Anybody who was a change agent or acted as one knows this too well. You meet a development team of 15+ engineers and do an introductory talk on Scrum. Even before you are one third through the talk, there is a question or an interruption from the audience - similar to one of the following examples:
- this is all very interesting, but how it [Scrum] would deal with a situation when half of the team quits their job on one day?
- this may work in an experienced team, but imagine that you have a team where there is just one experienced developer and all others are fresh graduates
- I don't understand why you are against my idea of recording the stand-up meetings; sometimes the amount of input from the team may be too large for the Scrum Master to remember
