Process vs Product: Which is More Important?

Everything and everyone in the world is a product of some sort and have to go through a process, but which is more important, the process or the product?

A process is the time and effort spent to achieve a product. A product is what we can say, the "fruit" of the process that made it. When we eat a fruit, do we care anything about how it was formed? Of course not. If we find a worm in the fruit, we do not think how the worm went in. We would just throw the fruit away, stating it as a bad fruit. It's the same with a product. In school, it is your grades that count, not your learning experience. In work, it is your salary that counts, not your labor. In other words, people look at your product, not your process.

For example: Newater. What is Newater? It is actually sewage water gone through treatment. The first step is the conventional wastewater treatment, where the wastewater is treated in the water reclamation plants to make it safe to be ejected into sea. Then microfiltration removes most suspended solids and microorganisms. Reverse Osmosis is then used to remove trace metals, soluble matter and some more microorganisms. At last, ultraviolet light is used to disinfect the water just as a safety precaution and the addition of some alkaline chemicals to restore the pH balance. Nevertheless, why do we care about the process? The water is clean and pure. That's all that matters to me. I'm ready to drink it anytime. The knowledge of the process of wastewater going through all these treatments does not dictate the fact that Newater is crystal clear and very clean.
