The article focuses on the need for engineering influence upon accounting procedure. Economy studies are universally acknowledged an essential part of engineering. Because of the large number of decisions made at the research, development and design levels, economy studies performed by engineers are collectively of great moment to corporate and national prosperity. It should be obvious that the accuracy of an engineering economy study can be no better than that of the data on which it is based. An improvement of the basic data is sometimes urgently needed; it can be accomplished at justifiable expense, but will require a mutual effort to build and maintain an adequate two-way avenue of communications between accountants and engineers. Accountants are currently striving to make one set of accounts serve two incompatible purposes that is, to provide records acceptable to officialdom and to provide sound business data on which to base everyday business decisions at the grass-root level. The latter aim is often neglected, unless the scope of the accounting profession is expanded into two parallel sets of accounts.
