The team carefully reverse-engineered all the changes that had been made to the different environments and put them all into version control. They also automated their environment creation process so they could repeatedly and correctly spin up environments. Campbell-Pretty described the results, noting that “the time it took to get a correct environment went from eight weeks to one day. This was one of the key adjustments that allowed us to hit our objectives concerning our lead time, the cost to deliver, and the number of escaped defects that made it into production.”
