What would you say is the minimum / appropriate team size and project duration for using Scrum?
We're thinking about using Scrum for our next software project (about 1600 - 1800 Man-hours) with a team size of 7 members. Since the team size is pretty big (in relation to the project duration, but cant avoid that), would you prefer Scrum?
7 members in a team is perfect from SCRUM. The only reasons why you would consider some other process instead of SCRUM:
Finally, in SCRUM you first experiment little bit in order to find the perfect balance. (That comes from SCRUM being empirical process)
