When doing product comparisons of competitors products, I have to create a comparison between featuresets, something like this:
http://www.adobe.com/uk/products/acrobat/product-comparison.html
At first, I would really just like to be able to represent this graphically inside of Aha, using an excel spreadsheet as a source would be a suitable option.
In the long run, it would be great if features that are already completed inside of Aha could be used to generate this list on the "My product" side so that it could be dynamically updated....
Through Product Notes, you can create tables to create comparison tables for your competitors. You may have also seen our recent launch to the Strategy->Competitors section which highlights the ability to create competitive analyses (and to chart them against each other in a matrix)
