Be wary of any distance between the engineers on the sales call and those who eventually appear in the repository. Insist on named engineers in the statement of work, with a provision that requires notice before anyone is swapped. A team that talks only about roles and refuses to name specific engineers is reserving the option to staff you with whoever is free.

Insist on access to the repository from day one. A partner that hands over a build only at the end of each phase expects you to accept a black box.
