Answer:
a. Reduced Risk and Reduced Cost.
Explanation:
A software such as an operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.
Re-engineering a software system has two key advantages over more radical approaches to system evolution:
a. Reduced Risk: this is simply because redeveloping a software poses a high risk to the business organization or individual due to developmental issues or errors.
b. Reduced Cost: the process of re-engineering is usually cheaper for businesses.
