A printed document can be useful during one activity and become superfluous in another. The evaluation should know who consults it and for what task. Reducing the number of prints has operational significance when it retains access to the necessary information, without transferring obstacles to work.
I propose to observe some recurring documents and their path. A print can be accessed, annotated, or archived without use. Comparison with a digital mode must consider available devices and real conditions, avoiding assuming that everyone can read on the screen in the same way.
Let's imagine a list used during the preparation of orders. A digital version can only be useful if it remains accessible near the location and allows the necessary verifications. Sheet saving does not alone describe the quality of the solution.
The test should compare materials used and difficulties emerged. Adequate data and perimeter are needed to assess wider environmental effects. The choice becomes understandable when the format is linked to actual use and resource reduction is verified along with work continuity.
