While I was participating in a conference call with my team mates, I released I need something to be done by the project manager. I wrote a short memo on a sticky note and handed it to him. He took the note and placed it on his laptop,
It becomes the most immediate and visible memo, surpassing any email request and any other notes he took on his Microsoft OneNote.
After the meeting ended and everybody got back to their desks, my request was completed ten minutes after wards.
Electronic notes are hidden inside files, folders and Apps, while papers are mostly visible and exist beyond the limitations of computer screens, this is why they are more power full.
