Green Energy Solutions decided to start selling maintenance services to their install base of solar panels, in addition to the solar panel itself. GES would like better visibility into the value their maintenance contracts provide to customers by tracking the availability and reliability of their solar panels.

Which calculation is correct?

Show Suggested Answer Hide Answer
Suggested Answer: C

Salesforce Field Service uses two distinct KPIs for service contracts: Availability and Reliability. The two differ in whether planned downtime (scheduled maintenance) is counted against the asset.

Option C is correct. Availability measures the proportion of expected uptime that the Asset was usable, excluding only unplanned downtime. Planned maintenance is expected and excluded from the calculation, so Availability = (expected uptime - unplanned downtime) / expected uptime.

Option D is partially right in form but mislabeled --- Reliability is the metric that subtracts both planned and unplanned downtime: Reliability = (expected uptime - planned - unplanned downtime) / expected uptime. Mislabeling it as the Availability formula (Option A) is incorrect.

Option A is incorrect because that is the Reliability formula, not Availability.

Option B is incorrect because Asset Uptime is the numerator of these formulas, not a ratio of Availability divided by Reliability.

I think option C is the best choice. It focuses on unplanned downtime.

I thought reliability was just about uptime, not downtime.

I feel like I might be mixing up the definitions; isn't reliability more about the performance over time rather than just uptime?

I practiced a similar question where we had to differentiate between availability and reliability, but I can't recall the exact formulas.

I think option C sounds familiar because it focuses only on unplanned downtime, which makes sense for availability.

I remember we discussed availability calculations in class, but I'm not sure if planned downtime should be included.
