At level five you reach the level of  performing elementary actions. Often this level is referred to as the level of Working instructions. Here is a heavy emphasis on the HOW-question. In most organizations the business departments themselves are responsible for these working instructions and make them in tools like Word or Excel. You can think of input instructions with screen prints included, job manuals, or checklists that can be used to make sure all tasks are performed.

For BPM engagements you should avoid to describe this level of detail yourself. If they are available though, you can make use of them to get a clear insight of what people are actually doing and maybe recognize some more pain points.
