Hughes was unveiled as QPR's new boss on Wednesday, and outlined his intention to stay at the club for at least the duration of his two-and-a-half-year contract.
However, while Beard is confident that Hughes will be a success at Loftus Road, he also acknowledges that football is a results-based business where there are no guarantees.
"Every football club - and there are probably 12 or 13 of them - have got to contemplate what happens if they don't perform as well as they need to on the pitch," said Beard.
"The aim is that Mark is here for a very long time and sees through the objectives and the aims.
"As far as I'm concerned, Mark is here now to help us fulfil both on the pitch what we want to achieve and help me with his expertise and his team implementing a training ground we can be proud of for the club."
Hughes's first game in charge of the club will be against Newcastle on Sunday.
