In an episode of The Critical Path, Horace Dediu and Bob Moesta discuss cognitive ethnography and user research (they call it "Job To Be Done research") in the context of Apple. He hypothesizes that Apple will be less successful if they enter the enterprise market because they will be forced to take the concerns of the buyer into consideration, as opposed to the user. This is a common refrain when people talk about user experience and enterprise products, "the design must be compromised in order to impress the buyer." I've heard this from both other designers and people telling me directly as an excuse for why we need to build something a certain way.
It's true that an incredible amount of knobs and a long feature list are usually all a manager wants to look at when paring down a list of vendors/products. But it's also true that users traditionally had little to no voice at the table. Today, we see users becoming more vocal and even passionate about the tools they use. This is a result of great design in tools that have traditionally sucked. See Mailchimp, Wufoo, Github, analytics tools of all kinds, Square. All of these, while not exclusively enterprise, have many enterprise and small business users (and therefore buyers). You can be sure that if a user of one of these products moves to another company, they will complain pretty loudly if they are forced to use some piece of shit that makes their life impossible. Once users get used to to an iPhone, it's hard to go back to a Blackberry.
Bad analogy? Actually, that's exactly what's happening in many enterprise companies today. Horace calls it the "consumerization of IT." Users bought iPhones. They like them. They like them so much, they really don't want to deal with a Blackberry at work, they just bring their iPhones instead. They connect to corporate networks, open work documents, email, text, and use apps that access business data. IT departments are now scrambling to find solutions for this non-compliant behavior and find a way to officially support personal devices in the workplace.
If the pattern continues, Horace predicts that, while Apple may not be as successful in enterprise at first, they will eventually be smuggled and forced onto enterprises by users as a result of their superior design.
Ultimately, this is the result of making people love your product. Users determine who wins, not buyers. Make people love your product and company. This is not something you can do on your own; your entire team must have a common value system and genuinely care about about the people they serve (and I don't mean the boss). If your team doesn't share a common value system, it's really really hard to instill one. Man, it's hard.
