Planning sessions, daily scrums, retrospectives, increment reviews.
Are these all, in the end, overhead to be eliminated along the way to some Agile Nirvana?
Maybe, but not for me and maybe not for you.
If learning from our past is valuable, there's value to looking back a bit and trying to scope out how to improve.
Days are those 24-hour bits with the dark/light thing happening. (In most places.)
Weeks are those 7-day things that most cultures use to decide when to go out for pizza or wash the deck.
All these intervals are part of the rhythm of our lives, for better or worse.
We could meet briefly daily to see how we're doing, whether anyone needs help, or to decide where lunch will be.
We could meet every week or two to take a step back and look at how we're doing overall, even if we've been deep into it all the time.
That might be worth considering.
But what if we're all in the room or the garage or wherever we do this stuff that we do? Then are these activities all overhead, to be eliminated?
And that might work just fine. It might be the ideal place to be.
YMMV, but I need and appreciate a little nudge to look at the larger scale.
