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

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.
Selecting Measures:
You can decide what measures will be visible for a process. Open or select this process in Diagrams pane and press the Select button in the Measures group in Analysis tab.
Check the measures you want to use and press OK. You will see these measures properties in the Properties pane in the Input measures and the Results categories. Some input measures will also appear in the Mini property editor.
Since the End date can only be determined when the Start date is provided, by selecting the Start date you actually select also the End date.
What is the 'show measures' tab for?
Showing/hiding measure balloons:
In order to show measure values on the process diagram press the Measures button in the Show / hide group of the Layout tab. An additional pane Show measures will be opened.
It will contain a list of the selected measures (if the list is empty click Select measures link to open the Select measures dialog). There are two columns of check boxes in front of the measure names: B (below) and A (above).
You can decide what measures are to be shown in balloons below a process step by clicking the corresponding check box in the B column of the Show Measures pane.
Note that because of the lack of space a short name for a measure (e.g. PT for processing time) is used in the balloon (this name is also shown in the parentheses in the Show Measures window). The process layout is expanded vertically in this case to create space for the balloons with the measures. Up to 7 measures can be shown in a balloon. If a measures is not defined for a certain process step it is not shown in the balloon. For example, Relative cost (RC) is shown only for a task.
Measure balloons are never shown together with the input/output or RASCI balloons. So, if you press the Measures button while the Input/Output or RASCI button is on the measures balloons will appear and the other balloons will disappear.
Measure values can also be presented above steps.
