This is essentially an Engineering assessment of device capabilities and understanding of the device.
Product management reviews the Enhancement Requests and move them to a customer based request backlog. Once the Enhancement Request (device certification release) has been allocated a release, the product manager will contact you regarding their inquiry and will let you know when to anticipate needing more information to scope the request, as well as confirm access to the device.
The scoping of the device will occur as soon as the device is available. Scoping usually takes few hours upto a day. Once the scoping is completed, the supportability of the device certification will be known - if the requested is not available or cannot be delivered, you will be notified and the Enhancement Request will be rejected. Once it has been determined that the device functionality can be supported, the scoped Enhancement Request will be placed in the DSr commitment backlog. Product management will commit to get them a release target for their request.
