Craftsman Smart Factory case studies
Craftsman Smart Factory · Put your knowledge to work in context.
The Craftsman Smart Factory credential is a vendor-neutral, multiple-choice examination aimed at technicians, line engineers, and production supervisors who work where operational technology meets information technology. It tests whether a candidate can reason across the whole plant rather than only inside one machine: how sensors and gateways feed data upward, how PLCs and robots are coordinated, how that data becomes a digital twin or an analytics input, and how security and safety constraints shape every design choice. The Craftsman Smart Factory case studies are 5 cases and about 2,438 words.

A contract manufacturer is six weeks from replacing its legacy MES with a new system across two plants and 40 production stations. ERP integration is built, but master-data reconciliation found 3,200 item records with an 11% mismatch rate; critical attributes such as lot control and unit of measure are affected.
