The ADM forms the core of TOGAF The result of contributions from many architecture practitioners It is specifically designed to address enterprise’s business and ITneeds by providing:–A set of architecture views (business, data, application, technology)–Guidelines on tools for architecture development–A set of recommended deliverables–Links to practical case studies–A method for managing requirementsSlide 4 of 19Copyright 2009-2011, The Open Group2

The following statements describe the phases of the ADM,except ?A. They are cyclical.B. They are iterative.C. Each phase refines the scope.D. Each phase is mandatory.E. The phases cycle through a range of architecture views.Slide 18 of 19Copyright 2009-2011, The Open Group9
