Hi AndersonMomoko,
Glad to hear you are impressed with what we are looking to build with Productivity Score. For your question around a release date, we don't have a date on when it will become generally available yet. We want to get feedback from people like you so we can make a solution that would fit your needs. Until we get that feedback and understand what you want added/changed it is hard to give an accurate date.
For processing requests, on the employee experience preview we will be processing requests around the 15th of every month. On the technology experience preview, the team is in the process of selecting organizations that they would like to work with. If you are selected to participate in the technology experience preview you will get a message from the team.
