Customer demand and facility data, which you enter on the Map task pane, are used to calculate takt time.
The cycle time required to match the pace of the customer demand. Companion uses the following equation to calculate takt time.
The cycle time of a process step is the time from one completed output to the next completed output. In Companion, when you enter cycle time values in the Process task pane, they appear in the troughs of the timeline. Typically, you enter Cycle Time or VA CT and NVA CT. If you enter all three values, Companion will display either Cycle Time or the sum of VA CT and NVA CT, whichever value is greater, on the top of the trough. VA CT is always displayed on the bottom of the trough.
If Cycle Time is less than or equal to 2 minutes, it is displayed in seconds. If Cycle Time is less than or equal to 2 hours, it is displayed in minutes.
If you enter VA CT and NVA CT on a process shape, cycle time is calculated on the timeline, but it is not calculated in the task pane.
The Line Balancing - VSM and the Value Stream Map Comparison forms do not recognize cycle time values on the timeline. If you plan to use these forms, you must enter cycle time values in the task pane.
Finished goods inventory time always uses the takt time equation.
In the cycle time equation, the following is true:
If you want to override calculated inventory time to use a known value, you must add the optional field, Inv Time to the value stream map task pane. For instructions on how to add data fields to the value stream map task pane, go to Manage data fields from the task pane.
When there are parallel shapes on the timeline, Companion displays the highest value on the timeline, and then uses that value to calculate total cycle time and/or lead time in the summary box.
You can include the following calculated data fields to timeline summary box by adding them to the Map task pane. For information about adding data fields to the task pane, go to Manage data fields from the task pane.
