9.5 Quality Control Techniques

QFD (Quality Function Deployment)

  • focusing and thorough planning of quality expectations
    (using the "House of Quality" model),
  • planning schemes to translate market / customer
    expectations into action for production that is as free from failure as possible, in four phases:
    - product strategy,
    - product specification,
    - process specification and
    - process protection.

DOE (Design of Experiments)

  • statistical experiment planning for the systematic and efficient accumulation of information for continuous quality improvement. For this purpose, methods such as
    - Taguchi,
    - Shainin and
    - factor experiment plans are applied.

FMEA (Failure Mode and Effects Analysis)

  • the analysis of failure modes and effects, or, more precisely: detection and neutralisation of sources of error.
  • The most well-known/most widely used applications are
    - development FMEA and
    - process FMEA.

SPC (Statistical Process Control)

  • Statistical process regulation using quality rule cards and
  • systematic improvement of processes through intervention when process parameter limits are exceeded. This includes the capability testing of:
    - measuring instruments and
    - equipment.

Poka Yoke

  • Avoiding errors in processes through the provision of specified routines. This means creating an attitude and preventing errors in the process or on the product that occur as a result of human error.
