It's changing the way we work, manufacture, communicate, entertain ourselves, manage our health, money, fitness, and more. Smart software is embedded in so much of what we do and use in today's digital world. But I believe that this presents us with a real problem in terms of quality. Because the actions and responses of intelligent machines will differ over time and thus are less predictable than traditional IT-systems. And also, because the manually intensive way we've developed, tested and delivered software up until now, is no longer enough to meet the escalating demand for new and innovative applications, in every walk of life.
