Continual Service Improvement
Everything in nature is bound to improve, although some improve in leaps and bounds and some more gradually. If something or someone doesn’t improve, they wither and die. Take, for example, the theory of evolution. Certain characteristics have changed in us and in other living things over successive generations. They have always changed for the better, with successive generations bettering from their parents and forefathers in adapting to the environment. Mutations and genetic drifts are other improvements that are a result of evolution. So, in effect, we have survived all these years and will survive for years to come because we have improved and continue to do so.
