Read the first 6 Quality Management flashcards as text

  1. What is the primary purpose of a 'process capability index' (Cpk)?

    Answer: To quantify how well a process produces output within specification limits

    Cpk measures how centered and spread a process is relative to its specification limits, indicating whether the process is capable of meeting customer requirements.

  2. What is 'lean manufacturing' primarily focused on?

    Answer: Eliminating waste (muda) from processes to maximize customer value

    Lean manufacturing, derived from the Toyota Production System, focuses on identifying and eliminating eight types of waste to streamline processes and deliver maximum customer value.

  3. In quality management, what is a 'Pareto chart' used for?

    Answer: Ranking defects or problems by frequency to identify the vital few causing most issues

    A Pareto chart combines a bar chart and line graph to show that roughly 80% of problems come from 20% of causes, focusing improvement efforts on the highest-impact issues.

  4. What is the purpose of a 'cause-and-effect diagram' (Ishikawa/fishbone diagram)?

    Answer: Visually organizing potential causes of a quality problem by category

    The Ishikawa (fishbone) diagram organizes potential root causes of a problem into categories (e.g., Man, Machine, Method, Material) to structure brainstorming and analysis.

  5. What distinguishes 'quality assurance' from 'quality control' in engineering management?

    Answer: Quality assurance focuses on process improvement to prevent defects; quality control focuses on detecting defects in outputs

    Quality assurance (QA) proactively improves processes to prevent defects, while quality control (QC) reactively inspects outputs to detect defects before delivery.

  6. What does 'poka-yoke' mean in lean and quality management?

    Answer: A mistake-proofing device or method that prevents errors or makes them immediately obvious

    Poka-yoke (mistake-proofing) refers to any mechanism in a process that helps prevent errors or immediately detects them before they become defects.
