Owing to the diffusion of computers--personal as well as highly sophisticated models--and of modern data bank systems and more accessible programming methods that no longer require hiring professional programmers to develop a variety of applications, administrators are increasingly using this new technology as a basis for making more realistic decisions. Good information systems are of great importance in the management of local health systems; however, in order for them to be truly useful, data collection must be homogeneous so that the data may be subsequently consolidated and compared. In this connection the authors present a model consisting of four stages: strategic planning; analysis of needs; allocation of resources; and selection of alternatives for consideration by project teams and suppliers of equipment and programs.
