Optimal Regulation of Cooperative R&D Under Incomplete Information

A regulator offers a cooperation contract to two firms to develop a research project. The contract provides incentives to encourage skill-sharing and coordinate subsequent efforts. Innovators must get informational rents to disclose their privately known skills, which results in distorting R&D efforts with respect to the first-best level. When efforts are strategic complements, both efforts are distorted downwards. By contrast, when efforts are strategic substitutes, the effort of the firm with most valuable skills is distorted downwards (to decrease rents) and the effort of the other firm is distorted upwards (to compensate the previous efficiency loss).     

Remodularization of a Product Line: Adding Complexity to Project Management

Faced with ever-tighter schedules, product development professionals employ various methods for staying at least one step ahead of the competition. In particular, an autonomous, cross-functional team offers an effective structure for meeting the sometimes conflicting objectives of timely delivery of a high-quality, easily manufactured product. To complicate matters, however, companies must manage not only individual projects, but also entire product lines. Changes in product and process technology eventually necessitate revamping of the product architecture—that is, the remodularization of a product line. Can an autonomous project team provide the long-term perspective necessary for such efforts? Or, does remodularization of a product line require centralized oversight by functional management? Mats Lundqvist, Niklas Sundgren, and Lars Trygg explore this issue by examining product development efforts at two Swedish manufacturing companies. Specifically, their study explores this research question: Does a high degree of project autonomy limit the possibility for effective remodularization of product architecture? Both companies were involved in remodularization projects with stringent requirements for project cost and duration, but the companies employed markedly different managerial models in these efforts. One company took a centralized approach, except that two design engineers worked full time on the project. The other company used the autonomous model, with two exceptions: functional managers worked closely with some project members during the task specification phase of the project; and the project leader, though a heavyweight in many respects, did not have formal decision-making power. The latter project demonstrated that an autonomous project team can maintain a long-term perspective during development of a product. In other words, this project team was able to meet challenging time and cost objectives while developing a product consisting of highly compatible modules and subsystems. Although a centralized management approach might be expected to offer greater efficiency, the company using that approach failed to meet project goals for development time, product cost, and long-term product line effectiveness. However, the shortcomings of that effort are more directly attributable to the management style of the project leader than to the management structure employed.     

Are really new product development projects harder to shut down?

Just as a good houseguest knows when it's time to say good-bye, effective managers must recognize when it's time to terminate a new product development (NPD) project. As a product progresses toward commercialization, a manager's reluctance to terminate a failing project becomes increasingly expensive. Despite this growing expense, however, many managers are reluctant to shut down failing NPD projects. Jeffrey Schmidt and Roger Calantone hypothesize that this reluctance may be even more pronounced for innovative new products than for incremental NPD efforts. They suggest that perhaps the excitement that really new products engender within a company makes managers more reluctant to shut down the NPD project, even in the face of clear-cut evidence that the project is not a winner. To test these assumptions, they conducted a decision-making experiment in which managers were asked to make go/no-go decisions at each stage in a hypothetical NPD project. One project involved an innovative new product; the other project involved an incremental development—that is, a line extension that offered only marginal size and cost reductions compared to current models. At the outset of the experiment, participants were given market share and profit objectives for assessing the new product's performance. At each stage in the hypothetical NPD project, the participants then received updated performance data. The performance data provided to participants was identical for the two hypothetical projects, and fell increasingly farther below the performance objectives as the project progressed. The results of the experiment support the hypothesized relationship between product innovativeness and managers' reluctance to terminate a failing NPD project. Given identical, poor, performance forecasts, the managers who participated in this experiment were more optimistic about the likelihood of success, were more committed to the project, and were more likely to opt for continuing the project when it involved the more innovative product. In fact, the participants were more likely to allow the highly innovative NPD project to proceed all the way through commercialization, notwithstanding the progressively ominous performance feedback.     

