Lead time of scientific discovery and its applications is much shorter in developed countries. This is because of their constant efforts of research and development for technology upgradation which was lacking in our country. Aluminum was obtained in pure form in 1825 and it was only in 1886 that large scale production process was finalized. Here lead time is 60 years. Hydrogenation of oil in the manufacture of Vanaspati originated in 1905 and by 1911 Procter and Gamble Company, USA placed hydrogenated cotton seed oil, similar to vanaspati on the market. Here the lead time is only 6 years. Lead time depends on the state of industrial development of the nation and priority given by the nation to that particular industry.
