The default function of ISAAP is a selection of aspiration and
reservation levels (that define the corresponding CAF)
for each active criterion
(Section 4.4.3 describes changing of a criterion status).
For each criterion the last specified
component achievement function
ui(qi) is plotted11.
The aspiration and reservation levels can be set
by using either the mouse or a keyboard.
Clicking the mouse results in moving the nearest (either aspiration
or reservation) point to the point where the mouse is currently
pointing to.
This is the easiest and fastest way of setting those values.
The exact values for aspiration and reservation
levels can be displayed and updated from a pop-up window, which can be
created by selection of the Values item from the ISAAP menu.
Aspiration and reservation levels must not be
too close (cf. [Mak94b] for more detailed information).
Should the specified values for those levels for a criterion
be close, then either they have to be modified, or the criterion status
has to be changed for the stabilized one.
Therefore, if such a case is detected,
the user is asked to either change the aspiration and/or
reservation levels or the status of the criterion.

- More exactly, a projection of
values of the ui(qi) on the interval [0, 1] is plotted.
