Hi Mark, just a thought ...
I would think that a TDD course would be about programming. Certainly mine would, with developers working in pairs.
I¡¯d be reviewing the team¡¯s code after frequent iterations, answering questions, and so on. I don¡¯t see how I could possibly provide value to 60 people at once.
Generally Chet and I limit our CSD courses to 24.
As part of that improvement effort, we'd like to have a 2-3 day on-site Advanced Test Driven Development course in April 2015 for about 60 people.
