Adapting and adjusting test process reflecting characteristics of embedded software and industrial properties based on referential models

Abstract

Test activities are very important for the product quality. Testability Maturity Model (TMM) and Test Process Improvement (TPI) are often applied to improve the test activities. However, in the domain of embedded software, there are many different concerns from that of other software domains to achieve the high quality. This paper deals with the characteristics of embedded software and industrial corporate challenges based on the referential models suggesting the TPI-EI (Test Process Improvement for Embedded software and Industrial characteristics) model. The TPI-EI model reflects the practical improvement strategies and focuses on the evaluation procedures with cost-effectiveness. In order to check if this model is valid, the result of applying this model is explained. The proposed model provides the foundation to find out the insufficient parts of test activities, ultimately improving the test capabilities upon the self-evaluation.
