For decades, designers and businesses have created personas of their target audiences-fictional character documents based on interviews and research that summarise customers with similar needs.

Non-human and non-user personas enable designers, innovators, and decision-makers to also represent the needs of environments, animals, and invisible humans impacted by product lifecycles and business ecosystems.

Using non-human and non-user personas is new, however, so their use is low and best practices are still evolving.

The Non-human Persona Guide synthesises learnings from designers from around the world into methods for identifying, creating, and using non-human and non-user personas to expand human-centred design to be 'more than human'.

BONUS

The Non-human Persona Guide is accompanied by a virtual Journey Backpack, containing design tools and resources to implement the method, available at https: //lifecentred.design.
