Project Quiver Phase 3 Planning

Engineering
1

In order to achieve the milestones in the Phase 3 proposal , Alperen and I have prepared a Gantt chart to help keep us on track. We applied some conservative estimates on the time require to complete these task and are open to feedback and discussion. We plan to discuss this timeline during the calls this week. Please review and let us know if you believe some items are missing or require more time/attention. At the start of each week, we’ll meet to set that week’s milestones and goals. Our aim is to drive consistent team documentation in preparation for a detailed Flight & Owner’s Manual for the dev kit.

We have a lot to get done the following months but I believe we can achieve all of these milestones and launch a successful dev kit!
