OCS Group UK is a £650 million facilities management company that has experienced growth from using Confluence, starting with 11 spaces and 182 users and growing to 3008 pages. They faced initial challenges with no IT support, bottlenecks, and system speed. However, they overcame these challenges by designating an IT champion, implementing a release cycle, and using cache macros and a local reporter. Looking ahead, they plan to reduce emails and improve accuracy with sales reporting, conduct a global rollout of Confluence to additional countries, and expand their training area.
