Datawarehouses are becoming more ambitious but not necessarily more successful according to a survey commissioned by the Evaluation Centre.
As part of a yearly survey of trends into datawarehousing and business intelligence, the survey found that companies are developing more ambitious datawarehouse implementations but are not necessarily seeing immediate benefits.
Even though 55% of respondents initially implemented datawarehousing as a single project, currently only one in five expect to do so now and just 3% in future. In contrast, three times more indicate they plan to introduce enterprise-wide datawarehouses, which will support a much wider range of departments and business processes.
Nearly 90% aim to improve management information flows by doing so, and three-quarters of the sample say they have achieved this. Half also report improvements in data quality, but in other respects results have proved patchy.
Only around one third or a quarter of respondents have achieved the benefits they sought in areas such as increased customer awareness (36%), increased sales (32%), cost cutting (28%) and identifying new products or trends (26%).
Cost cutting was a particular disappointment, with 28% saying they did not do as well as expected. Part of the problem seems to be the dramatic increases in data volumes many companies have recorded in recent years. More than a third estimate data volumes have gone up by 10% to 50%. However, 5% of the sample reported a 100% increase in amounts of data and 10% say there has been a 200% rise.
Despite the lack of progress in achieving some key benefits, just under half of the sample agrees that the implementation of datawarehousing has resulted in significant changes to their business. Two-thirds believe such applications are now business critical, and in recognition of this 57% of companies polled have a business continuity plan specifically for their datawarehouse application.
