Once upon a time, companies were used to contributing to good causes by donating part of their profits. This initiative had a twofold benefit: On one side, it was a great opportunity to gain media exposure and brand awareness and improve the donor’s positioning within its target group. On the other side, the company could deduct the donation for fiscal benefit purposes. As social and environmental pressure built up, new groups of interest started to generate concepts like sustainable development goals (SDGs) or environmental, social and corporate governance (ESG) models as an attempt to standardize these practices as a management model and make those initiatives become an operational issue. And thankfully, I think they are largely succeeding. More and more companies of all sizes are treating social and environmental impact as business concerns

The Key Quality Problem
Trang 7• The Lemon Laws
• What is a ‘lemon’? The definition of a ‘lemon’ is a car (often new) that is found to be defective only after its purchase Any motor vehicle with numerous, severe defects that reoccur after multiple repair attempts is such and the term ‘lemon’ can also extend to any product with flaws too great or severe to serve its purpose
Consumer experiences Ms Cicchini purchased a brand new Alfa Romeo 147 in 2009 During the three year manufacturer’s
warranty period the vehicle had been back to the dealership approximately twenty times and had spent over 160 days in the workshop Ms Cicchini had made numerous calls and had sent hundreds of emails to the dealership She had even sent emails to the importer, manufacturer in Italy and the International CEO of Fiat Chrysler Automobiles in attempts to get a satisfactory
resolution After receiving an extended one year manufacturer’s

• The Quality Movement arose in the 1930’s
•Quality as
• ‘made to specifications’
• ‘deliver on the promise
• ‘doing it right the first time’
•Often confused with being the best, most expensive
• The Rolls Royce story is essentially one of understanding quality at every level of the process
– And delivering a product that is precise in every way
Trang 24W Edwards Deming’s Quality Management
Philosophy
• Focuses on improving product and service quality by reducing
variability in goods and services design
• Higher quality leads to higher productivity and lower costs
Leads to improved market share and long-term competitive strength
• Deming cycle - Plan, do, study, and act (PDSA)

• within a familiar cultural system
• Advocated the use of
• quality cost measurement
• Focused on elimination of defects
• using statistical tools for analysis
Trang 28Crosby’s Absolutes of Quality Management
• Quality means conformance to requirements, not elegance
• There is no such thing as a quality problem
• Doing the job right the first time is always cheaper
• Only performance measurement
• is the cost of quality,
• which is the expense of non-conformance
• Only performance standard is Zero Defects
Trang 30Formally Defined: Quality Management

• with appropriate levels of quality
• to meet the needs of customers
• Deals with issues relating to how goods and services
• are designed,
• created, and
• delivered to meet customer expectations

Trang 36Six Sigma, Part 1
Business improvement approach
• Seeks to find and eliminate causes of defects and errors in manufacturing and service processes
• Focuses on outputs that are critical to customers
Results in a clear financial return for the organization
Trang 37Motorola, Six Sigma, 3.4 defects per million.
• 1986
Trang 38Six Sigma, Part 2
Level of capability indicates a level of near-zero defects
• Defect: Mistake or error that is passed on to the customer
• Unit of work: Output of a process or an individual process step
Defects per unit (DPU) = No of defects discovered / No of units produced
Trang 39Six Sigma, Part 3
• Quantifies quality performance by defects per million opportunities
(dpmo)
dpmo = No of defects discovered /Error opportunities
• In service applications, analogous to dpmo, the term errors per
million opportunities (epmo) is used
Trang 40Key Concepts of Implementing Six Sigma
• Emphasizing dpmo or epmo as a standard metric that can be applied
to all parts of an organization
• Providing extensive training followed by project team deployment
• Focusing on corporate sponsors responsible for supporting team
activities
Trang 41Key Concepts of Implementing Six Sigma
• Creating highly qualified process improvement experts
• Ensuring that appropriate metrics are identified early in the process
and that they focus on business results
• Setting stretch objectives for improvement
