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

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

5
Use of Check Sheet
• From a new procedure
• Data is of the same form
as ecological capturerecapture studies
• User – Trap session
Cause – Animal

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)

•
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)

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
