Most people fail to make it and that’s why the PMP pass rate is minimal. In relation to the previous two comes the third cause: lack of strategy. Most candidates have little time to study, either for work, family, etc.
WebInitially the designer allocates failure rates to sub-system assemblies. When a detailed design exists, more accurate MTBF calculation must be conducted to verify compliance with the requirement. Finally, during field testing an MTBF demonstration takes place by accumulating field failure data. How MTBF is calculated:
