I want to add a technical factor - the thing that slows me down the most is lack of knowledge about peripheral operational details - what all the configuration files do, how my repository is templating something from a different repository, how all the deployment steps get executed etc. It’s a lot of details, many systems, some of which you only touch rarely so it’s very easy to lose track of things.
