Product universality and design for supply chain management

We describe our experience of developing models in which the principles of design for supply chain management (DFCM) have been implemented for new product development at Hewlett-Packard Company (HP). This experience arises from the development of a new product that is scheduled to be released in 1995. A key design decision faced by the product development team was whether to use a universal module or regionally dedicated modules to satisfy global market requirements. We describe a wide range of factors—including manufacturing and logistics costs—that could be used to support the design decision; these factors associated with product and process design contribute to tolal supply chain costs. We review the analytical model used to evaluate the cost and service implications of the two design alternatives. Finally, we discuss qualitative considerations that might influence the eventual decisions as well as the lessons learned from this real world experience.     

Team‐Level Antecedents of Individuals' Knowledge Networks*

Individuals' knowledge networks are widely considered to contribute substantially to the effectiveness and efficiency of organizations. While the positive effects of knowledge networks as a primary driver of social capital have recently received considerable research attention, potential determinants of individuals' network building have not yet been adequately addressed. In this study, we investigate how certain team‐level properties affect team members' development of knowledge networks through the course of a team project. Using data from 430 team leaders and team members pertaining to 145 software development projects, we test cross‐level hypotheses using hierarchical linear modeling (HLM). The results indicate that the team's perception of the organizational knowledge‐sharing climate, the team's networking preference, and the team's perceived importance of networking for project success positively affect individuals' network building. Furthermore, a team's perception of the adequacy of its technical competency and a team's perception of the adequacy of its material resources inhibit team members' individual network development. Theoretical and managerial implications are discussed.     

Managing Cross-Functional Cooperation for New Product Development Success

This article focuses on conditions that make cross-functional cooperation in new product development projects more or less productive. We investigate 40 NPD projects in the consumer electronics and pharmaceuticals industries in which R&D and marketing played key roles. We find that the contributions of cross-functional cooperation to NPD success are contingent on the type of market and technology opportunities being pursued. More specifically, our results suggest that when a project team pursues an opportunity characterized by high levels of technological and market risks, investments in high levels of cross-functional cooperation are warranted to increase NPD success. We do not find evidence that cross-functional cooperation moderates the relationship between the openness of an NPD project towards external information and knowledge and its performance. This suggests that less integrated project teams could achieve similar results as more integrated teams in terms of processing large quantities of information and knowledge without incurring the costs that may stem from high levels of cross-functional cooperation.     

Collaborate or Compete: Examining Manufacturers' Replacement Strategies for a Substance of Concern

The recent proliferation of media reports on substances of concern has increased consumer fears, sparked scientific debate, and highlighted the need for stronger chemical regulations. When a substance of concern is identified (e.g., bisphenol‐A (BPA) in reusable water bottles), manufacturers face difficult trade‐offs in deciding whether to proactively replace the substance in their products or to defer replacement and wait to see if regulation occurs. In this study, we examine when opportunities exist for manufacturers to avoid competitively replacing (i.e., making their replacement decisions on their own), and instead, collaborate to replace a substance of concern. We model a vertically differentiated market consisting of a high‐end manufacturer and a low‐end manufacturer, both of whom sell a product that contains a substance of concern. Our analysis investigates how market dynamics (competition and consumer preferences) and external factors (replacement costs and regulatory uncertainty) influence manufacturers' collaboration, replacement, and pricing decisions. We find that when the manufacturers do not collaborate, the high‐end manufacturer can use the presence of a substance of concern to dominate the market by capturing more demand and often charging a higher price for his product than the low‐end manufacturer. Collaboration is possible when there is either a shared fixed cost savings for both manufacturers or an opportunity for the low‐end manufacturer to benefit his competitive position by motivating the high‐end manufacturer to collaborate. From a consumer perspective, although collaboration reduces consumer exposure to the substance of concern, it can decrease consumer surplus when the replacement substance is very expensive.     

