Managing New Product Definition In Highly Dynamic Environments, Shantanu Bhattacharya, Viswanathan Krishnan, Vijay Mahajan Nov 1998

Managing New Product Definition In Highly Dynamic Environments, Shantanu Bhattacharya, Viswanathan Krishnan, Vijay Mahajan

Research Collection Lee Kong Chian School Of Business

In highly dynamic environments, characterized by changing customer preferences and uncertainty about competitive products, managing the development of a new product is a complex managerial task. The traditional practice, recommended in the literature, of reaching a sharp definition early in the new product development (NPD) process may not be optimal, desirable or even feasible in such dynamic situations. Under high uncertainty, forcing early finalization of specifications may result in a firm getting locked into an incorrect definition. Based on our study of NPD in the high technology industry, we present a model of an approach called real-time definition, in which …

Determinant Criteria In The Ocean Carrier Selection Process, R Stephen Parker, John L. Kent Sep 1998

Determinant Criteria In The Ocean Carrier Selection Process, R Stephen Parker, John L. Kent

Journal of Transportation Management

This study examines key determinant criteria used by import and export shippers when selecting an international containership carrier. A sample of import and export shippers were asked to evaluate eighteen service characteristics based on whether or not the characteristics were required by their international containership carriers. The results of Pearson chi-square tests indicate a significant difference between import shippers and export shippers on three of the eighteen service characteristics. Import shippers were more demanding of their carriers by requiring door-to-door transportation rates, shipment expediting, and shipment tracing services.

Twenty Years Of Airline Deregulation: The Impact On Outlying Small Communities, J Richard Jones Sep 1998

Twenty Years Of Airline Deregulation: The Impact On Outlying Small Communities, J Richard Jones

Journal of Transportation Management

Many rural communities over the years have had to endure reduced levels of scheduled transportation services to the point that some have indeed experienced a cessation of services. Accompanying the deregulation of airlines in 1978 was the expressed fear that transportation services would continue to spiral downward and various communities would lose their population bases. This study investigates the two decades of airline deregulation and the impact that that 1978 legislation has had on small communities that are situated 100 air miles or more from any hub airport. Chief among the findings are: (1) that service levels have indeed deteriorated …

An Exploratory Analysis Of Factors Driving Intermodal Transportation Usage, Philip T. Evers, Carol J. Emerson Apr 1998

An Exploratory Analysis Of Factors Driving Intermodal Transportation Usage, Philip T. Evers, Carol J. Emerson

Journal of Transportation Management

The purpose of this study is to investigate certain aspects of a transportation choice model proposed by Krapfel and Mentzer (1982) pertaining to the influence of shipper perceptions on the selection of a mode. Specifically, this study attempts to identify the impact that shipper perceptions of intermodal and over-the-road truck service, as well as other characteristics of the shipper, have on intermodal usage. The research findings support the notion that shipper perceptions affect modal usage and indicate areas in which intermodal providers should focus their attention to improve intermodal usage.

Union Pacific/Southern Pacific Merger: Impact On Shippers, Paul D. Larson, H Barry Spraggins Apr 1998

Union Pacific/Southern Pacific Merger: Impact On Shippers, Paul D. Larson, H Barry Spraggins

Journal of Transportation Management

In the Summer of ‘96, Union Pacific Railroad merged with Southern Pacific to create the largest American railroad. Controversy continues to surround the merger. This paper reports results of a recent merger-impact survey. Survey respondents were rail and intermodal shippers. Among the interesting research findings are the following: (1) while shippers report a negative impact due to less rail competition, trackage rights granted to Burlington Northern/Santa Fe have failed to dampen this impact; (2) railroad service has deteriorated, but freight rates have remained stable; and (3) service problems are more severe for rail, as opposed to TOFC/COFC, shippers.

The Tqm Paradox: Relations Among Tqm Practices, Plant Performance, And Customer Satisfaction, Thomas Choi, Karen Eboch Dec 1997

The Tqm Paradox: Relations Among Tqm Practices, Plant Performance, And Customer Satisfaction, Thomas Choi, Karen Eboch

Karen Eboch

We empirically examine a mediational model of TQM, in which TQM practices have a direct impact on customer satisfaction and an indirect impact mediated through plant performance. We adopt a survey approach using the data from 339 manufacturing companies. We first establish convergent validity, discriminant validity, and reliability of the constructs. We then examine the model using LISREL 8.10. The results suggest paradoxical relations among TQM practices, plant performance, and customer satisfaction. TQM practices have a stronger impact on customer satisfaction than they do on plant performance. Further, the plant performance, as described in the mediational model, fails to show …
