Positive leaders are able to dramatically expand their people’s - and their own - capacity for excellence. And they accomplish this without enormous expenditures or huge heroic gestures. Here leading scholars - including Adam Grant, author of the bestselling Give and Take; positive organizational scholarship movement cofounders Kim Cameron and Robert Quinn; and thirteen more - describe how this is being done at companies such as Wells Fargo, Ford, Kelly Services, Burt’s Bees, Connecticut’s Griffin Hospital, the Michigan - based Zingerman’s Community of Businesses, and many others. They show that, like the butterfly in Brazil whose flapping wings create a typhoon in Texas, you can create profound positive change in your organization through simple actions and attitude shifts.
