    Absolutely!!
    What a great opportunity – you  have all these clearly identifiable variables affecting the process – all of which need to be controlled, and most of which are understood already.  True the list of variables could be lengthy, and doing a DOE a nightmare, but I would have said that this was an ideal opportunity for SS, and also could have a significant impact on customer satisfaction and the oft-mentioned bottom line.
    A Pareto of the most significant problems currently encountered would give a starting point for activity.  Make sure the project (if any) is very carefully defined at the start – otherwise there will be a potantial for ‘Project creep’ and it could turn into a real mare.
    regards

    Yes………….Six Sigma can help.
    I love to work in a company that has high defect level like this.
    There is much room that can be improved. I can find projects easiliy.
    Six Sigma can be applied to the process like investment casting.
    My former corporate had a project : “Reduce Core Break”
    At my current company, we have a casting shop (but not investment casting).
    We have a project : “Reduce Casting Defects (porosity)”.
     These are what I have seen with my eyes.
    Believe me. Six Sigma can help.
    Hope this helps.

    Craig Sherwood,
    Six Sigma is highly suitable to manufacturing process improvement. But equally can be applied in any sector of business eg Government department, non maufacturing serivce industries, eg maybe a grocery industry or banks, Call Centers, Railways, etc.
    Basic requirement is, to have Process and Continuous or Discrete Data Sets.
    With regards to: how and where and what. A simplfied approach will be – to explain the point:
    Define a process – here you need to understand the customers, inputs and outputs, Cost of poor quality (COPQ),  Few questions 1. What is “Crtical to Process (CTP), 2. What is “Critical to Quality” (CTQ). 3.What is “Critical to Cost” (CTC). 4. What is “Critical to Delivery” (CTD). 5. What is Critical to Satisfaction (CTS). Produce Process Map where the defects are.
    Iam of the school of “DMAIC” – therefore, as in the Ist point, one needs to define the process, understood the dis-satisfaction, cost of poor quality etc – this list is given above.
    Measure, Analysis, Improve and Control.
    You will definetely need to listen to your both internal and external customer (VOC). Leadership is important. Low hang fruit improvement, can get the organisation believe what Six Sigma can do, for them and business.
    Now you are doing in essence a six sigma approach to process improvement.
    Six Sigma can not be explain in one feedback reply. Therefore, if you need any help contact to discuss options – will be able to guide you. Good Luck
    Ali
