AnswerClick to flip back
A
They are cheapest to find in the early development phases and the most expensive to fix in the latest test phases.
💡 Explanation:
Finding and fixing faults early in the development lifecycle (such as during requirements or design) is significantly cheaper than resolving them in later test phases or post-release. Fixing bugs late requires expensive rework across multiple development phases.
