Gorbachev recurrently employed the term "perestroika", first used publicly in March 1984. He saw "perestroika" as encompassing a complex series of reforms to restructure society and the economy. He was concerned by the country's low productivity, poor work ethic, and inferior quality goods; like several economists, he feared this would lead to the country becoming a second-rate power. The first stage of Gorbachev's perestroika was "uskoreniye" ("acceleration"), a term he used regularly in the first two years of his leadership. The Soviet Union was behind the United States in many areas of production, but Gorbachev claimed that it would accelerate industrial output to match that of the U.S. by 2000. The Five Year Plan of 1985–90 was targeted to expand machine building by 50 to 100%. To boost agricultural productivity, he merged five ministries and a state committee into a single entity, Agroprom, although by late 1986 acknowledged this merger as a failure.
