Engineering is an essential action as it contributes to the development of the PLIE action programme. It fully participates in the achievement of its objectives by participating in identifying the needs of the PLIE participants, mobilising local actors, designing and developing projects and monitoring them. The PLIE will work on experimenting with complementary actions under ordinary law to strengthen the offer of career stages, to have a range of actions for the benefit of the participants and to encourage the removal of certain obstacles in access to employment. These are: * carry out diagnostics and studies to provide a shared and up-to-date vision of the audiences and actors involved in the offer of inclusion in the North, * create structures or tools, training activities, develop common working methods. * support the professionalisation of actors and structures carrying the path reference points. * mobilise various funding needed to carry out the projects This engineering operation helps to enshrine the PLIE in a dynamic of local development. The PLIE will also be able to support all the initiatives of the partners contributing to the achievement of the objectives.
