A system is a complex set of parts that
come together to serve a common purpose. Essentially a system is a solution to a complex problem.
A system
combines a number of resources together in an organised manner
to perform a collection of specified functions to a specified
level of performance
In systems engineering, the parts of the system are end products and enabling products.
There are two ways
to describe a system: in functional terms, or in
physical terms. Both functional and physical descriptions are valid descriptions
in their own right and each can live independently of
the other. A systems engineering approach relies on understanding not
only the two descriptions, but also their inter-relationship, which leads
to a deeper appreciation of the system and forces
an understanding of traceability (a cornerstone of systems engineering).
