Profound Knowledge
• Appreciation for a system
• Understanding of variation
• Theory of knowledge– experience– theory
• Psychology
Systems
• Most organizational processes are cross-functional
• Parts of a system must work together
• Every system must have a purpose
• Management must optimize the system as a whole
Variation
• Many sources of uncontrollable variation exist in any process
• Excessive variation results in product failures, unhappy customers, and unnecessary costs
• Statistical methods can be used to identify and quantify variation to help understand it and lead to improvements
Theory of Knowledge
• Knowledge is not possible without theory
• Experience alone does not establish a theory, it only describes
• Theory shows cause-and-effect relationships that can be used for prediction
Psychology
• People are motivated intrinsically and extrinsically; intrinsic motivation is the most powerful
• Fear is demotivating
• Managers should develop pride and joy in work

Ishikawa
• Quality begins & ends with education.• The first step in quality is to know the
requirements of the customer.• The ideal state of quality control occurs when
inspection is no longer necessary.• Remove the root cause, not the symptoms.• Quality control is the responsibility of all workers
and all divisions.• Do not confuse the means with the objectives.
Ishikawa
• Put quality first and set your sights on long-term profits.
• Marketing is the entrance and exit of quality.• Top management must not show anger
when facts are presented by subordinates.• 95% of problems in a company can be
solved with simple tools for analysis and problem-solving.
• Data without dispersion information (variability) is false data.
