The first dimension is Public Management of the public sector of a country. It is normal for a sovereign state to manage resources of the country both human and natural resources to be used in the formulated public policy. This is to be executed with two major objectives: to resolve problems plaguing the country and to lay down the ground work for development of the society. In this regard, the central government would have to come to power through a legitimate channel. This part is the acquisition of power through the accepted rule of the game such as coming from an election. The other part is performance which is evaluated in the capacity of the government in power to come up with good achievements, known as performance. With poor public management, good results would not come forth and that would appear as “bad or poor performance.” which naturally would erode the political legitimacy of the government, coming to power through the right channel notwithstanding. And this would testify to the significance of public management. The criteria for performance have been devised such as what is known as KPI or Key performance Index. But the most quoted principle is what is known as Good Governance including in essence, legitimacy, transparency, accountability, participation, efficiency and effectiveness. It is to be pointed out here is that there is a close linkage between public management and political legitimacy.
