A number of the failures related to project management according to the report of the subsequent investigation. There was one cause of the space probe loss that hit the headlines: two teams involved in the space probe development were using different systems of measurement – one was using meters, centimeters and kilograms, the other was using feet, inches and pounds. However, the wide-ranging investigation into the failure came up with a number of other contributing factors: As a result, the culture of ‘Faster, Better, and Cheaper’ was replaced with ‘Mission Success First’. Actions taken subsequently for another project, NASA’s Mars Polar Lander, included: A new sen
ior management leader was assigned There was inadequate risk management and issue control. The report recommended that future projects should conduct continuous risk analysis and discussion of issues from start to end of the project. NASA needed to foster a climate in which issues could be easily raised. Minimizing risk was also behind recommendations that in future NASA should plan long-term for a different type of technological innovation, focusing on smaller, low-risk products that could then be incorporated into wider projects. Clearly in this type of scientific project, there is little leeway in project outcomes and margins of error are small. The project had failed to set clear success criteria for the project outcomes. The scope of the project had not been matched to the funding, leading to inadequate funding for defined outcomes. The project was judged to be lacking in good team working and adequate and appropriate staffing. The problem was found to be poor communication between, rather than within, different teams. In particular the report called for better monitoring of the work of contractors. Better trained personnel were required, and project management courses were part of this recommendation.
