Use the following cycle to move devices from a Poor or Fair Health Score to a Good or Excellent one, and to measure the value of that improvement over time.
Baseline: a snapshot of the data at a point of time, in practice this could be the first of every month.
Investigate: analysis of the Health Score for devices grouped from Poor to Good, as shown in Health Status on the Dashboard tab of the Desktop Visualizer (see View the Desktop Dashboard). For more on Health Score bands, see Understanding the Health Score.
Remediate: improve and address issues found on the devices Poor to Good categories.
Measure improvement: at the end of the period, review the baseline against the current state.
Return on value (ROV): a calculated return of value metric helps to understand the impact of degraded user experience and to aid the decisions for mitigating activities.
Repeat this cycle on a regular basis. Initially, it is good to work on a monthly review cycle. As the issues become easier to mitigate, you can shift this approach to a quarterly process.
TIP: Keep a list of devices that have been reviewed and have had issues addressed. These can become samples to re-check over time.
