Decision Centred Design

First Generation

Red light => Shut down is simple RPD

BUT

At a management level, there is uncertainty over
Goals, Courses of Action, Expectancies

Uncertainty is not managed => loss of performance

Third Generation

Management level now in the Control Room

Getting the full history on plant, operational constraints etc seen as big advantage

BUT

Potential for information overload, knowing when to stop information gathering

Difficulty in weighting information, separating myth from fact

SO

Use agent-mediated communication between stakeholders, with Group Decision Support

Not real-time, but fast for off-line
