Lean theory as to why Mob Programming works. Waste is directly proportional to the number of handoffs, handbacks and delays in workflow. Mob-programming eliminates all of these. The waste from these can represent 70-90% of the work being done.
@WoodyZuill wanted to make sure you saw this.
to be clear. Mob Programming didn't come from Lean (I've had lots of conversations with @WoodyZuill) but it helps explain who understanding theory can help you learn new practices. 1/
@WoodyZuill When I first heard of MP I didn't see how it could work. But the more I investigated the more I saw it was consistent with Lean/Flow/ToC theory - hence it meant my not seeing how it could work said more about me than about it. 2/
@WoodyZuill Kind of like how for years scientists' theories said bumblebees couldn't fly. Clearly something wasn't understood since, in fact, bublebees do fly. Saying things don't work when they do (or do work when they don't) says more about you than what you are discussing. 3/3
what would it be like if, instead of being told what practices you needed to do, you were presented both with a way of choosing your own way of working along with a theory as to why those choices were good.
We no longer need to stay in framework prison. This is what DA is about.
beauty of knowing why something works and where it works lets you know when you should not use it. Or, if you want to try, let's you know why any problems may be going against theory.

an example of why we need more than empiricism. Imagine the theory underneath this about sub-atomic particles that you cannot observe. This theory is useful, but not observable - only (in)validatable with experiments.
Consider how this odd behavior can now be understood, how its implications (death by radiation poisoning) can be understood and dealt with (lead as a protective shield).
Now, consider a Scrum team process. If you get wierd behavior what do you do? Without theory you just have to stick to Scrum practices or insert other practices. But, since Scrum creates a psychological barrier to stay within its sopce, you may never find a way out. 3/

Trump's covid plan is apparently to let people get sick, and use his miracle cure. Of course, part of his plan is to eliminate insurance for people with pre-existing conditions. And he ignores the 10s of thousands of dollars in healthcare people are gong to have to pay.
this is a big issue. He's hoping all this fuss will have people ignore he owes almost half a billion dollars to people (likely the russians). And that he's trying to take away women's rights. Not to mention he's creating a white terrorist group to do his biding.
his gaslighting on ballots (no swing state sends ballots without request) takes our eyes of the GOP voter suppression. The environment, bounties, disrespect for our vets and many other things are being ignored due to cognitive overload.

@JoshBurdick72 @PavelASamsonov which is part of why visibility is so important. and maybe, dare I say it, it might be useful to have a manager at a daily standup hearing "I'm blocked because I don't get enough time with a PO" Oh, but we can't do that - it'd be horrible.
@JoshBurdick72 @PavelASamsonov what would have more impact to a manager?
1-hearing 3rd hand-via SM-that a team's having troubles or
2-seeing 1st hand a team is having troubles

this whole keep the manager out of the daily standup is an acccommodation to the fact that Scrum takes a negative attitude to managers
@JoshBurdick72 @PavelASamsonov i'm not saying managers should be there either. I'm saying you have to do what works. and you can't prescribe that.

Random thoughts about Scrum Guide Based Scrum.
i was surprised to see an audio by Ken Schwaber on the Dangers of customizing Scrum.
Instead of espousing against modification you'd think there'd be a discussion on how to lower the risks.
will be writing a page on random thoughts regarding the difference between SG Scrum (Scrum guide based Scrum) and DA Scrum (Lean/Flow/ToC based Scrum).

The biggest one is Scrum being based on values and practices with no theory and DA being based on theory that enables choice.

if you're smarter than someone who has had decades more training and experience than you then what are you not smartest in? Challenging experts is always good if you're trying to learn something. But recognize who is probably right while you're learning.
This goes for everywhere
the exception to this is when there's a mindshift involved. So when 5% disagree w/95%, one should look to see if the 5% are coming from a different place. If so, worth examing that diff. For example, Agile started out with a minority, but was based on different undrestanding
however, when two disparate groups are interpreting the same data with the same science and one side has 95% agreement, they are virtually always correct. When the 5% has been correct they've been able to make more accurate predictions as to what's going to happen.

I am really amazed how so many people just want to be right about masks. It's not a big deal to wear them. I don't care if it's right or not. It seems a more rational decision when risks are concerned. Not to mention those who've studied these diseases think it's best. ...
if you think you're smarter than someone who's studied something for decades then what are you not the smartest person about? This is a statement that you know more than anyone else about everything. It's incredibly arrogant and like a bull in a china shop. ...
there's no rationality here. It means you think what you think is the truth. Oh yeah, you can find evidence that meets your beliefs, but cognitive bias has it meet that. That's still you saying you can interpret data better than an expert. ...
