In practice, however, many providers of reusable components are not able to do so due to insufficient feedback and details from reusers. Additionally, they often have too little knowledge on system

In this paper we argue that such an integrated process should be fundamentally based on experience. We sketch an approach developed in the context of the EMPRESS project that shows how different kinds of experience- based artifacts, such as checklists, patterns, and rationale, can beneficially be applied.

An important issue in the adoption of the product-line approach is the migration of legacy software components, which have not been designed for reuse, systematically into reusable product-line components. This article describes activities performed to improve systematically the design and implementation of an existing software component in order to reuse it in a software product line. The activities are embedded in the application of Fraunhofer PuLSE TM -DSSA-an approach for defining domain-specific software architectures (DSSA) and product-line architectures. The component under investigation is the so-called Image Memory Handler (IMH), which is used in Ricoh's current products of office appliances such as copier machines, printers, and multi-functional peripherals. It is responsible for controlling memory usage and compressing and decompressing image data. Improvement of both the component's design and implementation are based on a systematic analysis and focused on increasing maintainability and reusability and hence suitability for use in a product line. As a result of the analysis and refactoring activities, the documentation and implementation of the component has been considerably improved as shown by quantitative data collected at the end of the activities. Despite a number of changes to the code, the external behavior of the component has been preserved without significantly affecting the performance.
