The survey was conducted by Teksouth Corporation, a provider of data management and analysis systems. More than 50 data warehousing professionals were surveyed. Of those responding to the survey, 62 percent said they factored in time and cost overruns while budgeting for the cost of implementing a BI/DW system. In addition, two-thirds 68 percent- said that actual overruns forced them to either scale back their efforts, or request additional funding to complete the project, with more than half reporting either moderate or major delays. The survey also reported that more than one-third of the respondents 36 percent- said that, despite advances, planning and implementing a data warehouse is still incredibly tough, saying it s a given that the project will take longer or cost more than anticipated. Two-thirds of those responding to the Teksouth survey said they have encountered unanticipated problems while designing and implementing their BI/DW system. 44 percent of them said those problems had caused delays. The survey also revealed that more data warehousing professionals consider Oracle to be their primary database, by an almost two-to-one margin, with Cognos as their primary business intelligence analysis tool. Teksouth is a Cognos Silver Technology Partner. Source: www.dmreview.coma>
