Measures (P)

Measures are process step properties used for process analysis. They describe both the input values for the evaluation and the calculated performance indicators.

 

All available measures are summarized in the table below. The I/O column specifies if this is an input measure for which an aggregated output measure is calculated (I/O) or if it is only a calculated output measure (O) or if it is only an input measures (I). If Break time or Lead time is an I/O measure then automatically the other one must be an output measure. You can decide which one is an input measure in the Measures settings.

 

The Steps column specifies the step types that are using the given measure.

Notice that there are two measures specified on the process level: Start date and Results multiplier.

By Activity we mean here Automatic, Manual, Computer, Internet, Telephone, Other, Decision, Meeting and Teamwork step types and all custom step types based on Task.

By Break we mean here the Break step type and all custom step types based on Break.

By Total we mean here the aggregated results for Start and Stop steps as well as results for the whole process.

 

All values here are averages calculated for one process case.

Process cycle efficiency %

Value added time divided by lead time and multiplied by 100.

O

Total

Processing to lead time ratio %

Processing time divided by lead time and multiplied by 100.

O

Activity, Total

Processing time

I/O

Activity, Total

Relative cost

Cost of an activity multiplied by its relative throughput

O

Activity

Relative processing time

The amount of work time an activity was busy for a case

O

Activity

Relative throughput %

Total cost

Variable cost plus fixed cost

O

Break, Activity

Throughput (cases/min.)

Number of cases exiting the process step in the interval of one minute

O

All steps

Value added lead time

Lead time while ignoring non value added activities and queuing time.

O

Total

Variable cost

The cost of an activity calculated as the amount of work necessary to perform it multiplied by the tariff (cost/hour) of the relevant role(s)

O

Activity, Total

Velocity (task/min.)

Number of tasks executed by a case in one minute time.

O

Total

Work in progress (observed)

Observed number of cases in execution

Initially, only few measure properties are visible. These are Processing time, Break time (or Lead time), Total time, Relative throughput and Result multiplier. You can make the other visible using Select measures dialog. You can also set up the way the measures are presented (e.g., the time format) using Measures settings.
