In the old paradigm , consumers are served by human agent for example in the context of insurance industry. Policy holders are served by agent but that has been changed. Consumers are more and more interacting with organizations via digital channels such as mobile apps, facebook page, youtube campaign, newsletter, chatbot etc.

In that paradigm shift, consumers are expecting the digital channels must be “smart” meaning the channels must have all the information about the consumers that have been shared and stored with the enterprise on the system of records.

Data movement into the lake

In the past year, I have had worked with a customer (refer as ‘The Customer’) in the insurance industry. They have various data sources — both structured and unstructured — residing in disparate systems e.g. insurance policy management system, CRM, etc.

The Customer need to bring together those data sources to have a customer 360 view so that business users can have the fully integrated and comprehensive information about the customers to conduct various analytics workloads.
