Can we solve big public problems anymore? Yes, we can. This provocative and inspiring book points the way.

The huge challenges we face are daunting indeed: climate change, crumbling infrastructure, declining public education and social services. At the same time, we've come to accept the sad notion that government can't do new things or solve tough problems—it's too big, too slow, and mired in bureaucracy.

Not so, says former public official, now Harvard Business School professor, Mitchell Weiss. The truth is, entrepreneurial spirit and savvy in government are growing, transforming the public sector's response to big problems at all levels. The key, Weiss argues, is a shift from a mindset of Probability Government—overly focused on safe solutions and mimicking so-called best practices—to Possibility Government. This means public leadership and management that's willing to boldly imagine new possibilities and to experiment.

Weiss shares the three basic tenets of this new way of governing:

• Government that can imagine: Seeing problems as opportunities and involving citizens in designing solutions
• Government that can try new things: Testing and experimentation as a regular part of solving public problems
• Government that can scale: Harnessing platform techniques for innovation and growth
• The lessons unfold in the timely episodes Weiss has seen and studied: the US Special Operations Command prototyping of a hoverboard for chasing pirates; a heroin hackathon in opioid-ravaged Cincinnati; a series of experiments in Singapore to rein in Covid-19; among many others.
