Chapter 14 Testing Process Maturity Models Objectives • • • Testing process should be measured for its maturity and improvement.

Need for Test Process Maturity • • • The progress and quality of the whole test process should be measured, and the results should be used as input for further test process improvement. The testing process steps, i. e. test planning, design, execution, etc. are in place. There is a systematic flow of these activities in the organization. Provides the important information to the testers and management enabling them to improve the software quality. The model should be able to improve the process such that it provides the information about the bugs near to their source, i. e. exact location of their existence leading to minimization of correction costs. The model should be able to improve the process such that it detects high priority or criticality bugs earlier. 2 © Oxford University Press 2011. All rights reserved.
