There is no product I have ever more hated than my @HP printer. Unable to print from Windows 11 even after installing their software. "Printer requires attention" even though it prints just fine from a Windows 10 machine on the same network. YOU PEOPLE HAD ONE JOB AND YOU FAILED!

Horizontal slicing is how most software teams work. The most difficult/challenging software skill is vertical slicing. Those who master it attain software superpowers.

@ejames_c If a lot of your basic equipment is broken and nobody bothers, being good at data is maybe not your highest priority? Most orgs seem to struggle with the 101 levels, mostly due to short-term "numbers" pressure.

@ejames_c I think in either industry the gap between the best and the rest is enormous. Very few manufacturing firms do Lean/SPC well, very few software orgs do Lean/Agile well. Mostly a leadership/culture problem, only then a knowledge problem.

I'm actually starting to suspect that the best manufacturers have more to teach software folk than vice versa. This is not a strong opinion, and I want to retain the ability to revise it. But manufacturing is harder, older, and lower margin.
David Chapman@Meaningness

Reading Goldratt's The Goal, you think "omg, manufacturing management is actually not using the simple optimization algorithms we learn in second year CS classes??" And this, similarly, makes me want to buy a defunct American chemical factory and get it running properly!

@ejames_c Just curious, are you familiar with Cynefin? Nigel Thurlow's (et al) FLOW system? Dan Vacanti's work on Kanban flow metrics?

@ejames_c One of the biggest shortcomings of the Agile Manifesto is the implicit assumption that all items in the backlog have value and thus all of the resulting software does. But that's because they wanted to address broken software development first. To get to some level of control.

“But software is not like manufacturing! It doesn’t have repeatable processes!” Spoiler alert: SPC is about tracking changes in variation, not about repeatability. This unlocks a lot of things. x.com/ejames_c/statu…

@matsonj @angrynoah @Meaningness Colin always chuckled at me when I said “but software is not repeatable!” Every complex system shows variation. Measuring + tracking changes in variation will let you uncover the causal mechanism of the system. Now imagine: you track variation of value flows in your software.

@ejames_c Software development is/happens in a complex adaptive system, so they went with principles and heuristics rather than a prescriptive playbook.

@TheCynefinCo @snowded Would a cross-functional team be considered a “silo” in the context of this post? The specialization and shared mental model would be focused on problem / value domain rather than sameness of skill set?

Knowledge wasn’t a company asset until it was written down so that it was possessed independently of the employee, and there was concern that the company's knowledge walked out of the door every night. @snowded 🤜 "The Importance of silos" hubs.la/Q02lVNRs0

@swardley Probably safe to assume that many of the more diverse, less popular folks don’t pay Elon any money so their posts get less visibility from the algorithms?

One of the most valuable things about X/Twitter is that I would hear diverse and often unheard voices. Is it me, or has anyone noticed that the algorithms behind X/Twitter seem to favour the same popular, tired voices now? It's becoming a celebrity foghorn, not a community.

@ejames_c All that said, my background is in TQM/SPC, so maybe I am just mentally (too much?) contrasting software dev with the idea of large, repeatable runs of same things. Your application to the processes behind selling items or gaining subscribers seem close enough to that, so yeah 👍

For those who have been looking into Understanding Variation and had your mind blown and your view of data completely transformed, you will naturally ask why process behaviour charts aren’t more popular outside of lean or manufacturing circles. Good question! A short thread.
Benedict Fritz@benedictfritz

@ejames_c Got Wheeler’s Understanding Variation and it’s also blowing my mind a bit…why aren’t control charts more common in charting tools? Is there some big drawback? Googled around and seems most content seems lean six sigma oriented but that’s mostly it?

@ejames_c @danielwithmusic Well, technically it's what's in the Manifesto and I don't claim more wisdom than that. But saying that Agile doesn't work because someone has been subjected to shallow Scrum (my sympathies!) is kinda like saying tennis sucks after playing doubles at the local senior center.

@mathiase @danielwithmusic As for ‘what is true Agile’, I’ll defer to you on that — I don’t actually know what Agile (or true Agile) actually is.

@ejames_c @danielwithmusic Afaik the statistics don't work as well without a "stable process". If there's low volume of data points and a lot of VUCA, you can have relatively high special vs common cause variation and thus the outliers would seem to be less clear?

@ejames_c @danielwithmusic In high complexity situations, special cause variation dominates because a) few data points (low volume) and b) novelty -> limited repeatability. Good Agile implements short feedback loops that allow for rapid adjustment. Process control tends to work better for ordered systems.

@ejames_c @danielwithmusic Sorry, but no. This thread confuses Agile with (bad) Scrum. The Agile Manifesto mentions none of these "low-value processes" - there is no "Agile process". Agile at its core is about narrowing the uncertainty funnel and adapting to emergent reality.
