It implies an agreement between the University and a group of firms operating near the University locations. The main objective of this project is to develop business consultancy in a group of 15 firms established in the south of Madrid, next to the University Campus. The project has been implemented by researchers from the Business Administration Area in the Rey Juan Carlos University in Madrid, Spain. There have been fifteen participant firms. 6 teams of researchers formed by 2, 3, or 4 different members have developed the work. A group of diagnosis and propositions of improvement have been realised in the mentioned group of firms. Different methodologies of strategic and organisational analysis have been used.
