Ford did it with the Model-T. VW nearly went broke for the same reason. Is Microsoft heading for trouble by listening to their customers too much?
Not so long ago, I recall reading somewhere that Microsoft was not going emulate Apple's iPad design, because they had consulted their business clients and they all wanted something that looked like Windows.
This all reminds me of how VW battled to break away from selling the Beetle (Bug if you're American) for much the same reason. All their customers said they wanted one (or something much like one); as many as 90% could say that and still lead a company to terminal decline.
This graph doesn't correspond to a real scenario; plugging in actual market share numbers requires access to stats over a long enough time to do this properly. Nonetheless the basic model applies whenever a company hits a point where it has a very loyal client base and new buyers aren't interested.
Through all this, the company has been maintaining 90% of its loyal clients, yet if this trend continues, they will eventually go out of business. This is what happened with the Beetle (and before it, the Model-T). Increasingly, buyers who had not bought one before saw it as outmoded and uninteresting. Asking the existing client base what they wanted would have resulted in a resounding "more of the same".
This is why Microsoft today asking their clients what they want is to risk oblivion. Ford and VW recovered; will they?
