This reports the results of a business "benchmarking" exercise in which 41 companies from seven industries were surveyed to determine their current reliability practices. 11 companies were then interviewed.

As with all business benchmarking exercises, the results do not prove whether or not any particular practice is optimal, but rather gives a measure for what industry currently practices and what they see as practicing in the near future. The actual report is relatively brief at 32 pages; the remainder of the report is bulked up with a survey of reliability books in the RAC library, and details about the surveys and interviews.

The summary results of the benchmark (page 29) are that the following are most universally implemented or deemed important (there was a note elsewhere stating that in some cases items deemed important were not actually practiced):


Topic coverage: (*** = emphasized; ** = discussed with some detail; * = mentioned)

*** Dependability Electronic Hardware * Requirements
Safety Software * Design
Security Electro-Mechanical Hardware * Manufacturing
Scalability Control Algorithms * Deployment
Latency Humans * Logistics
Affordability *** Society/Institutions Retirement

Other topics: dependability math, data, common-cause failures, dependability assessment


Abstract:

The Reliability Analysis Center (RAC) conducted a fact-finding, study project to benchmark the reliability practices used by commercial industry. The project was performed for the Office of the Under Secretary of Defense for Economic Security, Weapon Support Improvement Group.

The project consisted of four distinct tasks: a literature search, a survey of the reliability practices of a wide range of commercial companies, personal interviews of a smaller group of companies, and an analysis of the data collected. Based on the results of these tasks, areas of commonality and divergence among commercial reliability practices were identified, as wen as the general commercial approach to designing, developing, and manufacturing reliable products. Four benchmarks and eight Keys to Success were derived from the findings and conclusions. Insights were gained into the motivations behind commercial companies' approaches and their use of military specifications, standards, and handbooks.

The report includes a discussion of Defense Acquisition Reform, a bibliography, summaries of selected documents, and the results of the survey and interviews. In the case of the surveys and interviews, information was treated on a not-for-attribution basis.