The Effects of Knowledge Management on Team Members' Ratings of Project Success and Impact*

Many organizations are trying to improve the generation and utilization of knowledge. The activities associated with these efforts are identified as organizational knowledge management (KM). While much has been written about knowledge management from the organizational level, the success of such efforts over the long run will depend upon on how KM activities impact important outcomes as perceived by those at the employee level who actually implement the activities. This study used the input‐process‐output framework of team effectiveness to investigate the relationship between selected KM‐related activities on integrated product and process development team members' satisfaction with their project's success and the impact they expected it to have on the organization. The results indicate that team‐level leadership and support (i.e., inputs), along with knowledge generation and dissemination (i.e., processes), are key drivers of member performance‐related ratings (i.e., outputs). Finally, and possibly most importantly, a number of interactions were evident suggesting that the KM processes moderate the effects of the KM inputs. These findings and their implications are discussed.     

Managing the Performance Trade‐Offs from Partner Integration: Implications of Contract Choice in R&D Projects

Formal contracts represent an important governance instrument with which firms exercise control of and compensate partners in R&D projects. The specific type of contract used, however, can vary significantly across projects. In some, firms' govern partnering relationships through fixed‐price contracts, whereas in others, firms' use more flexible time and materials or performance‐based contracts. How do these choices affect the costs and benefits that arise from greater levels of partner integration? Furthermore, how are these relationships affected when the choice of contract is misaligned with the scope and objectives of the partnering relationship? Our study addresses these questions using data from 172 R&D projects that involve partners. We find that, (i) greater partner integration is associated with higher project costs for all contract types; (ii) greater partner integration is associated with higher product quality only in projects that adopt more flexible time and materials or performance‐based contracts; and (iii) in projects where the choice of contract is misaligned with the scope and objectives of the partnering relationship, greater partner integration is associated with higher project costs, but not with higher product quality. Our results shed light on the subtle interplay between formal and relational contracting. They have important implications for practice, with respect to designing optimal governance structures in partnered R&D projects.     

The Development Manager's Advisory System: A Knowledge-Based DSS Tool for Project Assessment*

This research investigates whether the knowledge-based decision support system (KBDSS) paradigm provides the necessary supporting structure and developmental framework for product development evaluation. To address the research questions posed in this study, it is necessary to develop and implement KBDSS's at specific decision points along the product development cycle. This paper describes the design, development, and implementation of a KBDSS to support a product development manager's decision concerning full-scale development of a new product. From the systems design perspective, this paper addresses the integration and innovative use of a variety of techniques for knowledge acquisition, modeling, and processing. The approach utilized obtains the benefits of normative modeling as well as the flexibility and developmental advantages of knowledge-based systems. Since its implementation, the system has been successfully used by a development manager to support his recommendation for an ongoing project. His complete satisfaction with this system served as the impetus for the design and development of a multi-expert system which was implemented at the strategic level.     

Assessing the relationship between practice changes and process improvement in new product development

This paper reports the findings of a study into the process of new product development. Specifically, it challenges the limitations of the current research into the relationship between the adoption of new tools and techniques and performance improvements in new product development. The study was carried out on a sample of manufacturing firms. Cluster analysis yields a new classification of firms, which is shown to provide a significant explanation of the relationship between levels of tool and technique usage and managers’ perceptions of improvements in outcomes. The existing evaluation of tools and techniques is shown to be deficient in not considering adoption jointly rather than singly. The study shows the benefits of a high level of overall tool and technique usage for improving key competitive objectives in new product development, but with limitations. Significantly, project costs are not improved by a high use of tools and techniques. Improved assessment of tools and techniques should be employed to reduce the gap between the rhetoric and the reality of process improvement.

The disassembly line: balancing and modeling,by S.M. McGovern and S.M. Gupta

This note addresses a problem faced by an actual firm. The problem is to decide on the optimal level of product quality. In performing the economic analysis to determine product quality level, the firm considers revenue, production costs, and research and development costs. However, this note shows that ignoring inventory costs in the analysis will lead to suboptimal product quality levels. Also, including inventory costs in the analysis will lead to reduced production lot sizes. Numerical examples are used to illustrate the results of the model.     

