Data Quality: the first metric that matters for PM success
Ram Guduru talks about the benefits of Performance
Management and points out the importance of data quality
Performance
management (PM) solutions, combined with associated best-practices and business
processes, are rapidly becoming recognized as the best vehicles for the most
strategic use of an organizations information. In fact, Hackett Group
research illustrates that companies with world-class enterprise performance
management generate 2.4 times three-year equity market returns, including stock
price increase and dividends, of typical companies in their industry.
Through disciplined PM practices, companies can align their
operational and financial information, internal processes, and strategic goals
to build competitive advantage, increase return on investment, and drive superior
business results. PM technology combines data from a multitude of sources and
transforms it into actionable performance information that provides a single,
consistent, accurate view of corporate processes and performance. This process
ensures that reliable performance information reaches the right people in the
right way at the right time. With PM, business users throughout the enterprise
can consistently make better decisions around three key performance-related
questions:
- How are we doing? Organizations can
measure and monitor performance with scorecards and dashboards that track
key metrics.
- Why?Reporting and analysis capabilities
let organizations uncover the reasons behind good and bad performance by exploring
the data, gaining context, understanding trends and spotting anomalies.
- What should we be doing?Through plans,
budgets, and forecasts, a business can set and share realistic and reliable
views of the future.
As the appetite for consistent, reliable performance information continues to
grow, accompanied by the demands of increasingly stringent compliance legislation,
many organizations are recognizing the indisputable importance of data quality.
If performance management solutions are to be effective, it is imperative they
be built on a foundation of high-quality data that delivers a single version
of operational and financial performance. This is a non-negotiable requirement
and it is the first metric that is fundamental to successful performance management
deployments.
Armed with the knowledge that PM based on quality data will result in greater
commercial opportunities, forward-looking organizations are addressing the issue
of data quality as an essential component of their performance management implementations.
They are seeking to ensure that they have the best possible quality data on
which to base critical business decisions.
The key dimensions of data quality
Given its critical importance, the logical question that arises is, What
exactly is data quality and how does one measure it? Good data quality
is defined in a number of different ways, but ultimately it is about the data
meeting the needs of the information consumer. To measure data quality we need
a well defined set of metrics that we can use to set targets for data quality
and measure conformance to those targets. Organizations quite often begin their
data quality process with three or four of the metrics or dimensions below and
then add dimensions from this list or define new ones, such as timeliness, to
track as their processes mature. Developed as a guide, the following six dimensions
can help business personnel achieve a fuller picture of data quality and better
understand how to optimize it within their enterprise. They also provide a common
language that enables business and IT professionals to work together to deliver
the highest levels of data quality.
- Completeness: Does the organization have
all of the relevant data? Are there empty or default values in fields? What
elements are missing or unusable and how will their absence affect the organizations
PM initiative.
- Conformity: This deals with the format of
raw data and content related issues such as incorrect format within the field.
For example a name prefix in the customer name field or noise around telephone
numbers. In addition, businesses must assess what data values are stored in
non-standard formats. For example, does a part number (which should contain
only digits) include spurious alphabetical characters?
- Consistency: What data values return conflicting
information? For instance, in a record, you might have a currency field for
the United States with the currency represented in Euros. Or a US address
might have a Canadian alpha-numeric postal code.
- Duplication: Are there records that are repeated
and skewing the data? There should always be a unique ID associated with each
record, but often when organizations look more closely at the raw content
of other fields, there is a high degree of probability of duplicates. For
example, they need to check if there are aliases that should be aggregated
(e.g. International Business Machines and IBM)?
- Integrity: What data is missing important
relationship linkages? Fuzzy matching can be used to identify records which
should be linked to each other.
- Accuracy: This concerns comparing data with
a reference source. For e.g. using a lookup table for an exact match to see
what data is incorrect or out of date. In this scenario, a purchase date cannot
come before a birth date.
A business-focused approach
To support these six dimensions and address the critical aspects of an organizations
data quality, companies should look for an open, platform neutral architecture
that addresses their need for solution standardization. Data quality deployments
should focus on the business users role in ensuring data quality. Data
across the full breadth of the enterprise must also be addressed to achieve
success.
Furthermore, data quality and performance management implementations should
operate in a virtuous cycle that combines people, processes and technology in
an iterative process of continuous quality improvement. This linkage ensures
that the appropriate members of the organizations business team take ownership
of their data and collaborate with IT to provide effective business rules for
transforming this data into consistent, actionable information across the organization,
ultimately enabling higher performance.
This type of an approach to data quality stretches beyond point solutions that
call for an exclusively IT approach to address data quality. These types of
approaches result in an incomplete resolution of data quality issues and do
not effectively address the dimensions of data quality discussed previously.
While IT is responsible for getting the raw data, they do not own
the data contents or are necessarily aware of its context. This is the role
of the business.
Business or IT: who owns data quality?
Traditionally, businesses seeking a consistent, complete view of information
focused only on the information management layer of the extract, transform,
and load (ETL) processes involved in converting data to actionable information.
Many still do.
As organizations PM data increasingly comes not just from a single data
warehouse but from a wide range of disparate sources, and as more organizations
combine transactional, financial, and operational data to drive business decisions,
the historical, IT-centric approach to data quality is no longer adequate.
Today, data quality excellence to support performance management deployments
mandates an approach that combines both business and IT. While IT focuses on
the data infrastructure needed to support performance management, business users
must focus on the business rules that determine what information is provided,
and that requires knowledge of business needs and an understanding of the language
and nuances that must be brought to the table when collaborating with IT. In
short, data quality in support of BI and performance management demands an integrated
effort by IT and the business.
Bringing PM capabilities to bear on the issue of data quality means that ongoing
data quality can be managed using data quality dashboards, scorecards and alerts
to continuously improve and monitor the quality of the data that underpins business
performance.
This approach lets business users monitor key data quality metrics (data quality
dimensions), just as they do other performance-related metrics. Consequently,
business users are engaged in the process of improving and owning the quality
of their information. This buy-in helps facilitate the on-going
process of data quality and enables the more rapid adoption of data quality
and performance management initiatives.
Better quality data for better performance
Because high quality data is central to the strategic business needs of todays
organizations, data quality has become a priority on the corporate agenda.
By combining data quality technology with their performance management technology
and initiatives, organizations can ensure the quality of the data on which their
performance depends is monitored and continually improved.
