Scrum is like a house, where the team can be safe and self-organize. They will build trust and continuous improvement. Respect Scrum team as an ecosystem will help the team evolve and build up teamwork, and the values will come Day by Day, Sprint by Sprint.
In every Sprint, Sprint Retrospective is an excellent chance to inspect and adapt the way of working. There are many formats to help Scrum Master facilitates the Sprint Retrospective. But I always think about the format that can focus on the team environment, the ecosystem. I keep thinking and uphold that idea, and I found the inspiration from the "Parable of the Soils”. Borrow that parable; I create the Sprint Retrospective format “The 4 Soils”. The meaning of this format is to focus on how to help the Scrum team define what is the good/ bad impact to the house o of Scrum. From that, team will have the action or change to improve/ maintain the ecosystem.
