ABSTRACT
Operational requirements for systems engineering define the basic needs for answers to the questions. Functional requirements include necessary tasks that must be accomplished, actions that needs to be taken, and activities that needs to be performed. Functional review is a process of making decision on what has to be done to fulfill the requirements identified through requirements analysis of a system. Requirements analysis is conducted iteratively with functional analysis to optimize system’s performance requirements for identified functions and to verify that synthesized solutions can satisfy program and project requirements. The functional review focuses on what the system engineering must do to perform the required operational activities. It includes required inputs, outputs, and transformation rules. Integrated team development is making a team expertise in operationally employing a product or a software that is being developed. Subsystem level includes traceability to the system specification and down to applicable line replaceable units including software Operational Flight Programs or its equivalents.
