Retrospective

Could have been better….Need design boards and multiple screens

Takes too much time if everyone isn’t on the same page

Interruptions (timer)

Mob too big, try with a smaller group

Too many people

Lost track of objective

RolesIt’s hard driving with my mouth shut

Hard not to just type ideas

Need to know when to shut up

Being a navigator was initially confusing

It took a while to get what everyone was trying to say

What went wellFriendly atmosphere and very collaborative

Good mix of abilities

Good to learn other approaches

Discussions were interesting

Good that non coders took part

Nice approach to enter into one’s head

No merge conflicts as done as a team
