Functional needs-based perspective

The crisis of the GME method is closely related to the crisis in the density matrix approach to wave-function collapse. We shall see that in the Poisson case the processes making the statistical density matrix become diagonal in the basis set of the measured variable and can be safely interpreted as generators of wave function collapse, thereby justifying the widely accepted conviction that quantum mechanics does not need either correction or generalization. In the non-Poisson case, this equivalence is lost, and, while the CTRW perspective yields correct results, no theoretical tool, based on density, exists yet to make the time evolution of a contracted Liouville equation, classical or quantum, reproduce them. 

By integrating the cooperative work perspective to our NATURE based metamodel, we have been able to extend the PRIME process support in order to support the cross-functional interplay among developers. More precisely, PRIME is able to remotely trace the process enactment at several workplaces and transfer information from one to the other, when needed, using a shared ontology that obeys company policies and rules. In order to show the effectiveness of the distributed process support, we have implemented a tool called cooperation console that is able to visualize the workflow of elementary activities of the design process, provide information concerning its execution status, and to unfold the design history for each developer. 

The task analysis provides a structured description of the activities that permits a high-profiling of the task, the context ofworkandthe users needs. However, task analysis is more focused on what the operators are expected to do than on how they actually perform their activities from their own perspective. Another method, based on user scenarios, seems to be more suitable to examine user activities from the visual perspective (e.g. location, gaze direction, affordances and constraints on movement) and generate functional and usability specifications for virtual environments (VE). The critical hnk for this information is the fact that for each node of the task model (especially critical decision-points), the important performance shaping factors and tools to be used are recorded. They are...
