Uncertainty perception in bidding for Product-Service Systems under competition

This research investigates what impact of uncertainty perception arising from the existence of competition has on the pricing decision for Product-Service Systems (PSS) under uncertainty. PSS provision is an increasingly important area for many businesses and competition increases cognitive pressures on providers even further. We present an experimental study with industrial costing and bidding experts from the defence and aerospace sector. The study consisted of an experimental set-up via two questionnaires which differed in the existence of competition in the bidding scenario. The findings showed that bidding decision makers changed their evaluation of the cost estimate due to the introduction of competition but kept their evaluations of the profit margin and price bids constant. Furthermore, the participants listed the relevant sources of uncertainty that influenced their decision-making process. This research contributes to the literature in two ways. First, our findings showed that predictions from current theory regarding decision-making of cost estimation and pricing are not confirmed when competitively bidding for PSS. Second, we show uncertainty sources that influenced the decision makers and identified p the importance of internal processes of the PSS provider and environmental uncertainty.

Lean production and supplier relations: a survey of practices in the Aragonese automotive industry

This paper analyzes the main results of a survey to 28 automotive suppliers in the Spanish region of Aragón. It has been found in a regression analysis that the rotation of tasks and teamworking are positively correlated with the training and the use of modular components. Nearly half of the companies cooperate with customers, suppliers, and technological centers to improve their production processes but only two companies cooperate with their customers in component development and design which indicates an underinvolvement of the surveyed companies with the automotive manufacturers. The companies are much more integrated with the automakers in the delivery process, since more than half of the companies have daily deliveries and directly to the assembly line of the automaker.     

Missing link in competitive manufacturing research and practice: Customer-responsive concurrent production

Manufacturing management, in its evolving theory, research, and practice, is plagued by mindsets that are narrowly focused on factory efficiency, with insufficient emphasis on customer responsiveness and its dominant role in competitiveness. In our presentation of these issues we describe and advocate customer-oriented manufacturing practices, in the realm of factory infrastructure. This approach, which we call concurrent production or CP, involves configuring, equipping, and operating factories with a primary focus on synchronization with customer demand. We call on OM researchers to consider these topics in furthering the cause of market competitiveness.

The threat of counterfeiting in competitive search equilibrium

This paper studies counterfeiting of bank notes in a monetary model under competitive search. The application of the refinement scheme proposed by Guerrieri et al. (2010) shows that there is no equilibrium with counterfeiting. However, due to the entry margin, counterfeiting poses a threat to the existence of a monetary equilibrium: there is no monetary equilibrium if the cost of producing counterfeits is low enough. Moreover, the threat of counterfeiting can generate an endogenous resalability constraint. An extension of the model is provided which allows the threat of counterfeiting to materialize, in that some buyers cannot observe the offers, and therefore search randomly. Counterfeit notes are produced by those buyers who randomly search.     

Work intensification and employee involvement in lean production: new light on a classic dilemma

Abstract

This paper contributes to the literature on lean production by exploring whether and how the involvement of employees in continuous improvement and their work outcomes are jeopardized by the intensification in the work pace that stems from the elimination of non-value added activities. The research setting is the application of a lean production system, World Class Manufacturing, to 24 Italian plants of a global carmaker. The research has found that work intensification limits employee involvement in continuous improvement, and plays a crucial role in enabling employees to experience higher personal efficacy, better work performance and higher employee satisfaction. However, worker intensification does not have a direct negative impact on employees’ satisfaction about their working condition. A supportive team environment and a mature implementation of lean production at a plant level mitigate the tension between employee involvement and intensification of the work pace. Two main implications of these findings have emerged. Ambivalence in lean production is a temporary response of the workforce that can gradually diminish when the plant reaches a systemic level of application of lean organization principles. In order to diminish the coercive function of lean production, managers should apply tools and practices that require more employee involvement and a supportive team environment.     

Reconceptualizing the effects of lean on production costs with evidence from the F-22 program

A central tenet in the theory of lean production is that the implementation of lean practices will reduce waste and thereby decrease costs. However, not all lean implementations have produced such results. Apparently, this effect is moderated by several factors, potentially even to the point of reversal. It is important to increase our understanding of how this might occur. In this paper, we explore how novelty, complexity, instability, and buffering affect the relationship between lean implementation and production costs. An interest in these factors drew us to study the case of Lockheed Martin's production system for the F-22, an extremely complex and innovative product. To build theory, we synthesize our empirical data from the case with other existing theory, such as theories of learning and complexity. Through this analysis, we develop a revised framework that reconceptualizes the effect of lean on production costs and use it to develop 11 propositions to direct further research. Included among these are propositions about how the timing, scale, and extent of lean implementation can regulate the benefits of lean. Furthermore, when the objective of lean is construed as the provision of value, we propose that this value is an emergent property of a complex process, different from the mere sum of the values provided by its constituent tasks. Therefore, the elimination of tasks will not guarantee cost reduction, and lean may provide even greater value by incorporating some aspects of agile manufacturing. Overall, we develop a fuller range of the effects of lean practices on production costs and illuminate how operations managers might control key variables to draw greater benefits from lean implementation.

Effects of HRM practices,lean production practices and lean duration on performance

Abstract

The purpose of this research is to investigate the structural relationships between HRM practices, lean production practices, operational performance and firm performance of manufacturing firms that have implemented lean production. The data were collected from the firms operating in Sri Lanka, which fulfilled the selection criteria set for the study. Statistical techniques were used to test the hypothesized relationships. It was found that lean production practices and operational performance mediate the relationship between HRM practices and firm performance; lean duration moderates the relationship between HRM practices and lean production practices in such a way that the longer the duration, the greater would be the adoption of lean production practices. The essential contribution of the findings lie in presenting empirical data valuable for the advancement of research in HRM as well as for making decisions on people management when implementing advanced manufacturing technologies.     

Lessons from seru production on manufacturing competitively in a high cost environment

High capital and labor costs, coupled with high rates of technological and competitive change, present challenges for manufacturers in developed countries, often spurring them to offshore production to low cost sources. However, the electronics industry provides an exception to this trend, where dynamic, high cost conditions have given rise to a new production system – seru – a cellular assembly approach. Seru evolved as an alternative to lean systems approaches, manifesting important differentiated system design choices that appear to offer promise for manufacturing in dynamic, high-cost markets. This paper reports the results of in-depth, longitudinal case studies of two electronics giants who have implemented seru. The case studies describe seru's fundamental extensions to, and departures from, lean production, agile production, and group technology-based cellular manufacturing. We explain how Sony and Canon have applied seru to improve productivity, quality, and flexibility in ways that have enabled them to remain competitive. In addition, our findings elaborate the theory of swift, even flow, with implications for future research of trade-offs related to production efficiency, responsiveness, and competitiveness in high-cost, technologically dynamic markets.
