    Six Sigma

    A rigorous, focused and highly

    effective implementation of provenquality principles and techniques

    that aims for virtually error free

    business performance.

    Further Defined?

    A statistical approach to problem solving

    A management culture

    A way of thinking

    A set of new behaviors

    Synonymous with:

    Improving quality

    Reducing cost

    Improving customer loyalty/customersatisfaction

    Achieving bottom-line results

    The Six Sigma Methodology

    Six Sigma is a structured, DATA DRIVENmanagement methodology that can be applied toall aspects of business.

    The application of this methodology eliminates theuse of opinion - I think andI feel - and drivesthe organization to a more scientific means ofdecision-making.

    Six Sigma is nota statistics program. Statistics areused solely as tools for interpretation andclarification of data.

    The DMAIC Model

    At the heart of Six Sigma is a systematic method for

    analyzing and improving business processes called

    DMAIC. The model includesfive elements:

    Define opportunities

    Measure performance

    Analyze opportunityImprove performance

    Control performance

    Is the current state as good as the

    process can do?

    Who will help make the changes?

    fail?

    What major obstacles do I face in

    completing this project?

    What is the work breakdown

    structure?

    What specific activities are necessary

    to meet the project's goals?

    How will I re -integrate the various

    subprojects?

    Control

    During the project, how will I control

    risk, quality, cost, schedule, scope,

    and changes to the plan?

    What types of progress reports shouldI create?

    How will I assure that the business

    goals of the project were

    accomplished?

    How will I keep the gains made?

    The DMADV Model

    Systematic method for creating or reinventingbusiness processes is DMADV. Typically use:

    New designs

    Existing product or process was optimized

    Tollgate Reviews

    Another component of DMADV and DMAIC thathelps to ensure that the requirements of allcustomers are met is the tollgate review.

    At the end of each phase of the DMADV or

    DMAIC process, all stakeholders meet to ensurethat:

    1) The requirements have not changed

    2) What is being designed still addresses the requirements.

    3) The measurements really address the requirements.

    The tollgate review is an excellent tool for keeping allcustomers on the same page, involved in the process andcommunicating requirements.

    Six Sigma Pitfalls

    1. Companies that adopt Six Sigma as there

    quality improvement strategy believe thatevery problem should be resolved by a SixSigma project team.

    2. Insufficient cross-functional team

    representation.3. Inadequate participation by executive

    management.

    4. Initially a part-time BB requires significant

    start-up time to achieve success and mayconflict with other duties.

    5. Unrealistic Goals. 3.4 parts per million onEvery Process, Excessive Time and Cost to

    Gather Performance Data, etc.
