We accomplish this transformation through supporting daily operations with a hyper focus on triage and then root cause by understanding the business impact of our products. The goal of every biz ops team is to shift left to be more proactive and upfront in the development process, and to proactively manage production and change activities to maximize customer experience, and increase the overall value of supported applications. Biz Ops teams also focus on risk management by tying all our activities together with an overarching responsibility for compliance and risk mitigation across all our environments.
