Historically, major consideration given to product management has focused on research and development or the introductory
stage of the product life cycle. The authors present an empirical study delineating the variables to be considered in the
product elimination process. More specifically, the elimination process is evaluated under a situation of poor product performance
despite a generally viable market. The basic objectives of the study were: to determine the significant variables in the product
elimination process of the Small Appliance Industry; to determine the relative importance of the variables; to examine the
interaction among variables. The data obtained through personal structured questionnaire interviews were analyzed and provided
a ranking of twenty-six variables relevant to the elimination process. Moreover, the Johnson's Hierarchical Clustering Schemes
was applied to determine the interaction among variables. The results indicate that profitability and financial variables
are most significant in the elimination decision-process. Second, the primary clusters of importance are concerned with market
share, market growth rate, consumer awareness, and competitive action. 相似文献

After making a solicitation, a lot can be gained by listening to a donor's questions. Do not simply answer the question. Consider why they asked it in the first place. 相似文献

"This paper describes the methodology used to incorporate AIDS mortality in recently revised World Bank population projections....The paper first reviews different approaches for projecting AIDS and its demographic consequences. This is followed by a summary of an epidemiological model that simulates the spread of HIV used in this analysis, and a demographic model that translates mortality from AIDS into population outcomes. These models are then used in a set of simulations, from which the effect of current HIV prevalence on projected future mortality is extracted. Finally, the extracted equations linking current HIV prevalence with future mortality indicators are applied to sub-Saharan countries with a measurable level of current HIV prevalence." 相似文献
