5 core principles & 8 waste (muda)

Value

defined by the customer, created by the producer

Value Stream

Specific actions required to create a specific product

Flow

removing stoppages, back flows, and scraps for continuous production

Pull

A system where nothing is produced until the customer downstream signals a need, allowing the customer to “pull” the product or service rather than having it “pushed” onto them.

Perfection

The ongoing pursuit of continuously reducing waste, effort, time, space, cost, and mistakes so the product better matches what the customer truly wants.

Defects (inspection, sorting, replacement, repair, scrap)

Efforts caused by rework, scrap, and incorrect information.

Overproduction

Production that is more than needed or before it is needed.

Waiting (delays, idle)

Wasted time waiting for the next step in a process.

Non-Utilized Talent

Underutilizing people’s talents, skills, & knowledge.

Transportation

Unnecessary movements of products & materials (movement from area to area)

Inventory (inventory, raw material, work-in-progress, finished goods)

Excess products and materials not being processed.

Motion (inefficiencies)

Unnecessary movements by people (does not add value to the product) movement within the area

Excess Processing (extra processing)

More work or higher quality than is required by the customer
