I feel your pain, I went through it just last week. Part of the resolution was much stricter processes and procedures for stepping through the SDLC environments. The team I work on does not have a tiered development environment but one of the groups we work with does, so we have to approximate it as much as possible. Fortunately, the system is young enough that we can make changes for the better.