Collaborative Product Development: The Effect of Project Complexity on the Use of Information Technology Tools and New Product Development Practices

Collaboration is an essential element of new product development (NPD). This research examines the associations between four types of information technology (IT) tools and NPD collaboration. The relationships between NPD practices and NPD collaboration are also examined. Drawing on organizational information processing theory, we propose that the relationships between IT tools and NPD collaboration will be moderated differently by three project complexity dimensions, namely, product size, project novelty, and task interdependence, due to the differing nature of information processing necessitated by each project complexity dimension. Likewise, the moderation effects of the project complexity dimensions on the relationship between NPD practices and NPD collaboration will also be different. We test our hypotheses using data from a sample of NPD projects in three manufacturing industries. We find that IT tools are associated with collaboration to a greater extent when product size is relatively large. In contrast, IT tools exhibit a smaller association with collaboration when project novelty or task interdependence is relatively high. NPD practices are found to be more significantly associated with NPD collaboration under the contingency of high project novelty or high task interdependence. The findings provide insights about circumstances where several popular IT tools are more likely to facilitate collaboration, thus informing an NPD team's IT adoption and use decisions.     

Fostering Risk Taking in Research and Development: The Importance of a Project's Terminal Value

Large firms face a conflict in managing a portfolio of high-risk projects. When an ongoing project is thought to have a low likelihood of success, project team members take risks to improve its chances of success. However, upper-level managers who allocate resources tend to withhold resources from a project with a low likelihood of success in favor of others in the portfolio that look more promising. Because this paucity of resources influences project team members to avoid risk, the total effect of success likelihood on risk taking is conflicted. The influence on risk taking of a project's terminal value—defined as the value that remains in the firm in the event of project failure—is unequivocally positive, because both senior management resource allocation and project team risk-taking propensity are encouraged by terminal value. Thus, firms can override the ambivalent effect of likelihood of success on project decision making by focusing attention on a project's terminal value.     

OPTIMAL PROJECT SEQUENCING WITH RECOURSE AT A SCARCE RESOURCE

We develop a dynamic prioritization policy to optimally allocate a scarce resource among K projects, only one of which can be worked on at a time. When the projects' delay costs differ, the problem (a “restless bandit”) has not been solved in general. We consider the policy of working on the project with the highest expected delay loss as if the other project was completely finished first (although recourse is allowed). This policy is optimal if: (1) the delay cost increases with the delay regardless of the performance state, (2) costs are not discounted (or, discounting is dominated by delay costs), (3) projects are not abandoned based on their performance state during processing at the scarce resource, and (4) there are no stochastic delays. These assumptions are often fulfilled for processing at specialized resources, such as tests or one‐off analyses.     

Efficient Heuristics for MRP Lot Sizing with Variable Production/Purchasing Costs*

Two heuristics based on branch and bound (B&B) are developed to solve closed-loop material requirements planning (MRP) lot-sizing problems that have general product structures and variable costs. A “look ahead method'’(LAM) heuristic allows for variable production/purchasing costs and uses a single-level B&B procedure to rapidly improve lower bound values; thus, LAM efficiently uses computer-storage capacity and allows solution of larger problems. The “total average modification'’(TAM) heuristic uses B&B, applied level by level, and modified setup and carrying costs to solve the variable production/purchasing costs MRP lot-sizing problem. LAM and TAM are tested on problems and compared to heuristics in the literature. TAM may be used to solve large MRP lot-sizing problems encountered in practice.     

