Design for Quality and Product Excellence

Chapter 12 explores the typical structured product development process consisting of idea generation, preliminary concept development, product/process development, full-scale production, product introduction, and market evaluation.

Concurrent engineering is a process in which all major functions involved with bringing a product to market are continuously involved with product development from conception through sales. Such an approach not only helps achieve trouble-free introduction of products and services, but also results in improved quality, lower costs, and shorter product development cycles.

DMADV

  • Define – identify the opportunity and clearly defining the issue to be addressed.
  • Measure – gather the voice of the customer and identify the vital CTQs. 
  • Analyze â develop product concept. 
  • Design – develop detailed specifications, design reviews, and approvals. 
  • Verify â develop prototypes, test, and plan for implementation.

Building the House of Quality

  1. Identify customer requirements.
  2. Identify technical requirements.
  3. Relate the customer requirements to the technical requirements.
  4. Conduct an evaluation of competing products or services.
  5. Evaluate technical requirements and develop targets.
  6. Determine which technical requirements to deploy in the remainder of the production/delivery process.

*Review the information from the Guidance in Week 2 – Voice of the Customer and the House of Quality – http://asq.org/learn-about-quality/qfd-quality-function-deployment/overview/voice-of-the-customer-table.html. Also, see http://www.webducate.net/qfd/qfd.html for an interactive tutorial for the House of Quality matrix.

Statistical Process Control

Chapter 13 presents the basic concepts of statistical process control. These include purposes, control charting techniques, design and analysis of charts, managerial requirements for implementation of SPC, and SPC considerations within service organizations.

SPC Metrics

  • An attribute is a performance characteristic that is either present or absent in the product or service under consideration (e.g., in or out of tolerance, error/defect present or absent).
  • Expressed as proportions or rates
  • Variable data are continuous (e.g., length, weight, and time).
  • Expressed with such statistics as averages and standard deviations

Typical Out-of-Control Patterns

  • Point outside control limits
  • Sudden shift in process average
  • Cycles
  • Trends
  • Hugging the center line
  • Hugging the control limits
  • Instability
