1 PDCA CYCLE

2 7 Basic Tools  Flow Chart  Check Sheet  Histogram  Pareto Chart  Scatter Diagram  Cause & Effect Diagram  Run Chart/Statistical Process Control

3 Flow Charts are used to... document a process improve understanding reveal differences in methods uncover non-value added activities

4 Flow Chart Example: Self-Serve Gas Before Improvement Drive in check price self serve? to pump shut off engine walk to pay station yes no check card transmitapproved? turn on pump yes no back to car pump gas walk to booth wait employee totals charges check accuracy prepare receipt sign copy copy to file copy to wallet return to car on the road again

5 Flow Chart Example: Self-Serve Gas After Improvement Drive in check price self-serve? no yes go to pump shut off engine insert card in pump check credit card wait approved? no yes wait for receipt store in system copy to wallet on the road again pump gas

6 CHECK SHEETS Data collection & analysis Contents mixed Poor taste Low temperature Utensils dirty Price issue Other

7 Histograms Graphical descriptive statistics (mean and standard deviation) Bell-Shaped Uniform Bimodal

8 Pareto Charts Similar to a histogram, used to find “most popular” category Based upon the Pareto principle...

9 Basic Pareto Diagram Complaints courtesy of my Spring OPC class

10 Alternate Pareto Diagram Complaints courtesy of my Spring OPC class

11 Scatter Diagram Exam Score Homework Problems Class 1 Class 2 Graphical descriptive statistics (correlation)

12 Cause & Effect Diagrams Also known as fishbone diagrams or Ishikawa diagrams, after their creator Kaoru Ishikawa In general, used to find and cure causes (NOT symptoms) of problems

13 Cause & Effect Example LATE PIZZA DELIVERY FRIDAY & SATURDAY MANPOWERMETHODS MATERIALSMACHINES Drivers lost Chef late Lack of ingredients Small ovens Large order snafus Bad cars Poor dispatching

14 Run Chart Graphical descriptive statistics (trend)

15 Statistical Process Control Finds “special” variation General form of limits Center line = Average * Not the variance
