British Olympic chiefs want sports which underperformed in Beijing to pull their weight and help Team GB achieve their goals at the 2012 London Games.
Expectations have soared after Britain came fourth in the Beijing medal table.
"A number of sports that didn't do so well will have learned lessons," British Olympic Association chairman Lord Moynihan told BBC Radio 5 Live.
"And with consistent financing over the next four years, we'll see them lift to medal success as well [in 2012]."
Great Britain's 47-medal haul in Beijing - their best Olympic performance for 100 years - saw a significant number delivered via cycling, sailing, rowing and, to a lesser extent, swimming and boxing.
Yet despite the euphoria which accompanied Team GB's return on Monday, some sports such as athletics fell short of their pre-Games targets.
"We need to look at those sports that didn't deliver in the way we expected them to"Only 400m star Christine Ohurougu delivered a gold as the athletics squad ended up with four medals, short of the expected five, while Britain also failed to pick up a single medal in the relay events.
"It has been frustrating - we almost hit the target, but you don't get medals for coming close," said UK Athletics performance director Dave Collins.
Simon Clegg, Team GB's chef de mission, said officials would now take time to reflect upon the strengths and weaknesses of Britain's performances in Beijing.
"We need to sit down and analyse properly the results," he said.
"We need to look beneath the medal table at the number of finalists we've got.
BOA chef de mission Simon "We also need to look at those sports that didn't deliver in the way we expected them to."
Meanwhile, Olympics minister Tessa Jowell said UK Sport would be taking a "brutal" approach to allocating funding for 2012.
She told the BBC: "You know we've had the fantastic success in rowing, sailing and and swimming and cycling, and what will happen now is that UK Sport, which is the body which is charged by Government to oversee the development of elite sport, which has done a fantastic job in helping to get the organisation right, will look at the performance against investment across all the Olympic sports."
She added: "... It sounds brutal but it is, you invest where you're going to get the world class performance."
Other areas British Olympic chiefs may identify as underperforming include archery, tennis, equestrian and martial arts.
606: DEBATE
"We need a promise that the money will come," he said.
"Once we've got that, it gives us a platform, it doesn't provide the medals.
"We've then got to have the athletes and the support structure to move forward, but we need to have a strong funding base."
Having achieved fourth place in the medal table, which the BOA had set its sights on for 2012, questions are now being asked about fresh targets.
Though he refused to make any specific predictions, Lord Moynihan insisted that being on home soil could prove to be a further boost.
"When you're host nation, as we saw with the Chinese in Beijing, there is an inspirational factor that comes into play," he said.
"If you can inject that into the preparation and the results which we saw here, I think it will be a platform to build from."
