"Vendors talk about the technology, but not how to actually do it by providing methodology."

Barnett said consolidation in the industry means there are fewer vendors, pointing out that IBM Corp. and Microsoft Corp. account for 35 percent of all software sold in the world.

"That's a third of the market. Most of the software sold today is provided by the top 10 companies," he added.

Barnett also took a swipe at vendors who over-use the word "innovation".

"I find myself signing NDAs (non-disclosure agreements) in my discussions with vendors only to hear that their great new strategy is about innovation; everyone seems to be competing on this," he said.
