Task Differentiations. Occasional Paper No. 2.

The paper described the Input, Process, Product, and Impact (IPPI) model in preparation for a 1972 Management Information System for Occupational Education (MISOE) planning conference. The IPPI model is designed (1) to provide a structure for integrated State and local decision-making within occupational education and for decision-related descriptive information which accounts for reality by decision types within the model, and (2) to provide a framework for analysis of relationships between inputs and process with product and impact. The system also permits decision-makers to simulate the interactive effects of the total system over time. The model describes the totality of occupational education; links to the larger world occur with input and impact. The paper establishes some differentiations, distinctions, and definitions, and thereby provides a structure for project development which not only stipulates developmental tasks, but ties consultants and staff to development in a functional way. Eight tasks are described in the paper, related to space differentiations, variable selection, instrumentation, the sample, the information system, analysis types, simulation, and other information needs. The final section of the paper suggests an integrated procedure for task development, including a schedule for the planning conference. (Author/AJ)
