When we can go for system improvement ?
- consistency that must be sustained all the time (so the input and output layout must stay the same).
- more processing speed (you may get more output and ultimately more efficient and effective)
- low error rates (Should an end-user encounter an error, they must be shown how to fix it.)
Well, a system is improved if the processing capability of it is changed in a way that makes it better.
