A computer system that fails is a nuisance in some settings. In others, it’s catastrophic.
Take healthcare equipment, for example. Hospitals must have specialized systems that can be counted on to work in high-demand situations, an article on ExtremeTech explains.
Sophisticated equipment that won’t fail or get infected by malware requires a good preventative maintenance plan. Since there is constant change in technology, service providers need to keep revisiting those plans.
In fact, as a general rule, technical service providers should review their PM schedules more often than they probably do. They must make sure their software can store data from the various tasks technicians enter into the database.
Next, this database should be analyzed for trends that may indicate possible changes the service provider should make. Again, with technology and system upgrades changing so rapidly, it’s important that service providers keep in contact with equipment manufacturers more often. If not, service providers won’t be successful in fine-tuning their PM schedules to keep their customers up and running.
For hospitals and other medical facilities, there can’t be any down time. As the ExtremeTech article notes, their equipment needs to be immune to power fluctuations.
Furthermore, computer systems in hospital settings may be vulnerable to malware, since strict regulations don’t allow for security patches. That leaves those computers even more vulnerable to attacks.
