It is a fact that many small and medium-sized familiar enterprises disappear every year for not overcoming the problems and difficulties that the business transfer involves. • In 1996, the European Observatory for the SME estimated that more than 5 million companies in Europe (about 30% of all European companies) should have to face their transfer in the next years. In Spain, the percentage of familiar companies that face an inheritance process rises to 65% of the companies. • The mortality rate of a familiar business compared with the other SMES boosts to double, often failing in the moment of having to pass the baton of its management: one out of two familiar businesses does not survive to the change of the second generation. • But in front of these weaknesses, the familiar SMES have long tradition and experience; and knowledge often accumulated through working experience. Validating and formalising this learning acquired usually by not formal or informal ways (practical knowledge and tacit competences) to allow its transmission to the next generations are key values for the business continuation. From all this, we can conclude that it is necessary to elaborate and make available for the familiar SMES some measures and tools to favour the business transfer and the knowledge management. The transmission of knowledge is an important question for the survival and development of these companies in the present changing context and to reach a learning culture. Regarding this, MAGISTER project, valorising a good European practice to transfer not formal training in the companies (TACITUS: I/03/B/F/NT/154072), is aimed at boosting information and knowledge interaction and exchange in the familiar SMES in the Metal Sector. Through the adaptation of TACITUS project results, MAGISTER developed and experienced a transnational intervention model (Guide) allowing the familiar Metal SMES to identify and valorise the knowledge and competences (including those acquired through not formal or informal learning) and to favour their transfer to future generations, basing on quality standards and on the best practices with gender perspective and addressed to the specific needs of the SMES.
