The second barrier to business intelligence is the high total cost of ownership (TCO), said the analyst group.
Large enterprises will need three times as many business intelligence personnel in 2008 as they did in 2004, Gartner predicted in a report of the findings of a survey presented at its Business Intelligence Summit in Chicago last week.
"Lack of skills and TCO are related because projects that require a lot of trial and error are more costly," said Gartner vice-president Howard Dresner.
"High TCO is a barrier particularly in Asia and for those who deploy business intelligence for the first time. In Japan, nearly half of the respondents said that difficulty in learning to use business intelligence hampers its adoption."
Gartner surveyed 920 companies across different industries and countries, including the UK, to gauge enterprises' attitudes towards business intelligence.
