Discussion
Can we draw conclusions about which system is more maintainable?
- statistically: no
- differences are within confidence intervals for sample
- sample size for statistically meaningful results: 10-25
But, from observations & learning curve data:
- Linux is the least maintainable
- more commands to perform task, baroque naming scheme
- Windows: GUI helps naïve users avoid mistakes, but frustrates advanced users (no scriptability)
- Solaris: good CLI can be as easy to use as a GUI
- most subjects liked Solaris the best
