Alex Papworth is running an online training session for business analysts and the discussion has turned to the challenges of workshops. Many feel the workshop format is inherently difficult (which I agree with.) I wanted to make a point and so put this together to help clarify my ideas.
Workshop complexity is the same as the Fred Brooks's Mythical Man Month, although I think a requirements workshop is even more complex as you have to address multiple issues in one session. This leads me to add another element to Fred's model;
(n(n − 1) / 2) Rn
Where Rn is the number of requirements being handled in the session.
Take a look.
