booking.com is running 1,000 experiments at any one time and 30,000 annually. How do traditional Business to Consumer (B2C) organisations keep pace? One Feature at a Time (1FaaT™) offers a nine step guide to established B2C organisations in pursuit of digital native competitors. Born digital companies deliver more value faster by engaging customers in a process of ongoing digital experimentation. Older companies can do this every bit as well, but first they must overcome the cultural debt that impedes their realisation of opportunities. This can be achieved through implementing 1FaaT™. Creating digital value at pace without sacrificing governance, regulatory compliance or security is proven to be achievable by older B2C organisations. 1FaaT™ borrows wisdom from these changed organisations and helps leaders to reimagine their people and team interactions. Using Agile and Lean theory interspersed with real world anecdotes 1FaaT™ is an essential handbook for leaders driving change in older organisations.
