We live in an automated, data-driven world. Not long ago, analytics used to be the job of the analytics team only, which was the source of precious insights and business intelligence.
Nowadays, data is at the core of virtually every role in an organization, and everyone is responsible for generating his or her own insights. When it comes to career development, big data has become a bit like the proverbial bear: you either “eat” it by learning to tame and put it to work for you, or it eats you.
Looking around the professional world, the divide between these two groups is more obvious every day.
The first group (Group One) is made up of the most successful professionals out there, who can use the data available to them in order to build tailored solutions to the problems in their professional space. The best are also charismatic storytellers who can clearly communicate to prospects and stakeholders the value that their solution provides, and thus build a following that will work to make them even more successful in the future.
The second group (Group Two), and most numerous one, is made up of available task completers. While the first group enjoys high pay, engaging work and flexible schedules, the second group is forced to make a living by stringing together gigs of boring, mind-numbing work on an unpredictable schedule for abysmal pay. While the professionals in the first group have abundant opportunities available to them and enjoy high influence and prestige through their work, the folks in the second group have low-influence roles and face an increasingly competitive landscape of shrinking opportunities due to automation and outsourcing.
Many things could be said about this division, but most are outside of the scope of this article. It bears noting, however, that it is possible (though not easy) for one to shape oneself into a Group One professional, as the students at Edlitera show us every day. The point of this article is to lay out how, after acquiring the skills of a Group One profession, one can showcase these skills in a portfolio, in order to firmly establish oneself as an expert in ones chosen profession. Since most of Edlitera's students pursue Data Science as their chosen profession, this two-part article will go over how to build a data science portfolio.
A portfolio is simply a collection of projects. A project is a coherent piece of analysis, prediction and recommendations that focuses on answering a specific and well-defined question.
The primary goal of a portfolio is to showcase your skills and your ability to deliver a solid and coherent answer to the questions that prompted your analysis. Notice my use of the word “answer”, and not “result”. Many analysts and technical professionals tend to focus too much on technical details when talking about their work, which makes their answer to the original question very difficult to follow and understand by lay people. (More on that later, though.)
Before starting a new data science project, I strongly recommend giving this (free) book by DJ Patil a read:
In addition to the advice in this book, take some time to consider each of the following points:

This is why Data Science salaries are so high.
Learning to code? You're in good company! Here is why some Hollywood celebrities have been learning it too.
In this article, we continue our brief exploration of the command line and we learn some basic but very useful commands.
