Almost every company brings innovative ideas to market somehow. But too often, big breakthroughs happen accidentally, requiring individual heroism and a heavy dose of serendipity. How can companies make that process reliable and repeatable without undertaking major organizational changes? The solution: Creating a "minimum viable innovation system"—the most basic building blocks for an orderly innovation function. The MVIS concept is inspired by the lean start-up movement, where a "minimum viable product" allows entrepreneurs to design and launch new concepts and gain insights quickly. With limited investment and resources, an MVIS can help organizations make tangible progress in increasing the predictability and productivity of critical investments in future growth.
