Principles of management: an analysis of managerial functions

language used. "Words in a contract are not self enforcing" (p. 74). This spirit is affected by the relationship between the parties, the area and extent of mutual understanding, and the will to work things out. Professor Troxell finds "Of declining influence, too, are the misgivings which used to find so frequent expression in the phrase 'technological unemployment'" (p. 79). This seems an optimistic appraisal in light of the recent statements by many persons concerning the effects of automation. In this area, as in so many other sectors of the economy, there are no simple, pat answers. "Experience with plans or formulas for evoking good teamwork reveals that no single pattern predominates." Programs must be tailored to the needs of each industry or plant. Industry characteristics, as well as the personality traits of the leaders involved, will play an important role in determining the proper plan. On the whole, the author is hopeful that the gains from teamwork and cooperation can be rich. There can be little quarrel with this hope, but the road is a long one, and many pitfalls beset the unwary traveller. This volume provides a useful guide.
