If analysis leads to actions
There are some companies who use big data systems solely so they can tell their clients that their services need big data systems. Equally some use the technology because if their employees thought they were working in yet another low-end service shed, they'd go and find somewhere more CV positive to work.
On the other hand, you can find yourself working on a project where the company behaviour is sufficiently well characterised (MVT et. al.) and the product sufficiently data-led (e.g. large volume online sales) that you can plot a straight line between insight and action, and then close the loop with feedback on sales uplift. At that time, yes you can realise value. If you are unable to identify what you are going to change as a result of the vague insights you hope you might get, or if you are unable to measure the difference between your approaches, then big data (however you define it) is not going to pay its way.
