One of the hardest tasks strategists and enterprise architects face is mapping an enterprise in a form that creates and supports making sense of the whole. This book introduces an alternate approach to create consistency at every level by modelling the enterprise as services with the Enterprise Canvas. This new model type that can be used to describe just about anything in any area and at any level of the enterprise, and that acts as a consistent frame for all the other models that we need in our architectures. It is also simple enough to scribble on the back of a napkin - and engage all of your stakeholders in the enterprise-scale conversations you need. There is also a simple notation for Enterprise Canvas that is suitable for use in service-design toolsets.The book teaches the use of architectural techniques to describe any aspect of the enterprise.

The result of careful and meticulous research, this stylishly-written biography of infamous blues musician Robert Johnson reveals the real story behind the mythical talent that made him a musical legend. According to some, Robert Johnson learned guitar by trading his soul away to the Devil at a crossroads in rural Mississippi. When he died at age 27 of a mysterious poisoning, many superstitious fans came to believe that the Devil had returned to take his due. This diligent study of Johnson's life debunks these myths while emphasizing the effect that Robert Johnson, said to be the greatest blues musician who ever lived, has had on modern musicians such as Eric Clapton and the Rolling Stones and fans of the blues. Tom Graves, a master of what Ernest Hemingway called "the true sentence" and the telling detail, pieces together the fragments of the jagged, elusive puzzle that is Robert Johnson.
