Routing variability (RV) survey, this is sometimes known as high-mix, but high-mix can also mean products with the same or similar routings (manufacturing process sequence) with many different finished SKUs. For example, products can go through the same process, but have different raw materials, operation variances, or final test results and end up with different part numbers.
We specifically want to characterize the company based on manufacturing routing variability and not necessarily SKU variability.
Metric for routing variability within a company:
(# Routings / # Products) * 100 - this measure would be 100 if each of your products have a unique routing and would approach 0 if you have many products and few routings.
