IMI- Hate it for several reasons.
-Easy to mandate by those at "echelons above reality" (as the Army guys would say, I think) but impose a growing burden on the operational world.
-Cutesy, fancy, flashy presentations waste our time without a lot of value added.
-Do not, do not, do not force me to listen to a narrator for information. I'll click through it, let it play on mute while I get actual work done, etc. Put information in text so that I can read/skim through it which goes a lot more quickly than listening to some narrator. Plus, it lets people who know the material or don't care skim through and glean key info while letting those who need more time with the material read more slowly and revisit the info. Audio does not force me to listen to what I would not read. It makes me turn the sound off. At least with text I'll take a quick glance.
-Flashy media is often bogged down by military internet connections.
-Simple media items that the tech geeks think everyone has on their computer may not be present on military computers. I'm the victim of a new set of IMI that we are required to complete, but none of the computers at my unit can run it due to a missing "codec." Since we can't load software on our own computers, I had to call the central help desk, where they spent an hour trying to remotely fix my computer to no avail. Now we are marching toward the deadline for course completion and no one has gotten their computer fixed so they can even start doing the course.
-All too often, the IMIs are making us do courses we would have blown off in the past, while they haven't caught up to the courses we have to take every year and would be more efficient online. Example, I'd much rather click through a IMI for my yearly NBC or marksmanship fundamentals classes that I've had 12 times now, but I still have to go sit out on bleachers and listen to an instructor who really wants to be a DI enjoy his opportunity to waste our time and treat us like recruits.
