A safe environment for taking risks without fear of embarrassment or criticism is one of the characteristics of a high-performing Agile Team. A high-performing Agile Team is a cross-functional group of people that have everything, and everyone, necessary to produce a working, tested increment of product1 They are empowered, collaborative, aligned, and committed to delivering value to the customers and the organization2 One of the factors that enable a high-performing Agile Team is a safe environment where team members can experiment, learn, and grow without fear of failure, blame, or judgment3 A safe environment fosters a culture of innovation, creativity, and continuous improvement, as well as a sense of psychological safety, trust, and belonging among team members4 Team C is demonstrating this characteristic by creating a new workflow to speed up the testing process, even though it did not work out as expected. The rest of the team was excited to hear what was learned from the failed experiment, rather than being disappointed or critical. This shows that the team values learning over perfection, and supports each other in taking risks and trying new things. (Must be taken from SAFe 6 Scrum Master resources) Reference:
