It helps to reduce context-switching during long data science workflows.
An integrated data stack boosts productivity
As I noted in my previous post, Python programmers willing to go “all in”, have Python tools to cover most of data science. Lest I be accused of oversimplification, a Python programmer still needs to commit to learning a non-trivial set of tools1. I suspect that once they invest the time to learn the Python data stack, they tend to stick with it unless they absolutely have to use something else. But being able to stick with the same programming language and environment is a definite productivity boost. It requires less “setup time” in order to explore data using different techniques (viz, stats, ML).
Multiple tools and languages can impede reproducibility and flow
On the other end of the spectrum are data scientists who mix and match tools, and use packages and frameworks from several languages. Depending on the task, data scientists can avail of tools that are scalable, performant, require less2 code, and contain a lot of features. On the other hand this approach requires a lot more context-switching, and extra effort is needed to annotate long workflows. Failure to document things properly makes it tough to reproduce3 analysis projects, and impedes knowledge transfer4 within a team of data scientists. Frequent context-switching also makes it more difficult to be in a state of flow, as one has to think about implementation/package details instead of exploring data. It can be harder to discover interesting stories with your data, if you’re constantly having to think about what you’re doing. (It’s still possible, you just have to concentrate a bit harder.)
Michael Flowers explains why applying data science to regulatory data is necessary to use city resources better.
A predictive data analytics team in the Mayor's Office of New York City has been quietly using data science to find patterns in regulatory data that can then be applied to law enforcement, public safety, public health and better allocation of taxpayer resources.
