Bringing the voice of the end user into the product design at the earliest stage

Engineering students, Oxford University

Recently, I was invited to talk to a group of Oxford University engineering students about solar cookers. I am not an engineer nor qualified to speak on technical issues, but I felt that I could be a voice for the beneficiaries in developing countries. A key to the success of a product is the early involvement of the intended end user in the design process.

I often visit my family in Kenya. My relatives in Nairobi welcome me with a traditional meal of chicken, beef, vegetables, rice and ugali. The food is cooked by the women over a cylinder gas cooker, a table-top electric hob or a paraffin stove.

After Nairobi, I return to my childhood home, Uboro, a rural village in Nyanza Province far from the nearest city, Kisumu. I love the freshness in the air. Over time, much of the surrounding area has been cleared for farming, but the land has been degraded. The soil is easily washed into the river ‘ugege’ from the hill where I collected firewood as a child.

My elderly mother serves food cooked using the traditional three stones and firewood or, when there is charcoal, on traditional charcoal stove called a jiko. The Jiko is used sparingly to save on the cost of charcoal but, in her old age, my mother is not strong enough to gather firewood for herself.  She uses some of the little money I send her to buy firewood from the market.

African evenings can be chilly so, as a child, I loved to sit round the fire with my siblings while my mother cooked a simple meal and shared her wisdom with us. The smoke from the kitchen brought tears to our red eyes which only stopped when the food was ready to be served!

Cooking food in a solar oven could reduce the need for fuel and so reduce the burden on women to gather wood or pay for expensive sources of fuel. It would also reduce health hazards for women labouring for so many hours over a fire and for their children who accompany them.

Solar cooking is an environmentally friendly technology that could contribute to the solution, provided that the technology is accepted by end-users and that the solar ovens are both appropriate and affordable. However, it is important to understand a community’s way of life and traditional practices before deciding on what’s good for them.

Currently there are many efforts to design an appropriate solar cooker; some are already being marketed or distributed. There seems to be a race to be the first to get the product to market regardless of whether it is culturally acceptable.

It is important to appreciate that African families come in different sizes, and that cooking pots will vary according to family size and the types of food being prepared. Like others, Africans prefer to cook inside the house. The fire warms the house for those who would use the kitchen later as their bedroom, and the smoke, it is believed, kills the insects that invade a muddy grass thatched kitchen. Those without fridges use the smoke to dry food so that it does not go bad. The intended user of a solar oven MUST be involved in deciding what would be culturally appropriate in their situation.

 Right now, there is much innovation in the humanitarian and development sector. In fact, innovation is a strategic priority of many aid organizations. Several UN agencies such as the WHO, UNICEF and UNHCR have their own innovation units. Domestic governments in developing countries are recognizing the need for innovation in the public and social sector to improve services. Individuals are also busy making their contribution, thanks to modern technology. But key to innovation is to ensure citizen participation in researching novel methods, especially from intended beneficiaries!

I commend the Oxford University students for engaging with someone with first-hand experience of the context and the people’s way of life, even if their current assignment is a paper exercise. It is my hope that when they complete their studies and get to apply their knowledge, they will remember to involve the intended customer or beneficiary!

Research into the medicine supply chain in developing countries

Cranfield University gave me the opportunity to study a subject close to my heart. I spent over one year researching in-country supply chain factors that affect medicine availability at service delivery points in developing countries. In this short video I share my motivation for the topic and my plans for future research.

I hope you enjoy the video and leave your comments on the subject. I am available to work on short-term research contracts through PSA Ltd.

The Politics of Humanity


Recently, I had the opportunity to hear John Holmes (UN Under-Secretary–General for Humanitarian Affairs and Emergency Relief Coordinator between 2007 and 2010) speak in Oxford on ‘The Politics of Humanity’,  an honest evaluation of the world of humanitarian relief aid based on his recent book of the same name.

John spoke of his experiences of missions to Sri Lanka, Darfur, and the DRC Congo and the challenge of being an emergency relief coordinator. ‘What was he supposed to be coordinating? The International humanitarian set-up is not a ‘system’ in any recognizable sense. Rather it is a collection of organizations and groups which have, over the years, been morally impelled to alleviate the world’s misery’. As the overall emergency relief coordinator, he had no authority to command the aid organization to do things in a certain way. His job was made more difficult by the diverse nature of humanitarian aid organizations with different mandates.

He saw crisis from both sides: the reality on the ground in some of the bleakest places on earth, as well as the strategic view from a comfortable diplomatic chair. He revealed the difficulty of being true to humanitarian principles, particularly in conflict settings where governments tried to use humanitarian aid for their own political aims. ‘Humanitarian relief must not be used for political or security purposes, still less withheld for such resources, or manipulated in other ways. Humanitarian aid is a moral imperative, not part of anyone’s stabilization strategy’.

In closing, he stated that of we must invest more in disaster risk reduction to have a reasonable chance of keeping pace with the growing need otherwise the world may face huge catastrophes without the means to tackle them effectively.

I recommend his book to anyone wanting to learn more about the challenges of applying humanitarian principles in a political world.

Heriot-Watt University Edinburgh

Occasionally, I'm invited to speak to an audience on humanitarian logistics which gives me the opportunity to meet new people and visit new places I might not otherwise see. An invitation from Kate Hughes to speak to MSc Logistics students at Heriot-Watt University Edinburgh was one such opportunity.

I was fascinated by the beauty of Edinburgh, this being my first time to visit Scotland, and what it had to offer: great hospitality, stunning scenery, and a rich cultural heritage.

Having a guest lecturer can give students the opportunity to hear from those with long-term experience in disaster response and humanitarian relief giving personal insight in to the unique challenges of this area of logistics and supply chain. I was able to share with the students my professional experience in humanitarian logistics in Africa, as a woman and as a 'local': the advantages and the challenges, and to share about my studies.

I was delighted to meet a diverse group of students who listened keenly and asked important and intelligent questions. I have always found the opportunity to exchange with students to be of mutual benefit where both parties gain from the ensuing discussions.
