Even in the digital age it is sometimes necessary to carry background information around with you in a folder because, for example, you need to be able to see that manual or to be able to show that you are carrying the safety regulations during any checks.
This information is usually located in a thick folder in the back seat of your car or on the corner of your desk. Carrying this folder around can cause annoyance from time to time because it is not always necessary but you are required to carry it with you.
An additional work instruction is another example. You have an extensive work instruction for your employee, but if this has to be processed in the digital form, it becomes all very unclear to find the right information between everything else.
