Which Industry 4.0 tool creates a virtual replica of a production line so engineers can test changes offline?

• Robot work-cell

• PLC controller

• Digital twin

• AGV cart

Which KPI is calculated as Availability × Performance × Quality?

• OTIF

• OEE

• MTTR

• Yield

In the OEE equation, Performance % primarily compares:

• Good units vs total units

• Actual vs theoretical cycle speed

• Scheduled vs running minutes

• Supplier deliveries on time

A collaborative robot is installed at the end-of-line packing station to shorten cycle time. Which baseline KPI is it most directly meant to improve?

• Quality %

• Availability %

• Performance %

• OTIF

Which of the following is NOT typically captured directly by a shop-floor PLC?

• Cycle-complete signal

• Operator training hours

• Downtime reason code

• Part counter pulse

The main workforce benefit of a transparent KPI dashboard is to:

• Eliminate all paperwork

• Give operators a shared “score-card” that drives engagement

• Remove the need for maintenance staff

• Replace the MES entirely

When convincing suppliers or distributors of reliability, the single most persuasive KPI is:

• On-Time-In-Full (OTIF) delivery rate

• Mean Time To Repair (MTTR)

• Scrap rate

• Energy per part

In a SMART improvement goal, the letter T stands for:

• Technology

• Time-bound

• Training

• Throughput

Which risk–mitigation pair is correctly matched?

• Technical risk: operator push-back → weekly huddles

• Human risk: PLC integration clash → offline simulation

• Technical risk: network latency → upgrade industrial switches

• Human risk: data leak → redundant robot grippers

Real-time IoT dashboards usually trigger a mobile alert when:

• The CAPEX budget is exceeded

• A KPI drifts outside its control limits

• Operators complete their training

• An ERP report is printed
