| 摘要≠ | Use case point (UCP) estimation quantifies software development effort by analyzing use cases and environmental factors. Introduced by Karner (1993) for Objectory methodology, UCP provides structured approach to estimate labor hours from system requirements. Organizations use UCP to forecast project duration, allocate resources, and validate high-level project plans early in development. | Defect prediction models forecast the likelihood of software faults in code modules using statistical or machine learning approaches. Pioneered by Ostrand, Weyuker, and Bell (2005), these models correlate code metrics (complexity, churn, coupling) with historical defect data to identify high-risk components. Organizations use predictions to allocate testing resources, guide code review, and prioritize refactoring. |
