Access the Time Management panel
Use the Time Management panel to create or modify activities that workers must perform for specific operations to manufacture products on a line.
Procedure
Search for and open an existing work package, or create one and open it.
Navigate to work package planning tasks, and then navigate to the Process Planning page.
In the Process tab or panel, select an operation, and in the page toolbar, click Show Time Management .
The Time Management panel replaces the Viewer panel and displays a list of activities associated with the selected operation.
(1)
The name of the operation selected in the Process panel. Below the operation name are the names and descriptions of all activities that are currently displayed in the Time Management panel.
(2)
Duration displays the sum of all currently displayed activity work time values in the selected operation, 11.52 + 2.16 + 2.16 = 15.84. Time units of measure, in this case seconds, are displayed in the page header.
(3)
The activity code and unit time values for each activity.
(4)
The quantity and frequency, as well as the time category of activities to be completed. These values are editable and changes to them impact work time and duration. Example Changing the quantity of the Response time activity from a value of 2 to 4 doubles that activity's total work time to 4.32. The additional work time is added to the duration sum, 15.84 + 2.16 = 18.0.
(5)
The Work Time column displays the total time necessary to complete the activity. Work time - unit time * (quantity * frequency).
(Optional) Create a time activity from another activity or from an MTM.
To close the Time Management panel and return to the Viewer panel, click Show Time Management .
