Computer failure at some time is almost inevitable and can represent a major financial loss to the user. It therefore becomes important for any company that is dependent in some form, whether on a large or small computer system, to cover this eventuality by taking out an adequate maintenance contract.

The author illustrates the manner in which independent maintainers can be of assistance and how professionally based are their back‐up services.
