Decision Matrix plugin

Hi guys,

I’m looking for a convenient way to provide a decision matrix / PUGH Matrix on our homepage.

Basically its a spreadsheet with different options, criteria and values, how well the options fulfil the criteria. The sticking point: The User shoud be able to insert his very own, personal weights (see the following example). The spreadsheet should, based on the weights (given by the user) and the values (given by me), be able to calculate the ‘best option’.

Look for an example here – except that I want do fix the options, criteria and values. The User may only change the weights.
