Man, transmission shortages, missing bumpers, busted rear ends. Why is this such a surprise to Ford? They've been planning this release for like 2 years. Is it that hard to plan for and actually execute timely production of a vehicle these days?
Short answer: yes. A HUGE
YES. Given how many parts these days are farmed out to contractors (and very possibly subcontractors) and/or different company-owned manufacturing facilities, coordinating everything for a synchronized "time on target" is an absolute logistical nightmare. Everything from raw materials shortages, to equipment failure, to weather, to traffic conditions between Plant A and Plant B can cause a domino effect that results in production delays. Keep in mind that final assembly plants generally don't have more than a few days' worth of parts on-hand at any given time (usually less, actually)... and if they churn through that supply before whatever upstream issue exists gets resolved, then there's nothing to do but delay final assembly.
It's not like going to Ikea and dragging home a Raptor kit where everything is in the box and you just need to put it all together... you've got engines coming in from one place, transmissions from another, suspension bits from some place else, axles from another still... and so on and so forth. If you come up short on any one of those things, it's not like they build partial trucks that are complete except for the missing piece; they have to delay the whole thing.
Honestly, it's miraculous that anything gets built at all, IMO.
