QUESTION 2 OF 25

Your customer wants you to explain the benefits of the Big Data model you developed, how do you communicate the insights they can use for their business?

Everywhere you look in corporate America; you will find Big Data. It's fast becoming one of the most important facets of a business's operation. Big Data is used for data analytics and data management. If you want to know if your company is profitable or losing money, big data analytics can provide that. If you want to see what product sold best in a specific region of the country or world, big data analytics can provide that information. It's like having a dashboard with multiple screens in one that shows the performance of your company, people, processes, etc. Everyone talks about this concept, but very few can articulate the benefits of big data and how it can help a business. This is especially true for data consultants who are new to big data. Depending on the level of experience that you have, one of the most important areas that you should focus your response on is highlighting the insights that the customer is going to realize when they implement a big data solution.

The interviewer is interested in hearing about how you present benefits to the customer in a way that connects with the customer's pain and adds value to the company. Effective communication is key here. They might ask for a hypothetical scenario where you clearly presented a case for big data and it's benefits. It would help to mention that they would be able to calculate metrics for data gathered from multiple sources like social media, customer profile data, company website, etc.

"My expertise has been in Data Analysis, so Big Data to me was a pretty flat and easy learning curve. When you're working with large volumes of data, you need to make sure that the data is scrubbed (clean) so that the information can be interpreted by the organization so they can use that data to make better business decisions. I was able to do this by using data warehouse applications that broke down the data in smaller manageable groups that had relevant information about each customer or prospect. Based on my knowledge, there are a lot of benefits that a company can get out of big data. Here's a short list that I have compiled based on my experience:

1. Ability to acquire, extract, modify, analyze, and blend the data with various business intelligence tools in order to get the information you need to run your business.
2.You can evaluate risk by a portfolio of products or services.
3.Be able to customize customer experiences.
4. You can identify important information or performance data to improve decision making.
5.Real-time forecasting and monitoring across company-wide locations, divisions, and business units.
6.You can monitor sales and marketing campaigns, and track customer purchasing habits."
