12.2. Figure 4 is a generalized model of a mission system. There is significant overlap between Man,<br />
Machine, and Media, because these elements interrelate directly, but the critical element is Management<br />
because it defines how the other elements interact. When a Mission is unsuccessful or a Mishap occurs,<br />
the system must be analyzed: the inputs and interaction between the 5-Ms must be thoroughly reassessed.<br />
Management is often the controlling factor in mission success or failure. Military safety centers and the<br />
National Safety Council cite the management processes in as many as 80 percent of reported mishaps.<br />
12.3. Successful missions, or mishaps, do not just happen, they are indicators of how well a system is<br />
functioning. The basic cause factors for mishaps fall into the same categories as the contributors to<br />
successful missions—Man, Media, Machine, and Management.<br />
12.3.1. Man. Area of greatest variability and thus the majority of risks.<br />
12.3.1.1. Selection: Right person psychologically/physically, trained in event proficiency, procedural<br />
guidance, habit pattern.<br />
12.3.1.2. Performance: Awareness, perceptions, task saturation, distraction, channelized attention, stress,<br />
peer pressure, confidence, insight, adaptive skills, pressure/workload, fatigue (physical, motivational, sleep<br />
deprivation, circadian rhythm).<br />
12.3.1.3. Personal Factors: Expectancies, job satisfaction, values, families/friends, command/control,<br />
discipline (internal and external), perceived pressure (over tasking) and communication skills.<br />
12.3.2. Media. External, largely environmental forces.<br />
12.3.2.1. Climatic: Ceiling, visibility, temperature, humidity, wind, precipitation.<br />
12.3.2.2. Operational: Terrain, wildlife, vegetation, man made obstructions, daylight, darkness.<br />
12.3.2.3. Hygienic: Ventilation/air quality, noise/vibration, dust, contaminants.<br />
12.3.2.4. Vehicular/Pedestrian: Pavement, gravel, dirt, ice, mud, dust, snow, sand, hills, curves.<br />
12.3.3. Machine. Used as intended, limitations, interface with man.<br />
12.3.3.1. Design: Engineering reliability and performance, ergonomics.<br />
