When designing to make a change at the meso level with community groups or service providers, it will be important to think more about how cultural norms, power dynamics, and/or organisational rules/processes can influence interactions. These interactions may be between family or community members, clients and the different providers operating across the same health system. For an intervention to be successful at affecting change at this level, it is critical to be attuned to organizational rules, structural constraints, and the various incentives embedded within a community or set of established relationships, much like you would find at the level of a health care facility. Beyond simply "users" you will need to begin to think more on the system level. With its emphasis on integrating many different and complementary perspectives (including different bodies of knowledge, competencies, professions, stakeholders and interests), service design and strategic design expertise offers tangible ways of developing and managing a truly interdisciplinary collaboration.
