Process Selection
Strategic importance relates to the potential for a process to impact the organization's goals. The health of a process is an assessment of the degree to which a process might be improved along one or more measures of performance (e.g., cycle time, cost, quality, or flexibility). Other factors equal, we should focus our efforts on the most feasible changes.
