The purpose of capability growth index is to give designers and development managers an early heads-up as to where they stand in achieving the metric under scrutiny, such as MTBF. The Capability Growth Index measure is based on the widely used quality process capability indices, Cp and Cpk. The problem reliability practitioners have in the area of design for reliability is that the major reliability...
Too often, the reliability engineering effort is an after-the-fact activity on a program. The support engineering disciplines, such as reliability and supportability engineering, are often found added-on to the tail-end of the design effort. In order to maximize operational effectiveness within today's cost and schedule constraints, reliability engineering needs to be a part of the up-front systems...
For years, organizations such as the government, have been trying to improve product and system reliability by specifying MTBF (Mean Time Before Failure) as a TPM (Technical Performance Measure). Yet, looking at papers and presentations from NASA on Ultra Reliability and ATRIP (Army Transformation Reliability Improvement Program) from the Army, system reliability has been declining. More and more...
