Methods for change management in automotive release processes Christina Singer

Abstract

The handling of changes in automotive release processes is a fundamental challenge of today's development projects. This chapter examines strategies for the identification of the effects of changes and evaluates concepts for the estimation of resulting retest effort. It is determined that there exists no approach that is applicable for large systems at vehicle level and that allows a reliable selection of all tests necessary to analyze the impact of the change. To solve this problem, two general concepts for test selection techniques are proposed. Inclusion-based approaches identify tests from the set of not executed tests whereas exclusionbased approaches eliminate tests from the set of performed tests. The two concepts are compared via receiver operating characteristic and cost estimation. Furthermore, the exclusion-based test selection is described in detail. It offers the opportunity to reduce the automotive release effort without drawbacks in test quality.
