This document describes the implementation of a Kanban system at a large energy company to achieve enterprise agility. It discusses how the company lacked process transparency, had a waterfall development approach, and IT was seen as unresponsive by the business. Kanban practices like visualization, limiting work-in-progress, and collaborative improvement were used. This reduced the backlog from 800 to 350 items within 4 months while new requests remained the same, improving productivity. The key lessons learned were to take an incremental approach to change, focus on shifting mindsets, and collaborate at all levels to sustain transformations.