Exchange rate regimes and import pricing

To what extent exchange rate variations are passed through into import prices has been on the research agenda over the past decade. Research efforts have focused on the very existence of pricing to market and on differences in pass-through behaviour between industries. Much less research has been devoted to the factors behind variations in pass-through behaviour within industries, and to changes in this behaviour over time. The change of exchange rate regime in Sweden in 1992 is used here to illustrate how the interaction between alternative exchange rate regimes, fixed and floating, and pricing behaviour affects pass-through behaviour. The study concentrates on the passenger car industry.     

How state influence on project work organization both drives and mitigates gendered precarity in cultural and creative industries

This article develops an understanding of gendered precarity in project work by considering how the transfer of risk from employer to worker is shaped by the contextual pressures of state policy and the organization of the industrial field. The focus is the organization of project work as a condition underpinning the shifting of this risk in a mature field of precarious employment, the cultural and creative industries (CCIs). Our empirical exploration in Film/TV in the UK and Germany, and Dance in Sweden and the Netherlands, examines the dynamic interplay between state policy domains (cultural, social and regulatory), industry-level funding bodies or ‘transaction organizers’ and the cultural processes of CCI project networks. We argue that state-led influences both drive and mitigate the transfer of risk in project work as gendered, racialized and classed. Our framework contributes to broadening employment literature on risk and the disadvantaging capacity of networks to hoard opportunities in project-based labour markets.     

Metrics for Measuring Product Development Cycle Time

As global competitive pressure increases and product life cycles compress, many companies are trying to shorten their product development cycles. Firms are implementing a wide variety of different techniques, management processes and development strategies in their quest for shorter development cycles. We read anecdotal accounts of some efforts that herald great success stories but seldom hear about any failures. Unfortunately, some of the companies changing their development processes do so without any a priori basis for determining whether the process change will have helped or hindered them. The firm implements the new process without having a cycle time performance baseline against which to compare results from the new process. In this article, Abbie Griffin presents a method for obtaining product development cycle time performance baselines. She also demonstrates how to use them to either forecast expected project duration, given that you have not changed your development process, or determine whether a process change has actually decreased development cycle times.     

Responsibility and authority in the matrix organization or is ambiguity a good thing?

Abstract. Ambiguous definition of roles in the matrix is sometimes advocated, but there is evidence that ambiguity can lead to stress and is often experienced as a major problem. A popular alternative is to define the responsibility of project managers without giving them any formal authority. For this to be workable the selection of project managers and the establishment of their function must ensure that they have other sources of effective power. But there is a third option, which is to define responsibility and authority in the matrix clearly and consistently. This approach reveals a range of choice in the authority to be given to project managers, and can be supplemented by the technique of responsibility charting. Finally, choices will need to be made and the paper sets out some of the relevant considerations to be taken into account.     

The mode of exchange and shaping of markets: Distributor influence in the Swedish post-war food industry

This paper addresses the associations between the mode of exchange and the configuration of market actors and exchange objects through a historical case study of the introduction of self-service retailing in the private food retail trade in Sweden. The changes in the mode of exchange reported in the case resulted from organizing efforts involving both retailers and a major wholesaler. These efforts were directed towards two main areas: the material framing of the exchange situation, e.g. the redesign of store facilities, interiors and the pre-packaging of goods, and the agency of the involved actors, e.g. information campaigns and education directed towards retailers and consumers. Through this process, a network of associations was forged that inter-defined the mode of exchange, the market actors and the exchange objects. The paper contributes to extant literature on the shaping of markets by empirically examining the associations constituting modes of exchange and the process through which these associations are forged. A central finding is that the introduction of self-service was elaborately intertwined with changes in the characteristics of the actors and objects of exchange.     

Technology as the language of schooling: utopian visions of technology in Swedish general education in the 1960s

In the state-of-the-art Glass Project run by the Swedish National Agency for Education during the second half of the 1960s, a new type of comprehensive technology education was developed. The project had little impact on school practice and was soon forgotten about. However, the project is interesting from several points of view. First, it elaborated an interesting curricular idea where school activities were to centre around technology, thus creating a meaningful whole for the pupils, a sort of “language of schooling”. Second, the Glass Project illustrates a utopian logic of educational reform. The school had become an important area of reform in the mid-twentieth century, and in this the pedagogy of the “old school” was heavily criticised. Technology education clearly became a tool for progressive ideas in Sweden in the 1960s.     

