What's Good for Defense…
How security needs of the Cold War inspired the quality revolution

I'm going to interrupt my series of columns on change management to look at a timely subject: the growth of quality initiatives from the aerospace and defense industries. Most of us know that many high-tech products have evolved from military and aerospace needs, but we may have forgotten how much quality management owes these industries.

After World War II and during the Cold War era, the U.S. government sought to learn from its wartime experiences by mandating rigorous quality standards. Determined to make sense out of a plethora of individual product specifications, the military hit upon the notion of a quality system standard. Such guidelines would provide some level of assurance that good quality was being produced "on purpose." This approach would reduce the need for detailed product inspections by substituting, in part, a detailed evaluation of the contractor's procedures and practices.

The Department of Defense issued the first quality system requirements in 1959 with Military Specification MIL-Q-9858, "Quality Program Requirements," which remained in force until it was replaced by ISO 9000, although it's still "grand-fathered" on many contracts today.

Success, especially in reducing inspection workloads, led to the sincerest form of flattery as other agencies created their own derivatives of the standard. Three years later, the National Aeronautics and Space Administration introduced Quality Publication NPC 200-2, "Quality Program Provisions for Space System Contractors." A nuclear quality system requirement followed in 1969. Soon afterward, NATO developed its own series of Allied Quality Assurance Procedures.

My career as a quality professional paralleled the introduction of such system standards. In 1960, while completing a bachelor's degree in applied statistics, I was interviewed for a job by a retired admiral who was the shipyard superintendent for the General Dynamics Electric Boat Co. in Groton, Connecticut, which was building nuclear submarines for the U.S. Navy. After a short interview, he said, "I have no idea what a statistician is supposed to do, but the Navy's head of quality says I need one, and your paperwork says you are one, so the job is yours if you want it."

With no notion of what a quality control statistician did, I took the job.

A few months later, the same person called me into his office and announced: "I now know why I need a statistician. The Department of Defense has issued a new standard, MIL-Q-9858, which requires a documented quality system. We never had this requirement before, nor have we had a quality control statistician. Ergo, the task of complying with this requirement is obviously yours."

I started this task immediately by differentiating the multiple levels of required documentation (e.g., manuals, procedures and instructions). It quickly became evident that these documents' hierarchical nature was an important feature, so we developed the documentation pyramid.

While we were developing this management system, the U.S. Navy imposed another standard, MIL-Q-21459, specifically developed for the Navy's Fleet Ballistic Missile program. This program, then known as Polaris (later Poseidon and currently Trident), involved launching torpedoes from nuclear submarines that could cruise submerged for as long as six months. Obviously, the requirements for reliability and quality were extremely stringent and the consequences of failure devastating.

One new Fleet Ballistic Missile requirement, for example, was that contractors had to perform stringent internal audits of their processes. So, in 1961 we initiated one of the first comprehensive internal quality auditing programs.

In addition to documentation and auditing, other integral features of military and aerospace standards included management responsibility (specifically, the requirement for a central authority for quality matters, with access to the highest levels of management), corrective action processes, control of purchasing, flow-down of requirements to suppliers and subcontractors, control of measuring and test equipment, identification and segregation of nonconforming product, application of statistical methods, and other requirements we now take for granted. Most significant, the MIL-Q-9858A specification was all-inclusive, stating, "The program shall assure adequate quality throughout all areas of contract performance, for example, design, development, fabrication, processing, assembly, inspection, test, maintenance, packaging, shipping, storage and site installation."

This approach to quality management, along with the many statistical measurement and prediction techniques that aerospace and defense contractors developed to meet emerging requirements of global defense and space exploration, soon migrated to other sectors and became the basis for the ISO 9000-based quality systems and continual improvement processes of the last decade. Indeed, some phrasing and requirements migrated almost verbatim from MIL-Q-9858A, including NATO standards, the British Standards Institute standards, and the first editions (circa 1987) of ISO 9001 and ISO 9002. In short, much of what we do in industry today evolved from the national security needs of the 1960s and 1970s.
