Right. What would typically happen in our D&D 4e games is that there would be an obstacle/complication or objection/question to resolve under the umbrella of the overarching challenge. Initiative was set and everyone joined in because otherwise they didn't earn XP. When someone resolved the immediate issue, another would be presented. If it happened that the complication that was presented was one for which the character up in initiative was not well-suited, that player might try to employ a secondary skill, if it made sense to do so and provided enough of a benefit, or attempt to Aid Another. Aid Another had a bit of a risk to it since you could botch the roll and contribute a -1 penalty instead of a +2 bonus to the primary skill check. But if initiative fell in an optimal order, you could stack up to 4 bonuses (+8 altogether) to the next primary skill check which left some wiggle room for offsetting bad Aid Another rolls.The thing is, I don’t think there would be much need to mandate each character to roll, if the skill challenge was tied to an evolving narrative. You describe the scene including an obstacle or source of conflict, and ask the first player in the order (be it initiative, or just going around the table or whatever) what they do. You resolve that action, narrate it’s consequences, leading a new decision point, so you ask the next player in the order what they do. This is just a slightly more formalized version of the fundamental pattern of play. Sure, if a player says they don’t want to do anything, you can let them, but if the scenario has meaningful stakes and dynamic conflict, it’s as unlikely a player won’t want to try anything as it is a player will want to use their turn in combat doing nothing.
Oft forgotten by DMs though was Advantages which were absolutely necessary when running Complexity 3, 4 or 5 skill challenges. I don't remember the statistics exactly anymore, but the math guy in my group showed the calculations that the chance of failing the skill challenge went up greatly to a near possibility without Advantages (at least on offer). To my knowledge, those were only included in the RC and not in previous iterations of skill challenges. Anyway, this was another way for a player to try to offset any particular deficiency with the character's ability to overcome the complications presented to them.
