First things first, it might be worth checking if there is a specific lesson plan format that you need to follow. Some schools, colleges and universities have a standardised format to follow as this makes it easier for another teacher to use if you are unexpectedly away from work. While there are many different formats you can use for a lesson plan, most contain the same core elements. The title and time of the lesson are basic pieces of information and a list of required materials ensures no essentials are missed out.
Lesson plans are great for other settings as well. For example, if you plan on retraining your staff to use a certain piece of software, a plan can help keep them on task and give them a goal to work for each day. This will allow you to incorporate these new lessons into their workday without a significant decrease in their normal jobs. Having a fixed set of tasks to learn also helps employees stay organized and on task.
