This model is a copy based on a model created by Thorbjoen Mann Owner, Thorbjoern Mann Consulting
for an blog article:
A couple of liberties were taken with this version or interpretation. The original model did not have arrows, so it is my interpretation as to direction. Stocks were chosen because of presentation. It does not imply quantity. Certain elements in the original model were not enclosed in boxes. These were assigned to variable primitives to differentiate them from boxed elements. The Insightmaker Folder capability was used to group what appeared to be common elements together. The Folders can be opens by clicking the + sign in each folder.
