I need to create a solution / product based on PowerPoint and Excel.
This tool must be user friendly and portable to be able to fill it up by a client or account executive.
The data entered (either on a PPT or Excel or other) must reflect different behaviors in data visualization charts such as Matrix charts, pies, relationships etc.
I'm open to other workflows. I want to use Microsoft tools because the ease of use but maybe an online solution or stand alone software can be developped as version 2.0.
