+# Assignment: Data Science Scenarios
 
+In this first assignment, we ask you to think about some real-life process or problem in different problem domains, and how you can improve it using the Data Science process. Think about the following:
+
+1. Which data can you collect?
+1. How would you collect it?
+1. How would you store the data? How large the data is likely to be?
+1. Which insights you might be able to get from this data? Which decisions we would be able to take based on the data?
+
+Try to think about 3 different problems/processes and describe each of the points above for each problem domain.
+
+Here are some of the problem domains and problems that can get you started thinking:
+
+1. How can you use data to improve education process for children in schools?
+1. How can you use data to control vaccination during the pandemic?
+1. How can you use data to make sure you are being productive at work?
 ## Instructions
 
+Fill in the following table (substitute suggested problem domains for your own ones if needed):
+
+| Problem | Which data to collect | How to store the data | Which insights/decisions we can make | 
+|---------|-----------------------|-----------------------|--------------------------------------|
+| Education | | | |
+|---------|-----------------------|-----------------------|--------------------------------------|
+| Vaccination | | | |
+|---------|-----------------------|-----------------------|--------------------------------------|
+| Productivity | | | |
+|---------|-----------------------|-----------------------|--------------------------------------|

 ## Rubric
 
 Exemplary | Adequate | Needs Improvement
 --- | --- | -- |
+One was able to identify reasonable data sources, ways of storing data and possible decisions/insights for all problem domains | Some of the aspects of the solution are not detailed, data storage is not discussed, at least 2 problem domains are described | Only parts of the data solution are described, only one problem domain is considered.
