What is Technical Debt?

The implied cost of additional rework caused by choosing a quick solution now instead of a better approach that would take longer.

Technical debt is a metaphor comparing shortcuts in code to financial debt — borrowing speed now costs interest (maintenance burden) later. Types include deliberate debt (conscious trade-offs for deadlines), accidental debt (poor design due to inexperience), and bit rot (code degrading as requirements evolve). Symptoms include slow feature development, frequent bugs, long onboarding times, and fear of changing code. Managing technical debt requires tracking it explicitly, allocating time for repayment (refactoring sprints), preventing accumulation (code review, testing), and making debt visible to stakeholders. Some technical debt is strategic; unmanaged debt is dangerous.
