3. It should allow for concurrent execution of programs so as to enhance speedy processing of data.
4. Operating systems should handle interruptions caused by program abnormalities or machine failure and be able to report this to the user.
5. System security is inherent to any operating system as all security routine checks are controlled by the operating system.
6. Ease of use or need for basic training.
7. Portability of the program from one system to another.
8. Speed and productivity of the software.
9. Its cost of maintenance.
