Not only that, but by not having a consistent schedule, for example 40 hours a week, makes it impossible to know how long an upcoming feature is going to take. Because there are people who are willing to do those herculean tasks in the ridiculous timeframe and then burn out. So mangement never really learns anything and continues pushing features at the same pace. It is in your companies best interest to have a predicatable schedule.
