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


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


Technology

Use of Check Sheet

• From a new procedure

• Data is of the same form as ecological capture-recapture studies

• User – Trap sessionCause – Animal


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)


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)


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-QuanCompletenessOrdered elements
