Other advanced analytical techniques, such as link analysis, can be used by internal auditors and
fraud investigators to better understand relationships among employees, vendors, and
customers, to uncover money laundering or other fraud schemes. The analytic scenarios are
unlimited, providing vast opportunities to add value to the end consumer through various
reporting channels and options.

Consistent Processes

Defined and well-controlled processes are necessary for the continued success of a big data
program. Without defined and consistent processes, environments can quickly become unstable,
and the confidence in the underlying data can be lost. When analytic reports designed to provide
strategic insights use inaccurate or incomplete data, their value is immediately undermined. If risks
such as these are not addressed, big data programs can quickly lose funding and be eliminated.
Therefore, as people and technology are being deployed, careful attention should also be paid to
the underlying processes and related controls that support the big data program.
