I suppose I'm tainted because I've seen one too many methodology consultants. "What you're doing now is bad...but this new way will solve all your problems.." Enter "Value Scrum" your new savior.
After almost 3 decades in software, I've come to perceive a few things about the industry and the people in it, especially the new entrants:
1) All problems begin with "how can we solve this with new software/feature/etc?" because after all, we're software people and we make software so clearly software is the answer.
2) Society believes #1. They expect that all problems are solved with software. Not only does society believe this, VCs believe this also. There is incentive to behave as #1 in the hopes that it leads to $$$.
3) Anyone not believing #1 is a detractor, or worse, a Luddite. Technology as solution is the prevailing axiom. It is Maslow's hammer. All non-believers must be purged or cancelled.
So when I read what I'll admit is an enticing article that demonstrates experience and analytical thinking by the author I'm intrigued and mostly supportive. Just like software frameworks (yes, you Javascript community) the answer to problems is always a new present solution which one day will be a future problem whether it be tech or tech inspired methodology. Tech first problem solving usually always leads here.
I was also struck by an adaption of a statement I read once about XML. The adaptation follows: "Agile is like violence, if it isn't working you're not using enough of it."
So what does this mean, abandon all tech? No. It means, apply critical thinking. Let dissent be ok. Do the things the article suggests. You don't need training, or a seminar or a consultant. And if the leadership wants to do something you can't fully engage in, find something else to do. Don't waste your life.
