By its nature, engineering is a quantitative discipline. Product metrics help software engineers gain insight into the design and construction of the software they build by focusing on specific, measurable attributes of software engineering work products. Chapter 23 provides knowledge of product metrics. | These slides are designed to accompany Software Engineering: A Practitioner’s Approach, 7/e (McGraw-Hill 2009).
