For me personally, written agreements are better because it is set in stone and nothing can be forgotten. If a verbal agreement is made, some of the things maybe forgotten by one or all members of the agreement. Projects can be started from verbal agreements but when having a written agreement, the project can be more successful since everything is written down. Verbal agreements can be changed for one’s personal benefit because it is very informal and this may hurt the other parties and possibly the company. If a verbal agreement is made for anything, it is better to follow up with a written consent immediately.
