Lots of good comments. I’ll just add that next time the business set a promised delivery date you do you own estimate and let them know the promised date is unrealistic ASAP. Don’t try adjust the estimate so it fits, give them the estimate for the features promised and have the conversation about what needs to be dropped to meet the delivery date. If it is possible to add devs instead do that as early as possible. That’s a very professional approach that no one can fault.
