30. Big Data Challenges
Data Scientists spend too much time ‘data wrangling’
“Data scientists, according to interviews and expert
estimates, spend from 50 percent to 80 percent of their
time mired in this more mundane labor of collecting and
preparing unruly digital data, before it can be explored for
useful nuggets.”
NY Times – August 17th, 2014
31. Big Data Challenges
Building a data science platform is very difficult
Infrastructure
•Choosing big data technologies and setting up a cluster can easily take 9
months or more
Data Pipeline
•Building a high performing big data schema requires specialized skills
•Extracting, transforming, and loading of data (data wrangling) is an
enormous time sink and a poor use of data scientists time
Analysis and Workflow
•Figuring out how you can ask questions of the data and how to visualize the
results takes time that data scientists should be using to generate actionable
insights from their studies
