Finding the value

In most cases with Big Data projects you have to ingest 6-10x more data than has any immediate value just to start and glean value.

This creates a large expense and a lot of issues for entry, which has derailed  a number of big data projects. So be prepared going in that unless you really know your data you will need to ingest and explore to find the value. When you…

Big Data can help in mapping and understanding customer behaviors, and in developing one-to-one marketing programs or innovative services. However, Big Data is too often presented as a technological capability subsequently requiring armies of data scientists to mine and analyse data.
