Why teach me this stuff l.jpg
Why Teach Me This Stuff?

  • Culture is common thinking.

  • Thinking drives behavior.

  • Behavior drives results.

  • Results create opportunities and security.

The Lean Six Sigma curriculum combines the discipline and analytical tools of Six Sigma with the time-based focus of Lean. Our goal is to build and enhance skills among employees that can improve quality and strengthen management practices across HBD.

  • The tools and methodologies in Lean Six Sigma are useful not only in LSS projects, but in everyday tasks. These include:

    • Understanding Customer and Stakeholder Needs

    • Identifying, Analyzing and Presenting Key Business Information

    • Brainstorming on, Deciding upon, and Solving Complex Issues

    • Revising and Simplifying Production-Related Processes

    • Streamlining Administrative Processes and Support Tasks

    • Understanding Variation

    • Managing Cross-Functional Projects

  • The more you understand what these tools are and the underlying philosophy behind them, the better you will be as an active team member in future projects.

What is lean six sigma for hbd lean six sigma profit power l.jpg
What is Lean Six Sigma?For HBD, Lean + Six Sigma = Profit Power!

Per-Unit Profit = Per-Unit Price – Per-Unit Cost;

Net Profit = Sales – Product Costs – Overhead Expenses

Lean Six Sigma offers you the power to

transform operations into flexible, efficient plants

needed to profitably survive and thrive

in a competitive business landscape.

Key aspects of lean l.jpg
Key Aspects of Lean

  • Lean is Not New

    • Popularized by Toyota more than 30 years ago.

    • Many of its tools and concepts have been around for decades.

  • Lean is Both Methodology and Philosophy

    • Lean aims to eliminate ‘waste’(in Japanese, “muda”) in every area of a business, including production, customer relations, product design, supplier networks, and factory and business administration.

    • Its goal is to incorporate less effort, less inventory, less time to develop products, and less space in order to become highly responsive to actual customer demand and to produce top-quality product in the most timely, efficient and economical manner possible.

  • Lean Focuses on Customer-Defined Value

    • A process step ‘adds value’ if the activity adds form, fit or function to the product that is desired by the customer, and the customer is willing to pay you to conduct that activity.

Yellow Belt Training

Key aspects of lean con t l.jpg
Key Aspects of Lean, con’t

  • Toyota Defines Seven Key Types of Muda (Waste)

    • Overproduction: Producing more than demanded or before it is needed, e.g., stored materials or inventories.

    • Inventory or Work-in-Process (WIP): Material between operations due to large lot sizes or long process cycle times.

    • Transportation: Material movements, by definition, add no value to products, as they do not affect form, fit or function.

    • Processing Waste: Unnecessary or inefficient process steps simply add cost and time.

    • Motion: Effort to move workers and machinery or to transport materials adds cost and delay.

    • Waiting: Long changeover times, slow processing times, and materials handling tasks limit opportunities to make on-time deliveries.

    • Defective Products: Items that fail to meet customer specifications are pure waste, e.g., returns, rework, scrap, and warranty costs.

Key aspects of six sigma l.jpg
Key Aspects of Six Sigma

  • Six Sigma is Not New

    • In existence for more than 20 years; at HBD since 2002.

    • Many of its tools and concepts have been around for decades.

    • Six Sigma packages the tools and concepts into a clear and systematic roadmap for process improvement.

  • Six Sigma is a Methodology

    • The ‘DMAIC’ problem-solving methodology is a disciplined thought process and tool guide used to solve business issues.

    • Define / Measure / Analyze / Improve / Control / (and Verify).

  • Variation is Bad (‘Evil’)

    • For most processes, a repeatable and predictable result is crucial.

    • Six Sigma is designed to identify the key sources of variation and drive them out of the process, by understanding the key inputs, processes and outputs of business activities. “Fix the process to get good results.”

Yellow Belt Training

Key aspects of six sigma con t l.jpg
Key Aspects of Six Sigma, con’t

  • Six Sigma has a Customer Focus

    • Processes and problems must be viewed from the customer’s perspective.

    • Internal customers (i.e., downstream departments) can be just as important as external customers (i.e., those who pay the bills).

  • Six Sigma is Not Just for Manufacturing or Large Businesses

    • Success can be found in all types of companies and all kinds of processes – including at HBD.

  • AND…Six Sigma and Lean are Not Mutually Exclusive

    • Without a basic understanding of both methodologies, you risk trying to ‘use a screwdriver to drive a nail.’

    • Ask, ‘What tool or technique is most useful to help solve my problem?’

  • Projects have successfully touched both production and back-office (paperwork) processes

    • 112 LSS projects initiated (as of 7/31/07) plus 29 documented kaizens

    • Over $6.65MM in hard-dollar and soft-dollar savings, cost avoidance, new-revenue opportunities, and working capital improvements

  • LSS represents one key tool for on-going improvement efforts
