Q1. How did data analytics capture your interest and propel your career in this dynamic field?

A: Hari’s journey into data analytics began about 25 years ago, rooted in his initial career in advertising and brand management. He was intrigued by the subjective nature of understanding customers in marketing. Faced with varied opinions about consumer profiles, he sought a more factual, empirical approach to understanding them, which led him to explore data analytics.

In addition to this, Hari’s role in managing a department in a large organization further fueled his interest. He realized the significant role of metrics and data in decision-making and saw an opportunity to enhance business strategies through data analytics. This shift from relying on personal knowledge and gut feeling to using data-driven insights became a key focus in his career.

Today, Hari’s work heavily involves marketing analytics, particularly in customer analytics and journey mapping. His experiences highlight the transformation from intuition-based to data-informed decisions in business. He emphasizes the value of data analytics in providing objective, reliable insights for strategic decision-making in various organizational contexts.

Q2. What does data analytics mean in simple terms?

A: Hari explains that data analytics doesn’t have one standard definition. It’s sometimes called big data analytics, business analytics, or data sciences. Despite its complex nature, in essence, data analytics is the combination of technology, science, and art to derive meaningful insights and outcomes for specific problems.

The complexity in data analytics arises from the different methods people use to apply technology, science, and art. At its core, it involves analyzing data to find the best technological, scientific, and artistic approaches for gaining insights or solutions to various challenges or opportunities.

A relatable example is online shopping, like on Amazon; when you search for a product, a lot of analytics work in the background. This process involves examining your browsing history and other data to provide you with the most relevant product recommendations. This recommendation engine exemplifies data analytics in action: processing and analyzing data to enhance customer experience. The ultimate goal of data analytics in this context is to ensure a top-notch customer experience by presenting the most appropriate recommendations.

Q3. What are the different roles and functions in the field of data analytics?

A: Hari highlights the ever-growing range of roles in data analytics, broadly categorizing them into several key skill sets. The first is data management, which includes roles such as data engineers and data analysts. This area, referred to as ‘upstream’, focuses on managing, housing, and processing data.

The second crucial skill set is analytics, where roles like data scientists and business analysts come into play. These professionals turn data into meaningful insights, a process crucial for understanding and utilizing data effectively.

Another important aspect is the presentation of data, involving roles like reporting analysts and visualization experts. These professionals, seen as ‘downstream’ in the analytics spectrum, make the insights accessible and understandable.

In addition to these, domain expertise is vital. This expertise varies based on the industry and specific problems being addressed, adding relevance and specific context to the data analysis.

Finally, translators play a crucial role across the entire spectrum. They simplify complex data and insights into forms that are easily understandable by people both within and outside the organization.

Hari emphasizes that these are the five primary roles in data analytics, though there could be additional nuances depending on the organization or specific use cases. These roles collectively cover the end-to-end process of data handling, analysis, and interpretation, making them essential in any organization focusing on data analytics.

Q4. How do you determine the right problem to solve with data analytics?


a: Hari explains that in data analytics, there are three key objectives to identify the right problem to solve: ‘run better’, ‘run different’, and ‘transformation’.

The ‘run better’ stage is about improving existing processes. It involves evaluating current operations to enhance efficiency and effectiveness, focusing on top and bottom line improvements. This is the foundational level where the goal is to outdo current methods.

The ‘run different’ stage goes beyond mere efficiency. It’s about finding novel ways to address problems or seize opportunities, thus changing the approach to tackling issues.

The ‘transformation’ stage is a complete shift in methodology. Hari uses the example of shifting from a traditional retail model, where consumers come to pick up items, to a delivery model. This kind of transformation requires a completely different set of data and analytics compared to just enhancing existing processes.

In each stage, problems are broken down into use cases. These cases are assessed for the availability of relevant data, the capability to analyze it, the computing power required for insights, and the execution of these insights. A well-defined, executed use case that demonstrates impact can then be scaled into a broader business strategy.

Use cases are further categorized based on impact and effort, like ‘high impact low effort’ or ‘low impact low effort’, aiding in prioritization. This methodology is well-established in the data analytics field, guiding organizations from specific use cases to comprehensive, overarching functions.


Q5. How do you assess if an AI or data analytics system’s recommendations are effective?

  1. Hari outlines several methods for evaluating the effectiveness of a data analytics or AI system. The primary method is the ‘champion challenger’ approach, where the current system is compared against a new or alternative system. This comparison, using test-and-control samples, helps determine which model is more effective.

Another method is ‘out of time validation’, where you apply the developed algorithms to a different time period to assess their performance. This checks if the model is robust and reliable across different contexts.

Hari emphasizes the role of use cases in this evaluation process. In data analytics, everything starts with a use case, which defines the problem or opportunity being addressed. He highlights that you’re not just looking at efficiency but also at effectiveness, meaning you explore different ways to tackle the problem or opportunity, and that becomes your use case. Depending on the stage of your journey, you define your use cases accordingly, whether it’s about doing things better, differently, or transforming the business.

The kind of data and analytics required for transformation can differ significantly from other objectives. For instance, the data needed for a retail transformation, moving from in-store to delivery models, is different from data used in enhancing in-store customer experiences.

Additionally, use cases can be positioned differently based on impact and effort, such as ‘high impact low effort’ or ‘low impact low effort’. This categorization aids in prioritizing them. Once a use case is well-defined and executed with a significant impact, it can evolve into a broader business strategy.

These methodologies — champion challenger, out of time validation, and strategic use case evaluation — together provide a comprehensive framework to assess the efficacy of AI and data analytics systems in addressing specific business challenges.

Q6. What skills and certifications are required for a career in data science or data analysis?

A: Hari outlines several key competency areas and skills essential for aspiring data scientists or data analysts:

Technology: A robust technology background is crucial. This includes skills in computer science, coding, data management, and data manipulation.

Techniques: This area covers the analytical aspect of the field, including predictive analytics, data science, advanced analytics, and model building. Typically, a background in statistics or economics is beneficial for this.

Business Intelligence and Reporting: This involves converting insights into formats that aid decision-making. It requires a blend of technical and analytical skills and the ability to present data compellingly.

Domain Expertise: Understanding specific industries, such as banking or supply chain management, is vital. This expertise ensures the relevancy and applicability of data analytics within a particular domain.

General Management Skills: Project management, effective communication, and stakeholder management are crucial. These skills help translate technical details for non-technical stakeholders and align projects with business objectives. Hari emphasizes the importance of this skill set, comparing it to client servicing in an agency.

Hari also notes that while there are specific tools and technologies to learn over time, the choice of specialization or broad skill acquisition depends on individual preferences. Some may choose to delve deeply into data science or AI engineering, while others might opt for a more versatile skill set across multiple areas.

In addition to these competencies, Hari mentions the evolving nature of the field, where professionals often strive to master more than one competency. This multidisciplinary approach, while challenging, can be beneficial in the dynamic data analytics and AI landscape. He emphasizes that understanding these competency areas and continually adapting to new tools and methodologies is key in building a successful career in data science or data analysis
