Safety NASA definition

Commonly used NASA definitions of basic system safety terms include... 

Patient Safety Reporting System (PSRS) (6) A prototype blameless reporting system established in 2000 by NASA and the Veterans Administration. The PSRS emphasizes the reporting of near misses (see definition above). 

A study conducted by the U.S. National Transportation Safety Board reported that 73% of accidents were due to flight crew failures rather than technical-related problems [10]. Furthermore, the studies conducted by National Aeronautics and Space Administration (NASA) (in the form of pilot interviews, simulator observations, and accident analyses) reported that there was a definite need for more focus on team work and communication of pilots including command, decision making, and leadership [3]. Furthermore, the studies revealed that the crew factors such as the attitudes of the team toward communication and coordination, command responsibility, and recognition of stressor effects affect safety performance.
