  • 1. Quality Basic ToolsSeven Basic QUALITY Tools Aditya@poltekom.ac.id
  • 2. Mind MAP of QUALITYQPE is the TARGET parameterSIX SIGMA is the ASSESMENT methodSEVEN TOOLS is the QUALITY tools Aditya Kurniawan POLITEKNIK KOTA MALANG
  • 3. Seven BASIC tools of quality• Check Sheet• Stratification• Histogram• Pareto Charts• Ishikawa Diagram / Fishbone Diagram• Scatter Diagram• Control Chart Aditya Kurniawan POLITEKNIK KOTA MALANG
  • 4. Check Sheet / Tally sheet Taken From QPE Aditya Kurniawan POLITEKNIK KOTA MALANG
  • 5. Check sheet procedure• Classification: A trait such as a defect or failure mode must be classified into a category.• Location: The physical location of a trait is indicated on a picture of a part or item being evaluated.• Frequency: The presence or absence of a trait or combination of traits is indicated. Also number of occurrences of a trait on a part can be indicated.• Measurement Scale: A measurement scale is divided into intervals, and measurements are indicated by checking an appropriate interval. Aditya Kurniawan POLITEKNIK KOTA MALANG
  • 6. Check sheet- Classification• Classification: A trait such as a defect or failure mode must be classified into a category. Classification of defects/failure must be technically identifiedexample:DimensionMotor speedWheel clearance Aditya Kurniawan POLITEKNIK KOTA MALANG

  • 22. PARETO chartA classification order / prioritizing order – Pareto charts are used to identify and prioritize problems to be solved. – They are actually histograms aided by the 80/20 rule adapted by Joseph Juran. •Remember the 80/20 rule states that approximately 80% of the problems are created by approximately 20% of the causes. Aditya Kurniawan POLITEKNIK KOTA MALANG
