Unlike in the case of central IT systems such as servers, client users work directly on their end devices. As a result, they might damage their clients intentionally or unintentionally. For example, they could kick IT systems standing on the floor, trip over cables and damage interfaces, or spill liquids onto devices. If no quick replacement is available, the user in question will not be able to work with the IT system affected until repairs are completed. If a mobile device such as a laptop fails while the user is on the move, they are often only able to continue working after returning to their organisation.
