The first CMMS appeared around 1965 and was used by large manufacturers that owned IBM mainframe computers (the beastly kinds that are not used anymore). Technicians would log data on punchcards that were fed to the computer. Years later, they would log data on paper that was given to data entry specialists. Only in the 1980s when computers became more usable did technicians log data themselves directly into the system.
Usability is now less of an issue in the 21st century with personal computers. And a CMMS is not reserved for large manufacturers that have high maintenance budgets. Today, a CMMS is used by companies that have Internet in their facility and even the smallest maintenance budgets. This is because CMMS solutions are web-based and relatively affordable. For instance, UpKeep’s solutions start at $35/technician/month. There is even a free version.
Accessibility and affordability aside, today, a CMMS is judged mainly on its features and ease of use. Usability is still an important factor because, as more features are added, CMMS solutions can become increasingly complex which decreases any chance for successful implementation.
