They were already far behind schedule before covid became an issue. The “other things” include a top-heavy bureaucratic management system that has an industry reputation of being glacially slow to respond to the need for change, and numerous waves of layoffs since the start of BfA that left them working on skeleton staffing even before the crit hit the fan.
I think that even at this point managers who are still part of the frat boy club are trying to gain territory in the hierarchy, while what few new hires they have been able to get are only on the learning curve.
