Sociotechnical Systems - Elements

In a computer system, software and hardware are interdependent - software without hardware is just an abstraction, and hardware without software is inert. When integrated, they form a machine capable of complex computations. This illustrates that a system is more than the sum of its parts, and software systems are part of broader sociotechnical systems involving people, processes, and organizations.

What are the two main categories of elements that make up a sociotechnical system?
