We are in business to make money

We make money by satisfying needs

We are able to satisfy needs by doing

Every need/do pair is an interaction

The aim of customer focus is to improve vital need/do interactions

Repetition of the same action constitutes a process

Improvement our business means improvement of our processes

Customers need products/services on-time, with zero defects, at the lowest cost

Suppliers create processes to generate needed products

As process capability improves, the product quality increases

As quality increases, costs and cycle-time go down

Customer satisfaction must be measured if is to be improved

To improve means we must be able to predict and prevent, not detect and react

Prediction is correlated to certainty

Certainty is dependent upon the measurement of process capability

Process capability is best understood and reported using statistics

Statistics are dependent upon data

Data must be collected in the process according to a plan

Statistics is used to convert raw data into meaningful information

Statistical information is used to report on, improve, and control the process

The basis of statistics is the mean and standard deviation

The mean reports on process centering

The standard deviation reports on process spread

Use of the mean and standard deviation allows the Sigma to be calculated

The Sigma of a process tells us how capable it is

The process Sigma can be used to compare similar or dissimilar processes

Such comparison of processes is called benchmarking

Benchmarking is a tool used to uncover what we do well and not so good

Preemptive action leads to low cost quality solutions

Corrective action leads to high cost solutions

The reduction of defects, cycle-time, and cost leads to customer satisfaction

As customer satisfaction improves, the likelihood of doing business increases

As business increases, we (as individuals) grow and prosper
