A tale of cars (surprise!):
I have a DeLorean (for over 30 years, it was cheap, and I am not giving it away). I had some work to be done when it moved to Germany with me. I tried 2 major specialists:
One has a warehouse full of workers, quoted me a million things to "fix", including many I was aware of (that dent in the fender has been there since it joined my family and, yes, it used to have a car phone installed - I wish I still had that time piece!). They also threatened me after I posted a picture of my car in their workshop without their explicit permission.
The other one is a one-person show, super relaxed guy who makes much of his money on parts and has no interest in managing a large crew. He told me I am free to choose what I want him to do, the main thing I need is patience. Covid hit, the car spent 3 years at his shop, we did quite a few things when he had time and I had money (he did ultimately convince me to trash the original alternator, which is utter rubbish). He picked me up at the train station when I came to get the car, I took it on the freeway, drove 300km back to Germany, and passed the TUV en route. I then recalled the display cabinet he had with the gifts that customers had sent him, including a few from Japan.
When I see "thought leadership" (always with air quotes) on social media, you can immediately tell which type of person / business is behind it. You can't blame anyone for wanting to make a living and pay for kids' education (in countries where you have to pay). But the strong smell of "everyone else is wrong, I am enlightened and can show you the true path" always turns me off. I once told my client that if they told me after a workshop: "look, this is utter nonsense and entirely useless", I'd apologize for taking their time and wouldn't send a bill.
The major irony in this is that many of these folks advise their customers to take a long-term, strategic view on architecture decisions, when they themselves focus entirely on the transaction and not the long-term value of a customer relationship.
ps: the garage below is neither shop, as you can tell from that random Rolls Royce cluttering the photo :-)
