This approach is not one I want to take up. I think dismissing arguments with general appeals to diversity vs. subjectivity is a bit of a copout and has been heavily overused. I admitted that some good may come out of some of the methodologies; some people simply need more structure than others, more guidance. But many work best independently and can manage large and complicated projects.
What I absolutely will not back down on is the vitality of concentration. All the methodologies make for extra meetings, which are usually complete wastes of time and constitute interruptions, which are bad for work quality and productivity.
I will answer in more detail to your other response. Thanks for reading.
