Estimation is a practice that is embedded in most management practices. Leaders around the world need alternatives to estimation because of estimation's reliance on the human inability to predict the future. Additionally, portfolio level decisions require evaluating many (n>>1) alternative scenarios. The "what if?" questions needed at that level can not be adequately answered with estimation as a practice. In software, this is even a bigger problem. We need an alternative to estimation based portfolio management, and this talk aims to contribute to that knowledge development in the community of software-powered product development.
