“The Complete Lean Enterprise” workbook
due out this month from Productivity Press
Patterned after “Learning to See” but
includes:
distinct business issues
waste in office settings
new office metrics
functional area "lean thinking."
Lean ThinkingLean Thinking
Fundamental Objective: To create the most
value while consuming the fewest resources.
Define value from the customer’s perspective.
Identify which process steps create value and
which are only waste (muda).
Work to eliminate the root causes of the waste
and allow for continuous flow of work and tasks.
Why Go Beyond Plant LevelWhy Go Beyond Plant Level
Improvements?Improvements?
Administrative activities are often a major
percentage of the total throughput time
Goal: 400% improvement in productivity
over 10 years
Modest opportunities on the plant floor;
untapped opportunities off the plant floor
How Does “Off the Plant Floor” Differ?How Does “Off the Plant Floor” Differ?
Many functions are not well documented
Many functions support several services
without clear boundaries
Harder to identify customer, product and
customer value
Waste in administrative processes is much
harder to see - more entrenched and hidden
If We Could Just Get to A PointIf We Could Just Get to A Point
Where We Have….Where We Have….
Activities aligned with our business
strategy
Efforts focused on NET improvements
for the company
Metrics supportive of fundamental
change
Simple, constant communication of

Michigan Steel Case StudyMichigan Steel Case Study
Michigan Steel processes and distributes steel coils and sheets to customers within Southern Michigan.
One of its customers, Acme Stamping, recently did some “lean thinking” and has asked Michigan Steel
to increase the deliveries of steel from twice a week (Tuesdays and Thursdays) to once a day. This
case study deals with the order entry and processing of information before any shop order scheduling
and delivery takes place.
Order Processing
Michigan Steel’s current order processing includes receiving a fax on a weekly basis and processing it within
an order entry process. Acme is asking them to receive a daily phone order and deliver the order the
following day.
Michigan Steel wants to have only one way to process orders for all customers, as opposed to a special one
for Acme Stamping. And, it must process orders quickly to ship steel out the next day. They receive about
46 orders per day from all of their customers. The front office is paid to work an 8 hour day and is allowed
two 10 minute breaks. Lunch is unpaid. The order entry function is as follows:
Orders are received by customer service by walking to the fax machine and returning with the fax to the
work station. The faxed orders are batched and sent to accounting to check the credit through the finance
system. Once the credit is approved, the orders are then sent back to customer service where the order
information is reviewed and entered into the MRP system. The MRP system determines the shipping
requirements for the orders (i.e., what goes on Tuesday vs. Thursday), and flags any partial loads or over
loads. A report of these shipping problems is generated and printed in Customer Service. Customer
Service then reconciles the report against the customer needs. The customer then receives a confirmation
phone call, and the order is then finalized for scheduling by Customer Service in the MRP system. The
order is then ready to be scheduled by Production Control.

Focused on:
Creating a flexible, reactive system that
quickly adapts to changing customer needs
Eliminating waste
Minimizing handoffs and silos
Triggering resources only when needed
Future State QuestionsFuture State Questions
What does the customer really need?
How often will we check our performance to customer
needs?
Which steps create value and which are waste?
How can we flow work with fewer interruptions?
How do we control work between interruptions?
Is there an opportunity to balance the work load and/or
different activities? How will work be prioritized?
What process improvements will be necessary?
What Does the Customer ReallyWhat Does the Customer Really
Need?Need?
What “service level” does the customer
need?
Desired response or turnaround time
Expected quality level of the output
What is the demand for the process?
Expected demand rate
Expected variation in the demand rate
Required resources to meet demand rate(s)
How Often Will We CheckHow Often Will We Check
Performance?Performance?
At what frequency will the system be
reviewed to verify it is satisfying customer
needs and the desired cycle time or service
level?
Example: Six Sales Orders an hour will be processed, with
all orders processed within 1 hour of receipt.
How will we check the progress?
Example: A visual means to determine the “age” of an order
will be provided.
Value Stream Mapping in the Office
What Steps Create Value and WhichWhat Steps Create Value and Which
are Waste?are Waste?
Challenge every step – ask the
following:
What is really needed by the customer?
Why are the current steps performed?
What can be done differently or not at all?
Is the order of steps creating waste? Where
should decisions be made?
What assumptions underlie the current process?
Are existing controls and administrative guidelines
appropriate?
What knowledge and skills are truly required to
perform the step(s)?

Does the “mix” (e.g. order type) impact
the ability of the system to flow, or
impact the responsiveness of particular
steps in any way?
Example: Rush vs. Standard Orders
Does the “volume” (e.g. demand
variation) impact the system in any
way?

  • 20. Michigan Steel Case StudyMichigan Steel Case Study Michigan Steel processes and distributes steel coils and sheets to customers within Southern Michigan. One of its customers, Acme Stamping, recently did some “lean thinking” and has asked Michigan Steel to increase the deliveries of steel from twice a week (Tuesdays and Thursdays) to once a day. This case study deals with the order entry and processing of information before any shop order scheduling and delivery takes place. Order Processing Michigan Steel’s current order processing includes receiving a fax on a weekly basis and processing it within an order entry process. Acme is asking them to receive a daily phone order and deliver the order the following day. Michigan Steel wants to have only one way to process orders for all customers, as opposed to a special one for Acme Stamping. And, it must process orders quickly to ship steel out the next day. They receive about 46 orders per day from all of their customers. The front office is paid to work an 8 hour day and is allowed two 10 minute breaks. Lunch is unpaid. The order entry function is as follows: Orders are received by customer service by walking to the fax machine and returning with the fax to the work station. The faxed orders are batched and sent to accounting to check the credit through the finance system. Once the credit is approved, the orders are then sent back to customer service where the order information is reviewed and entered into the MRP system. The MRP system determines the shipping requirements for the orders (i.e., what goes on Tuesday vs. Thursday), and flags any partial loads or over loads. A report of these shipping problems is generated and printed in Customer Service. Customer Service then reconciles the report against the customer needs. The customer then receives a confirmation phone call, and the order is then finalized for scheduling by Customer Service in the MRP system. The order is then ready to be scheduled by Production Control.

  • 27. Future State QuestionsFuture State Questions What does the customer really need? How often will we check our performance to customer needs? Which steps create value and which are waste? How can we flow work with fewer interruptions? How do we control work between interruptions? Is there an opportunity to balance the work load and/or different activities? How will work be prioritized? What process improvements will be necessary?

Expected demand rate Expected variation in the demand rate Required resources to meet demand rate(s)
  • 29. How Often Will We CheckHow Often Will We Check Performance?Performance? At what frequency will the system be reviewed to verify it is satisfying customer needs and the desired cycle time or service level? Example: Six Sales Orders an hour will be processed, with all orders processed within 1 hour of receipt. How will we check the progress? Example: A visual means to determine the “age” of an order will be provided.
  • 31. What Steps Create Value and WhichWhat Steps Create Value and Which are Waste?are Waste? Challenge every step – ask the following: What is really needed by the customer? Why are the current steps performed? What can be done differently or not at all? Is the order of steps creating waste? Where should decisions be made? What assumptions underlie the current process? Are existing controls and administrative guidelines appropriate? What knowledge and skills are truly required to perform the step(s)?
