Found on BBC website a study, which questioned 1125 IT professional in Europe, revealing that more than 50% of IT projects are not delivered on time.

 

The study conducted by by HP and the Economist Intelligence Unit says the the 3 most commons causes for delay are :

• Outsourcing (it reminds me something)
• Changing priorities half way through (certainly not always an IT responsibility)
• Poor coordination between managers (sic!)

Other interesting points found on the article are that : 

• 51% of European IT's say there would be not risk to their job. This percentage slips to 33% in Asia and 22% in Americas.

• 57% of participants to the study said that less than 50% of the IT initiatives in their firms had a positive outcome. In 2006 this figure was 54%

In Europe Sweden comes first when it is about delivering IT project on time with 44% then follow

• Switzerland 24%

• Czech Republic 20%

• Germany 19%

• Denmark 16%

• UK 11%

• Finland 8%
