RE: Drawing Charts
Hi Debbie
A swim lane is a type of process flow diagram that depicts what or who is working on a particular subset of a process.
Eg. you might split your diagram up into 4 columns (lanes), each titled with a different person (Tom, Harry, Susan, Greg), and then place boxes/shapes (tasks) underneath someone's name if it's their task to do, then join up with arrows to show the flow process.
Hope this answers your question.
