Systems Engineering Glossary
Two or more entities that interact with one another to produce an effect (emergent property) that is not inherent in the entities themselves.
|System Acceptance Review (SAR)|
The application of a systematic engineering methodology that examines the system as a whole and its impact on its environment.
Documentation that identifies all the necessary components of a system, their role, and their interaction in order for the system to meet its objectives.
|System Design Review (SDR)|
A methodology for understanding the behavior of a system over time.
|System Engineering Management Plan (SEMP)|
The effort to progressively combine all of the system components to ensure that they work together as intended.
|System Integration and Test (SIAT)|
|System Life Cycle||
The scope and period of a system’s evolution, beginning with the determination of an unsatisfied need through all subsequent phases and proceeding through system disposal.
|System Requirements Review (SRR)||
A review that examines and determines success in defining technical requirements based upon user requirements.
All of the information that defines the system baseline from requirements to acceptance criteria.
A system under consideration.
A group of autonomous systems whose interaction with one another provides more capabilities than the individual systems alone provide.
A technique to help understand complex system interactions. It enables analysis of system boundaries and provides insight into how a change in one factor might have an impact elsewhere in the system.
|Systems Engineering (SE)||
The interdisciplinary approach governing the total technical effort required to transform a need or opportunity into a system solution.
|Systems Engineering Plan (SEP)||
A document that describes the technical approach for how the processes and activities of the life cycle stages will be managed and conducted. Also known as a Systems Engineering Management Plan (SEMP).
