DOCUMENT INFO
Description: This document sets forth certain Quality Assurance (QA) Metrics that a business can use to measure the quality system requirements of a product or service. While quality control focuses on output, QA focuses on input and imperfections or mistakes in the production process. This document provides a formula and data items to measure the following QA metrics: effort variance, schedule compliance, defect slippage, requirements stability, effort distribution by phase, schedule variance, defect seepage, total defect percentage, and bug logging defect density.
