A work order is any form of work that does not take place with a regularity for one and the same model. It can be e.g. repair or installation.
Work order is, in the system, a living document where several technicians can work simultaneously to facilitate traceability of what has been done and what needs to be done.
A signature is required to approve a work order. This signature can either be filled in by the responsible technician or the customer. If work on the work order is carried out on several different occasions, the work order is partially signed.
