Software for project work flows and process maps: Visio or other tools?

[mountaingoat]

I'm designing an NGS project and would like to show the steps in a visual manner, including tasks, scientists' names, and software choices over the course of the project.

Would Visio be a good tool for this? Have you found certain Visio templates to be especially useful for NGS work flow and process mapping?

Free programs

If you would rather prefer free / open source programs, then give these a spin:

• dia -- for flow diagrams, etc
• inkscape -- more general drawing program
• scribus -- desktop-publishing program
