Knowledge management approaches for weakly-structured, adhoc knowledge work processes need to be lightweight, i.e., they cannot rely on high upfront modeling efforts. This paper presents TaskNavigator, a novel prototype to support weakly-structured processes by integrating a standard task list application with a state-of-the-art document classification system. The resulting system allows for a task-oriented view on office workers' personal knowledge spaces in order to realize a proactive and contextsensitive information support during daily, knowledge-intensive tasks. Moreover, TaskNavigator supports process know-how reuse by proactively suggesting similar tasks or relevant process models, based on textual similarities. Finally, we report on a feasibility test and a case study that have been conducted in order to evaluate the system in the context of daily research task management and software requirements analysis.

In this paper, we present a system to proactively provide software process participants with information items that are available and relevant in the context of their current tasks. Knowledge on which items to offer is obtained in two ways. First, situation-specific information needs that arise for participants are captured, together with the information sources that are accessed to satisfy them. These are recommended to other participants in similar situations using collaborative filtering techniques. Second, to allow for more systematic recommendation functionality, a formal language is provided to specify preconditions on when to offer certain information items. The resulting hybrid system thus supports an incremental phase-in of knowledge management techniques into an organization, allowing the organization to decide how much effort to spend on knowledge engineering.

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.
