Design for Assembly: The Cheapest Part Is the One You Deleted

Design for assembly is defined in C4.1.1. What matters here is the single move that does most of the work: get rid of parts.
Every part carries a hidden tail of costs: it must be designed, tooled, bought, stored, counted, moved, picked up, oriented and fitted, and each of those steps can go wrong.
So the test for every component is: does this part move relative to its neighbour, does it have to be a different material, and would the product be impossible to assemble without it? If all three answers are no, it should be merged into the part next to it.
A part you deleted costs nothing, weighs nothing, and cannot be fitted the wrong way round.

Key Principles

Minimize Part Count
1. Fewer Parts: Reduces assembly time and potential for errors.
2. Standardization: Use common parts across products to streamline production.
