Architectural decomposition: The role of granularity and decomposition viewpoint

Abstract

Before any platform development, one must create the representation of the products’ architectures. Typically, one would start by decomposing the existing or proposed systems into smaller subsystems or modules. This is a critical step since the remainder of the platform development will depend on the choices made at the decomposition phase. This chapter will discuss how to decompose a product architecture. Specifically we will address the decomposition choices such as level of granularity and different decomposition viewpoints and how they affect the final resulting architecture.
