The valley of tears - Elisabeth Kübler-Ross' change curve

Swiss-American psychiatrist Kübler-Ross created the grief curve in 1969. It captures the five stages of loss and which types of emotions mourners experience. This framework was so potent that it's widely used as the change curve as well. Discussing the change curve and admitting one's emotions during a transformation helps everyone come to terms with the impact of a change. It's a potent tool.
