Workflows about any process

Hey folks!

How about an app to desing workflows for anything that needs to go from point A to point B, with each node having capacity / constraints for validation. Examples would be Manufacturing processes, Cooking recipes or even Software flow diagrams all designed for rapid prototyping and iteration.

What do you people think of this idea? How would you use it, or are you using anything similar at the moment? It would help me finalize on the requirements and design to know more real world use cases.

One could think of setting up a constraint that flows through multiple nodes, until it reaches a destination node where the thing being "cooked" is done.

Thanks in advance!
