Today, there seems to be a generational divide over the issue of whether to use written procedures (older workers) or videos (younger workers). Each method has its strengths and weaknesses. For example, you can visually scan a procedure to quickly get to a key point, but you can’t do that with a video. With a video, however, you can show each step of a PM task being performed rather than try to paint a picture with words.
In some cases, a written procedure is required by an outside party (e.g., a government agency or an insurer or for satisfying the conditions of a manufacturer’s warranty). In those cases, nothing says you can’t also use a video.
Since both methods are available, you are probably better off having a mix rather than going strictly with one or the other. A good approach is to write lean procedures and include in them references to “See it Done” videos. Update both as needed.
