Ulster supremo Dan McFarland believes that stability behind the scenes is crucial in these days of Covid disruption.
Coincidentally, that stability is a luxury that Ulster's next opponents Munster will find themselves without in the summer when they lose head coach Johann van Graan and senior coach Stephen Larkham.
Already, the Reds' performances have dipped since news of van Graan's departure was announced.
McFarland wasn't confident enough about the situation in his own squad to give a rundown of who is available for the Thomond Park clash as another round of PCR testing took place in Belfast yesterday.
But he is more optimistic that this interpro will go ahead than he was about festive meetings with Connacht and Leinster that fell foul of Covid.
"The Omicron variant is obviously way more transmissible, we've seen that through the squads," said McFarland.
"So you've got to be more aware, to be tighter on the things that you do and try to avoid it as much as you can.
"You're always trying to adapt but we've been doing for quite a long time anyway, so there were days when you could only do certain things.
"Or take the week of Connacht, we left the ground on the day that a couple of positives came. You're trying to make sure that you're creating as little risk as possible."
While Munster returned to action last Saturday in their disappointing loss to Connacht, Ulster have kicked their heels since the December 17 victory over Northampton Saints in the Champions Cup.
As he pointed out, Ulster haven't won in Limerick since 2014 and Munster will be fired up to respond after the weekend.
But McFarland is confident that his team can pick up from where they left off because of the structures that are in place.
"Rugby is an extremely complex game, it has 15 people on the park with a lot of different elements and people doing widely different things and as a consequence, with all that complexity and moving parts, cohesion becomes a premium," he said.
"You can simplify as much as you can but, at the level we're playing at, complete simplicity is not going to win you anything, is it?
"The opposition teams are good enough to spot that. You have to have a certain amount of complexity in there.
"It's that balance - complex enough that it's able to break down the opposition, but clear enough that you're able to execute.
"That's the skill in the coaching - in producing systems that you can use week in, week out.
"That's the point when it comes to the breaks, to playing for a few games and then stopping.
"It's, are you able to go back to the systems you've been using so guys can click back into it.
"The big parts of that system, I'm very used to.
"If you were in a situation where things were evolving and changing week to week, that would make it very difficult.
"I reckon if this happened in a club putting in place lots of new systems that would be extremely difficult.
"I'd say if it was all staccato and a new coach, that becomes very difficult."
