Solving for ambiguity: what the data literate can learn from the design process

1. solve for ambiguity what the data literate can learn from the design process @deanmalmgren @DsAtweet 2014 february norc

2. data scientists thrive with ambiguity solve for x Ax=b optimize f(x) optimize “our proﬁtability” project evolution x=5+2 optimize Ax=b subject to f(x) > 0 @deanmalmgren | bit.ly/design-data

3. origins of ambiguity many feasible approaches @deanmalmgren | bit.ly/design-data

4. origins of ambiguity unclear problems identify the best locations to plant new trees @deanmalmgren | bit.ly/design-data

5. origins of ambiguity unclear problems identify the best locations to plant new trees aesthetically pleasing? maximize growth? increase foliage? offset CO2 emissions? how many? what kinds of trees? move old trees? replace old trees? @deanmalmgren | bit.ly/design-data

6. “design process” is used everywhere anticipate failure generate hypotheses evaluate feedback 1-4 week iterations build prototype @deanmalmgren | bit.ly/design-data

7. “design process” is used everywhere anticipate failure human-centered design lean startup agile programming evaluate feedback generate hypotheses personas, scenarios, use cases business/product requirements story/user cards 1-4 week iterations build prototype surveys, interviews, focus groups split testing, A/B testing QA; requirements churn build device prototypes minimum viable product write code @deanmalmgren | bit.ly/design-data

8. design and data science challenges in practice problem lost in translation generate hypotheses takes a long time to collect data, analyze, and build visualization evaluate feedback 1-4 week iterations build prototype proof is in the pudding @deanmalmgren | bit.ly/design-data

14. informal conversation to stated goals mostly bad ideas, but a few good ones Lorem Ipsum: a narrative about blankets. Charlie Brown Date: 31 Jan 2012 ! Author: Lorem Ipsum is a dummy text used when typesetting or marking up documents. It has a long history starting from the 1500s and is still used in digital millennium for typesetting electronic documents, page designs, etc. ! In itself, the original text of Lorem Ipsum might have been taken from an ancient Latin book that was written about 50 BC. Nevertheless, Lorem Ipsum’s words have been changed so they don’t read as a proper text. ! Naturally, page designs that are made for text documents must contain some text rather than placeholder dots or something else. However, should they contain proper English words and sentences almost every reader will deliberately try to interpret it eventually, missing the design itself. ! However, a placeholder text must have a natural distribution of letters and punctuation or otherwise the markup will look strange and unnatural. That’s what Lorem Ipsum helps to achieve. ! Peppermint Patty for her support on studying Lorem Ipsum as well as the inﬁnite wisdom of Linus van Pelt and his I would like to thank willingness to use his blanket in my experiments. @deanmalmgren | bit.ly/design-data
