Success-vs-Failure is a journey rather than a destination.
There are three different approaches for Success-vs-Failure:
Success-OR-Failure:
This approach is fault-tolerant.
There is no space-time relation between Success-OR-Failure.
Success-AND-Failure:
This approach is mistake-proof.
There is common-space between Success-AND-Failure.
Success-WITH-Failure:
This approach is error-free.
There are common-space and shared-time between Success-WITH-Failure.
