5. © Copyright Protected, Varatech Inc. High cost of poorly manufactured products –$ millions: Recalls, Lawsuits, Brand Destruction –Redesign, Retool, Remanufacture Problems are identified after tools are cut, production is run, and products sold. assembly build variation83% of survey respondents in Quality Magazine say quality related defects are related to assembly build variation issues. 30%-50% of scrap and rework caused by poor tolerance and variation management. Need for Sigmund

6. © Copyright Protected, Varatech Inc. Variation Analysis is very important for: The manufacturability of a proposed design Reducing cost and time Improving quality and preventing defects A manufacturing company’s competitiveness, market- share, bottom-line profitability and survival. Need for Sigmund

7. © Copyright Protected, Varatech Inc. …69% of survey respondents want to invest to improve manufacturing efficiency while 59% will invest to reduce scrap and rework. 83% believe assembly variation issues are responsible for quality related defects …51% of respondents want to reduce costs while 42% want to achieve tighter part quality standards. Statistics from Quality Magazine
