Shawna,

My issue here is not the honesty of the team but the lack of having accurate timelines. If you stated in 2018 that this would take 5 years to develop and delivered on that plan, I don't think the community would have much frustration. The issue at hand is that your team is somehow promising releases before all of the testing is completed. This puts us in a bad situation with our stakeholders when we are relaying promises that are never kept.

I don't know how you can now expect anyone to trust timelines of new feature releases. Going forward I will have to wait until the actual release date to start planning for new features rather than have time to prepare my team for them. Please ask the developers to only relay a new go-live expectation once testing is fully completed. Delivering is much more important than trying to appease the community with an earlier release date.
