Abstract
A Review of the Impact of Inspection on the Quality Assurance and Reliability of Project, Manufacturing, Operations and Maintenance is reported. The types of inspections and methods of establishing the frequency of inspection have been identified. It has been revealed that too little inspection leads to greater rejects (out-of-limit works) and too much inspection leads to loss of revenue due to the cost of excess inspections. A compromise has therefore been established between cost of out-of-limit work and cost of inspections. This eventually led to the formulation of the optimal value for the Change Multiple in frequency of inspection of projects, manufacturing, operations and maintenance. This optimal value of frequency of inspection yielded the optimal value added to Quality Assurance and reliability of projects, manufacturing, operations and maintenance.
