Set counts of most relevant maintenance notifications and alerts
Focus your attention on machine areas that require maintenance and replace a cryptic error code with a clear problem description and measures/instructions to fix it
Analyze sensors and signals that have caused the issue, generate proactive rules and start discovering patterns to steadily built more and more advanced algorithms that will generate predictive models and automated notifications
Simplicity is not the goal. It is the by-product of a good idea and modest expectations.
