Delivering software one 1 Feature at a Time (1FaaT™) is a challenge for established organisations. And yet they must do so as newer digital competitors engage their markets through ongoing experimentation of customer value. The tools and processes are well understood, but how people behave and interact with one another explains why older organisations are slow to change. This presentation articulates ‘what good looks’ like for an organisation’s culture and identifies 10 behavioural blockers that need to be addressed. The presentation is based on a soon to be published book titled One Feature at a Time (1FaaT™).
