Step 1. Draw a Picture of the Production Process: PRT Planning

Start designing your Tracking Model by drawing a simple picture of the production process to be tracked. In order to make a complete representation, be sure to include all of the following in your illustration:

• All possible areas and paths through which the product can flow; ensure there are no gaps to prevent data leaks.
• Operator interfaces and devices that indicate a transition of items from one area to another.
• Detainment areas or regions where product is held or scrapped.

Example of a simple manufacturing process

Included are:

• All possible production paths.
• Production flow, indicated with arrows.
• Operator interfaces and devices where transitions take place.

1	Regions.
2	Operator interface stations.
3	Sensors.
4	Devices where transitions take place.
5	Product flow by using direction arrows.
6	All possible paths in the production process.
7	Detainment region for scrapped goods.
