Process Mapping software
The one we would recommend is from a company called Bizagi.
This is an excellent, easy to use, piece of software that is very intuitive and best of all it’s free.
The Bizagi site is full of tutorials and helpful videos etc
With very little practice your will be able to input and edit diagrams, add notes and output into a number of different formats. With a little more skill you can even auto generate reports and other goodies.
The software can be found at www.bizagi.com . The freeware can be found under the products tab and then the download tab.
