Quantifying the correlation is easy. You measure the amount of  
resources consumed by UCD. You measure the relative usability,  
consumer satisfaction, or customer engagement (your pick -- doesn't  
matter for the measures) of the resulting products. You plot the chart.

What you get is a scattergram with no clear correlative line. (The  
correlative line would be points clustering on the line itself,  
showing the more spent on UCD, the more the output measures increase.)
