Learn from the mistakes of others

While I've not looked at it yet myself (not even had brekkie!) these surveys are going to be problematic - though 365 is hardly representative, you'd be wanting 3-4 times that many - or at least 10% - would you not?

I'm getting very curious about the factors, the actual factors, that come into play when the size +/- complexity of a project grows - or where it hits some kind of 'critical mass' (wherever, whatever, that might be).
