It’s a moot point now, but optimism and enthusiasm do not equal organization. What you are describing would have been a Grade-A cluster-f*** of epic proportions. I’ve run a lot of large projects where hundreds and sometimes thousands of people were involved. The last thing you want as a project manager is a whole bunch of highly motivated, enthusiastic people with absolutely no guidance or direction.
The last thing any inept project manager wants is to have the weakness and flaws of his plan pointed out and challenged.
