Nimble teams practice kindness. It's an active principle in a culture of trust. Trust matters because it accelerates team alignment and velocity.
Kindness happens in three ways.
People are present to each other, conscious of what everyone considers helpful. People make and keep promises to be helpful to each other. They work from agreements of mutually crafted and tested ways of working together that is helpful to everyone.
Slow teams become nimble by shifting from the opposites of self-serving interest, fragmented efforts and assumptions. They become more clear on what it means to be present, keep promises and work from agreements. Their velocity and alignment becomes stronger. They exceed expectations. Everyone wins.
