The Great Game of Business is the title of a book and an open-book management system (that is the focus of the book). The Great Game of Business on Getting Employees to Hold Each Other Accountable discusses 4 steps to implementing The Great Game:

1. Focus on the Critical Number – Find a Common Goal
   
2. Act on the Right Drivers – Create Line-of-Sight
   
3. Follow the Action & Keep Score – Hold Each Other Accountable
   
4. Provide a Stake in the Outcome – Reward & Recognize
   

It focuses on Follow the Action & Keep Score – Hold Each Other Accountable and includes an audio clip from the President of The Great Game of Business:

In terms of employee engagement, this means creating an environment where managers don't hold employees accountable but, rather, where employees hold themselves accountable, based on the common pursuit of a "critical number," which can vary depending on the business.

Many successful ESOP companies utilize an open-book management (OBM) system. The post notes that fourteen of the 15 2008 Top Small Workplaces have successfully implemented OBM, "helping them maintain steady revenue growth to the tune of 23%, on average, over the last two years."
