This document discusses CA Technologies' journey to scale agile practices in its mainframe product development environment. It went through 4 phases: 1) Initially following agile rituals but facing challenges around roles, collaboration and individual performance goals. 2) Doing agile practices but still facing challenges around inclusiveness, planning and managing different work. 3) Being more agile through coaching, changes to appraisal and rewards, but still facing challenges around time to market and waste. 4) Continuously improving practices such as adopting incremental releases, improving automation and identifying waste. The overall journey aimed to transform the organization to better adopt agile principles and practices for mainframe product development.
