1. 1 Frank Matejcik SD School of Mines & Technology Sampling Procedures for Extending the Use of the Fishbone Diagram JOINT STATISTICAL MEETINGS Salt Lake City July, 29 2007 Frank Matejcik

2. 2 Frank Matejcik SD School of Mines & Technology Presentation Overview Fishbone diagram; its current procedure Value and use of the extension State of the art of capture-recapture methods Pareto follow up and qualitative, quantitative research

3. 3 Frank Matejcik SD School of Mines & Technology Ishikawa Diagram Cause & Effect, Fishbone

4. 4 Frank Matejcik SD School of Mines & Technology Current Procedure and Current Status One Group Activity (Stop on agreement) Meeting management tool Assumption: everyone concerned can be accessed, No need for sampling Sometimes vote afterward (Swanson) Part of 6  other quality efforts since 1960’s MS Visio, Dia (GNU), Open Office Draw

5. 5 Frank Matejcik SD School of Mines & Technology Value of the extension More multi-site & multinational operations For a larger scale problem (everyone is inconvenient) a value for sampling Measure completeness of task Individual contributions noted Procedure allows the individual to be considered as the sampling unit Alternative methods don’t address completeness

6. 6 Frank Matejcik SD School of Mines & Technology Use of Check Sheet From a new procedure Data is of the same form as ecological capture- recapture studies User – Trap session Cause – Animal

7. 7 Frank Matejcik SD School of Mines & Technology New Procedure 0) 1st group decides categories & their position 1) Individuals make Cause and Effect Diagrams 2) Make a group composite C & E diagram (no new contributions) 3) Complete a check sheet 4) Make additions to diagram and check sheet (if needed) 5) Analyze Check Sheet (Possibly with Capture-Recapture Methods) 6) Sample additional individuals (if needed)

8. 8 Frank Matejcik SD School of Mines & Technology State of the art of capture- recapture methods Mature area of Statistics, long history Accessible recent book is Amstrup 2005 Other uses including software testing Dedicated Software: MARK, CARE, Rcapture Research is ongoing –Session at JSM 2007 –JCGS March 2007 WINBUGS (Royle, et al)

9. 9 Frank Matejcik SD School of Mines & Technology Differences in our question & Solution approaches We seek to measure completeness, not size of population We consider planning for additional samples, sequential methods, limited users Continuous time not in Ishikawa procedure Tree structure is not in Ecological Studies

10. 10 Frank Matejcik SD School of Mines & Technology Follow up Pareto and qualitative, quantitative research The follow up “votes” can be questions weighting the causes, which be reported in Pareto diagrams Extended Ishikawa – Pareto Inspired (EIPI) Largely Basic Tools Integrated Qual-Quan Completeness Ordered elements

11. 11 Frank Matejcik SD School of Mines & Technology Current & future efforts Freshman Engineering students did C&E and check sheets Tried C&E and check sheets with 9 th grade Grad Student, Andreas Eikeland, prepared a set of fictional examples of use of EIPI Discussion of joint research with other SDSM&T faculty Formalize the methods, etc.
