Technical Debt
Also known as: tech debt, code debt, design debt
Definition
The long-term cost of taking shortcuts in software development today, which makes it harder to update and maintain the code tomorrow.
The implied cost of additional rework caused by choosing an easy or quick code solution now instead of using a better approach that would take longer.
Why it matters
Like financial debt, technical debt is not always bad. Taking a shortcut can help you ship an MVP to market faster. However, if you do not pay down that debt by clean-coding later, the interest compounds. Your development speed will slow to a crawl, and adding new features will become increasingly difficult.
Improvement tips
- Allocate a consistent percentage of each development cycle to refactoring and clean-coding old shortcuts.
- Document known areas of technical debt in your backlog so they can be prioritized alongside new features.
- Write automated tests to ensure that paying down tech debt does not break existing application logic.
Common mistakes
- Ignoring technical debt entirely until the codebase becomes too fragile to update safely.
- Assuming technical debt is purely a developer problem, failing to see how it slows down business growth.
- Treating all shortcuts as bad, failing to use deliberate tech debt to hit critical market deadlines.
