CRO utilizes data and intuition in a predictable, repeatable and measurable way to improve key performance metrics. Digital marketers can learn from agile methodology, lean methodology, and CMM which focus on iterative processes, early delivery, continuous improvement, and adapting to change. VWO's agile CRO principles emphasize working with real data not opinions, optimizing for speed, and ensuring people, processes and tools are given equal importance to successfully run optimization campaigns.
