	abstract = {Framework programs (FPs) are the main research policy tools of the European Union (EU), attracting substantial attention from policy-makers and scholars. Therefore, an increasing number of studies have investigated the EU’s FPs from various angles; however, very few studies address the effect of the complex nature of the concentration of resources and their implementation. While several studies have examined the concentrations of collaboration structures, much less attention has been given to institutions, especially the concentrations that appear during implementation. Institutions that have been awarded several projects at the same time are forced to share their resources between the running projects, which can make the implementation of the projects riskier and thus jeopardize the project’s outcome. Therefore, the role of project management, which must allocate resources among complex implementation structures, such as multiprojects and programs, across portfolios, is appreciated. The aim of this study was to analyze the progression of the nature of concentration, such as institutional concentration in the four most recent framework programs (FPs), namely, FP5, FP6, FP7, and Horizon 2020 (H2020), and the structural and implementation concentrations in the last two framework programs. The study employed the CORDIS database, which encompasses both institutional and project-related information derived from four distinct framework programs. The findings indicated that the parameters of the collaboration network exhibited minimal changes; however, the concentrations of institutions experienced significant alterations. The concentration of complex project structures increased along with institutional concentration, which in turn led to greater efficiency and productivity and, in this way, excellence. Hence, it can be inferred that the output-increasing effect of the program structure is undermined in the deployment of other implementation structures by the need to share resources among several projects running in parallel. The strategy of using parallel projects involves inherent hazards because of the finite nature of resources, which consists primarily of human talent in the form of researchers. The results currently support policy-makers in three ways: (1) an improved understanding of how implementation structures evolve in EU-funded Framework Programs; (2) strengthened linkages among institutional concentration, productivity and excellence; and (3) insights into the design of the EU FP ecosystem.},

	abstract = {Dynamic capability (DC) theories are widely used by innovation scholars, but there is little empirical work that applies these theories in ways that can be used by practitioners. Moreover, DC studies tend to suffer from tautological issues when measurements of DC overlap with those of firm performance. To fill this void, this paper explores how scholars can help companies in creating a dynamic capability. We adopt a design science approach in which scholars and practitioners team up to address and resolve a focal firm's (micro-DC) challenge in managing a large number of product development projects that run simultaneously but all depend on the same resource pool. To address this challenge, we design and implement a process technology tool. This study thus demonstrates how one can solve a real-life DC challenge by developing a practically relevant solution, based on design science.},

	abstract = {The control chart approach in industrial processes often faces significant challenges in accurately assessing the in-control (IC) and out-of-control (OC) performance of a process because of the limitations of conventional performance metrics. Traditional methods, such as the average run length (ARL)-based p-chart, may not effectively capture the complexities of run-length (RL) distributions, particularly in sectors with demanding performance standards. This study addresses these challenges by introducing a percentile-based (PB) p-chart approach, which guarantees specific IC and OC performance with predefined probabilities. The proposed approach overcomes the limitations of conventional methods, treating the ARL-based p-chart as a special case within the broader PB framework. By imposing constraints on the RL distribution, it is possible to guarantee predetermined probabilities for both IC and OC performance. This ensures that the IC run length ( RLIC ) exceeds the desired value, whereas the out-of-control run length ( RLOC ) remains below the desired threshold. The effectiveness of this p-chart scheme is shown through simulations and various numerical examples. The numerical results show that the p-chart based on the proposed scheme outperforms the existing methods and minimizes false alarms. To ease the computation of the optimization used in this design, software support of the proposed approach is provided for public use through a freely accessible R library pbcc. Finally, the implementation procedure of the proposed design is also demonstrated using two real-data examples. The numerical results show that the p-chart based on the proposed scheme outperforms existing methods, with a 150% improvement in the water bottle manufacturing process and a 45% improvement in the cardboard filling and packing process, while also minimizing false alarms.},
