As one who has participated in many Agile teams as both an individual contributor and as a lead/manager I would say Agile adds a lot of complexity and overhead due to the number of people involved--engineers, designers, product managers, etc. When companies have too much money, they feel they have to spend it, and so they spend it on hiring too many engineers, designers, product managers, etc. And they also feel they have to keep tweaking things when things are good enough to be left alone, in order to justify all the hiring. It's basically busy work on top of busy work. My most productive times as a programmer was when it was just me and another programmer hammering out 500+ lines of code per day and where we were our own product managers. When you have a team of 10-12, you need to spend a lot of time creating well-sized tickets (that really are ludicrously small) that are doable in the allocated time of the sprint. Then each programmer spends, say 2 weeks in a 2-week sprint, producing about 50 lines of code, testing it, and then deploying. TL;DR: There are too many hires (engineers, product managers, etc.) and not enough work, so we end up doing a lot of busy work. That is Agile. EDIT: to fix typo.
