What is the use of Big Data?
Big data can help you track range of business activities, from customer experience to analytics. some of them are given below.
- Product development – Almost all companies use big data to predict customer demand or services and modeling the link between those attributes and the commercial success of the offerings.
- Predictive maintenance – Factors that can predict mechanical failures may be deeply buried in structured data, such as the year, make, and model of equipment, as well as in unstructured data that covers millions of log entries, sensor data, error messages, and engine temperature. By analyzing these indications of implicit issues before the problems takes place, companies can deploy maintenance more cost effectively and maximize elements and equipment uptime.
- Customer experience – The race for making customers experience good is on. A crystal clear view of customer experience is more possible now than ever before. Big data helps you to collect data from social media, web visits, call logs, and other sources to improvise the interaction experience and maximize the value delivered. Start delivering personalized offers, minimize customer churn, and manage issues proactively.
- Fraud and compliance – When it comes to security, it’s not just a hacker you’re up against but the entire expert teams. Security landscapes and compliance requirements are continuously emerging. Big data helps you seeks patterns in data that indicate fraud and aggregate large volumes of information to make regulatory reporting much faster.
- Machine learning – Machine learning is a widely spreaded hot topic for now. And data specifically big data is one of the reasons why we are now able to teach machines except of program them. The availability of big data to train machine learning models makes that possible.
Operational efficiency may not being in news, but it’s an area in which big data is having the most impact. With big data, you can analyze and assess production, customer feedback and returns, and other factors to reduce outages and anticipate future demands. Big data can also be used to improve decision-making in line with current market demand.
- Drive innovation – Big data can help you innovate by studying interdependencies among humans, institutions, entities, and process and then determining new ways to use those insights. Use data insights to improve decisions about financial and planning considerations. Examine trends and what customers want to deliver new products and services. Implement dynamic pricing. There are endless possibilities.
