    • Identifying digital transformation paradoxes: A design perspective

      Danneels, Lieselot; Viaene, Stijn (Business & Information Systems Engineering, 2022)
      In turbulent contexts, organizations face contradictory challenges which give rise to management tensions and paradoxes. Digital transformation is one such context where the disruptive potential of digital technologies demands radical responses from existing organizations. While prior research has recognized the importance of coping with organizational paradoxes, little is known about how to identify them. Although it may be apparent in some settings which paradoxes are at play, other more ambivalent contexts require explicit identification. This study takes a design perspective to identify the relevant paradoxes in a digital transformation context. It presents the results of a 2-year action design research study in collaboration with an organization that chose to explicitly focus on paradoxical tensions for managing its digital transformation. The study's main contribution is twofold: (1) it presents design knowledge to identify organizational paradoxes; (2) it provides a better understanding of the organizational paradoxes involved in digital transformation. The design knowledge will help others to identify paradoxes when working with an organization and highlights dynamic and collaborative aspects of the identification process. The study also enhances the descriptive understanding of digital transformation paradoxes by showing the importance of learning and belonging tensions and by expressing a different view on what knowledge about paradoxes is, and how it is created and used.
    • Identifying influencers in a social network: the value of real referral data

      Roelens, Iris; Baecke, Philippe; Benoit, Dries F. (Decision Support Systems, 2016)
      Individuals influence each other through social interactions and marketers aim to leverage this interpersonal influence to attract new customers. It still remains a challenge to identify those customers in a social network that have the most influence on their social connections. A common approach to the influence maximization problem is to simulate influence cascades through the network based on the existence of links in the network using diffusion models. Our study contributes to the literature by evaluating these principles using real-life referral behaviour data. A new ranking metric, called Referral Rank, is introduced that builds on the game theoretic concept of the Shapley value for assigning each individual in the network a value that reflects the likelihood of referring new customers. We also explore whether these methods can be further improved by looking beyond the one-hop neighbourhood of the influencers. Experiments on a large telecommunication data set and referral data set demonstrate that using traditional simulation based methods to identify influencers in a social network can lead to suboptimal decisions as the results overestimate actual referral cascades. We also find that looking at the influence of the two-hop neighbours of the customers improves the influence spread and product adoption. Our findings suggest that companies can take two actions to improve their decision support system for identifying influential customers: (1) improve the data by incorporating data that reflects the actual referral behaviour of the customers or (2) extend the method by looking at the influence of the connections in the two-hop neighbourhood of the customers.
    • Imitation of management practices In supply networks: Relational and environmental effects

      Reusen, Evelien; Stouthuysen, Kristof; Roodhooft, Filip; Van den Abbeele, Alexandra; Slabbinck, Hendrik (Journal of Supply Chain Management, 2020)
      This study investigates the imitative use of management practices across a multitier supply network. Although imitation may take the form of any management practice, operationally, we focus on whether the buyer's control practices used with first‐tier suppliers results in similar control practices being used by these first‐tier suppliers with the second‐tier suppliers. Drawing on institutional theory, we identify relational context (i.e., affective commitment) and environmental context (i.e., environmental uncertainty) as two important factors influencing the extent to which such imitation takes place. Using unique survey data of vertically linked supply chain triads, we generally find support for the occurrence of imitation and more so in cases of high affective commitment. The results regarding environmental uncertainty further reveal selectivity in imitative behavior, calling attention to the level of deliberateness in imitation decisions in supply networks. Besides contributing to theory on imitative behaviors in the supply chain, this study also generates practical implications on the spread of management practices across multiple tiers.
    • The impact of a limited budget on the corrective action taking process

      Song, Jie; Martens, Annelies; Vanhoucke, Mario (European Journal of Operational Research, 2020)
      The main goal of project control is to identify the deviations between the baseline schedule and the actual progress of the project by measuring the project performance in progress and using the project control methodologies to generate warning signals that act as triggers for corrective actions to bring the project back on track. To that purpose, tolerance limits are set on the required project performance, such that if the warning signals exceed these limits, they should result in appropriate corrective actions. In this paper, the Earned Value Management (EVM) control method and its extensions are used to test their abilities in taking corrective actions under a budget constraint. More precisely, four different approaches are proposed for allocating the limited budget along the different project phases, and whether a proper allocation of the budget results in an increase of the expected project outcome is measured. A large computational experiment is conducted on a set of artificial projects to assess the efficiency and effectiveness of the budget allocation models. Results show that simply allocating budget according to the time accrue of projects performs better than methods that take cost, time/cost or risk information into account. Moreover, results indicate that allocating a budget that increases in later stages of the project is beneficial for the outcome.
    • The impact of applying effort to reduce activity variability on the project time and cost performance

