- I'm sitting in front of a workstation that has, among other things:
-
- (a) an assembler. (going back 30 rather than 20 years, you'll find a
- time when maybe 70-80% of a project's man-hours were spent
- "coding"...)
-
- (b) several high-level language compilers.
-
- (c) symbolic debuggers, including one that works with an in-circuit
- emulator on the hardware we're developing.
-
- (d) screen-oriented editors and multiple windows.
-
- (e) configuration control software.
-
- Looking through this list I see innovations that increase productivity
- by factors ranging from 10s of percent to factors of 3 or 4.
-
- Conversely, I see management doing things that would look familar to
- someone in management school 20 years ago.
-
- Given the evidence in front of my eyes, it would seem hard to imagine
- that significant improvements in programming productivity have come
- from anything *but* technological improvements in the last two
- decades.
