We've got a new resource from Brent Snow at 10,000 Feet, creators of the popular simulation Interplay, the interactive game-based workshop that's been called a "mini MBA-in-a-Day."

Interplay builds a broad understanding of the critical factors that influence success or failure in any organization. Besides having a lot of fun, participants compete as executive leaders of a growing enterprise and finish the workshop with the kind of knowledge that's built from experience.

This handy reference of key financial ratios all business leaders must know is a great resource to have at your fingertips.
