The second important class of documentation concerns how to use technology. For example, a company that purchases machinery of any type, from punch presses to computers, needs manuals to explain to the people who will be using it how the equipment operates, when it is to be serviced, what to do when it fails, and so on. Likewise, if a company purchases software for its operations, it must also acquire manuals which explain how the software operates and provide instructions to employees on how to use it. Manufacturing concerns need extensive documentation to stay abreast of government regulations, safety standards, and other issues legislated by local federal, and state agencies.
