When someone says "can we..." or spills their idea they've often identified a real need but they often don't seem to do any sort of analysis further than identifying a demand signal.

In my experience, they've identified a want. Either their want or a want they think the market has.

It's not until further analysis do they / you / we get to root need(s). This is why (allegedly) so many "IT projects" fail. The client got what they wanted...not what they needed.
