CRE Corrective Action and Continuous Improvement Flashcards

Value Stream Mapping (VSM) is a lean tool primarily used to:

Answer: Identify waste and visualize the flow of materials and information in a process

VSM maps the current and future state of a value stream to identify non-value-added activities (waste) and target improvements.

A Pareto chart in reliability improvement is used to:

Answer: Identify the vital few failure modes that cause the majority of problems (80/20 principle)

Pareto charts rank failure causes by frequency or impact, helping teams focus on the few issues causing most of the failures.

In Total Productive Maintenance (TPM), Overall Equipment Effectiveness (OEE) is calculated as:

Answer: Availability × Performance × Quality

OEE = Availability × Performance × Quality, capturing the three main sources of equipment effectiveness loss.

Kaizen events in a continuous improvement program are characterized by:

Answer: Rapid, focused team improvements to a specific process within a short timeframe (days to a week)

Kaizen (Japanese for 'change for better') events are short, intensive workshops where a cross-functional team implements process improvements rapidly.

Warranty data analysis is used in reliability improvement programs to:

Answer: Identify field failure modes and prioritize corrective actions for future designs

Warranty data provides real-world failure information that guides root cause investigations and design improvements for future product generations.

A FRACAS (Failure Reporting, Analysis and Corrective Action System) is designed primarily to:

Answer: Systematically capture, track, analyze, and close out failures from test and field environments

FRACAS closes the loop on every failure by ensuring it is reported, analyzed for root cause, and corrected with tracked actions.
