Lesson 2.1 – Lean Principles
1. One of the most basic things about Lean is the focus on time. Requires a continuous look at ways of
making things not only better, but FASTER. If time is money, then Lean is an effective money maker.
a. Lean is a systematic approach where the goal is to identify and eliminate waste.
b. It looks at the existing system or method of production.
c. It assumes there is already a way of doing things and examines that way – or system – in
detail.
d. While the output of the system may vary, the system should remain constant.
e. In Lean terms, Waste is referred to as Non ‐ Value Added activity
f. Goal: Continuous Improvement.
i. Foundation of Lean
ii. Attack the problem over and over again
iii. Returns generally diminish as areas improve, but the point is to never accept the
2. Five Guiding Principles of Lean
a. Value ‐ specifying exactly what creates value … from the CUSTOMER’S perspective
i. Specify value from the perspective of the customer and ONLY from that perspective
ii. Recognize that only a small fraction of the total time and effort in any organization
actually adds value for the end customer
iii. Clearly defining Value for a specific product or service from the end customer’s
perspective, all the non value activities ‐ or waste ‐ can be targeted for removal
1. Processes have three types of activities
a. Value Added
i. Activity must actually change something about the
product or service (changes form, fit or function)
ii. Customer must be willing to pay for it
iii. Activity is done correctly the first time.
b. Non ‐ Value Added (waste)
c. Non ‐ Value Added but required (things which must be done, but
don’t add value FROM THE CUSTOMER’S PERSPECTIVE i.e. safety)
b. Value Stream ‐ very tedious and intricate task of identifying all steps along process chain
i. Tool allows us to determine which activities are Value Added and which are MUDA,
or Waste
ii. Map out ALL linked actions currently used for transforming inputs to outputs
iii. First step in the improvement process
iv. Creates a picture of the entire value stream from the customer’s perspective and
allows us to see pockets of waste
v. The Value Stream represents the end ‐ to ‐ end process that delivers the value to the
customer
vi. Once you understand what your customer wants the next step is to identify how
you are or are NOT delivering that to them
c. Flow ‐ start making changes to make those processes flow smoothly

i. Smooth movement of products and services along the value stream
ii. Ideally we want things to move continually and steadily throughout the process
iii. Perform just one process activity on each piece in a group or batch (of 5, or 10, or
20, etc) before sending it to the next step
iv. Make the value ‐ creating steps occur in tight sequence so the product will flow
smoothly toward the customer
v. Create this Flow by eliminating Waste
d. Pull ‐
