Developing high quality software

Performance related problems are a key aspect in the software development process (SDP). In particular an early integration of performance considerations inside the SDP has been recognised during last years as an effective approach to speed up the production of high quality software. In this paper we present a design process that can help in producing high reliable software with predefined performance requirements. We propose the use of a performance plug-in to the ArgoUML CASE tool which allows to insert performance indices based on the OMG Profile for schedulability, Performance and Time Specification standard (Object Management Group, UML Profile for Schedulability, Performance and Time Specification ver 1.1, 2005) for the design of the software architecture. It also permits to map an UML model toward stochastic Petri Nets, which are used as the performance specification and evaluation tool.
