The economic crisis in Europe, and all over the world, generates strong and large evolution of the national and local public policies. In order to implement those new policies, local authorities are depending more and more on the third sector organisations. But, they do not know deeply those organisations. For instance, they do not know their projects, their business models, their governing processes, etc. Also, the third sector organisations often have an incomplete view of the public authorities, focusing only on their funding role. Those views are related to the lack of time in local authorities and in third sector organisations but also to the actual trainings which do no stimulate mutual knowledge. One of the main objectives of SPOTS Project (Sustainable Projects for Organisations of the Third Sector) is to facilitate the mutual knowledge of those 2 categories of organisations using the tool of the training. The 4 partners of SPOTS project are: IFAID Aquitaine (France), the coordinator, professional training centre involved in International solidarity and community development for 30 years (learners of IFAID training will also participate in the project), BAIRROS (Portugal) non-profit organisation supporting the development of the third sector in Lisbon, Advantage Business Agency (United Kingdom), consultancy specialized in support to the Third sector, with a strong expertise on business management, AEC (Algeria) non-profit organisation that contributes to link public funders and enterprises creators in the Beajia Region. This partnership is based on mutual knowledge and previous mutual projects. . SPOTS will last 3years and follow an agreed and common methodology. A first stage will identify the existing representations of each of the 2 categories of actors and the existing ways of cooperation for building local policies in each country. Needs assessment documents and document of recommendations in each country will be produced, also completed by the experience of each partner. In a second stage, a training will be elaborated in order to better understand mutual aims and perspectives. This training will be implemented in each partners’ countries. After, it will be improved thanks to training evaluations. Pedagogic material will be created.. The methodology, chosen for SPOTS Project, is based on participation of SPOTS partners and of the different categories of actors, related to public policies implementation, in each country. At the end of each stage, a multiplier event will be organized in order to communicate and disseminate SPOTS results. At the end of the project a final wide dissemination event will take place in Portugal. SPOTS will facilitate a co-building approach of public policies and develop new knowledge and skills for the learners. Those learners will be able to adapt themselves better to the world constant evolution. These co-building public policies practises will respond to a double demand: a better use of public funds and more sustainable 3rd sector organisations who participate in the implementation of public policies. This sustainability will be reached by a better articulation between organisations project and activities and by long-term business models.
