Cognizant’s Data Quality Ring
Cognizant offers Data Quality services using its
Data Quality 'Ring' methodology. The 'Ring'
methodology helps the business establish a logical
and sustainable process to monitor Data Quality
and apply quality controls. The 'Ring'
methodology, when used with best-in-class tools
such as Informatica Data Explorer (IDE) and
Informatica Data Quality (IDQ), will help set up a
high quality information environment.
Some of the best practices incorporated as a part
of the Ring methodology are:
— A cross-domain approach and technique for
improving Data Quality (not restricted to
customer data)
— Establishing a Data Quality oriented
'Governance Committee' to oversee the Data
Quality program
— Identifying and establishing ongoing metrics to
monitor and communicate the state of data
quality to key stakeholders across the
organization
— Attention to data coming in from outside
organization boundaries, e.g., POS, EDI inputs,
etc.
The Quality Ring to Safeguard your Enterprise Data
• Cognizant Solution Overview
Solution Overview 2016|
Perspectives on Data Quality in the organization
are still mostly based on assumptions and notions
rather than on facts and measures. Very few
businesses have matured to a stage where metrics
are used to constantly assess and communicate
the state of Data Quality in the organization. It has
been observed that poor Data Quality has costed
organizations 10-30 percent of their revenue.
With time, businesses have realized that Data
Quality issues are no minor irritants for IT but
glaring problems that impact strategic initiatives
and prevent achievement of goals and efficiency.
The quality of enterprise data is now tightly linked
with the success of other key initiatives including
Governance, Risk and Compliance Management,
Master Data Management and Customer Data
Integration. The need for error-free data has
never been stronger or clearer.

Build Quality Rules
Repository (QRR)
This step is used to unearth all data related issues.
It is not only “bad” data that always constitute
data issue. Non-compliance with the business
rules of the organization can also constitute a
quality challenge. Hence, Cognizant begins the
assessment by building a Quality Rules
Repository (QRR) to use as a benchmark for
assessing conformity and consistency of data.
Finally, the quality of data is assessed using QRR
and presented using the Informatica Data Quality
(IDQ) tool.
Step 2: Building Business Case
investments for the data cleansing and iterative
quality control initiative. Here, Cognizant helps set
up the required governance committee policies to
guide the Data Quality initiative on an ongoing
basis.
Step 3: Data Cleansing
In Step 3, Cognizant undertakes the necessary
steps to rectify the errors highlighted during the
assessment phase. Once the current data errors
have been corrected the processes to re-assess
data on an ongoing basis are set.
Sustenance:
The rules and metrics needed to sustain an error-
free information environment were established in
Step 1. These can now be used to develop the
reports or dashboards required for ongoing
monitoring. If any quality issues are identified in
the future, the Ring methodology can be used
again to rectify them.
