A more thorough explanation:

Composite work is a term used to describe a type of work that involves multiple tasks or activities. It refers to the combination of different types of work that are performed together to achieve a common goal.

For example, a construction project involves composite work because it requires different types of work such as excavation, foundation work, framing, electrical work, plumbing, and finishing work. All of these tasks are performed together to complete the project.

Another example of composite work is a movie production. It involves different types of work such as writing, directing, acting, cinematography, editing, and sound design. All of these tasks are performed together to create a movie.
