In most countries, OpenOffice.org attempts to penetrate markets that are already occupied by similar proprietary products. A strategy for promoting adoption must look at all the barriers that need to be overcome to ensure a level playing field that will allow the advantages of OpenOffice.org to be valued. The strategy must ensure that the right product is available (good complete localization of OpenOffice.org with help, adaptation, spell-checker). For the education system, it must revise official school curricula to ensure that they do not name specific products, and study which textbooks (according to local curricula) need to be developed to be able to replace others that teach using proprietary software. Similarly, it is important to have free course materials that service companies can use to easily put OpenOffice.org training as one of their products. While independent procurement of software tends to be strongly affected by marketing, to the advantage of proprietary software companies who have large marketing budgets, when ICT policy is made by countries (National ICT policy) or education systems (ICT in Education policies or plans), decisions have an opportunity to be more rational, with clear measurement of cost-effectiveness, and in some cases end up supporting the use of FOSS. To support this work, it is required to develop documents that show the comparative advantages of OpenOffice.org
