Aleph: a detector for electron-positron annihilations at Lep

Process-centred Software Engineering Environments (PSEE) are the most recent generation of environments supporting software development activities. Most of PSEE are based on mechanisms promoting enforcement and automation of processactivities. In this kind of mechanisms the process modelsare prescribed in a detailed and complete way. But the experience shows that supporting processesis more concerned with the flexibility of guidance offered during the processperformance than with enforcement of a collection of predefined process models. In this paper, we present a solution to support strategic processesin a PSEE by providing a flexible guidance during processenactment.
