Enterprise User Experience (EUX) involves the application of research and design theories and methods to build and improve software used by employees in businesses. This type of software is typically highly complex and built for diverse, but specialized users. Common examples include project management, customer relationship management (CRM), and enterprise resource planning (ERP) systems.
Unlike consumer applications, enterprise software is often locked up behind firewalls, and rarely ever seen by the public. As a result, EUX may lack some of the wow-factor of working on disruptive consumer apps like Airbnb, Spotify, or Uber, but it is no less important, and arguably more so.
The argument for why it is more important is that operational effectiveness is the key to the success of all businesses, and increasingly, software plays a role in that process. Furthermore, if a business is to create and support amazing consumer products, it will almost certainly need numerous enterprise software applications to manage the process.
