Technical Debt
Definition
Technical debt is a concept in software development that reflects the implied cost of rework caused by choosing an easy (limited) solution now instead of using a better approach that would take longer.
Why It Matters
Accumulating technical debt is like taking out a financial loan: it gives you a short-term benefit (faster delivery), but you have to pay "interest" on it later in the form of increased maintenance costs, more bugs, and slower development.
Contextual Example
To meet a deadline, a team decides to skip writing automated tests for a new feature. This is technical debt. Later, when they need to make changes, they have to spend extra time manually testing everything, and bugs are more likely to slip through.
Common Misunderstandings
- Not all technical debt is bad. Sometimes, it is a conscious business decision to take on debt to get a product to market faster.
- Refactoring is the process of "paying down" technical debt by restructuring existing computer code without changing its external behavior.
