Thursday, June 15, 2023 - 10:00 am10:25 am

Shimpei Sasano, JCB Co., Ltd., and Ryotaro Takeda, NTT Data Corporation


In this talk, we will share our transition of the SRE team's engagement model from a start-up to a team capable of supporting a 400-person organization. We responded to challenges as the business and organization grew by changing the team's engagement model and mission through three main phases: Launch, Specialization, Expansion. We hope our transition story can provide some insights for those planning to build or expand an SRE team.
