The system lifecycle is a view of a system or proposed system that addresses all phases of its existence to include system conception, design and development, production and/or construction, distribution, operation, maintenance and support, retirement, phase-out, and disposal.
Software reviews and audit. v. t. e. A concept of operations (abbreviated CONOPS, CONOPs, [1] or ConOps[2]) is a document describing the characteristics of a proposed system from the viewpoint of an individual who will use that system. Examples include business requirements specification or stakeholder requirements specification (StRS).
A system architecture primarily concentrates on the internal interfaces among the system's components or subsystems, and on the interface (s) between the system and its external environment, especially the user. (In the specific case of computer systems, this latter, special, interface is known as the computer human interface, AKA human ...
Systems theory is the transdisciplinary [1] study of systems, i.e. cohesive groups of interrelated, interdependent components that can be natural or artificial. Every system has causal boundaries, is influenced by its context, defined by its structure, function and role, and expressed through its relations with other systems.
In 2022, researchers proposed a staging system for CAD. This system is based on the amount of plaque measured in the coronary arteries using a type of imaging called coronary computed tomography ...
System of systems. System of systems is a collection of task-oriented or dedicated systems that pool their resources and capabilities together to create a new, more complex system which offers more functionality and performance than simply the sum of the constituent systems. Currently, systems of systems is a critical research discipline for ...
System analysis researchers apply methodology to the systems involved, forming an overall picture. System analysis is used in every field where something is developed. Analysis can also be a series of components that perform organic functions together, such as systems engineering. Systems engineering is an interdisciplinary field of engineering ...
Business requirements. Business requirements, also known as stakeholder requirements specifications (StRS), describe the characteristics of a proposed system from the viewpoint of the system's end user like a CONOPS. Products, systems, software, and processes are ways of how to deliver, satisfy, or meet business requirements.
