There's an old saying that a pig doesn't get any fatter by being weighed and there's a lot of pig-weighing going in the software industry.
To me personally scrum rituals like daily standups are a minor nuisance. They are unproductive and often boring but most of the time you can get them over with relatively quickly.
What I really, really, really hate is the time registration tyranny where you have to do estimates, have meetings about estimates, remember to turn on and off timers, fiddle with timesheets when you forget about the timers, answer questions like "how will this change that everyone agrees needs to be done affect the estimates?" and defend why a task that was estimated to six hours took eight to complete.
I have ADHD, I have trouble making a realistic estimate on how long it takes to cook pasta and you expect me to be able to accurately predict how long it takes to compete a 3000+ hour project with a ton of external dependencies, arcane legacy code and agile constantly evolving requirements?
I understand that you need something to put on a bill that the customer will pay without complaining but come on, how can this be effective? Sometimes I feel I spend more time wrangling timesheets than actually coding.
