What is Tech Debt Interest?
The ongoing cost of working around poor code quality, making every future change slower and riskier.
Why It Matters
Like financial debt, technical debt compounds over time, making development progressively slower if not addressed.
Real-World Example
A poorly structured database that adds 2 extra hours to every feature that touches user data.
“Understanding terms like Tech Debt Interest matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
