Hello I have to do a proposal including timings for a solution in which there will be 300 end users of a new system aimed at improving efficiency in the work place(!).
What percentage of these 300 do I need to observe in their place of work, interview and so on for the information to be representative of the whole? Many thanks! . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
