Chris=2C

The focus of development team is controlled by setting a metric=A0threshold=
 or just excluding some. So you do not have an overhead for the development=
 team from the point it set forward=2C assuming them team committed to=A0ad=
herence=A0it.

Your strategy for perfection may vary.=A0You can start with 8 for CC in new=
 project=2C or with a higher level of 15 in an existing project. Where you =
end up / the team agrees upon=2C depends on team commitment to the goal you=
 set. There is no gold median=2C there is just recommendation=2C how you fl=
uctuate from it and what reason you face with depends on team.

Thanks.
