1970 to 1979: Computers and Software Begin Creating Wealth - The Technical and Social History of Software Engineering - page 169

This decade, one of explosive growth of software in all industry segments, also
witnessed IBM's rise to become one of the world's major providers of computers
and software. Table 6.1 shows the approximate numbers of applications during this
decade.

Function Points in 1975
Function points were invented by IBM in White Plains by Al Albrecht and col-
leagues circa 1975 and were published outside of IBM in 1978.
Formal inspections were developed by IBM during this decade by Mike Fagan,
Ron Radice, and colleagues in IBM Kingston. During this decade, IBM pioneered
dozens of software engineering technologies and established an excellent reputa-
tion for quality and reliability of both hardware and software.
For the same application of 1,000 function points, the results would be the fol-
lowing:
• Source code statements for 1,000 function points: 91,426 logical code
statements
• Programming language: C
• Reuse percentage: 0% to 10%
