Get a Grip is a companion book to Traction. Our recommendation is to purchase Get a Grip in audio format so you can listen to the dynamics between members of the executive team of a technology services firm going through the growing pains of implementing EOS.
After you have listened to Get a Grip, read through Traction and use physical copy of Traction as a reference guide. You will also want to check out the freely available resources from eosworldwide.
