Abstract :
Drawing on extensive data from the NASA Space Shuttle´s guidance software, the author proposes a method for evaluating the effectiveness of legacy software maintenance efforts. He provides several formulas for tracking maintenance stability, defined as increasing functionality with decreasing failures over time, and offers data that supports their validity. He also provides tips for applying his formulas to different projects
