Reliability is the likelihood that a product or system will perform satisfactorily for a given period of time. 

Here are some steps to ensure data accuracy and reliability in TQM:
Define data requirements
Collect data systematically
Validate and verify data
Analyze data effectively
Improve data continuously
Review data periodically 

Reliability can be achieved by overdesign. For example, using large factors of safety can increase the reliability of a product. 
The formula for calculating the overall reliability of a system is R = (1-F1) * (1-F2) * (1-F3) * (1-F4). R refers to the overall reliability of the system or asset. 

Total Quality Management (TQM) is a quality control methodology and tools that became known after Deming lectured on statistical quality control during Japan's rebuilding efforts following World War II.
