                 Why The Need For Lean in the
                 Footwear Industry
                 •   Historically, the footwear industry has operated as a push system
                     focused on economies of scale, with large batches and long
                     assembly lines.
                      – Labor-intensive manufacturing processes require
                         manufacturing in low-cost countries.
                      – Focus on departmental efficiencies.

                 •   Customers’ increasing demands for a greater variety, more
                     frequent deliveries, and smaller order quantities; all at a lower
                     cost.

                 •   Ongoing need to demonstrate leadership in corporate
                     responsibility:
So what to do?        – Respect for workers

best.                 – Sustainability (elimination of waste)

                 •   Industry and shareholder pressure to improve margins and
                     reduce cycle time.


                                                                                         3
The Approach to Lean
   Start with a simple definition of Lean Thinking

        Deliver the most value

             From your customer’s perspective

                 While consuming the fewest resources



    Key Insights
    •   Focus on each product and its value stream rather than
        organizations, functions, assets, and technologies.

    •   Ask which activities are waste and which create value.

    •   Enhance the value and eliminate the waste to optimize
        the whole.

    “All we are doing is looking at the time line from the moment the customer gives us
    an order to the point when we collect the cash. And we are reducing that time line by
    removing the non-value-added wastes.”                     Taiichi Ohno,1988

2.   Each team pick a topic from work or from school

3.   For each topic, work through as much of the A-3
     format as you can. Defining the business problem is
     a good place to start.

4.   Use visuals if possible. Use 5 why analysis to
     understand root cause. Note where you are making
     assumptions vs using facts.

5.   Brainstorm recommendations that address root
     cause.

6.   Summarize your ideas in the A-3 format.

Five Suggestions for You Today

1.   Learn the System, including the dirty details.

2.   Choose a place to begin your own project. Implement it
     as an integrated system.

3.   Use the Plan Vs. Actual to lead implementations of your
     Future States.

4.   Learn Standardized Work (“SWS”). Implement it by
     focusing on the operator. Eliminate waste in each
     operator’s job!

5.   Ensure clear ownership at the right level(s).

Closing Thoughts

“From the end customer’s standpoint none of the information
   processing steps creates any value. To test this assertion,
   just ask yourself whether you would be less satisfied with a
   product if it could be ordered and delivered to you with no
   management of production and logistics information.

Obviously you would not be less satisfied. Indeed you would
  be more satisfied if the cost savings from eliminating
  information acquisition and management could be passed
  along to you.

Yet in the modern era of automated information management,
   most managers have implicitly accepted the notion that
   information is good, more information is better, and all
   possible information is best. In fact, information for control
   of operations is necessary waste. Managers ought to be
   minimizing the need for it rather than maximizing its
   availability.”
