CPASA: Continuous Performance Assessment of Software Architecture

Software architecture is a very important factor when it comes to performance measurements. A large percentage of projects failing their potential performance characterisation was caused by badly configured architectures. Performance assessment of software architectures proved to be a successful way of preventing this risk. Non-functional requirements verification is still an uncharted area in agile development. CPASA provides a method for assessing the performance requirements using the system architecture as a base for conducting the performance study. In this paper, we introduce the steps in the CPASA method and the technical description of how to deploy this method.
