Enterprise Resource Planning (ERP) Systems and the Manufacturing-Marketing Interface: An Information Processing Theory View

The manufacturing-marketing (MM) interface has received substantial consideration in the operations management literature; however, relatively little attention has been paid to the role of information systems in facilitating MM integration. As integrated cross-functional systems, enterprise resource planning systems (ERP) are well-suited to provide MM integration. Based on information processing theory, the central proposition of this paper is the greater the interdependence between manufacturing and marketing, the greater the benefit of ERP. Specifically, H1 states that the greater ERP-enabled coordination between manufacturing and marketing, the greater the benefit of ERP to the plant. H2 states that the degree to which ERP-enabled manufacturing-marketing coordination improvements are realized, depends on the amount of interdependence between manufacturing and marketing. Using multiple regression, the model is tested on survey data from 107 manufacturing plants running ERP. The data support H1 and H2. These findings support the general proposition that interdependence between functions is one factor that influences the degree to which organizations reap benefits from their ERP investments. Based on the ERP literature, the model controls for the amount of time that ERP has been running in the plant; This factor was found to be insignificant in the model. However, exploratory analysis finds that time is associated with other ERP benefits

Negotiation, Email, and Internet Reverse Auctions: How Sourcing Mechanisms Deployed by Buyers Affect Suppliers’ Trust

The Internet has made a wealth of new tools available to the industrial buyer. However, researchers have suggested that computer mediated interaction with suppliers may not be conducive to strong supplier relationships in general and to trust in particular. This paper compares two computer-mediated sourcing tools (email negotiation and Internet reverse auctions) with face-to-face negotiation. Information richness theory suggests that the different media will produce different impacts relating to sellers’ trust in buyers. Data are generated with a simulation experiment using 117 subjects. We found that information richness affects seller-buyer trust: Sellers who used face-to-face negotiation, the richest medium in the study, always reported higher trust in their buyer counterparts than did sellers using Internet reverse auctions. There were also some trust advantages of face-to-face negotiation over email and limited advantages of email over reverse auctions. We also found that procurement complexity influences the relationship between information richness and trust. As hypothesized, when face-to-face negotiation is used, procurement complexity has no effect on seller trust. When reverse auctions are utilized, the greater the complexity of the purchase, the less the seller trust. However, when email is used, greater procurement complexity is associated with greater seller trust, and there are no differences in trust between the email and face-to-face channels. Finally, we found that sellers’ trust in buyers is positively associated with sellers’ desire for future dealings with the buyer

The Operational Impacts of Chief Supply Chain Officers in Manufacturing Firms

Many firms have elevated their supply chain management decision-making responsibilities through the creation of ‘Chief Supply Chain Officer’ (CSCO) positions. This is widely attributed to the recognition that superior supply chain operations can generate a competitive advantage. Prior studies have found that firms with CSCOs outperform firms without CSCOs along many financial dimensions. However, these prior efforts did not examine the pathways by which these improvements occur. This study addresses this gap in the literature by investigating whether supply chain characteristics of manufacturing firms differ within firms with CSCOs. To explore this, we investigate the relationship between CSCOs and operational dimensions of supply chain performance using data from the 10-year period between 2008 and 2017. We find that the presence of a CSCO in a firm is associated with shorter cash conversion cycles, lower levels of operational slack, and larger buffers of inventory during periods of high market instability

Understanding Project Champions’ Ability to Gain Intra-Organizational Commitment for Environmental Projects

