Book excerpt: The Flow System Guide provides a brief description of The Flow System along with descriptions and characteristics of the different methods, techniques, and tools listed for each of the three helixes that make up the Triple Helix of Flow (complexity thinking, distributed leadership, team science). The Flow System provides a set of methods for organizational leaders and practitioners to utilize when dealing with complex problems and environments. As organizational leaders are slowly realizing that current best practices will not work well when dealing with complex issues, The Flow System offers a set of methods, techniques, and tools that have been shown to work well in complex environments.Flow is achieved in an organization when employees and team members are free to interact, adapt, learn, and evolve in a way that allows them address threats (internal and external) that is uninterrupted by inhibiting constraints. Flow is best described in The Flow System as the seamless transition, from ideation to delivery, through the interconnectivity of complexity thinking, distributed thinking, and team science. Each of the three helixes must be utilized before an organization can achieve flow. Addressing only one of the helixes will result in suboptimal performance, all three of the helixes must be utilized.The Flow System Guide provided here is also available online at https: //flowguides.org/index.php along with six or more translations of The Flow System Guide
