This paper argues that for firms marketing industrial goods, the terms—system, product, service and commodity—are better employed to characterize the way the firm competes rather than any intrinsic attributes of what it markets. It is shown that the same hardware can be transacted as a system, service, product of commodity, and the nature of the most popular transaction changes over time. The nature of these shifts and how the firm needs to match its strategy to reflect them are discussed, and the special case of diversified firms in industries subject to rapid transaction shifts is taken up. It is suggested that for such firms a divisional structure based on the type of transaction—‘transaction divisions’—rather than the conventional Product Type divisions may make the firm better able not only to match its strategy to such shifts but also better able to anticipate them. 相似文献

New bounds are obtained for the variance of the minimum variance unbiased estimator of p i n inverse sampling. A generalized procedure for further improving the bounds is also discussed. 相似文献

The effects of non-normality on type-I and type-II errors in a one-way random model are investigated for moderate departures
from normality. It is found that the probabilities of both errors are more sensitive to the kurtosis of between group effects
than that of within group effects. 相似文献

Sathe (1977) derived sharper variance bounds for inverse sample unbiased estimator of the negative binomial parameter p. In the present writing improved upper/lower variance bounds are achieved and the relative improvement is numerically illustrated. 相似文献
