Based on a study on the future of the food service industry, volume I of this three-volume report contains a series of scenarios intended to make 10- to 15-year projections into the future of the food service industry and to serve as a basis for replanning the vocational-technical curricula in the food service area. The scenarios are "canonical variations" of the model that the authors call the "Standard World" (adapted from the Bureau of Labor Statistics Employment Model). These scenarios present descriptions of the food service industry as it is expected to be affected by different circumstances. Three scenarios are based on optimistic economic assumptions; another scenario focuses on general areas of public sector food service; two more explore pessimistic economic assumptions; still another describes the foods which will be eaten in the future; and the final scenario explores the restaurant service. A discussion of the curriculum planning needed to prepare for the projected growth and change in the food service industry concludes volume I. (BM)
