This software developed by Microsoft is excellent, it is more than a simple design tool, it is like magic, with it you can capture a whole process and do it in a very professional way, since it has pre-designed figures and a great variety of topics. Microsoft Visio Premium 2010 Retail Box is so powerful that with this software you can create flow diagrams, construction plans, floor plans, data flow diagrams, flow charts, process flow diagrams, business process modeling, 3D maps, lane diagrams and much more. So basically it allows to simplify and communicate complex information with linked data diagrams created with a few steps and in a short time. i Mainly DISLIKE THE FACT that the software is not included in the microsoft office package, so it's a bit tedious to get it
