“The process by which most enterprise software is developed is fatally flawed. There are flaws in any software development process, but in the past 13 years I’ve seen one approach produce more bad software and blow more budgets than any other: requirements-driven software development. Thankfully, I’ve also had the opportunity to see the success of an alternative type of process, a process in which user experience design drives what gets developed. This type of process helps teams deliver good software on time and within their budgets.”
