On the need for a process for making reliable quality comparisons with industrial data

Laurie Williams
2004 Software engineering notes  
Many factors influence quality data obtained from industrial case studies making comparisons difficult. In this paper, two longitudinal industrial case study experiences are shared which illustrate the complications that can arise. The first is a case study of an IBM team that transitioned to the use of test-driven development. The primary quality measure was functional verification test defects normalized by lines of code. The second case study was performed with an Extreme Programming team at
