With today's changing environment, meeting project commitments can be challenging. The Flight Projects Directorate at NASA's Goddard Space Flight Center (GSFC) has a portfolio of over 60 missions in various stages of the space flight life cycle. Numerous methods and approaches are used to monitor and track project performance and utilization of tools can provide valuable information to help manage missions. However, challenges can arise when these approaches are viewed as the sole data point for assessing the project status. At GSFC, performance management metric-based tools have provided insightful information for evaluating the programmatic health of space projects. These tools have provided the awareness and foresight desired to effectively manage and meet commitments, which is tremendously beneficial on the road to achieving mission success.
