Yesterday I finally turned over what my latest web based class. A module was left off due to a dead laptop, a funeral, and massive illness eating 2 weeks of dev time. If my job had faster iterations per class it wouldn't be so annoying to leave off a module. I'd simply tell myself that I'd get back to it in the next iteration. Unfortunately, there are often months or years between course updates due to the time involved in producing an update as well as shifting corporate priorities. I would my current workplace stuck in an ADDIE process, but that's not quite true.
