What is Quality? (1)

FEDEX - “Performance to the standard expected by the customer”

General Services Administration - “Meeting the customer’s need the first time and every time”

BOEING - “Providing customers with products and services that consistently meet their needs and expectations.

US Department of Defense - “Doing the right thing right the first time, always striving for improvement, and always satisfying the customer”.

Quality can be defined in terms of the agent. Who is the judge of quality?

What is Quality? (2)

Quality involves meeting or exceeding customer expectations.

Quality applies to products, services, people, processes, and environments.

Quality is an ever-changing state (i.e., what is considered quality today may not be good enough to be considered quality tomorrow).

Quality is a dynamic state associated with products, services, people, processes and environments that

meets or exceeds expectations.

Two Views of Quality (1)

Customer focus

Traditional View: Total Quality View

• Process performance = defective parts per hundred produced.

• Focused on after-the-fact inspections of products.

• Employees are passive workers who followed orders.

• One improvement per year per employee

• Focus on short term profits

• Process performance = defective parts per million produced.

• Continuous improvement of products, processes and people.

• Employees are empowered to think and make recommendations.

• At least 10 improvements per employee per year

• Focus on long term profits and continual improvement.

Customer focus

Traditional View Total Quality View

Productivity and quality are always in conflict. You cannot have both.

Productivity versus qualityLasting productivity gains are made only as a result of quality improvements.

How quality is definedMeeting customer specifications.

Satisfying customer needs and exceeding customer expectations.

How quality is measured

Establishing an acceptable level of nonconformance and measuring against the bench mark.

Establishing high-performance bench marks for customer satisfaction and then continually improving performance.

Customer focus


Quality is inspected into the product.

How quality is achievedQuality is determined by product design and achieved by effective control techniques.

Attitude towards defectsDefects are an expected part of producing a product.

Defects are to be prevented using effective control systems.

Quality as a function

Quality is a separate function. Quality should be fully integrated throughout the organization, i.e. it should be every body’s responsibility.

Obsession with Quality

All personnel at all levels approach all aspects of the job from the perspective of “How can we do this better?”.

“Good enough” is never good enough.

Scientific Approach

Hard data are used in establishing benchmarks, monitoring performance, and making improvements.

Decision making and problem solving is based on scientific principals.

Long-term Commitment

Quality improvement is NOT another management innovation but a whole NEW way of doing business that requires an entirely new corporate culture.

Teamwork

Internal competitiveness vs. External competitiveness

Continual Process Improvement

Continually improve systems (environments) where products are developed and services are delivered by people.

Education and Training

Best way to improve people on a continual basis.

Train hardworking people “How to work smart?”

Freedom through Control

Involving and empowering employees to simultaneously bring more minds to bear on the decision-making process and increase the ownership employees feel about decisions that are made.

Well-planned and carried-out controls (not loss of management control).

Unity of Purpose

Internal politics have no place in a total quality organization, rather collaboration is the norm.

Unity of purpose has nothing to do with Labor Unions.

Employee Involvement and Empowerment Basis for involving employees: 1. to increase the

likelihood of a good decision or a better plan; 2. to promote ownership of decisions by involving the people who will have to implement them.

Empowerment means not just involving people but involving them in ways that give them a real voice.

The Deming Cycle (1)

1. Conduct consumer research and use it in planning the product (PLAN).

2. Produce the product (DO).

3. Check the product to make sure it was produced in attendance with the plan (CHECK).

4. Market the product (ACT).

5. Analyze how the product is received in the market in terms of quality, cost and other criteria (ANALYZE)

Six Sigma Concept (1)

A Six-step Protocol for Process Improvement

1. Identify the product characteristics wanted by the customers.

2. Classify the characteristics in terms of their criticality.

3. Determine if the classified characteristics are controlled by part and/or process.

4. Determine the maximum allowable tolerance for each classified characteristic.

5. Determine the process variation for each classified characteristic.

6. Change the design of the product, process, or both to achieve a Six Sigma processes performance.

What is Six Sigma?

Six Sigma is an extension of total quality management which has the aim of taking process and product quality to levels where all customer requirements are met.

How is Six Sigma Achieved?

By improving process performance.

Or, Without improving the process at all if the specifications describing acceptable product can be loosened enough to correspond to the original process’s ± 6 sigma points.
