i would like to know if there are a way to measure the team members of scrum team individually, all the measure i found apply over the team, and have really sense because the idea is share all the work and responsability about the increment of the product. But in my organisation want to have and a way to prove with numbres if a person is good in his job beyond all the good comments of others team members or quality of the product develop by the team. What PKI can use?
