To group resources further, your organization may define a hierarchy of ?. j1 p7 U& H0 J3 V+ z- @! v
work areas. For example, a plant may include a welding line, a lathe2 f- k- I; ]7 q. J8 _4 H
workstation, a milling workstation, and an inspection workstation. The, m( w% [ ^2 T( i$ Y! b
welding line may contain a welding workstation and a welding work cell.

process designer provides work instructions on how to configure the work0 U8 a5 V- R* O! N4 _$ G; o
