" All groups and organizations need to know how they are doing against their goals and periodically need to check to determine whether they are performing in line with their mission. This process involves three areas in which the group needs to achieve consensus leading to cultural dimensions that later drop out of awareness and become basic assumptions. Consensus must be achieved on what to measure, how to measure it, and what to do when corrections are needed. The cultural elements that form around each of these issues often become the primary focus for what newcomers to the organization will be concerned about because such measurements inevitably become linked to how each employee is doing his or her job.
