History of the New Seven Q.C. Tools
Committee of J.U.S.E. - 1972
Aim was to develop more QC
techniques with design approach
Work in conjunction with original Basic
Seven Tools
New set of methods (N7) - 1977
Slide 1 0f 2
History of the New Seven Q.C. Tools
Developed to organize verbal data diagrammatically.
Basic 7 tools effective for data analysis, process control, and quality improvement (numerical data)
Used together increases TQM effectiveness
