Technical Debt

Understanding the sources of technical debt is crucial for preventing its accumulation. Let’s delve into the key contributors to this coding burden.

Lack of Documentation

When changes in the codebase are not properly documented, it leads to knowledge gaps. This lack of clarity can result in challenges for team members who may struggle to understand the rationale behind specific code modifications or updates. Inadequate documentation also hinders the onboarding process for new team members, slowing down their ability to contribute effectively.

Furthermore, the absence of comprehensive documentation may lead to increased debugging time, as developers must spend additional effort deciphering the code’s functionality. Addressing this issue requires a commitment to thorough documentation practices, ensuring that the codebase remains transparent and accessible for all present and future team members.

Technological Evolution

Solutions that were optimal when implemented can quickly become outdated as new technologies, frameworks, or better practices emerge.

Using obsolete or deprecated technologies can create technical debt as they become hard to maintain and integrate with newer solutions. Regularly assess the software stack and update outdated technologies to avoid accumulating technical debt due to unsupported or obsolete integrations.

Rushed Development

Teams may opt for quicker and less optimal solutions in the race to meet tight deadlines. Technical debt arises when shortcuts are taken in the software development process, especially during rushed development cycles. In the pursuit of quick project completion, organizations may incur technical debt, leading to poorly functioning applications and subsequent time wasted on addressing avoidable technical issues. Organizations should adopt proactive measures to manage technical debt effectively within their development cycles to mitigate these challenges. This involves dedicating time upfront to develop comprehensive project plans and conducting thorough testing at every solution implementation. By adhering to these practices, development teams can confidently navigate their sprints, maximizing efficiency and ensuring the creation of a robust and high-quality product.

Team Dynamic

Inconsistent coding practices among team members can lead to a disjointed and complex codebase. Within many organizations, development teams may be working on various branches simultaneously, leading to a lack of code cohesion when the finished product is merged into a single code base. The more code creation occurs in siloes, the more technical debt emerges. Where vital knowledge is siloed between departments, teams, and individuals, this causes business productivity to diminish through a lack of communication, training, and mentoring.

Consequences of Ignoring Technical Debt

Neglecting technical debt comes with a price that extends beyond the initial development phase. Let’s explore the aftermath of turning a blind eye to this coding burden.

Increased Costs

As technical debt accumulates, the complexity of the codebase grows. Over time, the cost of addressing technical debt escalates. Fixing accumulated problems requires more effort, resources, and time, resulting in higher expenses compared to addressing them promptly. These costs can extend to software updates, system overhauls, employee training, and potential loss of business opportunities.

Decreased Productivity

Teams constantly bogged down by a legacy codebase riddled with technical debt often spend more time fixing bugs.

System Outages and Failures

A codebase with significant technical debt is often fragile and prone to errors. Outdated or poorly optimized software and processes hinder productivity and efficiency. Developers may struggle with slow processing speeds, convoluted workflows, and inadequate tools, leading to frustration.

Managing and Reducing Technical Debt

When addressing technical debt, it’s essential to strike a balance between time, quality, and cost, considering the software development team’s governance model, toolset, and mindset. Achieving the right mix in this equation is crucial, and while not the sole factor, selecting the appropriate technology can also play a significant role.

Effectively addressing technical debt requires proactive strategies. Here are key practices to manage and reduce this coding burden.

Prioritizing Debt Reduction

To effectively manage technical debt, it’s essential to prioritize debt reduction as an integral part of the development cycle. This involves establishing a systematic approach to identify and assess different types of technical debt, categorizing them based on their impact and urgency. By prioritizing debt reduction, development teams can allocate resources strategically, focusing on addressing critical technical debt items that substantially impact system performance, scalability, or maintainability.

Regular Refactoring

Refactoring is the process of improving code structure internally without changing its desired behavior. As the development requirements change for a project, the other previous code creation may become obsolete or hard to update for future coding or business needs. As refactoring is pushed back, the tech debt becomes bigger.

Refactoring involves modifying the code to improve its structure, readability, and efficiency without altering its external behavior.

Automated Testing and CI/CD

Automated tests provide a safety net that allows developers to confidently make changes, knowing that errors or issues will be caught early. Embracing automated testing and continuous integration/continuous deployment (CI/CD) methodologies becomes paramount in mitigating these risks.

In software development, rushing to meet a release deadline without conducting comprehensive testing or code reviews is comparable to taking shortcuts when laying your foundation. While the code may appear to work initially, it risks harboring hidden bugs and inefficiencies that could cause problems.

Awareness and Documentation

It is crucial to create awareness among team members about the impact of technical debt and the importance of avoiding shortcuts that lead to it.

Effectively manage technical debt by documenting and monitoring it, fostering awareness among team members and stakeholders. Emphasize technical debt impacts development speed and quality to instill a collective responsibility for its resolution. Ignoring tech debt is one of the biggest concerns. If you’re going to use it effectively, keep a record of it and make it a regular part of your development conversations.

Conclusion

Much like financial debt affecting an individual or organization’s growth, unmanaged technical debt can severely impact software projects’ health, efficiency, and success. Prioritizing debt reduction, regular refactoring, automated testing, and fostering awareness are key steps in crafting code without the burden of technical debt.

While some technical debt may be inevitable, most of it surely can be preventable. No one wants to spend time doing extra work. Getting ahead of it before it becomes a problem later down the road is one way to ensure that you, your operations, your business, and most importantly, your code are clean and debt-free moving forward. By adopting these practices, developers can ensure the longevity and resilience of their software projects in the ever-evolving landscape of technology.
