Defects found before release. The performance of the IUS is determined by how accurately it places its payload into position in three-dimensional space. The bull's eye represents the amount of satellite reaction control subsystem fuel required to correct the final orbit. An enlargement of the target center shows that our performance has been in the inner 20 percent of the center of the bull's eye. This is the kind of performance that the customer has come to expect from this organization.
Performance is in the center of the bull's eye.
STS has consistently earned an excellent rating of 97 percent to 100 percent for more than six years. An additional STS goal is to have a motivated and skilled work force, which results from satisfied and productive employees. Before improvements, development was plagued by an ad hoc environment that constantly relied on tiger teams and fire fighting. For example, the formal inspection process improvement increased design by 25 percent, which was 4 percent of the total development effort. This, in turn, reduced the rework effort required during the testing phases by 31 percent.
