Definition:Quality management ensures that an organization, product or service is consistent. It has four main components: Quality planning,
Quality assurance, Quality control and Quality improvement. Quality management is focused not only on product and service quality, but also on the means to achieve it. Quality management, therefore, uses quality assurance and control of processes as well as products to achieve more consistent quality.
The Quality Gurus : - Joseph Juran (1904 - 2008 )
Quality is “uniformity and dependability”
Focus on SPC and statistical tools “14 Points” for management PDCA method
The Quality Gurus : - Joseph Juran (1904 - 2008 ) Quality is “fitness for use” Pareto Principle Cost of Quality General management approach
as well as statistics
Principles:The International Standard for Quality management adopts a number of management principles, that can be used by top management to guide their organizations towards improved performance. Customer focus Leadership Engagement of people Process approach Improvement Evidence based decision makingRelationship management
Cost of quality• Prevention costs
• Appraisal costs
• Internal failure costs
• External failure costs
• Opportunity costs
Methods for Quality ImprovementThere are many methods for quality improvement. These cover product improvement, process improvement and people based improvement. The following list are methods of quality management and techniques that incorporate and drive quality improvement:
ISO 9004:2008 - guidelines for performance improvement. ISO 9001:2015 - a certified quality management system (QMS)
for organizations who want to prove their ability to consistently provide products and services that meet the needs of their customers and other relevant stakeholders.
ISO 15504-4: 2005 - information technology — process assessment — Part 4: Guidance on use for process improvement and process capability determination.
Methods for Quality Improvement QFD - quality function deployment, also known as the house of
quality approach. Kaizen - Japanese for change for the better; the common English
term is continuous improvement. Zero Defect Program - created by NEC Corporation of Japan,
based upon statistical process control and one of the inputs for the inventors of Six Sigma.
Six Sigma - 6σ, Six Sigma combines established methods such as statistical process control, design of experiments and and failure mode and effects analysis (FMEA) in an overall framework.
PDCA - plan, do, check, act cycle for quality control purposes. (Six Sigma's (DMAIC)method (define, measure, analyze, improve, control) may be viewed as a particular implementation of this.)
Methods for Quality Improvement Quality circle - a group (people oriented) approach to improvement. Taguchi methods - statistical oriented methods including quality
robustness, quality loss function, and target specifications. The Toyota Production System - reworked in the west into lean
manufacturing Kansei Engineering - an approach that focuses on capturing customer
emotional feedback about products to drive improvement. TQM - total quality management is a management strategy aimed at
embedding awareness of quality in all organizational processes. First promoted in Japan with the Deming prize which was adopted and adapted in USA as the Malcolm Baldrige National Quality Award and in Europe as the European Foundation for Quality Management award (each with their own variations).
TRIZ - meaning "theory of inventive problem solving"
Methods for Quality Improvement TRIZ - meaning "theory of inventive problem solving" BPR - business process reengineering, a management
approach aiming at optimizing the workflows and processes within an organization
OQRM - Object-oriented Quality and Risk Management, a model for quality and risk management.
Top Down & Bottom Up Approaches - Leadership approaches to change
Six Sigma Quality A philosophy and set of methods companies use to eliminate
defects in their products and processes
Seeks to reduce variation in the processes that lead to product defects
The name “six sigma” refers to the variation that exists within plus or minus six standard deviations of the process outputs
