Summary form only given. We propose an approach to facilitating not only project enactment but also project planning and monitoring, by tracking all decisions made during project planning and enactment and managing dependencies between these decisions. In order to identify those dependencies relevant for a decision, we established an extendable model of planning and plan enactment, which explicitly describes the activities likely to occur while planning and enacting a software development project, as well as standard dependencies between these activities. We formalized this model by adapting an existing dependency management system, the Redux Model of Design, to record planning and plan enactment decisions and their dependencies. Furthermore, we are currently identifying heuristics to automatically capture typical dependencies, and defining rules to provide automatic planning support where possible. This approach allows to interleave planning and plan enactment, and to feed enactment data back into the plan, either by automatically reacting to enactment events and plan changes, or by notifying the appropriate person(s). Thus, we provide extensive support for the process of planning and enacting software development projects, in the form of dependency management, user notifications, and, where possible, automation of selective process steps.

Software development processes are highly creative, and therefore prone to change frequently. Also, recent developments show that most software projects require knowledge and skills in a lot of areas. Since the necessary expertise often cannot be found at one development site, the necessity arises to distribute projects among several sites, or form "virtual" corporations, where software development is shared between several companies. The first point makes it necessary to support changes by identifying and notifying the people affected by a change. The second point emphasizes this necessity, while also complicating project planning and management: changes in one development site or company might necessitate replanning in several locations. In this paper, we introduce the MILOS approach, which provides concepts to integrate process modeling, planning, scheduling and enactment in one system. Thus dynamic plan changes, as well as automated feedback from execution to the project plan can be supported.

The MILOS system supports software development processes over the Internet.It integrates process modeling with project planning and enactment.Our flexible workflow engine allows refining and changing process models during project execution, The built-in traceability component supports change notifications and helps the project participants to ensure that the project plan as well as the state of the enactment engine reflect the "real world development process.Tool integration is accomplished by using the built-in capabilities of Web browsers.
