Empirical Analysis of the Performance-related Risk

The current methods of effort estimation frequently take indirect account of the tasks of software performance engineering (SPE), and provide widely differing conclusions. In order to create transparency and acceptance for this task that has been growing in importance for years in the context of the life cycle of IT systems, an approach (PRM Performance Risk Model) is adopted that derives resource requirements from a corresponding risk analysis, and conversely looks at the business system to be supported, the software development and the operational environment. After a short introduction of the current situation and a look behind the PRM-model itself, this paper describes first experience by the use of the PRM-model within 6 industrial projects.
