SharedAir: A novel cocreation framework

The proposed SharedAir is a harmonized, human‑centred co‑creation framework designed to guide the participatory design and validation of the MULTIPULM digital health ecosystem for chronic respiratory care (https://www.multipulm.eu/). It structures co‑creation into three iterative cycles (i.e., Shared Understanding, Shared Design, and Shared Validation), embedded in agile sprint logic from early exploration to minimum viable products. Standardized session and reporting templates ensure methodological consistency across components and stakeholder groups, while a metric suite combining UX indicators, the Net Promoter Score (NPS), and the Quality of Innovative Thinking (QoIT) supports evidence‑based design decisions. Applied to MULTIPULM tools such as breathing games for individuals with chronic respiratory conditions, SharedAir intends to enable systematic elicitation of user needs, collaborative design of mechanics and interfaces, and iterative validation of usability, engagement, and adoption likelihood. Compared with existing co‑creation and user‑centred design approaches, it advances multi‑component digital health projects by integrating agile sprints, innovation scoring, and clinical workflow alignment within a single, comparable framework.
