Changes to the environments in which we work, study, and live can often provide leverage for improvements in performance. Production of products and services takes place in some type of work environment. As we try to improve quality, reduce costs, or increase value of these products and services, technical changes are developed, tested, and implemented. But many of these technical changes do not lead to improvement because the work environment is not ready to accept or support the changes. Changing the work environment itself can be a high-leverage opportunity for making other changes more effective.
