ovvero : componente personalizzata ("break/fix") del servizio di assistenza tecnica

il break-and-fix (o *break'n'fix*) si riferisce a un servizio di assistenza svolto in-situ, a secondo dei bisogni puntuali del cliente : lo tradurrei quindi come *personalizzato (e mirato)* o *su misura*, lasciando comunque tra parentesi l'espressione inglese che presenta varie formulazioni : break/fix, break-fix, break-and-fix o addirittura break-n-fix

"Break'n'fix services is defined as the labor and parts portion of on-site or carry-in maintenance on PC equipment. PC equipment includes desktop PCs, portable PCs, PC servers, printers and LAN hardware.

Repairs and Maintenance

Most businesses, in their similar dependence on their electronic equipment, update their machines on a three-year cycle, often replacing dated systems with entirely new ones. Schools in general, and Tolland’s schools in particular, simply cannot fund newequipment at that rate. A four-year replacement schedule is recommended in the districtStrategic Technology Plan; but, in reality Tolland observes a five or six-year schedule. To save money, Technology Services frequently updates machine components instead of replacing systems and, in every case, machines move from role to role and room to room,as the hardware “aging process” dictates, until they are (thoroughly) obsolete.
Almost all repair and maintenance jobs are handled internally instead of by outsideservice providers. All members of the Technology Services staff share in repair,maintenance, and upgrade tasks with the majority of responsibility for desktop systemsfalling to the district’s Computer Technical Specialist and the majority of theresponsibility for network operations falling to the district’s Network Administrator."
