An Abstracted and Effective Capabilities Portfolio Management Methodology Using Enterprise or System of Systems Level Architecture

The purpose of this chapter is to provide an abstracted methodology for executing Capabilities Portfolio Management (hereafter, CPM) effectively based on the Department of Defense Architecture Framework version 2.0 (hereafter, DoDAF V2.0)1. A methodology is the specification of the process to follow together with the work products to be used and generated, plus the consideration of the people and tools involved, during a development effort. Based on the definition of methodology of ISO 24744 (ISO, 2007), this chapter provides process, product and modeling related technology as considerations of people and tools involved in CPM. From DoDAF V2.0, the purpose of developing an architecture is for beneficial use of it. A good set of architectural artifacts facilitates the manipulation and use of them in meeting its purposes of use. Systems engineering methodologies evolve to accommodate or to deal with problems in enterprise level, system of systems (hereafter, SoS) level and family of systems (hereafter, FoS) level. And the CPM of the United States Department of Defense (hereafter DoD) is a good example which demonstrates enterprise or SoS level problems. However, the complexity of the metamodel of DoDAF makes it difficult to develop and use the architecture models and their associated artifacts. DoDAF states that it was established to guide the development of architectures and to satisfy the demands for a structured and, repeatable method in evaluating alternatives which add value to decisions and management practices. One of the objectives of DoDAF V2.0 is to define concepts and models usable in DoD’s six core processes. DoDAF V2.0 provides a particular methodology in the architecture development process. However, DoDAF as well as other guidelines states requirements for CPM which is one of DoD’s six core processes, rather than how to perform CPM. This chapter provides an abstracted methodology for CPM which includes the process, abstrated products and tailored meta-models based on DoDAF Meta Model (hereafter, DM2).
