I developed a limited implementation of VDML (Value Delivery Modeling Language) using spreadsheets to illustrate the concepts and develop a better understanding of the value computations. The document describing this implementation and a companion Excel workbook are available at the VDMBee web site: http://vdmbee.com/2015/01/exploring-vdml-spreadsheets/
I would be interested in feedback, particularly on VDML since the spreadsheet implementation is essentially a prototype, but the technique can be used for a limited application of VDML.
For more on VDML, see my overview at http://fredacummins.blogspot.com/2013/02/value-delivery-modeling-language-vdml_4878.html
