    Study Notes

    Quality Management Overview

    • Total quality management (TQM) aims to ensure excellence in all aspects of products and services, focusing on customer needs.
    • Quality depends on the involvement of everyone in the production process, including stakeholders related to production and consumption.
    • Two key operational goals are careful product/service design and ensuring systems consistently produce the design.
    • Quality is defined as the set of characteristics enabling a product/service to meet customer needs, both explicit and implicit.
    • Leaders in the quality movement define quality as conformance to requirements (Crosby), predictable uniformity and reliability at low cost (Deming), and fitness for use (Juran).

    Quality Specifications

    • Quality specifications depend on strategic decisions, including design quality (product value in the marketplace) and conformance quality (extent to which design specifications are met).
    • Several attributes define design quality, such as performance, features, reliability/durability, serviceability, aesthetics, and perceived quality.

    Cost of Quality

    • Cost of quality refers to all costs associated with producing quality that's not 100% perfect.
    • It's the difference between what's expected from excellent performance and the current costs.
    • Costs often include rework, scrapping, repeated services, inspections, and warranties.
    • Some estimates put costs of quality at 15-20% of sales dollars.

    Cost of Quality Measurement

    • Measurement of quality costs is essential for several reasons:
    • Failure analysis
    • Cheaper prevention
    • Performance measurement for production systems

    Costs of Quality (4 Types)

    • Appraisal costs: Costs of inspection and testing to ensure product/process acceptability.
    • Prevention costs: Costs to prevent defects.
    • Internal failure costs: Costs due to defects within the system (e.g., scrap, rework, repair).
    • External failure costs: Costs of defects that reach the customer (e.g., replacements, warranties, complaints, repairs).

    Six-Sigma Quality

    • Six Sigma is a philosophy and set of methods to eliminate defects in production processes.
    • The goal is to achieve a maximum of 3.4 defects per million opportunities.
    • Defects are events where a product or service fails to meet customer requirements.
    • Six Sigma uses the DMAIC cycle: Define, Measure, Analyze, Improve, Control.

    Six Sigma Methodology

    • The DMAIC cycle is a continuous improvement method.
    • It focuses on understanding customer needs and reducing variations in processes.

    Defects Per Million Opportunities (DPMO)

    • DPMO is a metric to measure process performance.
    • It requires three pieces of information:
      • Unit: Number of items produced or served.
      • Defect: Any item/event that fails to meet customer requirements.
      • Opportunity: Chance for a defect to occur.
    • Examples demonstrate the calculation and interpretation and its application for calculating defects out of every million.

    The Shingo System

    • Shingo System is a philosophy focused on preventing defects rather than avoiding them.
    • It emphasizes a probabilistic approach and avoiding defects at the point of occurrence.
    • It promotes employee involvement in quality control, and use of fail-safe mechanisms (e.g., poka-yokes).

    Standardization, Certification, and Assessment

    • Quality certification approaches can be either prescriptive or non-prescriptive.
    • Prescriptive models (e.g., ISO 9001, ISO 14001) define standards for process/procedure implementation.
    • Non-prescriptive models (e.g., EFQM model, ServQual scale) describe desired outcomes without specifying achievement methods.

    Benchmarking

    • Benchmarking compares a business to best-in-class businesses to improve quality and operations.
    • This is done by identifying the best performer, who sets the standard and what that standard is.
