Research through online articles, scholar studies, and online videos has led me to think the controlling issue of the poor sanitation in Kibera slum, of Kenya, is the money problem - Kibera residents are extremely poor, low employment opportunity and low wage earning (something like 1-2 US dollar per day). The hard earned cash is spent on priority essential needs, first is Rent (land/home is not privately owned), second Clean water (are expensive due to low supply & high demand), third is food (even this basic need is difficult to obtain) - therefore what money is left (if there is any), is not enough for medical treatment and sanitation service. Therefore, the local resort to open defecation and perform the 'flying toilet', and parents are unable to afford the available medicals to treat their ill-child. That is why child mortality is high in Kenya, because the family don't have the money.
The issue is significant that design thinking is necessary to develop product-service-system and create solution that can allow affordability and a sustainable process to collect and dispose human waste, for the Kibera residents.
Tutor comment:-
Tutor - The product need consideration of material choice, texture, and a refine form to speak of its multi-purpose in storage, composting, fertilising, and planting. There needs a more close interaction between the product and the service system, e.g. a collection action. The container should considered to be stackable for sustainable transportation of the supply. Imagine how proposed NGO's can have closer relationship with the end-users, e.g. supply of seedlings, plants, information, education, and aid.
Reflection:-
There is a need to bring closer relationship between the product and service, with more refinement in the product especially texture, colour, and material. Poster system diagram can be improved and look at other student's work as examples.
