The cost of interrupted work (2023)

Some days an interruption will throw me off my train of thought, and I spend the remaining six hours collecting discarded bottles and railway ties for hopeful use somewhere, somehow, sometime.

Other days an interruption costs me pretty much nothing.

I’m still trying to figure out how to tell which of those days I’m going to have and whether to just not log into Slack for the day.

For me, it is more about the nature of the interruption. An easy question that only requires pulling something from memory doesn't cost much. A question that requires some thinking has a huge cost, even more so when you have to check the code or documentation. Sometimes even reading an email/teams notification can throw me off. It's not about the interaction (someone coming to your desk, a call,...), it's about the topic.

However I think that in both cases, if the interruption happens while coding, the risk of bug is about the same.
