The Best Business Tools - A Facilitator's Toolbox

My Facilitation Toolbox on Index Cards

I'm a former engineer.
I carried a well-stocked toolbox when I was an engineer... and I like to have the same as a facilitator.

This is a stack of index cards that has all of my favorite models, frameworks, and notes.
When I plan a session, I sort through the cards to build an agenda with my client. There are about 50 cards in my collection.

Below is a list of my most-used tools. Tools at the top of the list are used daily.
In the middle are tools I use weekly. At the bottom are tools I use monthly (or so).
