CCT333H5S Prof. Mike Jones March 15, 2010 Scenarios and Requirements
 * SCENARIO # 1 (JUAN CAMILO DIEZ) **

Water shortage in many African Countries is a huge problem, water is vital for survival and life. When a family living in a village or cite far away from water anybody will have to trek for miles just to get to a source of water; whether it be a child, woman, or older male. once they bring back the one or two containers of water, they have to store them in their tiny huts or outside where they are prone to the elements. the weak containers can also rip easily and leak; and when its something as valuable as water/life, no chances should ever be taken. Families should be making less trips and be worrying less about the safety of their water.

These less fortune families and members of the word society, need to be able to store water safely close to their home. instead of making various trips per week, they should be able to make one FAMILY trip, to gather as much as possible, and then save it all in one big container. A heavy duty yet light, portable and easy to repair container. since the elements in Africa contain wild animals, the families need to be sure that they also wont be able to get to their precious water. in case of any type of wind storm, their water containers should not roll away, or be brutally destroyed by nature.


 * SCENARIO #2 (MATT ZGOMBA) **

An African woman and her two young children are living at home, while the father/husband works and is the sole income provider. This mother has many obligations to fill while her husband is at work and her children are at school for part of the day. In the morning, it is necessary to provide some food for her family, and the mother uses whatever water she had left over from yesterday’s water ration. Using the water from yesterday may suffice some times in the morning, but fetching more water is almost always the first thing the mother must do with her children.

Once the water is acquired, every takes a drink, because this is usually the coldest the water will be all day while stored in their home. Another problem that this family encounters regularly is the issue of their water storage containers breaking and requiring replacement. The family struggles to find a high-quality container that can withstand the many situations in which they use the containers. The family tries to keep a portion of their water cool for drinking so that they can feel refreshed at any point in the day. Using water for multiple purposes without worrying about having enough for the next morning is something that the family would love to be able to do.


 * SCENARIO #3 (RASHA SHEGEM) **

Water is the lifeblood for daily survival, from drinking and washing to growing food. But for many people in Africa, that lifeblood is a pitiful and dirty filter. Millions of women need to spend several hours a day collecting water with putting aside their jobs of taking care of the children and cooking and jobs a housewife should do. “One-third of the African population has no drinking water and almost half of the African people have health problems due to the lack of clean drinking water. “

In the morning parents are heading to work and have consumed all the water before going there, so no more stored water is available. Children come back from school, they could be sitting at home all alone while both parents are working. Those children are supposed to focus on studying, but however, they also need to drink water or add water to the food. If water wasn’t present at home those children need to go get water in which on the way the water containers could break, then children could be injured and instead of spending time on studying and focusing they are losing their time on getting water in order to drink and stay healthy.


 * SCENARIO #4 (HAYA ABUATA) **

There are many important things in life that is not correct in our world. For example; inequality, poverty, suffering, abuse, disease, and many others. Each has an upsetting shocking effect on people’s lives. And clean water is one of the main factors behind the major difficult issues facing the world. Water scarcity throughout the world is very important and it is very important issue since many African and Indian villages do not have access to clean water.

Poor people living in rural areas (Africa) lack clean water and suffer from, malnutrition, diseases such as AIDS, malaria, and pneumonia. Many children die from a combination of diseases – infected water and malnutrition. Water borne diseases kill on average one child every 3 seconds. African families suffer from the water scarcity and the access to infected water. Parents start to worry about their kids, and in order to provide their kids with healthy food they need clean water, huge amounts of water are needed in order to grow food. Access to clean Water is very important for relieving hunger in developing countries, and makes life much easier and healthier for children and parents.


 * SCENARIO #5 (JESSIE LIANG user:iehzinha)

It is now half past noon and the sun beams high. As we approach the end of March, the temperature in Mumbai, India is unbearably hot and dry at 39oC. Still, under these scorching conditions, masses dislocate around the city for lunch. Streets are crowded with people, cars, bicycles, and cows. In Dharavi, [|the second largest slum in all of Asia] , two families from from Uttar Pradesh arrive to their new "home".

The two men (fathers and thus, providers) ponder as to how they will build their house and attempt to congregate a new shelter that will fit all nine of them. In the maze that is the Dharavi slum, they figure that the only area with enough space available is kilometers away from any water supply. At the same time, the Mahim Creek is simply a source of diseases. The children are extremely tired from walking for hours and the mothers wish they just had some kind of shade so they could cool themselves to alleviate the heat from the saris that wrap around their entire bodies.

If only these and millions of numerous other families had access to a design that provided them with safe drinking water. This new device not only would store the potable water, but should be able to keep it safe and retrievable. Furthermore, it would need to be durable, resistant, and inexpensive. This device could benefit the families even further with long-lasting water filters, so to ensure an always clean water. An even better characteristic that would be interesting to insert in the design is to make this water storage device easily transported and movable. This way, families like the ones from Uttar Pradesh, can migrate to other areas when necessary, while still maintaining their pristine water source. **

 **What's a scenario** •A narrative that is accessible and useful to explain problems to stakeholders •A narrative that outlines complexity to designers in context •A narrative that is shaped both by designers and users - and increasingly shaped by users •Allows for understanding of many effects at many levels •Allows you to set the tone of redesign and sell it effectively to bosses, users, etc. •Envelops external factors/constrains •Sells the problem – makes your solution the obvious one, but **scenarios are not about your solution. **

•Anecdotes, observation, interview transcripts can directly yield information for scenarios •Should be told as close to user’s direct experience as possible - in their own words expressing their own issues •Left just at this level - just a collection of interesting stories, no attempt at creating common themes
 * Scenario elements: **
 * <span style="font-family: Georgia,serif;">1. user stories: **<span style="font-family: Georgia,serif;">

•Identification of common themes and problems •Builds conceptual models •Used for generating ideas for design alternatives, specifying requirements •One level of abstraction from user stories - but does not yet address how technologies resolve issues
 * <span style="font-family: Georgia,serif;">2. Conceptual scenarios: **<span style="font-family: Georgia,serif;">

•Defines requirements from conceptual scenarios more concretely •Operates on physical/prototypical models •Starts involving technologies and interaction patterns at a general level •May be many concrete scenarios from one conceptual scenario
 * <span style="font-family: Georgia,serif;">3. Concrete scenarios: **<span style="font-family: Georgia,serif;">

•From user stories and conceptual scenarios, build a list of what the technology should (and should not) be able to do •Functional (e..g., task oriented - what it does) or non-functional (e.g., aesthetic, legal, cultural, ease of use issues)
 * <span style="font-family: Georgia,serif;">Requirements: **<span style="font-family: Georgia,serif;">

•Must have (without this, it’s useless) •Should have (would be a clear value-added requirement but will work without it) •Could have (might be nice but not essential) •Want but Won’t have (can wait until future iterations) •Prioritization is important – you can’t often do it all, and it’s often a bad idea even if you could.
