Es inventado, por supuesto, pero se basa en un memo de Microsoft (http://edge-op.org/iowa/www.iowaconsumercase.org/011607/0000... Allí explican que hay dos tipos de clientes:

• Depth customers requite full functionality. They use (or wish to use) a persona/computer to be more productive: to complete their task(s) faster, with higher quality, or perhaps some other dimension of productivity. For the benefit of added productivity, depth customers require many features ("product depth"), and they are willing to pay a higher price for software. They prefer easy to learn software, but they are willing to incur some additional learning time for the added productivity benefits of software with depth.

• Breadth customers require simplicity. They are also interested ha improved productivity, but
generally they don’t have specific or well-defined ideas of how computer usage will improve their productivity. They are less likely to value or desire high functionality, and thus, they will tend to be more price-sensitive than the depth customer. Over time, we believe many of the non-depth customers will enter into at least one of the depth segments.

Entonces tenemos los conceptos complementarios de profundidad y amplitud.

Los otros serían los "clientes que buscan/requieren amplitud de funciones."

Atentamente,
