This extended abstract summarises the current state of a thesis project in information systems engineering. The overall problem is to support planning, coordination, management and performance of work in knowledge intensive projects. The approach is to apply interactive process models created and updated by the project participants, to customise and control the behaviour of the computerised support system. A number of new and existing modelling techniques are combined to solve the identified problems of modelling by end users and flexible model-driven computer support. Model reuse is a core challenge both for increasing the usefulness of the models and for minimising the effort of modelling. An innovative framework that supports need driven model reuse has been designed. The contributions of this thesis are validated through prototype implementation, comparison with related work, and user experimentation in case studies. Concrete problem formulation and a definite target audience are identified as the main shortcomings at the current stage of the work.
