Create a word doc describing why you would choose this kind of UML class diagram over others

Using the given UML create a word doc. Some comments that you can add to the word doc are that when our team designed the project we wanted to ensure a user can load a profile be able to join the network leave the network whenever they felt like be able to update status be able to check what their current status is be able to add friends remove friends or search for a profile. The team created case statements where each task can be performed accordingly.
I wanted the network to give users the ability to choose what task they want to do so the team created a user prompt. Once a profile is created then you can search for it and make update if need to. I wanted some friends already in the network so that there was someone already to add when creating the profile. Similar to facebook having Zuckerberg as the first friend.
