Jackpocket, an online lottery ticket purchasing platform, adopted the DevOps culture by implementing DORA metrics and using Sleuth as a tool to track these metrics. The company's engineering team increased releases on their largest repository by about 200%, going from one release per week to 3.2 per week. Jackpocket operationalizes engineering efficiency best practices using Sleuth and DORA metrics, which has helped them reduce batch size, improve deployment frequency, and minimize rollbacks and incidents.
