Getting into Analytics and Decision Science
Bala: Could you please let us know what inspired you to pursue a career in Data Science?
Piyanka: “When I ventured into tech about two decades ago, Data Science wasn’t a buzzword at all. In fact, there wasn’t a particular field called Data Science or Data Analytics. I’ve always been fascinated by Mathematics since my school days. I could prove theorems with ease and had a flair for problem solving.
I continued to nurture my love for math throughout my undergraduate days and then delved deeper into statistics in my grad school. As part of my thesis, I worked on using non-linear regression to model radioactive spills through inverse speciation. I then went ahead to pursue my second Masters in Computer Science, where my thesis was in the domain of AI.
Throughout my learning journey, I was never complacent with just knowing things, and was always driven towards analyzing what I could do with the acquired knowledge to solve problems and drive impact.
I started my career as a coder. After a while, I wasn’t quite comfortable just coding as I was impact-driven and highly motivated to solve business problems. I came across a job listing for the role of a Senior Analyst and I knew that was me! You could name that as the first ‘Data Science’ role if you may, albeit I had been using statistical methods and putting data to work long before that. I was the Senior Manager of Marketing Analytics at Adobe and then worked at PayPal where I also headed the Business Analytics division. And then I started building Aryng.
That’s my journey. Summing it all up; from math through a deep dive in statistics, to proven leadership experience in analytics and data-driven decision science.”
Building and Leading a Data-Driven Organization
Bala: You’ve been building Aryng and have been leading from the front. Could you please summarize the journey of Aryng – the growth, challenges and milestones?
Piyanka: “Any company’s journey is packed with challenges and interesting turning points. In the early days, the focal point of Aryng was Data Literacy.
In simple terms, data literacy is all about empowering people with the skills they need – to put data to work towards better decisions for themselves and their organization.
We started working with teams at Google, Epson, Box and other clients in the Silicon Valley. We set out to measure the impact that our training brought to the data culture of the organization, and weren’t quite satisfied. This motivated us to chart out a more involved methodology that would actually allow us to measure the impact that our training had on the data culture as well as on the top KPIs of the client organization. It involved the following.
- Identifying top projects and use cases.
- Acquiring the right data literacy skills
- Acquainting the clients with BADIR – our flagship strategy that can be transposed onto the functioning of any data-driven organization.
You can read more on BADIR strategy here. (It all starts with the Business Question!)
We then figured out through our experience that the successful working of any data-driven organization relied on 4 D’s – Data Maturity, Data Literacy, Data-driven Leadership, Data-driven decision making process. The development of data culture assessment and being able to positively impact the KPIs of the client organization are some of the key milestones in the journey. We’ve also been doing some cutting edge work for our clients developing machine learning and AI models as part of our Data Science consulting. That said, we are a growing organization bootstrapped by the founders. We would like to be found more easily on the web and continue to deliver our best and create impact at scale.”
Advances and Challenges in Data Science
Bala: As you’ve been in the Data Science industry for a long time, would you like to tell us about the trajectory that Data Science has taken over the years?
Piyanka: “In my opinion, it all starts with the business question! Let us consider a generic problem of requesting the sales records of a particular region for a specific period. A natural first step to take would be to get started with the data collection process. But, is that what you should be doing? No, the first step is to ask what business questions are associated with the specific data of potential interest. When you ask questions, you know what to look for. This again is what the BADIR advantage elucidates. Data collection comes after you’ve understood the Business question and have drafted an Analysis Plan.
Algorithms, models, and tools do not have any intrinsic value by themselves. Model when coupled with decisions and alignment with the key stakeholders requirement becomes useful and valuable.
Another key concern when harnessing the power of data is to validate whether the required infrastructure is available at disposal. It is also needed to verify maintainability and more importantly, answer the question – is a complex model on the available dataset needed to solve the business question at hand?”
Understanding and Harnessing the Power of Data
Bala: Understanding data and gaining actionable insights is the key to building impactful solutions – What would be your take on this dictum?
