payments problems out into foreign reserves and financial stringency produced a domestic credit squeeze. Thus, the need for an efficient socialised trading system became more pronounced just when S.T.C. was beginning to show its major weaknesses; its abilities to operate under constrained foreign and domestic finan- cial conditions and fill the gaps created by emmigrating traders became less as they were needed more. By the middle of 1972 it was recognised by Parliament and Government that S.T.C. as it was then constituted had proved a failure and that major recon- struction was necessary. In a study of management and management agreements, the main question to arise is why S.T.C. failed, especially in light of the fact that other parastatals, formed at the same time (namely, the financial intermediaries) were nearly unqualified successes. The easiest answer would be to claim that the latter had access to more qualified personnel at all levels (many of whom had been working in the system for years) and that their nationalisation sim- ply entailed taking over existing organisational structures, while S.T.C. required nearly all new manpower and a new organisation to accomplish what had not been attempted before. While there is a certain amount of merit in such an explanation, it does not an- swer the question of how it was that S.T.C. did not succeed after it had been provided by McKinsey & Co., with an organisational structure, a set of detailed management systems and assistance in recruiting experienced manpower from overseas, as well as receiving nearly unlimited financial support at home. This chapter suggests that there were two immediate causes for the collapse of S.T.C. first, McKinsey & Co. provided S.T.C. with an organisational structure and, a set of management systems that were unsuitable, even for the tasks as perceived by the con- sultants; and second, a variety of policy problems occurred which were either overlooked or dealt with incorrectly by S.T.C. management and Government bodies responsible for policy related to S.T.C. With this discussion as a background, S.T.C.’s impact upon the Tanzanian economy will be sketched. It will then be possible to address the most basic issue relating to the S.T.C. failure, viz: the Corporation was designed to support the structure of the commercial sector in existence in 1970 and had no mechanism for changing its organisation and systems as the struc- ture of the Tanzanian economy moved away from serving the 7
