I remember when we were expecting our first child, we went through a 'parenting school' - a course where all kinds of doctors, psychologists, nurses, nutritionists, etc. came to teach us, future parents, about parenthood. Since it's not maths, a lot of them had different views on different things, which confused people. Until one day, one future mother, all anxious (if you're a parent, you'll understand the psychological state of expecting a first baby in the next month or two) asked almost angrily: "You people give us conflicting advises, what should we do? How do we do good when even you don't agree what's good between each other???" The answer was simple: "We give you all views, all options. It's up to you which one you think is right and good for your kid. That's what parenting is. That's why we are all different people."

Same thing works for companies. Leadership shapes the company. There is no one-size-fit-all strategy. What works for one company, doesn't work for another. Two pizza team size can work somewhere. Somewhere else something else will. People tend to look for manuals, instructions on how to do things, expecting that someone will write it all down and they just need to do what's written. From time to time, we get to hypes about something (check under microservices for example), everyone use it because it's popular, fancy, buzz word. Without thinking - do we really need this? It's like an epidemic (or pandemic?) of paper pushers, no one wants to take responsibility. To take action. And there is no responsibility if you do things as it's written in the manual, right?

Best methodology is - work with your team. Talk to the team. Know how they breathe. And they will tell you what to do, how to organise them, which methodology to use.
