Abstract

Contemporary software processes and modeling languages have a strong focus on Functional Requirements (FRs), whereas information of Non-Functional Requirements (NFRs) are managed with text-based documentation and individual skills of the personnel. In order to get a better understanding of how capacity requirements are handled, we carried out an interview series with various branches of Ericsson. The analysis of this material revealed 18 Capacity Sub-Processes (CSPs) that need to be attended to create a capacity-oriented development. In this paper we describe all these sub-processes and their mapping into an extension of the OpenUP/Basic software process. Such an extension will support a process engineer in realizing the sub-processes, and has at the same time shown that there are no internal inconsistencies of the CSPs. The extension provides a context for continued research in using UML to support negotiation between requirements and existing design.
