That’s a bit naive way of thinking about it.
If you look at their recent work the answer would be they’re above the point where you’d know them for product.
Big name consultancies now realized the amount of money in building and styling a gadget in general is pretty low. Smart, IDEO, Frog, and the other “Tier 1” design consultants are much more involved in design strategy, brand rethinks, and design challenges that are above a singular product. Which is good, because for what they charge you want to be re-inventing your brand with that kind of money.
Remember that they’re design consultancies, not a product company. Them doing a good job isn’t about you using one of their products. It’s about their clients (giant corporations) being happy.
