  1. Sampling Procedures for Extending the Use of the Fishbone Diagram JOINT STATISTICAL MEETINGSSalt Lake CityJuly, 29 2007Frank Matejcik

  2. 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. Ishikawa DiagramCause & Effect, Fishbone

  4. 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 6s, other quality efforts since 1960’s • MS Visio, Dia (GNU), Open Office Draw

  5. 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. Use of Check Sheet • From a new procedure • Data is of the same form as ecological capture-recapture studies • User – Trap sessionCause – Animal

  7. 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. 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. 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-QuanCompletenessOrdered elements
