What is protatis?

Answer 1

It seems there might be a typo in your question, as "protatis" does not correspond to any widely recognized term. If you meant "prototyping," it refers to the process of creating an early model or sample of a product to test and validate ideas before full-scale production. Alternatively, if you're referring to "protoplasm," it is the living substance within a cell that contains the cytoplasm and nucleus. Please clarify if you meant something else!
