Replying to "Postmortems Help Address Causes of Errors" [Dface]

I’m going to write about the following paragraph:

The first sentence:

Oh ok, the way errors are connected to problems is that they’re evidence about the problem. Is that different than ‘evidence of the problem’? What’s the difference between ‘of’ and ‘about’? I’m thinking ‘of the problem’ means that you have a problem already set up. You got a specific problem in mind. If you get evidence about the problem then your mind isn’t made up yet about what the problem is. The problem can be bigger than you thought. The error could be evidence of that.

Ok, I see that the problems are described as “in our heads.” That’s a prepositional phrase describing where the problems are at. That’s significant cuz you could deal with a problem with somebody else, but your problem and their problem can be different in your heads. I don’t think they’d be so far off if it was an easy problem but it can happen. You guys could be in disagreement about what something means or how the problem is set up.

When I think about “problems in our heads.” I think about ongoing problems. Stuff that we’ve dealt with for a while already. We just haven’t been aware of them yet. Maybe we picked up a hint here or there but haven’t identified them yet.

Errors are mistakes you make. Often they come to mind cuz they result in failure at the goal. We may not know why they happen but we know there’s something to fix there. Maybe you run into too many errors and so have to probably be less ambitious with your goals. You can choose a goal that doesn’t fail cuz of an error.

Why are errors evidence about a problem? Idk but they convey information to us i think. When error x happens goal y fails. When error x does happen something else happens that looks part of the problem… Idk how to phrase that, but maybe you can learn more about the problem from that.

A problem is something that can be fixed or made better. How does that relate to an error? How does something being problematic relate to all this? Can solutions have errors in them? Or only plans or actions?
