Guidance on Planning for Onboarding and Ongoing Operations
----------------------------------------------------------

This is a high-level view:

* Number of Parallel operations, for example BL and QAS, for best performance:

  * BL: 4x500 (4 Bulk Load sheets in parallel with a maximum of 500 rows per sheet). 
  * QAS: 5x200 (5 QAS Bulk Load sheets in parallel with a maximum of 200 rows per sheet).

* Recommendations for sync operations:

  * We recommend that you schedule sync operations during off-peak hours.
  * During business hours, sync operations are slower due to the presence of other
    work on the system.

* Scheduler Template settings (20%, 50%, 80%):

  * For periods of high self-service and administrative work (including API clients),
    we recommend that the template is set to 20%.
  * For periods of moderate self-service and administrative work (including API clients),
    we recommend that the template is set to 50%. This is the value in the system
    prior to SU-1.
  * For periods of low self-service and administrative work (including API clients),
    set the template to 80%. 
  * The current implementation only allows you to set 2 of the 3 values, that is
    a peak and an off-peak setting.

* In some cases, there are situations where VOSS Automate is used for changes. Ad Hoc syncs
  are best in this case.
* AS may choose to change CUCM and sync back to VOSS Automate. This is where you must
  schedule daily off-peak sync operations.
