    • A project buffer and resource management model in energy sector: A case study in construction of a wind farm project

      Zohrehvandi, Shakib; Vanhoucke, Mario; Khalilzadeh, Mohammad (International Journal of Energy Sector Management, 2020)
      Purpose This study aims to introduce an efficient project buffer and resource management (PBRM) model for project resource leveling and project buffer sizing and controlling of project buffer consumption of a wind power plant project to achieve a more realistic project duration. Design/methodology/approach The methodology of this research consists of three main phases. In the first phase of the research methodology, resource leveling is done in the project and resource conflicts of activities are identified. In the second phase, the project critical chain is determined, and the appropriate size of the project buffer is specified. In the third phase of the methodology, buffer consumption is controlled and monitored during the project implementation. After using the PBRM method, the results of this project were compared with those of the previous projects. Findings According to the obtained results, it can be concluded that using PBRM model in this wind turbine project construction, the project duration became 25 per cent shorter than the scheduled duration and also 29 per cent shorter than average duration of previous similar projects. Research limitations/implications One of the major problems with projects is that they are not completed according to schedule, and this creates time delays and losses in the implementation of projects. Today, as projects in the energy sector, especially renewable projects, are on the increase and also we are facing resource constraint in the implementation of projects, using scheduling techniques to minimize delays and obtain more realistic project duration is necessary. Practical implications This research was carried out in a wind farm project. In spite of the initial plan duration of 142 days and average duration of previous similar projects of 146 days, the project was completed in 113 days. Originality/value This paper introduces a practical project buffer and resource management model for project resource leveling, project buffer sizing and buffer consumption monitoring to reach a more realistic schedule in energy sector. This study adds to the literature by proposing the PBRM model in renewable energy sector.
    • Project recovery: Project failures and how to get rid of them

      De Bruyne, Marie-Julie; Moens, Eva; Vanhoucke, Mario (The Journal of Modern Project Management, 2021)
      Since the 1960s, project success has been receiving much interest from both academics and practitioners. Despite these efforts, project failure is still a recurring and prevalent phenomenon. In both peer-reviewed and non-peer-reviewed project management literature, a great deal of studies generates lists of success factors and failure causes. Few studies, however,investigate concrete recovery strategies to bring failing projects back on track. The present article, therefore, draws upon the literature on critical success factors and project recovery frameworks to construct an eight-step action plan that helps in recovering from project failure. The recovery action plan was awarded the University Contest by PMI Belgium in 2019.
    • Project regularity: Development and evaluation of a new project characteristic

      Batselier, Jordy; Vanhoucke, Mario (Journal of Systems Science and Systems Engineering, 2017)
      The ability to accurately characterize projects is essential to good project management. Therefore, a novel project characteristic is developed that reflects the value accrue within a project. This characteristic, called project regularity, is expressed in terms of the newly introduced regular/irregular-indicator RI. The widely accepted management system of earned value management (EVM) forms the basis for evaluation of the new characteristic. More concretely, the influence of project regularity on EVM forecasting accuracy is assessed, and is shown to be significant for both time and cost forecasting. Moreover, this effect appears to be stronger than that of the widely used characteristic of project seriality expressed by the serial/parallel-indicator SP. Therefore, project regularity could also be useful as an input parameter for project network generators. Furthermore, the introduction of project regularity can provide project managers with a more accurate indication of the time and cost forecasting accuracy that is to be expected for a certain project and, correspondingly, of how a project should be built up in order to obtain more reliable forecasts during project control.
    • Project schedule performance under general mode implementation disruptions

      Burgelman, Jeroen; Vanhoucke, Mario (European Journal of Operational Research, 2020)
      This paper presents a simulation study for a resource-constrained project scheduling problem with multiple alternatives. We decide on a set of baseline schedules at the project planning phase, resulting in options to switch between execution modes of activities during project execution. We assess the performance of the set of baseline schedules under general mode implementation disruptions. A simple, yet effective algorithm is presented to construct the set of baseline schedules. Moreover, a general disruption system is proposed to model different disruption types, disruption dependencies and disruption sizes.
    • Project team communication in financial service innovation

      Lievens, Annouk; Moenaert, Rudy (Journal of Management Studies, 2000)
      The role of communication during the innovation process of new financial services from an information processing perspective is examined. A contingency framework is developed on the role of communication and its impact on new financial services success. The relationship between project team communication and the reduction of innovative uncertainty on new financial service success is examined. The contingency model implies that managers have to recognize the critical communication roles that project members and frontline employees may fulfill. The communication flows mediated by these individuals foster the uncertainty reduction during the innovation process.

