Gareth Henham: better quality often not
achieved
|
IT SERVICES GROUP: Xansa
Interviewee: Gareth Henham, head of the BI and data management
practice.
Q1. Data quality.
A: Often the quality of the data input is assumed
to be of a satisfactory level mainly due to the fact that
it supports the operational systems and no-one ever measures
it. Better quality is often not achieved because of a lack
of focus in three key areas – information strategy, information
architecture and data management.
A business must first devise an overall strategy for exploitation
of the information available to it. This should address corporate
reporting needs as well as set expectations. Working with
key business managers is the vital ingredient for success.
The output is all about understanding what information is
needed to manage the business and how this will be made available
to the end user via the information architecture.
It is not sufficient to measure the quality of the data at
a particular time and build the solution based on that analysis.
Data management has to be treated as an ongoing process that
needs to be embedded in the organisation – rather than a one-off
activity – so that the quality of the data improves over the
long term.
