The dismal battlefield Book

A very effective book based on the seminal research in the types of power. It features a series of checklist and templates to create a system of analyzing your power inventory and needs. It is dated in the sense that it is written from an employee/employer standpoint rather than an entrepreneurial point of view. In addition, Cuming doesn't include any citations regarding the checklists and templates, so it's difficult to tell if they were tested or in what context they were tested.
