Core concepts
Concept 1
Lean Improvement Tools questions reward the answer that follows the official source, the professional role, and the stated facts.
Exam cue: Identify the candidate role, client or public risk, source rule, calculation, or process step being tested.
Concept 2
The strongest answer identifies the rule, safety concern, ethical duty, calculation, client factor, or process step before acting.
Exam cue: Check whether the fact pattern is using a national standard, jurisdiction rule, handbook policy, or scenario-specific instruction.
Concept 3
Eliminate answers that ignore requirements, skip documentation, overreach the role, or treat convenience as the standard.
Exam cue: Choose the compliant and professionally scoped answer before the convenient or familiar answer.

Setup Reduction
Setup reduction lowers changeover time and supports smaller batches.
Kanban
Kanban signals replenish work or material based on actual demand.
Pull System
A pull system limits overproduction by producing to downstream need.
Visual Management
Visual management makes status, standards, and abnormalities visible.
Cellular Flow
Cellular flow arranges work to reduce handoffs and movement.
Error Proofing
Error proofing makes the wrong action impossible or obvious.
Batch Size
Smaller batches can reduce waiting, inventory, and feedback delay.
Workplace Organization
Organized workplaces reduce search time, motion, and errors.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
