Too much

Roland Rust’s frustration with products that do too much can be summed up in a seemingly simple gift he received recently — a mouse pad.

Rather than the rubber or plastic square that sits on most desks, this was meant to be a better mousetrap mouse pad. It had a clock, calculator, radio, and even a guide on how to use all the gadgets. All of which was too much for Mr. Rust.

“That seemed a bit extreme to me,” said Mr. Rust, a professor of marketing at the University of Maryland’s Smith School of Business. “I was astounded.”

So astounded that he decided to study what he calls “feature fatigue,” often referred to as “feature creep.” He and other researchers at the Smith School found consumers are tantalized by those extra gizmos and functions on products they buy, thinking they make them more useful.

But soon frustration sneaks in, even with the most skilled users. Alienated consumers abandon those products in favor of others that do less better.

It is no longer just the last-night television hucksters (It slices! It dices! It does your taxes!) who are cramming features into their products. With the development of cheap microprocessors that can add functions at little extra cost, Mr. Rust said many consumer goods companies are packing gadgets with extra, sometimes unnecessary, uses. And consumers are more than willing to buy them.

“Too many consumers make the mistake of thinking those added features are great just because they are added features,” he said.

Mr. Rust’s research, written with doctoral candidate Debora Viana Thompson and Smith School professor Rebecca Hamilton, was published in February’s edition of the Harvard Business Review and last year in the Journal of Marketing Research.

The researchers conducted three studies using undergraduate students in groups ranging from 130 to 190 persons. Students were given digital and audio players with varying features, and asked to rate them on factors such as usability and capability. The studies were meant to determine which factors students found important before and after they tried the products.

More students picked the models with the most features, even though they thought the added functions would make them harder to use. When asked whether they wanted to add features, the majority loaded them on. But given another choice after using the souped-up versions, most chose to go back to a simpler model.

Feature fatigue is pervasive, on everything from exercise equipment to televisions. Some prime offenders the Maryland researchers cite are companies that make cell phones and cars, especially luxury models.

Carmakers continue to add options on the dashboard that can distract and confuse drivers, Mr. Rust said. Cell phones, originally just for phone calls, are available with cameras, video functions, Web searching, global positioning, MP3 players and more.

There are some examples of companies that resist the temptation to weigh down their products with extras. Apple’s IPod, for example, is wildly successful because it is relatively easy to use, Mr. Rust said. Google’s home page is bare bones and simple to use for browsers who want to do Internet searches. The company’s other products are found on other pages.

All those extra tools on cell phones don’t necessarily mean the phone is more confusing or less useful, said Laura Marriott, executive director of the Colorado-based Mobile Marketing Association, which represents groups that include wireless device manufacturers and wireless providers.

Adding extra functions can help users find what they are looking for in one phone, Miss Marriott said. New additions and functions are usually tried out first by tech-savvy consumers she labeled “early adopters” and “fast followers,” and are then adopted by the majority of cell phone customers.
