    Dear Friends,
    I was told by one of my friends that six sigma should not be applied or started for a known problem / solution.
    I would like to get clarifications from your end.
    1. TO WHICH TYPE OF PROBLEM SIX SIGMA TOOL SHOULD BE APPLIED
    2. ANY RESTRICTION IN CHOOSING THE TYPE OF PROBLEM OR PROJECT
    3. HOW MUCH TIME WILL IT TAKE TO COMPLETE A SIX SIGMA PROJECT (I HAVE GOT ENOUGH DATA FOR THE PROJECT TO WHICH I AM GOING TO APPLY SIX SIGMA)
    THANKS & REGARDS

    Dear Ram,
     
    It is true that if the solution is already known, it is not advisable to use Six Sigma.
    SS is not any tool/accessory to deploy an existing solution. Rather it is a scientific approach to achieve process improvement and efficiency to help boost the organizational profitability and ensure customer satisfaction. In this approach nothing is assumed and root causes of undesired output are determined to arrive at the best possible solution.
     
    Regarding your questions:

    Type of Problem: Where the solution is Unknown. Or where N number of solutions could be attempted, but we want to logically examine our current situation to choose the best fit solution and its deployment.
    Restrictions: If the improvement sought moves out of the SMART range, it is a restriction. SMART – Specific, Measurable, Achievable, Realistic & Time-Bound. What you want to improve must be specific and realistic enough so that it can be achieved in a specified time frame; and the improvement must be measurable (no guess-timates).
    Time: Generally a period of 6 months is allotted for projects. Sometimes a project could be over in 4 months or could even take a few extra months. So you could target 6 months. If you complete earlier than that, no harm done as you can further tweak results.

    Hope this helps.
     
    Another thing: I am intrigued how you think you have ‘enough’ data even before you have started a project? How sufficient your existing data is, will only be determined once you have reached the ‘Analyze’ phase, and not before the ‘Define’ phase has even started.
