Reduction Analysis (AKA Decomposing)
The purpose of this task is to gain a greater understanding of the logic of the product as well as its interactions with external elements. Whether an application, a system, or an entire environment, it needs to be divided into smaller containers or compartments. Those might be subroutines, modules, or objects if focusing on software; computers, operating systems, and protocols if focusing on systems or networks; or departments, tasks, and networks if focusing on an entire business infrastructure. Each identified subelement should be evaluated in order to understand inputs, processing, security, data management, storage, and outputs. This is also sometimes referred to as decomposing the application, system, or environment.
