We shall attempt an overall review of the material presented in the preceding chapters, introducing the comparative angle to the extent possible. At the outset it may be noted that total uniformity in presentation has not been their aim. An obvious reason for differences in coverage is that the enterprises belong to different countries and to different sectors and have evolved themselves in the public sector in different contexts of national strategies of development. While some of these will come out in this chapter, our focus is on aspects intrinsic to public enterprise organisation and on the differences in practical approach to the problems of apparent commonality.
