I hate this advice so much, even if it's true that it works.
How many people actually have any sort of knowledge of (or access to) such measurements? If you're in sales or management, great, but the bulk of the workforce, especially those who desperately need their next resume to land them a half-decent job fast, are not in such positions.
Even as a developer, I've had exactly one gig where I had access to quantifiable results. Customer X was losing $Y per week, and when I provided a solution plugging problem Z... well, that's that. Some customers and employers are rather cagey about leaking finance data. Even if they were wide open about my impact, I'd have to stick around a few extra years to see the result.
