I am seeking for a word to describe coming up with new paths to the same destination. I'm writing about engineers who, among other things, are trying to find new ways to build/create the same things as already exist. For example, they might want to find many new ways to build a pencil, but that end up with the SAME PENCIL at the end.
I've flirted with refinement, but that implies getting better, and they're not always trying to improve the method, just expand and explore new ones.
Other words that seem related: variety, path proliferation, revamping, overhaul... I've even made up a word (I think) "optioning"
I am contrasting this to inventing, as in coming up with a way to make something totally new (like inventing a plane), and exploring, as in combining two things just to see what happens (think of combining two chemicals with no idea of what is going to happen). Then there's this, which is trying to find new ways to make the same thing...
I'm lost. Please help!
