This chapter discusses the external and agencies. Broadly they are of two kinds: governmental and non-governmental. The former may be subdivided into executive or departmental agencies and others. The non-departmental agencies enjoying the stamp of government are principally two: the Comptroller and Auditor General (CAG) and Parliamentary Committees. The CAG has access to all records and probably reasonable knowledge of what records and information exist on any issue under query. Among the most purposeful in a good evaluation system today are the non-governmental agencies such as Price Commissions, Pay Boards, and Monopoly Commissions. The chapter brings out certain specific institutional developments in progress within the enterprises themselves. Departmental evaluations are fundamentally under the impact of the government's or the minister's political interests; they tend to be over-defensive of the performance, partly for reasons of departmental involvement in enterprise decision making and management.
