- Reduce dependency on closed source vendors. Stop being dragged through constant product upgrades that you are forced to do to stay on a supported version of the product. Aren't you tired of telling your customers to wait because you have to spend a month or two upgrading to version 7.01G of Product X and following it up with an incremental hot fix?
- Your annual budget does not keep up with increases in software maintenance costs and increased costs of employee health care. Your budget remains flat, you bought five new tools last year with new annual costs in the range of 18-20% of the original purchase price for "gold support", and your employees' health care costs shot up 25% again. What gives?
- More access to tools. You can get your hands a variety of development and testing tools, project and portfolio management tools, network monitoring, security, content management, etc. without having to ask the boss man for a few hundred thousand green backs.
- Try before you buy. Are you getting ready to invest in SOA, BPM, or ECM? Why not do a prototype with out spending huge sums of money? First of all, it allows you to get familiar with the tools so you can be educated when you go through the vendor evaluation process. Second of all, you might find that the tool can do the job and you don't need to lock yourself in to another vendor.
- Great support and a 24/7 online community that responds quickly. Despite the myths that you can't get support for open source software, the leading communities provide support far superior to most closed source vendors. Most communities have a great knowledgebase or wiki for self service support. You can also post a question and one of the hundreds of community members throughout the world will most likely respond in minutes. Make sure you chose software with strong community backing.
- Access to source code and the ability to customize if you desire. You can see the code, change the code, and even submit your enhancements and/or fixes back to the community to be peer reviewed and possibly added to the next build. No longer do you need to wait for a vendor roadmap that doesn't have the feature you need until their Excalibur release in the Fall of 2009.
- Great negotiating power when dealing with closed source vendors. Tired of vendors pushing you around because you don't have options? I wonder if companies like Microsoft would be more willing to be flexible with their pricing if you have 20 desktops running Ubuntu as an alternative desktop pilot initiative.
- Feature set is not bloated and is driven by collaboration amongst the community. Tired of products that consume huge amounts of memory and CPU power for the 2000 eye candy features that you will never use? With open source software, most features are driven by community demand. Closed vendors have to create one more feature then their competitors to get the edge in the marketplace.
- More secure then most closed source vendors. This topic is highly debated, but studies like this one from Trend Micro show that open source software is typically more secure.
- Bug fixes are implemented faster then closed source vendors. Actually, many bugs are fixed by the community before they are even reported by the users.
Oh, and #11.....it's Free!
