Outsourcing has brought about changes in the activities carried out by the Public Administration, which has started to focus intensely on its core activities, handing over the middle activities to private companies through contracts. The management of administrative contracts needs to be in line with the principles of legality, impersonality, morality, publicity and efficiency. This work deals with the management of outsourcing contracts in public administration. The supervision of contracts in public administration in the age of outsourcing, although fundamental to the smooth running of projects and programmes, has not been given the same care and support as the planning of bidding processes. The general objective of this study is to systematically discuss the challenges faced by managers and inspectors of outsourced service contracts. The research took a basic, exploratory and descriptive approach, and was qualitative in nature. Finally, it was concluded that the biggest challenges facing the category today are the lack of qualifications and poor training.
