Top Big Data Use Cases

Several logistics companies like FedEx, DTDC, DHL, etc make use of the data in order to improve the efficiency of their delivery logistics operations.

With the help of data analytics, several delivery logistics companies have found ways to devise the best shipping routes, suitable delivery time and the most ideal means of transport and in turn, have been successful in gaining cost efficiency.

5. Customer Interactions

One of the arenas which uses data analytics for customer interactions is insurance. Insurers can determine and rectify any issues with their services by carrying out customer surveys regularly after they have interacted with the claim handlers.

Using Big data analytics tutorials one can get clarity about which services of theirs are good and which ones are bad. By taking the customer demographics along with their feedback, insurers can improve the customer experience on the basis of the insights and behavior of the customer.

This type of analysis does this by keeping all the parameters into account and gives suggestions for how a future opportunity can be taken advantage of or how a future risk can be mitigated. It also illustrates each and every decision’s implications which in turn improves the decision-making.

The perspective analysis uses the concept of the next best offer analysis and the next best action in order to retain customers. Some features of perspective analysis include,

(a) Forward-looking analysis technique.
(b) Focused on providing optimal decisions for any kind of situation in the future.
(c) It offers simple rules for highly complex models.
(d) Based on differences and similarities, a discrete prediction of the components of a data set can be made.
(e) Decision rules and optimization for events in the future.

2. Diagnostic Analysis

While determining the cause of an event, the diagnostic analysis technique can be of great help to a data scientist. It is a very useful tool when research on usage trends and churn indicators are being carried out.
Analysis of customer health score and analysis of churn reason are a few diagnostic big data analytics examples.

A few features of this type of analysis are given below.

(a) Backward-looking technique.
(b) Focused on analyzing causal sequences and relationships.
(c) The relative ranking of variables or dimensions is based on the explanatory power that is inferred.
(d) The dependant or target variable is attributed to independent dimensions or variables.
(e) This includes Bayesian as well as frequentist inferential analysis.

Churn risk, next best offers, and renewal risk analysis are some predictive big data analytics examples. Here a few features of the same.

(a) Forward-looking technique.
(b) Mainly focused on giving out non-discrete predictions of relationships, states, and patterns in the future.
(c) It helps in describing the probability distribution of prediction result set along with likelihood.
(d) Its a form of model application.
