Rick Davies developed the basic idea (and its basic functioning) for this software application in 2015 while doing some prediction modelling for TripleLine, using the Rapid Miner suite of data mining tools (in particular the Decision Tree module). More information on his consulting background is available here
Since early 2016 Rick has been working with Aptivate (especially Mark Skipper), a Cambridge (UK) based software development company, to make a package of data analysis tools available in Excel. Excel was chosen as the platform because it is probably the most widely used data analysis tool, amongst Monitoring Evaluation staff and consultants
