“The famous tree swing picture (also known as tyre swing, tire swing, rope swing) depicting tyre (or tire) and rope swing in various states of dysfunctionality, illustrates the pitfalls of poor product design, or poor customer service, and the dangers of failing to properly listen to customers and interpret their needs. The tree swing also demonstrates the dangers of departmental barriers, and failures of departments to talk to each other, and to talk to customers. As such, the tree swing is perfect for training these areas of quality, communications, customer care and inter-departmental relations. If you are using the tree swing to highlight a training subject most people very readily interpret the pictures into their own organisational situations. Some tree swing discussion points are at the foot of the page.”
