The author of The Great Game of Business, Jack Stack, wrote a nice recommendation for the new edition of Rock & Sand: A Practical Insight to Business Growth.

Here’s what he had to say about the Premium Edition of Rock & Sand:

Rock &Sand is a powerful and practical mini-book for entrepreneurs. If you want to unleash growth in your organization, this book shares a simple, practical process and set of tools to get it done. Michael Synk brings his coaching and teaching skills, along with a community of highly capable and experienced coaches from Gravitas Impact, to provide a growth roadmap that can apply not only to businesses but also non-profit organizations. The Rock & Sand framework matches up nicely as a complement to The Great Game of Business© framework and toolsets, as evidenced by the inclusion of our “Critical Number” principles in our Open Book Management philosophy that is the foundation of The Great Game of Business©.

Besides writing his own book, Stack is also the founder and serves as Chairman of the Board of SRC Holdings.

Thanks Jack.
