x Running cases:number of instances executed for a given process or activity.
x Successful cases: number of instances for a given process or activity that completed their execution
successfully.
x Failed cases:number of instances for a given process or activity that finalized their execution with a failure
state.

x Aborted cases:number of instances for a given process or activity that did not complete their execution.
This methodology also defines and uses the following behavioural metrics proposed in [8]:
x Turnaround: Measures the gross execution time of a process instance or activity.
x Wait time: Measures the elapsed time between the entrance of a process or activity in the system and the
assignment of the process or activity to a user prior to the start of its execution.
x Change-over time: Measures the elapsed time between the assignment of the process or activity to a user
and the start of the execution of the process or activity.
x Processing time: Measures the net execution time of a process instance or activity.
x Suspend time: Measures the time an execution of a process or activity is suspended.
Likewise, this methodology incorporates the performance dimension that is defined as a quality factor in [9]. The
following measures refer to the performance dimension, and we adapt them to this methodology as KPIs that can be
inferred from the metrics defined above. Below it is outlined the most relevant ones.
