More than a decade ago, Mark Johnson, SAP's Henning Kagermann, and Clayton Christensen hashed out the principles of business model reinvention in the pages of the Harvard Business Review. Essentially, a business model can be broken down into four distinct elements:

1. A value proposition
2. 2. Resources 
3. 3. Processes,
4. 4. A profit formula

 This means in practice that the new and different must be separated and even protected from the tried and true. As Mark says, "To play a new game on a new field requires a new game plan." —Clayton M. Christensen

It is a pleasure to welcome the author of multiple titles, a great friend of the show, and the co-author of that 2008 paper Clay mentioned, a Top 50 HBR article of all time, Reinventing Your Business Model; Mark W. Johnson.