Tying the pieces together: A normative framework for integrating sales and project operations

Synchronizing sales efforts with project operations, such that (1) there is a steady flow of work that can be completed in a non-chaotic project environment, (2) resources maintain high utilization, and (3) desired deliverables reach customers within the promised lead-time, is extremely difficult. This paper proposes a normative approach to uniting the sales process with project operations capacity by coordinating movement of potential customers through the sales funnel with the company's internal project capacity. It also addresses contingencies with respect to company throughput as a result of changes in managing the market, the sales funnel, and project operations, while taking into consideration variation in scheduling as well as in managing project task and duration uncertainty.     

Uncertainty and stress in an R&D project environment

Abstract
R&D project managers work in an environment in which the uncertainty and complexity of engineering development problems are an important source of episodic job stress. A study of the US. Navy's top major project R&D managers (N = 118) was conducted to test the use of various coping skills and social support as preventive stress management techniques for this population. It was found that perceived environmental uncertainty (PEU) had a direct, positive effect on psychological distress of these project managers while social support had a therapeutic effect on their experience of burnout. While problem focussed coping had a small, positive effect on burnout, neither coping skills nor social support were found to have a primary prevention effect upon perceived environmental uncertainty (PEU).
Engineering managers engaged in high technology R&D are confronted by a wide range of uncertainties, risks and changing demands that give rise to the stress response with its attendant physiological and psychological changes (Asterita, 1985). Adams (1980) has argued that an episodic versus chronic dichotomy of stressors is valuable because it distinguishes between intermittent stressors of finite duration (episodic) and ongoing stressors of indeterminant duration (chronic). This article reports the results of a study of uncertainty as an episodic work stressor for the U.S. Navy's high technology R&D project managers. The results suggest that R&D project managers should develop social support systems and structures to maintain well-being and avert distress and strain.     

When the purchasing agent is a committee: Implications for industrial marketing

This article describes a research project that investigated the relationship between the purchasing decision process occurring within a firm and intrinsic factors relating to the product. The study determined the effects of product complexity on the procurement process and identified those dimensions of complexity to which participating departments are sensitive. The results of the study provide information of great value to the theoretical development of buying centers as well as to those involved in targeting industrial marketing efforts.

Making real options work for practitioners: a generic model for valuing R&D projects

We propose a generic valuation framework for the appraisal of R&D projects based on real option theory. The added value of this approach is the presentation of a model that was implemented in a manner that allows corporate decision makers to use real options in an intuitive and standardized way. The project valuation procedure is separated into three main phases: project modeling, data and input collection, and result generation and analysis. The project model represents the structure of the real world R&D project with its investments, expected results, and decisions that need to be taken conditionally on the outcomes of research activities. The project model is represented in the form of a decision tree, where different research results or taken decisions lead to new branches. In this way, every possible situation the project can pass through can be represented. Uncertainties are separated into market uncertainties (e.g., market prices) and project specific, private uncertainties (e.g. uncertainty of research results). For both uncertainties, event trees are constructed which are then combined and merged with the above mentioned decision tree in order to represent the value evolution of the R&D project under given decisions and uncertainties. For every possible state of the project the real option value is calculated. By creating multidimensional trees, a multitude of decision steps and various kinds of real options (e.g., continue, expansion, switch, abandonment) can be modeled. The calculation complexity for the decision trees is given. From the tree structure we can calculate the real option value of starting an R&D project, i.e., the value of undertaking the first investment and thus acquiring the subsequent decision opportunities given by the completion of the first research effort. Furthermore, the optimal exercise strategy is derived from the decision tree. The exercise strategy gives the manager the possibility to have an a priori overview of where an R&D project may lead to, which decisions need to be taken in which circumstances, and when the project needs to be stopped in order not to generate losses. In an in‐depth case study we use an illustrative R&D project to set up and discuss the three phases of project modeling in the real options framework: building the multidimensional decision tree, input generation, and calculation of the real option value as well as the optimal strategy for the R&D project.