A key enabler of environmental projects is the ability of the project champion to gain commitment to the project from other stakeholders in his or her organization. This paper develops a model of commitment-gaining success that is based on intra-organizational influence theory. The model also includes the project payback, customer pressure, government regulation, top management support and the project champion’s position in the organizational hierarchy. The model was tested using survey data from 241 environmental professionals describing their attempts to gain the buy-in of purchasing managers, operations managers, industrial engineers and others for environmental projects. The results (obtained from hierarchical regression analysis) show that intra-organizational commitment is positively associated with the project champion’s influence behavior—in particular, the champion’s use of three influence tactics (inspirational appeals, consultation and rational persuasion) and avoidance of a fourth tactic (ingratiation). Commitment is also positively associated with project payback and with top management support for the environment and negatively associated with environmental regulation. The paper contributes to the OM knowledge base of environmental project implementation by bringing new theory to bear on the topic, by focusing on individual-level, rather than organization-level, variables and by taking a confirmatory, large sample approach which complements extant exploratory research. In addition, the paper contributes to the OM field by evaluating various antecedents to cross-functional integration. The results also provide specific guidance to those who champion environmental projects within their companies

Widespread Over-Expression of the X Chromosome in Sterile F1 Hybrid Mice

The X chromosome often plays a central role in hybrid male sterility between species, but it is unclear if this reflects underlying regulatory incompatibilities. Here we combine phenotypic data with genome-wide expression data to directly associate aberrant expression patterns with hybrid male sterility between two species of mice. We used a reciprocal cross in which F1 males are sterile in one direction and fertile in the other direction, allowing us to associate expression differences with sterility rather than with other hybrid phenotypes. We found evidence of extensive over-expression of the X chromosome during spermatogenesis in sterile but not in fertile F1 hybrid males. Over-expression was most pronounced in genes that are normally expressed after meiosis, consistent with an X chromosome-wide disruption of expression during the later stages of spermatogenesis. This pattern was not a simple consequence of faster evolutionary divergence on the X chromosome, because X-linked expression was highly conserved between the two species. Thus, transcriptional regulation of the X chromosome during spermatogenesis appears particularly sensitive to evolutionary divergence between species. Overall, these data provide evidence for an underlying regulatory basis to reproductive isolation in house mice and underscore the importance of transcriptional regulation of the X chromosome to the evolution of hybrid male sterility

Comparative genomic and phylogeographic analysis of Mycobacterium leprae

Reductive evolution and massive pseudogene formation have shaped the 3.31-Mb genome of Mycobacterium leprae, an unculturable obligate pathogen that causes leprosy in humans. The complete genome sequence of M. leprae strain Br4923 from Brazil was obtained by conventional methods (6 x coverage), and Illumina resequencing technology was used to obtain the sequences of strains Thai53 (38 x coverage) and NHDP63 (46 x coverage) from Thailand and the United States, respectively. Whole-genome comparisons with the previously sequenced TN strain from India revealed that the four strains share 99.995% sequence identity and differ only in 215 polymorphic sites, mainly SNPs, and by 5 pseudogenes. Sixteen interrelated SNP subtypes were defined by genotyping both extant and extinct strains of M. leprae from around the world. The 16 SNP subtypes showed a strong geographical association that reflects the migration patterns of early humans and trade routes, with the Silk Road linking Europe to China having contributed to the spread of leprosy

Using Life-Cycle Assessment Data to Evaluate the Carbon Footprints of Business Processes: A Tutorial

Using a case example from supply chain management, this article presents the essential concepts for faculty who are interested in helping students develop literacy in this area. Faculty can adapt the example to suit the particular objectives and circumstances of their classrooms

Metro Meals on Wheels Treasure Valley Employs a Low-Cost Routing Tool to Improve Deliveries

In this paper, we discuss a project in which we developed a spreadsheet-based system that interfaces with a no-fee driving-directions application programming interface to quickly and accurately build a travel time and distance matrix and then rapidly determine near-optimal delivery-route schedules using a modified genetic algorithm. To the best of our knowledge, the method we used to create the travel matrix had not been employed previously in an academic study. The tool was tested and refined in a humanitarian setting—a local branch of the Meals on Wheels Association of America (now Meals on Wheels America), an organization that combats hunger and poverty by providing food to individuals who are in need. The tool, which is currently being utilized by Metro Meals on Wheels Treasure Valley, has substantially reduced the time required to plan deliveries and has also reduced the delivery driving times by approximately 15 percent
