Guttman transforms the way people show up and work together: how they lead, make decisions, perform, and manage conflict. People become accountable not only for their own success, but for that of their peers and even their leader. They begin to achieve breakthrough performance. The result is swift and significant: horizontal, high-performance teams and organizations that are less top-down and hierarchical, work cross-functionally, confront and resolve issues openly, make decisions fast, and are fiercely competitive. Building high-performing, horizontal teams and organizations is the most effective way to bring about fundamental change, achieve rapid results, and gain long-term competitive advantage. Since 1989, we have worked alongside clients to transform team and individual performance, redefine how decisions get made and executed, and reframe how functions and individuals interact. We have put to work a proven process—supported by expert consultants, facilitators, and coaches—for hundreds of clients, including Fortune 100 corporations, mid-sized companies, entrepreneurs, and non-profit organizations. Many of our clients are industry standouts who retain us not because they are under-performing but because they seek to over-perform. As industry leaders, they know they must do more to outdistance competitors. Other organizations engage us because they are convinced that they must take up their game. Some have reached a plateau and can’t go higher because they are unable to harness existing talent and capabilities. They possess great individual resources, but misalignment, internal conflict, and silo thinking create dysfunctional teams unable to produce standout results.
