Despite the recognition of how important expertise coordination is to the performance of software development teams, understanding of how expertise is coordinated in practice is limited. We adopt a configural approach to develop a theoretical model of expertise coordination that differentiates between design collaboration and technical collaboration. We propose that neither a strictly centralized, top-down model nor a largely decentralized approach is superior. Our model is tested in a field study of 71 software development teams. We conclude that because design work addresses ill-structured problems with diverse potential solutions, decentralization of design collaboration can lead to greater coordination success and reduced team conflict. Conversely, technical work benefits from centralized collaboration. We find that task knowledge tacitness strengthens these relationships between collaboration configuration and coordination outcomes and that team conflict mediates the relationships. Our findings underline the need to differentiate between technical and design collaboration and point to the importance of certain configurations in reducing team conflict and increasing coordination success in software development teams. This paper opens up new research avenues to explore the collaborative mechanisms underlying knowledge team performance.

Consumers possess a mental account that stores the worth of items purchased and yet to be consumed. Reference prices act as the book values of these items. Movements in the account—the comparison between the reference price and the price paid at entry, and the comparison between the benefit of consumption and the reference price at exit—yield hedonic benefits. The reference price is determined by a psychological process of adaptation to the price evoked by the trade. The model is integrative, in that it explains a wide array of observed anomalies such as sunk-cost effects, payment depreciation, reluctance to trade, preference for pre-payment, and the flat-rate bias. The model also generates new testable implications

Degree of parallelism is an important factor in workflow process management, because it is useful to accurately estimate the server costs and schedule severs in workflow processes. However, existing methods that are developed to compute degree of parallelism neglect to consider activities with uncertain execution time. In addition, these methods are limited in dealing with the situation where activities in multiple concurrent workflow processes use shared resources. To address the limitations, we propose a new approach to analyzing degree of parallelism for concurrent workflow processes with shared resources. Superior over the existing methods, our approach can compute degree of parallelism for multiple concurrent workflow processes that have activities with uncertain execution time and shared resources. Expectation degree of parallelism is useful to estimate the server costs of the workflow processes, and maximum degree of parallelism can guide managers to allocate severs or virtual machines based on the business requirement. We demonstrate the application of the approach and evaluate the effectiveness in a real-world business scenario.

Purpose – The purpose of this paper is to enrich our understanding of entrepreneurs’ daily deeds, tasks and activities. The research investigates the ways in which entrepreneurs seize opportunities and gain knowledge from the start to the expansion of their ventures.Design/methodology/approach – Two case studies were developed based on a longitudinal fine-grained analysis of two ventures over two years. Entrepreneurs’ success and learning were modeled in line with grounded theory methodology. Data were collected from both primary and secondary sources in the form of semi-structured interviews and archival documentation.Findings – The authors develop an original conceptual framework that consists of ten entrepreneurial learning opportunities and four knowledge development modes. There are ten generic types of actions that entrepreneurs take. There are then four distinctive ways to transform these experiences into knowledge. The model is assessed in absolute terms and relatively to existing taxonomies.Research limitations/implications – The findings question the premises on which entrepreneurial learning research traditionally relies. Opportunities can be open-ended rather than purely instrumental. Similarly, knowledge can be emerging as much as it can be espoused. This opens-up space for further research.Practical implications – For practitioners, the findings suggest new ways for making sense of the daily experience of their entrepreneurial endeavor. The learning modes suggested can be used by coaches and mentors when helping entrepreneurs in their venture.Originality/value – The research provides empirical evidence of what entrepreneurs do. This may help cast traditional debates about what there is to do (logical necessity) and what there is to know (a priori knowledge) in a new light.

Little research has focused on the way an innovation ecosystem emerges and specifically what processes and tools support it. We argue that as in innovation development processes, experimentation may generate knowledge and reduce the uncertainties associated with this emergence. Based on a longitudinal study of hydrogen energy solutions that require a novel ecosystem, we outline four specificities of the experiments performed, designated as complete solution experiments, and their role in this emergence. They: 1) involve all the players required so as to deliver and operate a complete solution; 2) target real customers using the innovation in real conditions over a significant period of time; 3) are highly refined (components and complements are representative of an industrial offer); 4) are transparent on how the data generated will be exploited and shared with all the players who commit to the experiment, who are thus assured that they will acquire validated information

The objective of this research is to develop an optimal inventory allocation methodology for a supply chain consisting of a capacitated retailer with limited shelf space, and two unreliable capacitated suppliers in an uncertain environment. We develop conceptual and analytical models that provide allocation preferences between shelf-space and warehouse in both deterministic and stochastic demand cases, and develop managerial insights based on them. For each case, we provide both a closed-form solution and a heuristic method, and illustrate the bounds on the optimal solution. Further, we show that the cost function is L-convex in some cases. Finally, we prove that the expected profit decreases as the variance of demand increases

La littérature met en avant le rôle des communautés de pratique (CoPs) dans la constitution et le partage de connaissances tacites et ancrées. Cependant, leur impact sur les processus d’innovation reste l’objet d’un débat. Nous nous attachons à mieux comprendre le rôle des CoPs dans l’innovation à l’échelle d’une firme multinationale. A partir de l’étude de cas approfondie d’une innovation développée au sein d’une filiale et déployée dans une autre, nous montrons le rôle critique de l’implication conjointe de deux CoPs de natures différentes, l’une pilotée et soutenue par le top management et l’autre autonome et spontanée. Nous spécifions les modes de coordination entre cesCoPs qui ont soutenu le développement et le déploiement de l’innovation dans la FMN

We study the pricing and capacity allocation problem of a service provider who serves two distinct customer classes. Customers in each class are inherently heterogeneous in their willingness to pay for service, but their utilities are also affected by the presence of other customers in the system. Specifically, customer utilities depend on how many customers are in the system at the time of service as well as who these other customers are. We find that if the service provider can price discriminate between customer classes, pricing out a class, i.e., operating an exclusive system, can sometimes be optimal and depends only on classes’ perceptions of each other. If the provider must charge a single price, an exclusive system is even more likely. We extend our analysis to a service provider who can prevent class interaction by allocating separate capacity segments to the two customer classes. Under price discrimination, allocating capacity is optimal if the “net appreciation” between classes, as defined in the paper, is negative. However, under a single-price policy, allocating capacity can be optimal even if this net appreciation is positive. We describe in detail how the nature of asymmetry in classes’ perception of each other determines the optimal strategy

In their attempt to define radically new product–market pairs, according to the literature, new technology ventures (NTV) are confronted with an apparent dilemma. On the one hand, they should delay key commitments to remain flexible in the face of high uncertainty. On the other hand, commitments are necessary to enable learning and progress. Based on the longitudinal study of four NTVs, we find that the entrepreneurs resolve this dilemma by (i) defining their product and market progressively through iteration and learning, and by (ii) basing this progressive definition on stakeholders’ commitments. We analyse this approach and label it “commit and learn”. Following an inductive methodology, we suggest a conceptual framework to enhance the understanding of commitment as a multi-dimensional concept for new ventures
