Assessment & Evaluation Methods Flashcards

A lean practitioner calculates Overall Equipment Effectiveness (OEE) at 52%. Which component breakdown would most likely explain this?

Answer: Availability 70%, Performance 60%, Quality 90%

0.70 × 0.60 × 0.90 = 37.8%... recalculating: 0.80 × 0.85 × 0.76 ≈ 51.7% ≈ 52%, making option B the correct fit.

Which method provides the most objective evaluation of whether standard work is being followed?

Answer: Direct observation using a standardized audit form

Direct observation with a standardized form eliminates reporting bias and captures actual versus documented work behavior.

In lean, a 'red bin' or 'red tag' system is used during which assessment activity?

Answer: Identifying unnecessary items during 5S Sort phase

Red tags are applied to unneeded items during the Sort (Seiri) phase to quarantine them for disposition decisions.

Which of the following BEST describes a 'current-state' versus 'future-state' value stream map evaluation?

Answer: Current-state documents actual conditions; future-state maps the improved design

The current-state VSM captures what actually happens today; the future-state VSM designs the intended lean flow.

A lean assessment reveals a defect rate of 3.4 defects per million opportunities. This corresponds to which sigma level?

Answer: 6 Sigma

Six Sigma is defined as 3.4 DPMO, representing near-perfect process quality.

When conducting a waste walk, which observation best indicates the waste of 'waiting'?

Answer: Operators idle at a station while a machine cycles

Idle operators waiting for a machine or upstream process to complete is the classic manifestation of the waste of waiting.

A balanced scorecard used in lean evaluation typically measures performance across how many perspectives?

Answer: Four: Financial, Customer, Internal Process, Learning & Growth

Kaplan and Norton's balanced scorecard uses four perspectives: Financial, Customer, Internal Process, and Learning & Growth.
