There was undoubtedly waste in the construction of the Apollo launch facilities and in the launch operations, but we are not in a position to judge the cost efficiency of the KSC team against similar projects, such as a large defense contract. In our personal view it was a noble goal, nobly achieved. A word is in order with regard to Kennedy Space Center speech usages, especially acronyms. The scientists and engineers at KSC do not use a peculiar tongue to mystify the layman - but as a matter of fact, that is one result. Module is an example.
Interface is another word that was recast at the space center.
Perhaps this was subliminal recognition that Kennedy Space Center was the Great Interface where the many parts and plans that went into the moon launch had to be fitted together. Like all government agencies since 1950, NASA made extensive use of acronyms. In February 1971, the Documents Department of the Kennedy Space Center Library compiled a selective list of acronyms and abbreviations. It contained more than 9,500 entries. The astronauts were quick to acknowledge that Apollo was a team effort.
