Our research activities are focused on formal specification based product and process quality improvement of a software system. We start with a formal specification based pragmatic view on software specification, software refinement, software enhancement and software testing. These features are further explored for the improvement of product and process quality. On the basis of these features w...

It is a challenge for small and very small organizations to adopt software process improvement models and the associated assessment methods to improve their software process. A number of customized assessment methods based on SPI models, such as CMM/CMMI and ISO 15504, have been proposed to fit the needs of such organizations. To help them select an assessment method relevant to their needs, th...

CMMI practices can be poorly implemented leading to weak performance gain. SCAMPI verifies model compliance but not performance. Hence, a framework to evaluate the quality of implementation of each practice, based on compliance and performance results, will prevent poor implementation, locate and fix problems, and ultimately achieve better results. In this paper we propose such a framework, bas...

The SOA Innovation Lab investigates the use of standard software packages in a service-oriented context. As a part of this investigation the SOA capabilities of products from different vendors need to be evaluated. For this purpose a SOA architecture maturity framework has been developed, leveraging and extending CMMI and TOGAF, as well as other state-of-the art frameworks and methods. Besides ...
