In this section we illustrate our PSM-method for configuration of
methods. We start with an initial configuration problem: a diagnostic
case to be solved, plus assumptions and goals to be satisfied by the
diagnostic method that we will configure. We then pass through the various
steps of our method, each indicated with a 
. The entire succession of
steps is graphically depicted in Figure 9.
The amount of detail in which we have described the scenario might seem somewhat excessive. The reason for this amount of detail is that we can now ensure that each of the steps in our scenario is implementable. In fact, in [ten Teije & van Harmelen, 1996b] we have described an architecture which we have implemented using logic-programming and meta-reasoning techniques, and which is powerful enough to directly implement each of the steps that occur in the scenario of this section.
