Delegator's Adjustment
The reasons for the delegator's adjustments can be different and related to selfish or cooperative
goals. In any case, these reasons cannot be irrespective of the delegator's trust in the trustee
about that specific task. Suppose that
Delegates(Ag

, and that
Ag
1
intends to change
that delegation. Suppose also that
Ag
1
is achieving goal
g

, with

.
We can have five main delegator's adjustments:
Reduction of delegation

, the delegator adjusts the original delegation, by
reducing the task that the
contractor must realize
(the client reduces the task to a subpart of the previous requested task).
For example, the delegator no longer trusts the trustee to complete the more complex action
(see Figure 7.17).
