The Dignified Mobile Toilets (DMT) case describes how the innovative idea of Isaac Durojaiye, popularly known as Otunba Gadaffi, yielded a lot of socioeconomic and environmental impact and changed the face of sanitary health in Nigeria as well as glamorized what he called “shit business.”

The case gives an account of how Isaac Durojaiye – a graphic artist and a credit card fraud investigator – conceived and built the first mobile toilet in Nigeria by using a 40-feet container. Initially, he had to battle with the lack of patronage, as not a single order came in for the first four years that the wagon toilet was displayed. But Durojaiye was not discouraged because he was involved in security consulting along with the sanitary job. The case recounts how the Founder/CEO of DMT mobile toilets identified social issues (lack of public toilet facilities, poverty, disease, unemployment, crime and so on) in the society and turned it into business success; his efforts helped the development of the social sector in Nigeria. The case also narrates the growth of the mobile toilet market in Nigeria and DMT's market share of this sector.

This case also describes the poor state of public toilet facilities in Nigeria, which forced people to answer the call of nature in open places, thereby polluting the environment and jeopardizing public health.

The DMT marketing strategy and how the company made proper use of the area boys and widows to franchise their toilets was stated. The case also highlights the social and environmental impact of DMT toilets and the company's future direction.

The case will help student see opportunities in the social space and understand that there are business models that provide both social and economic benefits simultaneously.

It is January 2017, and Nikki Tyler, market access advisor at the U.S. Agency for International Development's Center for Accelerating Innovation and Impact, must recommend an actionable strategy for how to use the $10 million contributed by global donors and foundations to scale up the use of chlorhexidine in Nigeria. It was clear that chlorhexidine, a substance applied to newborns' umbilical cord stumps to prevent infection, could reduce infant mortality significantly. However, changing behavior would be an enormous challenge. This case gives students an appreciation for the importance and complexity of global health issues, along with an understanding of key analytic techniques for approaching a complex market situation. Students quickly learn that there are no easy answers to encouraging chlorhexidine's greater use. To develop a plan, it is essential to complete detailed analyses, study insights and motivations, and ultimately compare different possible solutions, considering efficiency and efficacy.
