If you need to repair something on your car, you can probably find a step by step “how to” video online. Do you have access to repair type videos at work for your critical equipment? If not, ask vendors if they have some they could share with you and your team. If they don’t, offer to let them record at your facility using real equipment. If they aren’t interested, find a subject matter expert who might be.
You don’t need great production quality (though it helps); if you accurately document how to fix a specific issue, each video will be useful. Be sure it covers the “little tricks” involved in the repair such as the exact steps required to remove a particular assembly.
If you have dedicated “crack teams” for particular equipment, set aside training time to have them watch the videos pertaining to that equipment. Follow by having them explain how to do the repair discussed in a particular video.
If you keep a library of these in MP3 format, repair techs who lack training on certain equipment can get guidance to perform the repair more efficiently.
