Which technique is MOST effective for evaluating whether a lean improvement has achieved its intended outcome?
Answer: Pre- and post-implementation measurement of the same KPIs
Measuring the same KPIs before and after provides objective evidence of whether the improvement delivered the expected results.
In a lean process capability study, a Cpk value of 0.85 indicates:
Answer: The process is not meeting customer specification limits reliably
A Cpk below 1.0 means the process variation is not fully within specification limits, producing defects.
A team uses a Kano model during a lean evaluation. 'Must-be' requirements in this model refer to:
Answer: Basic expectations customers assume without asking
Must-be requirements are threshold expectations that cause dissatisfaction when absent but don't increase satisfaction when present.
When a lean team reviews escape defects (defects that reach the customer), the assessment metric is called:
Answer: Escaped defect rate / external failure rate
Escaped or external defect rate measures quality failures that pass through all internal checks and reach the customer.
Which lean assessment method involves recording what percentage of time workers spend on different activity types through random observation?
Answer: Work sampling
Work sampling uses random observations at defined intervals to estimate the proportion of time spent on various activities.
A hoshin kanri X-matrix is used in lean evaluation to:
Answer: Align annual objectives, improvement priorities, targets, and ownership in a single view
The X-matrix links strategic objectives, annual priorities, improvement targets, and accountable teams on one page to ensure alignment.
During a lean audit, 'error proofing' effectiveness is evaluated by checking:
Answer: Whether poka-yoke devices physically prevent or detect errors before defects can be passed on
Effective poka-yoke evaluation confirms the device actually prevents or immediately detects errors, not just that it exists or workers know about it.
