Data Engineering Use Cases in the Retail Industry

Data Engineering Use Cases in Retail Industry

To understand the value of data engineering in the retail industry, let’s take a look at the top five use cases, which are currently being implemented by leading companies:

Customer Behavior Analysis:

Data-driven customer insights are important to resolve retail challenges, such as personalizing campaigns to improve revenue, optimizing customer conversion rates, lowering acquisition costs, and avoiding customer churn. These days, users interact with a brand through mobile devices, stores, eCommerce sites, social media, and more. This increases the complexity of the data type and the variety of retailers that have to categorize and analyze it. Data engineering helps unlock insights from customer behavior data (structured and unstructured), enabling retailers to combine, integrate, and analyze data to facilitate customer acquisition and loyalty.

Personalizing In-Store Experience:

Before big data was launched, merchandising was considered an art form. Retailers did not have any means to measure the impact of their merchandising decisions. Later, a new trend was introduced when big data and online sales grew. Shoppers would physically look for the products in-store and order them online later. This gave rise to tracking technology which offers new means to analyze store behavior and measure merchandising impact. Data engineering allows retailers to drive meaningful data to optimize their merchandising strategies, personalize the in-store experience, and offer discounts to encourage users to complete purchases. The end goal is to improve sales rates across all channels.

Improving Conversion Rates:

A 360° view of customers’ buying habits and prospects can help increase acquisition and lower costs. Retailers can then effectively target promotional campaigns. Earlier, customer data was limited to demographic data collection means. But today, user interaction is more due to the influence of social media and other channels. Data engineering allows retailers to correlate customer purchase histories with their behavior on social media sites. It often reveals unexpected insights that retailers can use to target their ads by placing them on multiple channels like Facebook pages, Insta Ads, TV shows, etc. They can test and measure the impact of their promotional strategies on conversion rates. Data engineering also helps identify user interests and generate personalized promotions.

Customer Journey Analytics:

Today, customers are more connected than ever because of smartphones, eCommerce, and social media. They can access information and decide what, where, and when to buy and at what price. Customers can make better buying decisions and purchase wherever and whenever they want. Due to this, marketers have to continuously analyze, understand, and connect with customers. It requires a data-driven approach to understand the customer’s journey across channels. Data engineering helps analyze structured and unstructured data, regardless of the type. This reveals patterns and insights about what’s happening in the customer journey, who are high-value customers, and the best approach to approach them.

Supply Chain and Operational Analytics:

Retailers face intense pressure to optimize their performance, service quality, budgets, and asset utilization. This will eventually help them gain a competitive edge and improve business performance. The key is using data engineering platforms to improve operational efficiency and unlock insights locked in machine, log, and supply chain data. It combines structure data from ERP, CRM, geolocation, public data, and mainframe and syncs them with unstructured data.

How Do AI And Big Data Deliver Real-time Consumer Insights In Retail?