      Martens, Annelies; Vanhoucke, Mario (European Journal of Operational Research, 2019)
      During project execution, deviations from the baseline schedule are inevitable due to the presence of uncertainty and variability. To assure successful project completion, the project’s progress should be monitored and corrective actions should be taken to get the project back on track. This paper presents an integrated project control procedure for measuring the project’s progress and taking corrective actions when necessary. We apply corrective actions that reduce the activity variability to improve the project outcome. Therefore, we quantify the relation between the applied managerial effort and the reduction in activity variability. Moreover, we define three distinct control strategies to take corrective actions on activities, i.e. an interventive strategy, a preventive strategy and a hybrid strategy. A computational experiment is conducted to evaluate the performance of these strategies. The results of this experiment show that different strategies are preferred depending on the topological network structure of projects. More specifically, the interventive strategy and hybrid strategy are preferred for parallel projects, while the preventive strategy is preferred for serial projects.

    • The impact of control on the discount for lack of marketability

      Van den Cruijce, Johan (Tax Notes International, 2022)
      Valuations of private companies can be required for tax purposes, merger and acquisition transactions, divorce settlements, partnership restructurings, etc. Very often, these valuations take place in litigious circumstances. The process for valuing private companies is deceptively complex. This is notably because there is no consensus on the size and determinants of two important valuation discounts that may need to be applied: the discount for lack of control (DLOC) and the discount for lack of marketability (DLOM). We have constructed a unique dataset based on court decisions that decide on a DLOM and identify its determinants. Ultimately, this dataset has allowed us to examine whether the level of control attached to the valuation subject has a significant effect on the DLOM. This paper finds that control, while normally attributed solely to the DLOC, also impacts marketability. This hitherto overlooked determinant has a statistically significant impact of 8% on the DLOM. Contrary to conventional wisdom, control applies not once but twice to a private company’s value: as the primary driver of the DLOC and again as a key determinant of the DLOM.

    • The impact of internal corporate social responsibility on organizational commitment: evidence from Vietnamese service firms

      Thang, Nguyen Ngoc; Fassin, Yves (Journal of Asia-Pacific Business, 2017)
      This study examines the relationship between internal corporate social responsibility (CSR) and organizational commitment in the service sector in Vietnam. Results from a survey of 256 employees indicate that internal CSR has a positive and significant correlation with organizational commitment. More specifically, labor relations, health and safety, and training and education had a significant effect on organizational commitment whereas work–life balance and social dialogue have no significant association with organizational commitment. The authors also provide implications, limitations, and recommendations for future research.
    • Impact of lean production on perceived job autonomy and job satisfaction: an experimental study

      Rodriguez, Denise; Buyens, Dirk; Van Landeghem, Hendrik; Lasio, Virginia (Human Factors and Ergonomics in Manufacturing & Service Industries, 2016)
      Previous studies have indicated positive and negative effects of lean production on employees' perceived work characteristics and job attitudes. The most detrimental consequence of lean production is a decrease in the perceived job autonomy of workshop employees. To reduce these negative consequences, we propose human resource practices for integration with lean production. Drawing on the job characteristics model, we hypothesized that the implementation of lean production combined with human resource practices would enhance perceived job autonomy, job satisfaction, and operational performance. To evaluate our hypotheses, we used an experimental design consisting of a simulation game that mimics a manufacturing company. We implemented lean production combined with human resource practices in this simulated company. The results indicated a significant increase in perceived job autonomy, job satisfaction, and operational performance. Moreover, the results revealed a positive relationship between job satisfaction and operational performance.
    • Impact of nested inventory allocation policies in a newsvendor setting

      Samii, Behzad (International Journal of Production Economics, 2016)
      We model an inventory management setting in which the decision maker first uses newsvendor model to decide on the amount of ordered perishable inventory for a fixed consumption period, based on the best available forecast of demand at the time of ordering. After a relatively long lead time, the consumption period starts and she has to assign the received inventory to two priority customer classes given the -newly updated- rate of arrival of each class. The assignment of inventory requires two simultaneous decisions: 1) the reservation quantity for the high priority class and 2) the choice of inventory allocation mechanism (Standard Nesting SN or Theft Nesting TN), to minimize the expected units short of the high priority class while minimizing the wasted inventory at the end of the fixed consumption period. We assume that some partial information about the bottom line impact of a shortage in high priority customer class compared to the other can be conjectured. For both inventory allocation mechanisms, we then calculate the monetary benefit for all feasible reserved quantities to identify the optimal reserved quantity. We derive closed form expressions for the expected number of units short in each demand class under SN and TN allocation mechanisms. We showcase the management of electricity smart meter inventory in a multi-year implementation project consisting of multiple fixed consumption periods. Numerical experiments and graphical interpretations feature the optimum allocation policy and the cost minimizing reserved quantity under such policy.
