Of their ships/commands. On ships/commands they were intimately knowledgeable of. Picard, prior to Encounter at Farpoint hadn't commanded a ship for 9 years. So it is reasonable to say he had a part in the construction etc of the ship. Sisko actually helped design the Defiant. But in a crisis, they didn't do the work, somebody else did. Janeway wasn't that far removed from being a peon when she took command of Voyager and because there were no starbases, probably had to take a more active role. Kirk was not intimately knowledgeable about the Enterprise B. Even watch TOS more, when he actually had to operate a control, it looked like he was hesitant.
