It can be done. You can implement a Learning Management System and not spend millions of dollars. You are not forced to turn to NetG, WebCT, or other large systems that perhaps your company can't quite afford. You can just use an open source LMS. The open source LMS that I have heard the most about - all pleasant, mind you - is Moodle.
What is Open Source?
First off, you should understand that open source means that the application is free. It also means that various programmers are constantly developing the application, improving it. If, in your use of the product, you improve the product, you are expected to share that with the entire product user base.
Surprisingly to many, open source applications tend to have better than average support. Perhaps this is because the programmers have a lot of heart and soul invested in their creations. Open source apps also tend to have a large user community that communicates via forums or other means, providing an endless offering of ideas, support, and suggestions.
That said, go ahead and take a look at Moodle. You may appreciate what it has to offer.
eLearning with No Budget
A recent "report" from the Australian Flexible Learning Framework takes a look at creating eLearning using open source software and readily available hardware. It explores everything from MP3 Players to cell phones as additional tools in eLearning. It covers several open source products, including Moodle, as well as open source assessment development software, such as Hot Potato. While the report/white paper is written in a very conversational style, complete with happy faces and cute graphics, it also exposes some valuable information.
You don't have to have a huge budget to create effective eLearning. You just have to know where to look.
