Focus on prevention rather than detection

Fix the root cause rather than the symptom

Use the 80-20 rule to focus attention on what is the most important

The person within 10 sq. ft of the job being done is the expert

Computerizing a bad system doesn’t make it better

Decisions should be made at the lowest level

Increasing the variability causes the performance of a system to decline 

Reward extra achievement, not what’s expected

Quality is everyone’s responsibility

Improvement is never enough

Checks and controls points should be reduced to one location

Synchronize Movements

Certification should replace inspection

You need to consider the time value of money in making investment decisions

Breakdown large projects into manageable parts

Safety improvements nearly always result in production improvements

Mistakes are a good source of process knowledge if used properly

There is an optimal way to allocate resources

Insight is more important than information

Use expected values when outcomes are uncertain

Simple solutions are generally the best

To increase capacity, look for bottlenecks

Quality is not just a production issue.

A change in design is 100x more effective than a change in production

Look for hidden costs in additional to the more apparent costs

Any constraint on a system has cost

Every investment has an opportunity cost

Money already spend should not enter into an investment decision

Because of variability in a system, you can never get 100% utilization

Design the product and process to fit the human body

Ergonomically designed work centers are more productive

Inspection does not add any value to the product

In order to reduce quality costs, you have to control process variability

Hidden costs of quality are far greater than the reported costs

In order to be successful with advanced manufacturing systems, system variability needs eliminated

Lean manufacturing systems require high-levels of process reliability

Every step in the process should be clearly value-added to at least one customer

Work-in-process should be minimized

Work smarter, not harder

The process should have multiple versions for different types of customers

Technology should be used to replace repetitive manual tasks

No activity should be done that costs more than its return

Training should be continuous and focused on learning best practices
