Integrating the feature space with input from informants, stakeholders and exemplars can help considerations of the future for architecture and of the assets Integration is also valid since not all domains may be suited to strict OO approaches. Pia Maria Maccario mentioned her experience in service orientation which cuts across objects. In this case, the use extensions to OO methods documents feature interaction. The group identified several issues that will challenge the move to integration. Many reuse efforts are built on legacy systems.
Conflicts exist in the use of shared data vs. encapsulation of data.
In addition, there are problems of integrating legacy systems with objects. An answer here may be encapsulation. To make the case for reuse, we need metrics for reuse work products. There are no suitable metrics for domain models nor for frameworks or patterns. 5.0 Trends The group saw an growing movement of OO techniques toward a priori methods.
