I wonder, was the Enterprise really that unprepared for battle as it seemed to be because Jellico started barking orders.
One might imagine that a ship that has faced serious opponents in battle, like the Borg, would be ready to fight at anytime.
Would Picard really run his ship that makes possibly dangerous first contacts and explores new areas so poorly that when someone else takes command, everything needs to be changed?
If the Enterprise wouldn't be ready for serious situations, what might that say about Picard? And Riker and all the others.
All that shift rotation and making the ship ready for battle thing was nonsense.
You'd think then, that in all their complaining about having to make the changes, someone would actually say "This is unnecessary" "We're already oriented for this "War" you're talking about." "None of these changes will affect any noticeable difference" etc... but nobody says any of that.
Nobody refutes the man's assessment, that the ship requires reorienting from a science & exploration bearing, to a wartime bearing, that might be different in some way, not even the former captain, when the subject is brought up contentiously, in private.
Privately, Geordi even admits that he has no problem doing the work, just that the time constraints are taxing. I know that if someone is telling me to make changes that don't need to be changed, or might in fact be problematic, even if they are a superior officer, I'll most likely tell them, on the spot, & tell them every detail of why they're wasting everyone's time, albeit it... tactfully lol
When we look at Picard's wartime Enterprise in Yesterday's Enterprise, does it not look completely different to the one we routinely see? Different postings on the ship, different energy usage, & overall bearing? It may be an alternate timeline, but it's pretty much the same ship, with mostly the same history, leading up to where they had to go to war
Jellico has reassigned portions of nonessential science people, removed science stations from the bridge, shored up security, asked for engine specifications so he can likely tax them far longer than just an occasional surprise battle that Picard might find himself in with the ship. I have no problem imagining that the ship he is gearing up to have is very similar to the Yesterday's Enterprise one, just from the things he's asking for.
