SDLC Automation
SDLC Automation is a greenfield project that builds on the success we’ve had in automating the SDLC and takes it further. This blue‑sky project looks at ways we can greatly improve the SDLC process at Citi, taking ideas like grading engineering teams and rewarding those who follow best practices, perhaps moving them from manual approval to an automatic one. The use of Artificial Intelligence is highly likely.
