Training Plan for course on free and open source software (FOSS) for small and medium enterprises. This European project initiative aims to help to promote the use of FOSS in business. The purpose of this course is to provide you with an overview of the most important FOSS concepts and solutions that are available today for you to consider and use in your own business. The course is broken down into 5 main units with sub-topics in each unit. Each individual unit contains a summary in advance of a series of lessons on the topic. After this, the learner can undertake review questions and find links to further sources of information. The lesson units can be taken in any order depending on your level of interest and/or prior knowledge. As the course is aimed at learners of different abilities and prior knowledge, we have provided a pre-course survey in order to assess your current knowledge. We encourage you to complete the pre-course survey to help determine your level of engagement.
