Adding value to a business process is much easier to define.
But the effects of a business process on society are really important.
Money is a social contract which is universal and fungible. It was designed to be a measure of the value that an individual brings to society and which that individual can redeem from society.
If we lose sight of that fact and focus only on thinking about individual business processes in isolation, then the economy will lose its substance; it will be all smokes and mirrors; and everyone on the planet will end up wasting their lives working on one silly trend after another instead of helping to make actual, lasting progress.
