Six days, four of them on site on your own repository. The two follow-up days come after, to correct, to extend and to check that the method holds without us.
4 days on site
At your offices, on your own repository, with a verifiable deliverable at the end of each day.
2 follow-up days
Two full days, not one-hour slots: the team comes back with whatever has been getting stuck since, and we work through it.
Closed within two months
The follow-up ends within two months of the last on-site day.
