System Definition (glossary)
A set of core technical activities of systems engineering, including the activities that are completed primarily in the front-end portion of the system design. This consists of the definition of system requirements, design of the physical and logical systems architecture, and system analysis. (Created for SEBoK)

This definition was developed for the SEBoK.
Discussion
"System definition" is also used in the SEBoK as a knowledge area (KA); it includes several front-end systems engineering (SE) activities such as system requirements development, systems architecture, and system analysis. (See System Definition KA.) This generally aligns with the "concept stage" as discussed in the International Council on Systems Engineering (INCOSE) Systems Engineering Handbook (INCOSE 2012). In the SEBoK, concept definition is used to discuss the assessment of the mission and stakeholder requirements.
