2025-09-05

In the current digitized business landscape, leveraging big data for decision making is no longer a choice. it is a determinant of survival. From global giants like Netflix and Amazon to Small and Medium Enterprises (SMEs), the application of big data analytics is driving breakthroughs in operational efficiency and profitability.
This article provides a detailed guide on deploying business data analytics from foundational to advanced levels accompanied by international case studies and a specific checklist for action.
Why Enterprises Cannot Ignore Big Data and Data Analytics
The Power of Data in the Digital Economy
According to the McKinsey Global Institute, organizations applying big data analytics can increase profit margins by an average of 5-6% compared to industry peers. Instead of relying on intuition or experience, modern leaders utilize big data to make business decisions based on concrete evidence.
Big data enables businesses to accurately grasp customer behavior by analyzing data from various touchpoints. This allows for the systematic optimization of the customer journey and the improvement of user experience.
Adoption Trends in the Vietnamese Market
In Vietnam, the rate of enterprises adopting big data analytics is growing by 25% annually. Leading sectors, including banking, retail, and logistics, have begun shifting from traditional reporting to predictive analytics. However, the most significant challenge remains the shortage of specialized personnel and suitable technology infrastructure to deploy effective business data analytics solutions.
Three Levels of Data Analytics: From “Hindsight” to “Actionable Insight”
Descriptive Analytics – Understanding What Happened
Descriptive analytics forms the foundation of all analytical activities, focusing on describing and summarizing historical data. This level helps businesses answer the question, “What happened?” through dashboards, reports, and KPI metrics.
A prime example is Netflix, which uses descriptive analytics to track watch time, completion rates, and user interactions. This data creates the basis for evaluating content performance and adjusting production strategies. (Descriptive analytics is the description and synthesis of historical data )

Predictive Analytics – Forecasting Future Trends
Predictive analytics utilizes machine learning and statistical models to forecast future outcomes based on historical data. This level answers the question, “What is likely to happen?“.
Amazon serves as a classic case study with its recommendation engine, where 35% of revenue is accurately forecasted to come from product suggestions. Algorithms analyze shopping behavior to offer recommendations tailored to each individual customer. (Predictive analytics can forecast a portion of future results )

Prescriptive Analytics – Delivering Optimal Actions
Prescriptive analytics is the highest level; it not only forecasts but also recommends specific actions to achieve desired outcomes. This is the moment big data becomes a tool for strategic business decision-making.
Google Ads uses prescriptive analytics to automatically adjust bid prices, targeting, and creative content based on real-time performance data, helping to optimize Return on Investment (ROI) for advertisers. (Proposing specific actions is the highest level of analytics )

Case Studies: From Data to Revenue
Levi’s and the Fashion Trend Forecasting Revolution
Levi’s deployed an AI system on the Google Cloud platform to analyze data from social media, search trends, and sales data. As a result, the brand accurately predicted the return of the baggy jeans trend, leading to a 15% sales increase in the implementation quarter. The key lesson here is that combining multiple data sources (internal + external) helps businesses react quickly to market changes and create a sustainable competitive advantage.
McDonald’s and Intelligent Supply Chain Optimization
McDonald’s applies big data analytics to forecast food demand based on weather data, local events, and historical sales. The AI system automatically adjusts inventory levels, reducing food waste by 20% and increasing customer satisfaction by 12%. This case study proves that prescriptive analytics not only optimizes costs but also improves customer experience by ensuring products are always available and fresh.
Spotify and Personalization at Global Scale
Spotify uses big data to make business decisions regarding content curation, with algorithms analyzing over 70 million songs and the preferences of 400 million users. The “Discover Weekly” feature generates 40% more interaction and a 24% higher customer retention rate. Spotify’s success demonstrates that applying business data analytics at scale can create unique products and completely personalized experiences.
Comprehensive Benefits of Big Data Analytics
Improving Customer Experience
Big data allows businesses to deeply understand the customer journey and optimize every touchpoint. Analyzing sentiment data from social media and customer feedback helps improve service quality and product development.
Optimizing Operations and Reducing Costs
Prescriptive analytics helps automate decision-making processes, from warehouse management to resource allocation. This not only reduces human error but also accelerates reaction speed to market changes.
Forecasting and Effective Risk Management
Forecasting models help businesses predict potential risks, from market fluctuations to operational incidents. Early warning systems based on big data can reduce the impact of unwanted incidents by 30-50%.
Driving Product and Service Innovation
Data-driven insights open up innovation opportunities that traditional market research cannot detect. Analyzing unmet needs from customer behavior data serves as inspiration for product development.
Challenges and Solutions
Data Fragmentation and Quality Issues
Many businesses struggle with data scattered across multiple systems, leading to inconsistent insights. Data quality issues such as duplicate records and missing values also affect the reliability of analysis.
Lack of Governance and Data Culture
The absence of clear data governance policies and resistance to change from stakeholders are major obstacles in deploying enterprise big data analytics.
System and Personnel Solutions
Building a unified data platform with appropriate Extract-Transform-Load (ETL) processes is the first step. Simultaneously, investing in training and recruiting data talent ensures the sustainable success of data initiatives. Deploying change management programs to foster a data culture encourages decision-makers to use big data insights rather than relying on intuition.
