Ward Cunningham coined the metaphor “technical debt” (also known as code debt or design debt) in software development in 1992. It illustrates a scenario where the software development team chooses an easy, short-term solution instead of implementing a more labor-intensive and optimal strategy.
Technical debt is based on the philosophy of monetary debt analogy, in which compounding interests run incessantly as a result of unpaid debts.
Is Technical Debt a Bad Thing?
Technical debt arises due to a lack of direction and mutual understanding among team members regarding a project’s goals and long-term thinking. Technically, it may not sound like a bad thing, but it can be counterproductive in the course of time if not addressed immediately.
Is Technical Debt Predictable?
Companies seldom want to see their product incurring considerable technical debt, but it is mostly predictable.
Why?
Because your project will never see the light of day (i.e., coming out of the development stage) if your tech team keeps on waiting and waiting till every line of code is perfect. Besides, when you choose a short-term fix, you end up having weaker software conflicting with your business requirements.
However, organizations can monitor and manage tech debt through various strategies, including setting coding standards, identifying signs of debt, prioritizing tasks, writing automated tests, and branching the codebase.
Repercussions of Technical Debt in Software Development
Even if technical debt occurs due to some unavoidable circumstances, you cannot procrastinate fixing it. The longer your tech team waits to deal with the cruft, the more it will compound the issues, leading to a labor-intensive fixing of the faulty software design adhering to new changes.
How to Know If a Project has Encountered a Technical Debt?
- It will signal a subtle sign known as Code Smell, indicating something problematic in the source code.
- When you see technologies overlapping each other due to higher levels of code complexity
- When an entire system crashes due to bugs
- When the coding style is inappropriately refactored
- When the project conflicts with compatibility with other software or hardware, encounters security hacks, or has slow performance, etc.
5 Points Indicating the Cause of Technical Debt
Organizations seldom want to encounter technical debt, but some factors account for its genesis. It could be planned, unintentional, or unavoidable. Let’s find out.
1. Attempting to Save Costs on the Budget
In contrast to what most companies do to reduce costs and speed up development to save costs on budget, what pans out eventually defeats the initial approach. For example, deploying minimal resources, leveraging a poor tech stack, and dedicating less time to a project collectively lead to technical debt.
2. Rushing the Project Development
3. Development Processes not Aligned with the Team
When the development team lacks a well-documented concept regarding the project development, it causes confusion and no desired coordination among team members, coupled with a lack of test automation.
4. Lack of Experienced Tech Team
5. Poor Quality Testing
Testing is one of the most vital parts of any software development lifecycle, ensuring that the product functions satisfactorily on the required quality parameters. Ignoring the necessary testing due to limited QA support or rushing the project to market creates technical debt over time.
A strong recommendation is adopting a DevOps model for automated efficiency in your software development lifecycle.

Step-by-Step Guide to Manage and Reduce Technical Debt
1: Assess the Tech Debt
When figuring out what causes the tech debt, chances are that you may come across a variety of contributory factors, including low-performance ratings of the app or developers spending much time iterating.
One of the ways to measure this is to understand the number of days required by the developers to fix technical debt by deploying a host of activities, including application replacement or code refactoring. Once done, initiate a cost/benefit analysis based on the remaining days before the software release date and lay out a projection of how you want technical debt to change over time.
2: Involve Technical Debt as a Part of the Discussion Topic with your Developers
Continuously remind your developers about technical debt so they stay focused on long-term improvement, flexibility, and scalability throughout project development. While the occurrence of tech debts is unavoidable, ensure that you are drawing the borderline in compromising your decision and whether it is reasonable and for how long. For example, if the code quality is a bit problematic, you need to ensure that it will be addressed later when you have a new component library.
3: Acknowledge that Tech Debt Exists
One of the most important, or perhaps the easiest, ways to handle tech debt is acknowledging its existence and letting your key stakeholders know the same. If communicated well about the genuine cost of tech debts, the chances of playing down its existence would be none, thus enabling your developers to manage it efficiently.
4: Use Automated Testing
If the project development lifecycle is put on a strict timeline, it becomes challenging for a development team to ensure the quality of the software release. Under such circumstances, without resorting to cutting corners, organizations can adopt automated testing to reduce resource deployment on manual testing, thereby helping them focus on quality deliverables within the deadline.
Moreover, automated testing reduces code issues as it facilitates automated debugging cycles and initiates diverse other processes, ensuring code does not have problems once a module is updated.
Benefits of Automated Testing
- Enables rapid testing
- Reduces costs
- Helps developers save time to focus on other crucial tasks
- Boosts productivity level within the team
- Limits the possibility of encountering technical snags during the final development stage
5: Structure Project Better
This is one of the most efficient ways to handle tech debts. There are many project management tools, including Hive Trello, that can be leveraged to monitor development statuses and maintain schedules. Moreover, code issues can also be monitored for early fixes, whereas deploying code-analysis tools like SonarQube can help identify code-related problems and prioritize them accordingly.
6: Restructure Software Architecture
Restructuring the software architecture is a modern approach to reducing tech debt. From providing real-time data analytics to converting curated data into the desired state is the handiwork of an intelligent software architecture, among other capabilities it features.
Since most organizations rush to put their ideas on the market and initialize software development quickly, the process of building architecture gets hasty and accounts for tech debts, which they pay later through restructuring. Restructuring architecture or building a flexible architecture for your software is a viable solution for reducing tech debt. You are advised to choose a software architecture that promises security, scalability, and flexibility.
7: Set up Code Best Practices
Make sure that the coding standards to be followed in software development are well-documented, indicating best practices for developers to exercise. Developers adhering to the best practices and coding standards manage to avoid the chance of racking up tech debts significantly.
8: Initiate Refactoring the Source Code
Refactoring affords the best assistance for developers to deal with technical debt. Leverage it to change the source code’s quality without inflicting any changes to its external behavior. Refactoring alters the code written poorly or changes filthy code that occurs when developers fail to provide an immediate workaround. If initialized at regular intervals, refactoring may reduce existing tech debt while bringing efficiency to your code’s readability and maintainability.
Concluding Statement
Technical debt is an implication of additional rework on a project that was developed by following an easy and shortcut way rather than choosing a labor-intensive and more optimal approach by the development team. Similar to the monetary debt analogy, tech debts require fixing before the cruft compounds to a point of damaging a company’s return on investment. This means companies cannot afford to see the tech debt compounding over time by procrastinating on its immediate fixes.
Mentioned above is the detailed guide on a technology debt, its causes, and steps to manage it effectively so that you can help your business identify, manage, and decrease tech debts significantly. An ideal way to avoid the possibility of technical debt is to use reputable software development services that will ensure you walk through every stage of your software development lifecycle for a high-quality project release.
