Nermertes Research said its latest "Collaboration Applications" report is based on five months of in-depth interviews with more than 120 IT executives at large companies (about $10 billion in annual revenue on average).
Nemertes said its interview results indicate that some IT executives will consider open source, but many do not think it is enterprise ready and also have concerns about support costs. IT executives surveyed said the ongoing maintenance of open-source applications would be higher than for commercial off-the-shelf products.
Others concerns raised by some of the IT execs include scalability, security, reliability and feature sets which they said outweighed potential capital cost savings on open source.
"There's a clash of cultures," Irwin Lazar, principal analyst & program director at Nemertes, told internetnews.com. "You have a lot of open source companies saying 'Here's the future of computing, here's the source code, anyone can do whatever they want.' It sounds great to the user, but from a large company perspective, there are real world compliance and security issues. In most cases they need a company or some entity backing the software before they will adopt it."
