The Evolution of a Software Measurement Program

摘要

An engineering organization needs measurements. Competitive pressures demand a quantitative understanding of the contributors to project cost and schedule, such as process productivity and product quality (which drives rework). The integration of measurement and analysis activities into project processes supports: 1. Objective planning and estimating; 2. Tracking actual performance against established plans and objectives; 3. Identifying and resolving process-related issues; 4. Providing a basis for incorporating measurement into additional processes in the future. This paper discusses practical lessons learned from establishing and evolving such a measurement system, emphasizing the use of centralized metrics. It addresses requirements and design of a centralized repository, as well as cultural issues arising from its use over time.
