How is Data Science Transforming Various Industries in India?

Data science application across industries have yielded transformative results. For instance, data science in the banking industry reduces fraud, detects suspicious behavior, strengthens customer privacy, and improves customers’ overall banking experiences. Here, we have listed how data science application can transform various industries.

1. Healthcare

Digital technologies support healthcare providers in functions like prescription management, healthcare records, and a patient’s medical history. This generates enormous amounts of data, which can be used to gain insights and make data-backed intelligent decisions.

Here are some ways data science applications have yielded transformative results in healthcare.

1.1. Patient Diagnosis

After the COVID-19 pandemic, the number of online doctor consultations and medical deliveries has seen a significant increase. Moreover, healthcare professionals can now monitor patients’ heart rates, blood pressure, and blood sugar levels with IoT wearable devices like smartwatches. Furthermore, these wearables contain sensors and advanced processing abilities that can deliver accurate patient data for medical analysis.

In his keynote address at ETCIO Spectrum 2021, Dr. Ram Sewak Sharma, National Health Authority (NHA), CEO, expressed that the Indian government is focused on leveraging technologies like data science, the Internet of Things (IoT), and analytics to boost healthcare service delivery.

1.2. Improving the Efficiency of Medical Instruments Manufacturing

Data analytics will play a significant role in India’s healthcare transformation. With modern technologies like artificial intelligence, machine learning, and deep learning, healthcare providers can improve the efficiency of medical instruments by taking large amounts of data and identifying errors.

1.3. Drug Development

Developing a new medicine is a long and expensive process that requires months of research and testing. However, with data science, researchers can evaluate millions of test cases faster, helping them develop effective and safe medicines in less time.

2. Finance

Data science is a rapidly evolving field with ever-advancing methodologies and tools. Financial institutions can use it to identify lucrative opportunities and financial risks. Here are some ways data science applications have yielded transformative results for the finance sector.

2.1. Fraud or Risk Detection

Finance companies employ data science tools and methodologies to analyze data and quickly detect fraudulent or risky activity, safeguarding them from financial losses.

2.2. Predictive Analysis

Finance companies employ advanced algorithms to analyze previous and current data to predict customer behavior, market trends, and financial risks. These predictions allow companies to make data-backed financial decisions.

3. Manufacturing

Data science enables manufacturing companies to optimize their operations and increase efficiency by providing insights into production and supply chain management. Here’s how data science is transforming the manufacturing industry.

3.1. Optimize Supply Chain Management

With data science and analytics tools, manufacturers can track and monitor the entire supply chain in real time. This helps reduce the risk of supply chain disruptions. Additionally, it allows manufacturers to quickly identify and resolve any issues that may arise, such as a shortage of raw materials, delay in the delivery of goods, or a lack of products in the inventory.

3.2. Predictive Maintenance

Data science also excels at predictive maintenance by employing machine learning algorithms. M Manufacturers can forecast potential machine failures, enabling timely maintenance to prevent breakdowns.

3.3. Process Optimization

Manufacturers can leverage data science algorithms to evaluate large amounts of data and find ways to improve manufacturing processes. This helps businesses earn more profits while spending less on production.

3.4. Price Optimization

To determine the cost of a product, various factors like raw materials, labor costs, overhead expenses, and distribution costs are considered. Data science helps manufacturers determine the cost of products by analyzing all aspects of production and sales. This way, manufacturers can determine the price of a product quickly.
