The three-year Staff Needs Plan, as now provided for in Article 6 TUPI, is a tool aimed at 'identifying the needs of public administration'. It presupposes a mapping of administrative functions and requires consistency with the Performance Plan, as currently provided for in positive law. The three-year Staff Needs Plan must not, however, constitute an obstacle to good performance of public administration. Such good performance requires annual updating and compliance with the principles set by the Court of auditors. That Court has the duty to review so that its implementation is not arbitrary and does not harm the interests of the community.
