I've always done this. My coworkers have been frustrated with me in the past for asking them to write things down, because some of them overestimate my ability to listen to them speak for 5-10 minutes and remember every detail. It's very hard to forget what is written down.
Recently, I neglected to write down my thinking and progress for a week, and I was at a loss for where to begin the following Monday. Keeping a work journal (in my case, a linear text document with an entry for each day) is the most important productivity habit I have.
Somewhat OT, but tangentially related: One of my clients likes to tell me his work requirements by telling me long-winded stories about how he came up with an idea, what exactly happened, etc. that was useful at first but became extremely wasteful of time as years passed. I tried typing down notes while he talked, but it became too hard to write useful ones.
At some point, I resorted to keeping an audio recording of the whole meeting just to make sure I have something to come back to, in case my notes fail me.
I wouldn't do this for everything, but it helped me realize that an audio/video log like a dashcam video can work for certain scenarios.
I write it as a prose. Mostly because that's the form I enjoy the most to write, and also because it's mostly about writing it more than reading it later on
