The document discusses two approaches to designing user interfaces for business processes: 1) Generating the UI from the process design, which can result in interfaces that are too fine-grained and inflexible for users. 2) Designing the process using BPMN and the user experience using user-centered design principles like personas and scenarios. This allows separating the process logic from the user experience. The alternative approach is demonstrated through examples of an expense reporting system. The result is a user interface that better meets user needs compared to an interface generated directly from the process design. The document concludes that designing both the process and user experience provides advantages like easier maintenance and a better user experience.
