"Agile in Practice - Big Visible Charts"

Oldie but a goodie here: a nice 3.5' introduction to agile team use of big visible charts (aka "big visual chart", "BVC"). It addresses rationale as well as categories of BVC’s and general usage. Also included are useful criteria for evaluating any set of BVC's.

Of course, these days, any such set of BVC's is often called a "dashboard", or an” information radiator.”

Which reminds me. There is a powerful rationale for BVC’s (or whiteboards or canvases) in any sort of project work, not just agile. In my practice, I have often found that when issues and conflicts arise, it is much more productive to have the various parties’ eyes on a BVC than to have them looking into each others’ eyes. The latter tends to create adversaries. The former tends to lessen forgetting, to clarify doubts, to open new perspectives, and to lead to group annotations and sketching that actually help to resolve doubts and misunderstandings as well as to maintain good working relationships.
