NASA’s Goddard Space Flight Center has developed a method to collect suspicious data and analyze them without extensive costs. A common challenge in complex computer systems is the identification of unauthorized use, which can be...

A complex project having many tasks and sub-tasks, many phases, and many workers will often require an evaluation of completion of the tasks and sub-tasks at several times during the project’s duration. Initially and throughout the duration, suitability of the technical and inter-personal characteristics of the...

The NASA Exploration Systems Mission Directorate (ESMD) IRKM-P tightly couples risk management and knowledge management processes and tools to produce an effective “modern” work environment. IRKM-P objectives include: (1) to learn lessons from past and current programs (Apollo, Space...

A computer program implements a methodology, denoted probabilistic risk reduction, that is intended to aid in planning the development of complex software and/or hardware systems. This methodology integrates two complementary prior methodologies: (1) that of probabilistic risk assessment and (2) a...
