Software engineers are constantly delivering products to customers. I assume the timeline for an electrical engineering project can be many months or even years, so this isn't very surprising. When you work in an environment using continuous delivery and you are shipping features to customers every day/week, there's no way you can not have more communication. These things have to be documented, support staff trained, project goals tracked, etc.
