KV Move

Step 1: Strategic Requirements Analysis & Target Image

At the beginning was a compact strategy phase in which we, within a few weeks, brought together the technical requirements of KV Nordrhein, the framework conditions of the new dispatch service structure, and the needs of the on-call service. Together with two Requirements Engineers, I translated the requirements into core use cases and risks and derived a clearly defined target image for the first version of "KV Move." In this step, central UX KPIs were defined: seamless handling of an assignment, rapid and transparent prioritization according to SmED classification, vital signs and distance, as well as minimizing necessary input steps per assignment.

Step 2: Conception of the Pilot User Flow

On this strategic foundation, I developed a continuous user flow that guides on-call physicians from assignment acceptance through prioritization to billing in the mobile practice management system. Information architecture, navigation concept, and interaction patterns were designed to directly address central KPIs: clear prioritization logic, reduced input complexity, and operability tailored to the usage context in the evening, at night, and while driving to different assignment locations. The result of this phase was a function-oriented pilot prototype based on the defined core tasks.

Step 3: Field Usability Test in Real Operational Context

The pilot prototype was then tested in a field usability study as part of the on-call service. In a shadowing setup, real assignments were accompanied to check whether physicians could handle the central tasks without additional explanations, how well prioritization works in everyday practice, and where unnecessary cognitive load arises. These observations served as a qualitative basis for reflecting the defined UX KPIs and making blind spots from the pure conception phase visible.

Step 4: Iterative Optimization & Preparation for Soft Launch

Based on field observations, the flow, screen sequences, and interaction details were systematically adjusted – with a focus on eliminating critical usability obstacles and further reducing unnecessary steps. This resulted in a consolidated design version that brings together the requirements of KV Nordrhein, the work reality of on-call physicians, and the previously defined success criteria and served as the basis for the soft launch with a limited number of participants.
