Regardless of how much time and effort are spent on preparing a course, it not until you deploy the course and work through the content, delivery, and technology that issues arise. There is always room for improvement, even in the most thoughtfully developed courses. Feedback provided by students can provide a framework of revision necessary for course improvement. All course components should be examined to make the course a better one the next time it is offered.
This is one of the most important comments of the class. I work for a college that we have limtited access to the Master Shell. So when there is a "problem" that needs fixed or something that needs tweaked we have to keep a list and then have access the next semester. By then, I forget.
