The document discusses three different views of the world according to businesses, workers, and customers. The business view focuses on processes, the worker view focuses on adaptive case management and dealing with exceptions, and the customer view focuses on having their problems solved through any channel. There is a collision between these different worlds, so a new toolset is needed to reconcile the views and focus on customers, understanding their problems and journey, and creating value at every step from their perspective. The new toolset includes adaptive case management, service design, and focusing on information flows rather than document stocks.
