Add data to process maps

On a process map, add data to shapes to help you better understand your process.

You can add the following data to shapes on a process map. After you add data to a shape, you can display it on the map. For more information, go to Display data on a map.
X variable
An X variable is an independent input variable that affects the outcome of a process. For example, vendors affect the delivery time and cost of parts. Therefore, vendor could be an X variable for a purchase parts shape.
Y variable
A Y variable is a dependent output variable of a process. For example, delivery time, and cost depend on the vendor. Therefore, delivery time and cost could be Y variables for a purchase parts shape.
Process Data
Process data describes the efficiency of your process. For example, you can add DPMO, yield, scrap and rework.
Lean Data
Lean data describes the value stream of a process. For example, you can add cycle time, standard deviation, FTE, and average queue.
Note

If the data you want to add are not in the Variables dialog box or the Process or Lean task panes, you can add it. For more information, go to Manage data fields from the task pane.

Add variables to a shape

  1. Right-click the shape, select Shape Data, then select Add Variables.
  2. In the Variables task pane, in the section for the variable you want to create, choose any of the following options.
    New
    Create a new variable.
    Move
    Move an existing variable to the selected shape.
    Copy X
    Create a new variable by copying an existing X variable.
    Copy Y
    Create a new variable by copying an existing Y variable.

Add process and lean data to a shape

  1. Choose to add process data or lean data.
    • To add process data, right-click the shape, select Shape Data, then select Add Process Data.
    • To add lean data, right-click the shape, select Shape Data, then select Add Lean Data.
  2. In the task pane, enter values for the data you want to add.

Add data to value stream maps

On a value stream map, add data to shapes to calculate a timeline. Add map data to calculate takt time.

Add data to process and inventory shapes

When you add data to process shapes and inventory shapes, the value stream map calculates a timeline. To ensure the timeline calculations are accurate, always add process data to process shapes and inventory data to inventory shapes.

  • To enter process data, right-click a process shape, choose Shape Data > Add Shape Data, then enter values for the data on the Process tab.
  • To enter inventory data, right-click an inventory shape, choose Shape Data > Add Shape Data, then enter values for the data on the Inventory tab. Inventory shapes include Inventory, Buffer Stock, Supermarket, and FIFO Sequence Flow.

Some data that you enter in the task pane appears beside the shape on the timeline and some data does not. To display data that does not appear, go to Display data on a map.

Note

If the data you want to add is not in the task pane, you can add it. Go to Manage data fields from the task pane. For more information on timeline calculations, go to Value stream map and timeline calculations.

Add map data

When you add map data, the value stream map calculates takt time. For information about how takt time is calculated, go to Value stream map and timeline calculations.

  1. Right-click the map's workspace, then choose Edit Map Data.
  2. In the Map task pane, in Customer Demand, enter a value per some unit of time.
  3. You can adjust the hours, shift, and break times.

Takt time is calculated and displayed in the upper right corner of the map. If takt time does not appear, choose Map > Takt Time.
