7:09 - 14:10 Learn who are the SME

  • What are their goal, their methods and their limits
  • Not designed for rapid growth, they provide a service for a particular group, it changes the kind of analysis you can do for them
  • They work a lot with Excel.
  • The problem with the Drew Conway Data Science Venn diagram. Too much focus on coding and machine learning, forgetting the domain expertise, which is a key element for data science.
  • Small business work in different businesses models
  • What is the data of SME. Spreadsheets, CRM, CMS, social media, emails, web analytics & SEO.

14:10 - 41:59 Limits to be aware of

  • Severely limited in money, time, personnel.
  • As a consultant adapt to SME to work with them. Simple quick & cheap. Answering to Yes or No questions.
  • What you need to do. Use common tools, be fluid in Excel. Use minimum sufficient analysis. Clarity & applicability, focus in what the organization can control.
  • What analysis you should know for them. Sums, counts, & percentages. Tables and pivot tables. Subgroup and filters in Excel.
  • Black boxes are not allowed. Human-in-the-loop analysis and decision making.
  • Data visualization needs to be really really simple. Use bar charts, maybe scatterplots, and line charts. Keep it as simple as possible. Users don’t particularly think like you do. Don’t include distractions.
  • Example of modern dance. Only a poem can translate a poem. Nothing for annotating and visualizing dance. Its an open problem work now. You can solve that problem.
  • Once you know how they work then you can connect with them, some examples of nonprofits like DataKind.org, Data Science for Social Good, Data world tour, or DIY.
  • Few suggestions to organize your own event: Ask for clear questions to answer. Prepare analysis templates. If possible, prepare data. Follow up. Adopt an organization, they all need the benefits of data science. What you get is: good practice, good networking, possible charitable donation.

41:59 - 45:42 Enable SME

  • Teach them, handing off, document thoroughly, explain decisions; plan for common tools, and for tools that doesn’t cost money; save in generic formats; save in accesible locations. Support self sufficiency, stay in contact, create materials.
