Dedicated, noninterrupted, project work time is essential to any software development effort. Dedicated project time is necessary to enable progress on a project, because it’s nearly impossible to write code — much less to concentrate on larger, more impactful projects — when you’re thrashing between several tasks in the course of an hour. Therefore, the ability to work on a software project without interrupts is often an attractive reason for engineers to begin working on a development project. Such time must be aggressively defended.
