Study Notes

Quality Management System

Quality is meeting customer expectations, and improvement focuses on enhancing products and reducing waste.

Prominent Figures

W. Edwards Deming: Defines quality as meeting or exceeding customer expectations. His total quality management philosophy is expressed in 14-points for improving quality, productivity, and competitiveness. Advocated a PDSA cycle for systematic improvement, emphasizing data analysis, employee involvement, and continuous improvement.
Philip Crosby: Introduced the concept of "zero defects," emphasizing quality as a management responsibility. Prevention is more effective than correction.
Joseph Juran: Focused on quality planning, control, and improvement (quality trilogy). Emphasized leadership in fostering a quality culture.

Dimensions of Quality

Degree to which products meet customer specifications: Specific and measurable. Performance exceeding expectation or not meeting expectations.
Durability: Products lifespan.
Conformance: Products meet codes.
Reliability: Ability to perform without failure.
Aesthetics: Sense appeal (color, sound, feel comfort).
Features: Added convenience and comfort.
Performance: Doing intended work
Perceived Quality: Impression of the product by the customer (reputation).
Serviceability: Ease and speed of repair and maintenance (availability).

Service Quality (SERVQUAL)

SERVQUAL model has ten dimensions of service quality (convenience, courtesy, consistency, reliability, responsiveness, assurance, time, tangibles, expectations). Key dimensions include reliability (dependable and accurate delivery), responsiveness (speedy and eager help), tangibles (appearance of facilities), credibility (trustworthy and honest), competence (skills), access (availability to customers), empathy (individualized care/attention), assurance (knowledge) and courtesy, and communication by keeping customers informed and secure, protecting personal information..

Quality Costs

Cost of good quality (Prevention costs + Appraisal costs): Prevention costs (planning, maintenance, training), and appraisal costs (inspections, calibration, and audits).
Cost of poor quality (Internal failure costs + External failure costs): Internal failure costs (rework, scrap, delays), and external failure costs (customer returns, warranty claims, low quality image).

Quality Management Tools

Check sheets: Data gathering forms organizing data, useful for tracking.
Pareto analysis: Visual representation identifying the most significant issues.
Histogram: Frequency distribution useful in identifying patterns.
Scatter Diagrams: Cause and effect relationships.
Control charts (SPC- Statistical Process Control): Determine process stability (variables over time/data trends)
Cause and effect diagrams (Ishikawa or Fishbone diagrams): Identifying possible causes of an issue.

Quality Improvement

Reduction of variability in processes and products. Quality engineering focuses on design, development, and manufacture meeting or exceeding expectations and consumer requirements.

Acceptance Sampling

Inspection of a sample to evaluate the entire product lot. Two types: outgoing inspection (after production) and incoming inspection (before production use).

ISO 9001

International standard for quality management systems. Organizations use this to demonstrate their ability to provide products/services consistently meeting customer/regulatory requirements.
ISO 9001:2015, is the latest version, and includes a Plan-Do-Check-Act (PDCA) cycle for continual improvement.

Statistical Process Control (SPC)

Control charts used to monitor process variability and ensure process stability over time/data trends.
Two types of charts: Attribute (count data; p, np charts) and Variable (numerical data; x-bar, R charts).
