Spending time “in the zone” means being fully immersed in a task that is challenging, engaging, and enjoyable. This state of flow is associated with higher levels of creativity, innovation, and performance1. According to SAFe, optimizing the time spent in the zone for individuals and teams makes a substantial difference in ART productivity2. The other options are not directly related to the concept of flow, although they may be influenced by it. Reducing queue lengths, refining productive collaboration, and making work in process visible are all aspects of visualizing and limiting WIP, which is another flow accelerator3.
