For each of our target audiences we identified the design criteria. The design criteria provides the framework for designers to brainstorm and create prototypes that align with the needs and preferences of the target audience.
Below are the design criteria for our ‘typical family’.
Easy to clean
No smell and enough space to move around, read news, stand-up and open door
Lifespan of 4-5 years
Can self-build but willing to have some parts purchased
Child-friendly and safe to use – hole not too big
Not ecosan – do not want to handle waste
Low cost
Beautiful
