Systems analysis is "the process of studying a procedure or business to identify its goal and purposes and create systems and procedures that will efficiently achieve them". Another view sees systems analysis as a problem-solving technique that breaks a system down into its component pieces and analyses how well those parts work and interact to ...
Systems can be isolated, closed, or open. A system is a group of interacting or interrelated elements that act according to a set of rules to form a unified whole. [1] A system, surrounded and influenced by its environment, is described by its boundaries, structure and purpose and is expressed in its functioning.

Analysis (pl.: analyses) is the process of breaking a complex topic or substance into smaller parts in order to gain a better understanding of it. The technique has been applied in the study of mathematics and logic since before Aristotle (384–322 BC), though analysis as a formal concept is a relatively recent development.

Thus in product development, systems design involves the process of defining and developing systems, such as interfaces and data, for an electronic control system to satisfy specified requirements. Systems design could be seen as the application of systems theory to product development .
The term system is polysemic: Robert Hooke (1674) used it in multiple senses, in his System of the World, [7]: p.24 but also in the sense of the Ptolemaic system versus the Copernican system [8]: 450 of the relation of the planets to the fixed stars [9] which are cataloged in Hipparchus' and Ptolemy's Star catalog.

The purpose of a system is what it does (POSIWID) is a systems thinking heuristic coined by Stafford Beer, [1] who observed that there is "no point in claiming that the purpose of a system is to do what it constantly fails to do."
