1) Developers build software. The success of people who /use/ software—including developers who use services via APIs—depends on testing, documentation, tech support… But if no one is focused on those things, they become part-time jobs, side hustles, and *they won’t get done*.

"I perceive three barriers to the adoption of trunk-based-development… * The need for Code Review. * A cultural assumption that you only commit (to master/trunk) when work is complete. * A lack of confidence in automated tests." davefarley.net/?p=269

How is it that a company like Accenture, that's held in contempt by actual experts for peddling stuff that does active destruction, nonetheless gets so much work? It's truly mysterious to me.

Automation pro tip: before you troubleshoot why Selenium isn't doing some complicated action, make sure the thing works at all. Ask me how I know.

I wish that people who can't do something wouldn't tell people who are doing it that it's impossible.

It’s not a great idea to use a machine to simulate “all the things a user would do” and leave things at that. Your current imagination is limited; the machinery’s is non-existent. It does not use or experience the product. YOU can do that, though. And your users definitely will.

Much testing focuses on confirming the product’s intended abilities. A more powerful goal for testing is discovering the product’s *unintended* *vulnerabilities*. The former can mostly be done by shallow testing: “Let’s try it. Yay! It works!” The latter may require deep testing.

In organization, trust is expressed in autonomy. Where autonomy is low, you can bet it is because trust is low. Where autonomy is high, you can bet it is because trust is high.

Agile is not about going faster. Agile is about destroying hope. The data produced by a good agile team provides a cold dose of reality to the managers — in time for them to — manage.

Sometimes you need to be disruptive before you can be constructive.

“You can’t say anything that might upset anyone else, and especially not people in management” is the opposite of psychological safety. It’s not about walking on eggs. Nor is the first half of this tweet justification for about being a jackass to others.
Vernon F. Sullivan retweeted
Being quiet about risks and hazards to avoid having uncomfortable conversations is the very opposite of psychological safety. Being afraid to speak out is hazardous. Feeling safe from discomfort is very different from being safe. Being afraid to make waves is un-safety.

If you're afraid of being fired then you're unlikely to be effective at leading change.

“I could fix it but it’s not my code” -> shared irresponsibility “Tom should fix that” -> shared dependency on responsible person “This is where we live, we build it up & keep it clean.” -> shared responsibility Too many times what should be SR is really SI. Why is that?
