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.
Visio 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.
VISIO also presents a fairly large range of figures, themes and is equipped with industry standardization systems, Business Process Model and Notation (BPMN) 2.0 and (IEEE), allowing each design is based on reality; , Including compliance with the Unified Modeling Language (UML) 2.4
In my work we handle quite complex telecommunications systems, so the use of plans is necessary, VISIO is very useful since it allows us to create the flow diagrams, travel plans of the services and electronic architecture plans of the equipment, all this in a very friendly and understandable way with a high level of detail.