    • Promises from SOA: Reengineering a procurement process at Belgacom Mobile - a case study

      Van den Bergh, Joachim; Viaene, Stijn (International Journal of Business Process Integration and Management, 2012)
      The added value of this project, which contributes to the general understanding of SOA potential for BPM, lies in its innovative approach, whereby product and process are separated by means of production process ID creation. The redesign approach thus provides a sustainable answer to the ever shortening life cycle of products and technologies. In particular process practitioners will find value in reading the learning points from this paper.
    • The prospective value creation potential of blockchain in business models: A Delphi study

      Schlecht, Laura; Schneider, Sabrina; Buchwald, Arne (Technological Forecasting & Social Change, 2021)
      Blockchain technology is gaining awareness and drawing attention in corporate practice and academia. Both fields expect a fundamental impact of blockchain on business and society. However, since blockchain research within the business model context is still in a nascent stage, more in-depth insights is required of blockchain’s impact on firms’ value creation and value capture. This study builds on a Delphi approach and aims to identify the future value creation potential of blockchain for organizations by 2030. Based on expert interviews, workshop insights, and prior literature, we developed a meaningful set of 36 projections of blockchain implications for business models. Our findings, based on the elements of the PEST framework, predict massive efficiency gains through technological progress and promise complementary offerings through various novel combination possibilities, novel forms of collaboration and business model opportunities, and a dissipation of the significance of blockchain types. The combined use of blockchain solutions with other technologies is likely to serve as the basis for ecosystem developments. Our projected finding is that the internet of value will replace the internet of information by 2030. Thereby, our research contributes to technological forecasting and strategic planning by providing managers clear indications of blockchain developments and action recommendations.

    • Purchasing-driven sales: Matching sales strategies to the evolution of the purchasing function

      Paesbrugghe, Bert; Rangarajan, Deva; Sharma, Arun; Syam, Niladri; Jha, Subhash (Industrial Marketing Management, 2017)
      The personal selling field has witnessed the emergence of various sales strategies, including relationship, value, key account, and solution selling. Despite claims about their effectiveness, recent work challenges the relevance of existing sales strategies across buying contexts. Specifically, emerging sales strategies often focus on the user in the customer organization, without being explicitly aligned with the increasingly important purchasing function. To define the critical role of the purchasing function for sales effectiveness, this study collects data from 32 firms in two markets, their purchasing departments reveal four stages of purchasing evolution: passive (price focused), independent (cost-focused), supportive (solution/innovation focused), and integrative (strategy focused). The research demonstrates that each stage of purchasing evolution then requires distinct sales strategies by selling firms and any mismatch of purchasing evolution and sales strategy may be detrimental to sales. This novel view and the supported findings offers several implications for both research and practice.
    • Quality and pricing decisions in production/inventory systems

      Jalali, Hamed; Raïsa, Carmen; Van Nieuwenhuyse, Inneke; Boute, Robert (European Journal of Operational Research, 2019)
      In this article, we consider the impact of finite production capacity on the optimal quality and pricing decisions of a make-to-stock manufacturer. Products are differentiated along a quality index; depending on the price and quality levels of the products offered, customers decide to either buy a given product, or not to buy at all. We show that, assuming fixed exogenous lead times and normally distributed product demands, the optimal solution has a simple structure (this is referred to as the load-independent system). Using numerical experiments, we show that with limited production capacity (which implies load-dependent lead times) the manufacturer may have an incentive to limit the quality offered to customers, and to decrease market coverage, especially in settings where higher product quality leads to higher congestion in production. Our findings reveal that the simple solution assuming load-independent lead times is suboptimal, resulting in a profit loss; yet, this profit loss can be mitigated by constraining the system utilization when deciding on quality and price levels. Our results highlight the importance of the relationship between marketing decisions and load-dependent production lead times.
    • Quantile-based inference for tempered stable distributions

      Fabozzi, Frank; Fallahgoul, Hassan; Veredas, David (Computational Economics, 2019)
      If the closed-form formula for the probability density function is not available, implementing the maximum likelihood estimation is challenging. We introduce a simple, fast, and accurate way for the estimation of numerous distributions that belong to the class of tempered stable probability distributions. Estimation is based on the Method of Simulated Quantiles (Dominicy and Veredas (2013)). MSQ consists of matching empirical and theoretical functions of quantiles that are informative about the parameters of interest. In the Monte Carlo study we show that MSQ is significantly faster than Maximum Likelihood and the estimates are almost as precise as MLE. A Value at Risk study using 13 years of daily returns from 21 world-wide market indexes shows that MSQ estimates provide as good risk assessments as with MLE.
