Lean Manufacturing Methodology & Strategy

A: Governing principle: Pull systems are constrained by physical WIP, not software intent. Applied here: If container quantity is wrong, the loop over- or under-buffers regardless of visuals or ERP setup. Common trap: Option B catches people who know escalation matters but skip verifying the math that sets inventory exposure.

A: Governing principle: Takt is a demand constraint, not a machine capability. Applied here: An 85 s asset feeding a 60 s takt cell guarantees starvation unless capacity is added or work is split. Common trap: Option D attracts engineers focused on cycle definition, but even a perfect cycle still misses takt.

A: Governing principle: Jidoka addresses quality at the source, not ergonomic exposure. Applied here: Silent andon removes stop-the-line and escalation, but doesn’t change physical motion demands. Common trap: Option C pulls people who equate jidoka with flow control rather than defect containment.

A: Governing principle: Setup reduction is demonstrated by measured delta, not intent. Applied here: Without before/after timing tied to task separation, SMED is unverified. Common trap: Option B appeals to procedural thinkers who accept documentation in place of evidence.
