- Applying Roles to the SFB 501 Experience Base (2000)
- For transferring existing knowledge into new projects, reuse has become an important factor in today's software industry. However, to set reuse into practice, reusable artifacts have to be stored somewhere, and must be offered to (re-)users on demand. For this purpose, advanced reuse repository systems like, for instance, instantiations of the Experience Base concept, are quite frequently used. Many people, from different projects, have to access such a repository at various phases of software development processes to retrieve or store reusable data. In order to fulfill the given tasks, each of these user has specific needs. Taking this into account, a reuse repository has to offer tailored user interfaces and functions for different user groups. Furthermore, since the contents of such a repository usually represent the state of the art of an organization's (core) competencies, not everyone should be allowed to freely access each and every repository entry. This isespecially true for persons that are not part of the organization. This report discusses role concepts that can be applied to reuse repository systems to overcome some of the stated access problems. Commonly used roles for software development and reuse repository management are listed. Based on these roles, a basic set of roles, as implemented in the SFB 501 Experience Base, is introduced.
- Tools for supporting the Software Engineering Laboratory of the SFB 501 (1999)
- Using an experience factory is one possible concept for supporting and improving reuse in software development. (i.e., reuse of products, processes, quality models, ...). In the context of the Sonderforschungsbereich 501: "Development of Large Systems with Generic methods" (SFB501), the Software Engineering Laboratory (SE Lab) runs such an experience factory as part of the infrastructure services it offers. The SE Lab also provides several tools to support the planning, developing, measuring, and analyzing activities of software development processes. Among these tools, the SE Lab runs and maintains an experience base, the SFB-EB. When an experience factory is utilized, support for experience base maintenance is an important issue. Furthermore, it might be interesting to evaluate experience base usage with regard to the number of accesses to certain experience elements stored in the database. The same holds for the usage of the tools provided by the SE LAB. This report presents a set of supporting tools that were designed to aid in these tasks. These supporting tools check the experience base's consistency and gather information on the usage of SFB-EB and the tools installed in the SE Lab. The results are processed periodically and displayed as HTML result reports (consistency checking) or bar charts (usage profiles).
