Pattern AP4: REPLACE Process Fragment

This pattern enables the replacement of a process fragment by another one. Like AP3, pattern AP4 can be implemented based on patterns AP1 and AP2 (Insert/Delete Process Fragment) or be directly based on change primitives.


A process fragment is replaced by another process fragment in process schema S.


For a particular patient a planned computer tomography must not be performed in the context of her treatment process due to the fact that she has a cardiac pacemaker. Instead of the computer tomography activity, the X-ray activity shall be performed.


A process fragment is no longer adequate, but can be replaced by another one.



This adaptation pattern can be implemented based on patterns AP1 and AP2 (insert / delete process fragment) or based on change primitives.