Crowdsourcing without profit: the role of the seeker in open social innovation

Crowdsourcing has increasingly been studied as an open innovation (OI) mechanism by which organizations (seekers) engage with an external crowd of potential solvers. Previous crowdsourcing research has focused on solvers and their individual motivations, providing few insights as to why and how seekers use crowdsourcing, and how these choices affect the value that might be realized from these efforts. Prior research has also emphasized profit‐seeking firms, despite the use of OI practices by public sector organizations to achieve societal benefits. This paper examines the organizational and project‐level choices of government agencies that crowdsource from citizens to drive open social innovation, and thus develop new ways to address societal problems, a process sometimes termed ‘citizensourcing.’ Using rich data from 18 local government seekers that use the same intermediary, we develop a model of seeker crowdsourcing implementation that links a previously unstudied variance in seeker intent and engagement strategies to differences in project team motivation and capabilities, in turn leading to varying online engagement behaviors and ultimately project outcomes. Our study compares and contrasts governmental and corporate crowdsourcing to reveal that the non‐pecuniary orientation of both seekers and solvers means that the motives of government crowdsourcing are fundamentally different from corporate crowdsourcing, but the process in our sample more closely resembles that of a firm‐sponsored community rather than government sponsored contests. More generally, we show how seeker organizational factors and choices shape project‐level implementation and success of crowdsourcing efforts, as well as provide insights for OI activities of other smaller, geographically bound organizations.     

Technical Professionals in Cross-functional Teams: Their Quality of Work Life

The idea that R&;D professionals typically spend a considerable amount of their time working as members of teams makes sense. After all, plenty of research indicates that the use of cross-functional teams improves the effectiveness of product development efforts. However, the increasing use of cross-functional teams raises an important question for researchers and R&;D practitioners: Does the use of cross-functional teams improve the quality of work life for technical professionals?Rene Cordero, George F. Farris, and Nancy DiTomaso address this question in study of 1,714 R&;D professionals working on projects. They suggest that being a member of a cross-functional team may be more demanding than working as a member of a functional project group. On the other hand, they expect that working on a cross-functional project team may be more rewarding than working in a functional project group. Their study tests these hypotheses by examining the relationships between measures of the extent to which respondents work on cross-functional teams and five measures each of the participants’ job demands and positive job outcomes.The study identifies positive relationships between working on cross-functional teams and the five positive job outcomes studied: job growth, job security, membership in successful teams, earning money, and job satisfaction. The study finds less consistent and weaker relationships between working on cross-functional teams and the five job demands studied. Specifically, the study identifies positive relationships between working on cross-functional teams and the following job demands: effort, job involvement, and considering a lot of difference of opinion. The results of this study do not find a conclusive relationship between cross-functional team membership and time pressure. And contrary to expectations, the study finds a negative relationship between working on cross-functional teams and job stress.Comparing the responses of participants who work on project teams with those who do not, the results of the study indicate that respondents who work on project teams face greater job demands than positive job outcomes. However, working on cross-functional teams seems to increase positive job outcomes more than job demands. In other words, working on cross-functional teams appears to increase the quality of work life for the technical professionals in this study.     

The boundary relevance of the project manager's job: findings and implications for R & D management

Much of the stress and conflict in the project manager's job can be attributed to the boundary nature of that position. This study explores the relevance of recent developments in organizational role theory for clarification and understanding of the project manager's job. Findings are reported from a study which show that traditional management thought is inadequate for understanding the factors which regulate the project manager's behavior. One must recognize the boundary relevance of the project manager's role in order to avoid organizational or administrative arrangements that would be undesirable for project management. Several implications, which logically follow from the theory and findings on boundary role behavior, are noted for their relevance for R & D management.
