I have to admit I popped a monocle when I saw the estimate for what is described as a rudimentary ecommerce website without even basic features like authentication and payment come down to 43 team-weeks, or in other words 12,040 team-hours. Even at one person per team being billed as $20/hr this works out to almost a quarter million dollars.
I understand the numbers are given as an example but I think the problem is that the scale of the task hardly justifies the complexity of the planning and using "teams" and "weeks" as sizes instead of "developers" and "hours/days".
