Computers were doing more and more for enterprise and the expense of 'bugs' in software was causing lots of concern and slowing automation of data processing. What should have been economical was in many cases very expensive and owners and managers were skeptical of the whole idea of computing. The New York Times database in the late 60s, a new use of computing, was one of the first projects brought in on time and under budget using Structured methodology. Programming had prior been an Art in which some were more or less skilled and which others wondered about. Later versions of most languages added features for Structured Logic.
Most newer languages have structure implicit in their design.
