The Roos won just seven games to finish 13th this year, giving opportunities to seven debutants while a number of their key players were sidelined with injury.
Scott, who was appointed Dean Laidley's successor mid-August, has been impressed by his players' enthusiasm to bounce back from the club's on-field woes of 2009.
"There are quite a few things we need to address and no-one by any measure can be satisfied with what occurred in 2009," he told afl.com.au.
"While I'm excited by the list, I think there are a lot of players who know this is a crucial season for them."
The club's move into its new Arden Street facility will coincide with the start of pre-season training and Scott said it was crucial his players returned from their break with an attitude to complement their resources.
He added that it was time to start from a higher base than the 'against-the-odds' mentality the Roos were known for.
"All the players when they come here, they've got to think, 'I have absolutely the best opportunity to get the most out of myself'," he said. "If we achieve that, then we're off to a good start.
"They have to come prepared to embrace that elite lifestyle that's going to get the best out of them. We will set no ceiling on the possibilities of what this football club can do in 2010. There'll be very high expectations and the players will be expected to live up to them.
"Success has many different definitions but there'll be absolutely no mention of 2010 being a development year for North. There's no reason why an 18, 19, 20-year-old can't exceed expectations. We've seen it time and time again with young players.
"They can achieve extraordinary things. We're certainly not going to put any limits on that."
However, Scott said the club would continue to be mindful of the pressure on one of its most high-profile players – midfielder Daniel Wells – as he sought to rebound from a season eventually ruined by osteitis pubis.
Wells played just seven games in 2009 after a pre-season that suggested he should produce the best football of his seven-year career.
"Daniel clearly has talent to burn but I'll be looking for him to really try to achieve his potential," Scott said.
"But what we have to do with Daniel is take the pressure off him. I've told him that he has to take the pressure off himself. The footy public put pressure on him but that is nowhere near the sort of pressure he puts on himself.
"He'll get my full support and we'll create a great environment for him. He's a player I'm absolutely sure that his best footy is certainly in front of him."
