How do successful data scientists think about data?
To design, develop, and deploy the right solutions for business, the way you think and conceptualize solutions also influences a lot.
“someone with a deeper understanding and intuition for what they are doing is a true data science whiz, and will likely have a successful career in this field.”
-Lee Barnes, Head of Paytronix Systems
There are several models representing thinking patterns and as a data scientist, following them as applicable would help you to model data and communicate with your decision-makers effectively. Two of them are briefed here as a reference.
1. Design thinking mindset
Design thinking is nothing but a structured approach taken to solve problems. It comprises qualitative activities supporting the generation of human-centered design solutions. Though the activities vary from project to project, the core theme revolves around — empathize, define, ideate, prototype, and test.
📌 Empathize
Conduct ethnographic interviews to gain a deep understanding of the user journey and the pain points. Open-ended questions throw light on conclusions that we would never have arrived at through deductive reasoning alone.
📌 Define
The systematic acquisition of data will help you to form and test hypotheses against quantitative evidence. It serves as the starting point for innovation while addressing users’ needs in a unique way.
📌 Ideate
Here, there is every chance for process automation. You can design and train a behavioral model that can measure how and to what extent the hypothesized solutions can address the pain point and predict its influence on user behavior.
📌Prototype
Involve visual designers, interaction designers, and strategists to sketch out product features, build user journeys, develop business models, and product roadmaps. Of course, this might undergo extensive iterations to address the pain points uncovered during research, maximize product uptake and bring higher returns or revenue to the organization.
📌 Test
Testing uncovers the mistakes or opportunities you did not realize. There could be a pain point or user behavior that was not identified earlier but became apparent when users started to interact. This helps to change or refine the product features, if and as needed.
2. Agent-based thinking
It is a simulation modeling technique and conceptually deep that offers solutions to real-world social or business problems. The agent-based modeling mindset refers to describing a system from its constituent unit’s perspective. It is similar to microscopic modeling.
The thinking is here is more individual-centric like the physical/mental state of an individual, the individual’s interaction with the environment and other individuals. This individual-centric thinking is applied to physical assets, individual consumers making purchase decisions, organizations making markets efficient, and even the government.
From a business context, it can be applied for traffic, customer flow management, stock market, operational risk, organizational design, innovation of products, and adoption dynamics.
The model illustrated here describes a multi-scale agent-based model to study the impact of cohorting strategies on Covid-19 dynamics in metropolitan cities. The studies provide a quantitative trade-off on cohort size and its impact on disease dynamics. It shows that cohorts help to reduce disease transmission without significantly impacting ridership or social activity.
In addition, there are other models such as behavioral thinking, systems thinking, and forest thinking. To summarize, data scientists are deep thinkers with an intense intellectual curiosity to discover new things. Above all this, taking the right approach is also essential.
Let’s see how…
How does a successful data scientist take the right decision?
According to data scientists, data science can be used in different ways depending on the industry, business, and its goals.
Jonathan Nolis, a data science leader says that the ability to make good PowerPoint slides is important than using the most sophisticated deep learning models. The concept here is that the skills we know today will change tomorrow. In the open-source ecosystem of tools and commercial tools, there is ever-increasing automation, and therefore, the skills have a relatively short timescale.
Further Jonathan Nolis divides data science into three components
- Business intelligence: Taking the company’s data in front of the right people
- Decision science: Using the data to make a decision in the company
- Machine learning: Putting data science models into production continuously
To be a successful data scientist, one should focus on critical thinking, quantitative and domain-specific skills apart from techniques.
