Old habits die hard. I've always been interested in system analysis and in particular, business process mapping. This isn't the same as mind mapping.
I was looking for a reference to IDEF design methodology. The topic had come up in a meeting last week. In the process I found a good site that had some basic descriptions of LEAN and Six Sigma. The description of IDEF wasn't that great but the LEAN discussion was.
I did find some IDEF descriptions in a paper. Figure 3 is a nice view of the basic IDEF0 diagram.
