The role of Business Operations Organization is to be the production readiness steward for Mastercard products. As a Business Operations we are responsible for ensuring that our platform is stable and healthy. We break down barriers to run our products by fostering developer run ownership and empowering developers to build resilient products. We support our developers during the application build phase in software run principals that includes operational design, automation, capacity planning, monitoring that leads to fault-tolerant, scalable products. We see the big picture and help create and enforce operations standards while facilitating an agile and learning culture.
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.
