Microtasking, in order to work properly, requires a certain amount of discipline. First of all, all tasks and communications about them have to happen in tickets. However, our customers are far from being disciplined enough to use tickets for every requirement they have. Instead, they make phone calls, chat with us online, and send emails. I believe that is the responsibility of an architect to make sure each request that is coming from a client turns into a ticket. If you, as an architect, don't do that, you are doing a very bad favor to the project.
