Although the country's industrial development has had a history of only two decades, industry produces a wide variety of industrial and consumer products, including machine tools, ships, computers, automatic telephone exchanges, and television sets (see table 20). Bulgaria was also reported to possess the largest plant in Europe, and second largest in the world, for the production of electric forklifts and similar industrial vehicles. The quality of many products, however, though improving, has not measured up to average world standards. In 1972 the chairman of the Administration for Quality Standardization, and Metrology stated that his organization was confronted with a difficult long-term task of developing an effective quality control system and of catching up and keeping pace with the constantly rising world quality standards. In his view, attainment of these goals required a fundamental improvement of domestic quality standards, effective organizational and technical measures, well-conceived incentives, and an enormous amount of indoctrination of the personnel involved in production. The chairman was confident, nevertheless, that the country's industry would eventually outstrip the qualitative standards of developed industrial nations in the same way that it had succeeded in outstripping these nations' industries with regard to quantitative growth. _Table 20.
