====== Easter Test for Good Operators ======

The quality of a facility manager and the installed control and monitoring system can be easily verified using the **Easter Test**, which consists of evaluating the answer to one simple question:

<jumbotron>Can you show us the trend of measured data from last year's Easter Monday?</jumbotron>

Easter Monday has several ideal characteristics for this test:
  * It is a movable feast, so it typically cannot be easily pre-programmed into the control system as a recurring holiday.
  * We ask for "last year" to determine if data is being archived for a sufficiently long period.
  * For most technical equipment, a public holiday should result in a visible change in the character of the data (e.g., lower occupancy, reduced heating/ventilation).

===== Typical Problematic Answers =====

  * **"I can't, we don't have data that old. We only keep trends for XY days."**
    * **Solution**: Use [[en:mervis-db:00-start|Mervis DB]] for long-term centralized storage.
  * **"Yes, but we would need to call in the I&C (BMS) programmer for such a task."**
    * **Solution**: Ensure your data is accessible via a user-friendly database like [[en:mervis-db:00-start|Mervis DB]].
  * **"Probably, but I don't know how."**
    * **Solution**: Train the operators in using the SCADA application or migrate to the more intuitive [[en:mervis-scada:00-start|Mervis SCADA]].
  * **"Yes, but the data looks exactly like any other Monday."**
    * **Solution**: This indicates that the operator does not use (or know how to use) the scheduling functions, or the installed system does not allow for exception-based holiday scheduling. Use the scheduling tools in [[en:mervis-scada:00-start|Mervis SCADA]].