Piyanka: “Absolutely! Analytics to me is all about the synergy of Data Science and Decision Science. We all have intuitions. All that we need to do is to tap the power of intuitions to formulate hypotheses and build models that extend our intuitions, thereby driving decisions.”
Bala: What would be your views on the power of data, regardless of the industry? How do you believe that the power of data can be best harnessed?
Piyanka: “The very first forecasting model was built in 1930. It was a credit scoring model built by Fischer and Durand. However, using correlation amongst features predates even that. When I was doing my Masters, I had coded my model from scratch in C. I would start running a program, let it run overnight, and come back the next morning with the hope of finding useful results.
Today, the landscape has changed significantly. There’s easier access to compute resources such as GPUs and computations can be outsourced to the cloud. There has been a momentous change in the way we look at computing.
There is also the added advantage of leveraging the power of pre-trained models. For most problems, it’s often not needed to code from scratch. There’s a wealth of repositories that can give us pretty much any model that we want. However, this democratization of Data Science can often bring in a few gaps in understanding and building effective models. Leveraging pre-trained models is good, but a good Data Scientist should still be able to understand feature engineering, treatment of outliers and dealing with class imbalance and other typical problems.
The future of data science is in the hands-on of those who are well equipped to bridge the gap between business and extremely evolved data science infrastructure. That remains the biggest gap in data science. ”
Advice to Data Science Enthusiasts
Bala: What would be your advice to all the data enthusiasts?
Piyanka: “It’s extremely important to identify where your passion lies. Ask yourself the question: Do you want to take up Data Science just because it’s another buzzword? Or is using data to solve business questions and drive decision-making your sweet spot? Once you figure out the answer to this question, if you think you’d like to pursue a career in Data Science, be sure to chart out a definitive path.
My advice would be to identify your dream roles and companies, read through the job descriptions, the acumen and expertise that each role demands. There’s a plethora of roles in the industry – data scientist, data analyst and data engineer to name a few. Once the aspirants identify the role that excites them the most, it’s time to start working backwards by gaining the requisite skills, and bridging the gap, one step at a time. In my book, Acing Your Analytics Career Transition, I talk about these steps, deconstructing the different stages.”
Skills and Traits of a Data Scientist
Bala: What are the essential and desirable skills and traits that you look for in prospective candidates?
Piyanka: “Well, there are a few sets of skills, grouped together depending on the roles that a particular candidate is applying to. However, I would like to zoom out of the different roles and the allied skills and rather focus on certain essential skills that are role-agnostic.
- To be a good Data Scientist, systematic problem solving is sacrosanct. A good candidate should definitely demonstrate the ability to deconstruct a problem statement into chunks and delineate a systematic approach to solve the given problem.
- In the industry, it’s all about understanding and solving a business problem to drive decisions that actually create impact. Therefore, being adept at problem solving is an essential skill, regardless of the role that the prospective candidate is interviewing for.
- A data scientist should always be inquisitive enough and curious to ask questions. If data scientists are complacent that they know it all, it’s often possible that they are indeed missing out on seeking answers to some of the most important questions that matter.
- Another most important trait that I look for is enthusiasm. If you do not stay enthusiastic throughout the journey, it’s often difficult to maintain the momentum that’s needed to drive impact.”
Bala: If you were to recommend learning paths or resources for those looking to break into Data Science, what would they be?
Piyanka: “I would say that there’s no one learning path as such that can potentially work wonders for all roles alike. Not everyone needs to know everything. They only need the skills that their level demands. Someone who’s looking to lead content marketing strategy doesn’t need to be able to build regression models. At our academy at Aryng, we offer progressive paths that are role specific.
As I said earlier, it’s all about figuring out the end goal – that role in your target company that excites you the most, and then work backwards, picking up and diligently working on the skills that matter.”
Bala: Could you please suggest a few other leaders whose interviews you would like to see as part of the ‘Data Science Leaders’ interview series?
Piyanka: Nick Offney, Matthew Denesuk, Sunpreet Singh, Amit Dingare
