The task arose to assess the ease of use of the program, and not just "difficult-simple", but more objectively … Maybe there are some assessment systems that give a specific number that evaluates the simplicity, say on a 10-point scale or something like that. I would be grateful for your help. (sorry for the off-top, I didn't know which tags to specify :))
To objectively assess the ease of use of the program , put the user who sees it for the first time at it. Give the user a task (or several), which he must complete independently using this program. Measure the lead time. This will be an objective assessment of the ease of use of the program .