Sovereign Cat Bonds and Infrastructure Project Financing

We examine the opportunities for using catastrophe‐linked securities (or equivalent forms of nondebt contingent capital) to reduce the total costs of funding infrastructure projects in emerging economies. Our objective is to elaborate on methods to reduce the necessity for unanticipated (emergency) project funding immediately after a natural disaster. We also place the existing explanations of sovereign‐level contingent capital into a catastrophic risk management framework. In doing so, we address the following questions. (1) Why might catastrophe‐linked securities be useful to a sovereign nation, over and above their usefulness for insurers and reinsurers? (2) Why are such financial instruments ideally suited for protecting infrastructure projects in emerging economies, under third‐party sponsorship, from low‐probability, high‐consequence events that occur as a result of natural disasters? (3) How can the willingness to pay of a sovereign government in an emerging economy (or its external project sponsor), who values timely completion of infrastructure projects, for such instruments be calculated? To supplement our treatment of these questions, we use a multilayer spreadsheet‐based model (in Microsoft Excel format) to calculate the overall cost reductions possible through the judicious use of catastrophe‐based financial tools. We also report on numerical comparative statics on the value of contingent‐capital financing to avoid project disruption based on varying costs of capital, probability and consequences of disasters, the feasibility of strategies for mid‐stage project abandonment, and the timing of capital commitments to the infrastructure investment. We use these results to identify high‐priority applications of catastrophe‐linked securities so that maximal protection can be realized if the total number of catastrophe instruments is initially limited. The article concludes with potential extensions to our model and opportunities for future research.     

Sourcing Decisions with Competitive Suppliers and Imperfect Information

Manufacturers often must choose between outsourcing and producing internally. This choice is complex and influenced by a variety of factors, including the costs and capabilities of the potential suppliers. In addition, if the manufacturer outsources, he must design the sourcing process. We study the manufacturer's outsourcing decision, with a focus on the impact of the sourcing process on that decision. We consider a setting in which the manufacturer has imperfect information regarding the suppliers' costs and capabilities, and we assume that the manufacturer uses a two‐stage sourcing process. The first stage is the qualification stage, in which the manufacturer seeks to reduce the uncertainty regarding the suppliers' capabilities. The second stage is the supplier selection stage, in which the manufacturer selects among the qualified suppliers on the basis of price. We first characterize the optimal design of the two‐stage process, and then consider the outsourcing decision. We demonstrate several trade‐offs. Vertical integration enables the manufacturer to reduce uncertainty and extract all of the profits of production. However, outsourcing enables the manufacturer to take advantage of the (potentially) lower costs and higher capabilities of the suppliers, particularly if competition between suppliers can be encouraged. We find that the manufacturer is more likely to vertically integrate when the warranty cost and the cost of exerting effort during qualification are large, and when there is significant uncertainty regarding the suppliers' capabilities. The manufacturer is more likely to outsource when the suppliers' costs (capabilities) are low (high), and when the number of suppliers is large.     

Bringing IT Back: An Analysis of the Decision to Backsource or Switch Vendors

Whereas the decision to outsource information systems (IS) has been an important focus in IS research and practice, the decision to switch vendors or to backsource has received little attention. Evidence suggests that in practice, however, the decision to backsource or to switch vendors is becoming increasingly common as firms vie for ways to continue to cut information technology (IT) costs and improve IT service levels. This research specifically examines the factors associated with the decision to backsource or to switch vendors. Based on a sample of 160 IT managers involved with application development, we compare and contrast the perceptions of those who switched vendors, backsourced, or continued in an outsourcing relationship for application development. Our findings suggest that product quality, service quality, relationship quality, and switching costs are related to the decision to backsource application outsourcing. However, service and product quality did not influence the decision to switch vendors. Rather, firms that made the decision to switch vendors reported high levels of service and product quality but low levels of relationship quality and switching costs.

Contextual influences on international subsidiaries' product technology strategy

We seek to test a broad range of factors that influence the technology sourcing decision of international subsidiaries in acquiring product technology from outside the firm (i.e., outsourcing) versus internal development. A regression model, used to analyze data from 187 international subsidiaries in six industries and with parents based in 14 countries, identifies the environmental, strategic, configurational, and resource endowment factors that influence the technology sourcing decision. Specifically, the level of product dynamism in the subsidiary's industry and the distance between the subsidiary's primary marketing and R&D operations are associated with a greater reliance on outsourcing. A differentiation goal, a low-cost goal, along with the level of the subsidiary's human and financial resources are associated with a greater reliance on internal development.
