effective EFL implementation

Hi there,
This very good friend of mine needs to prepare this presentation on "How would I make sure that the EFL (english as a foreign language) teaching methods she introduces would be met within the different/changing environments". She is to show how exactly would she make sure that the members of her team follow the methods she introduces. As it is to be of the work interview she's very nervous.
Apart from tortures and eavesdropping I can't think of any more :-D. Seriously though, would anybody here have some suggestions to put her in the right direction?

Would appreciate anything,

Rather than eavesdropping, you could try observing. Also, records of work done, getting feedback from both the students and teachers, testing which follows the class methods.

Thanks a lot, these are really helpful. Would you think of any other ways of checking how successful the implementation has been?
