Abstract. Product design projects involve multiple team members with various knowledge and competencies that have to evolve with time, due to rapid organizational, technological and marketing changes. Project managers require management methods to optimize the assignment of tasks to human resources according to their competency levels and the need for competency evolution. In this paper, we tackle this optimization problem in the context of multiple design projects and multiple periods. The model we propose seeks to minimize two function objectives: (i) minimize the supplementary salary cost due to the extended task duration when using under-competent employees and (ii) minimize the financial penalties when the competency goals have not been reached. This problem has been solved by means of a simulated annealing -based optimization algorithm.
This research aims to develop a new team building method based on competency modelling in the field of project management. This method is divided into three main stages. First, a competency matrix based on a task-actor compatibility indicator helps to characterise the competency levels. Second, we apply a clustering algorithm in order to reduce the problem complexity and favour the employees' expertise. The clustering algorithm will decompose large sets of tasks and actors into smaller task groups related to different actor groups. It facilitates the project leaders to organise the actors into teams. Finally, the proposed task assignment model incorporates a learning curve in order to take the competency dynamics into account. Our computational experiments suggest that incorporating a clustering algorithm as a step of the method results in preserving expertise and thus helps project managers to find better tradeoffs between project cost (short term goal) and competency dynamics (long term goal).
Designing in an industrial context is a very complex activity. It needs the integration of heterogeneous knowledge or skills, to transform a set of ill-defined requirements into an artefact that satisfies esthetical, functional, technical, economical criteria. Design process optimization with methods like system engineering and core competency building are key issues for managers of product development process, design skills networks, communities of design practices… In the literature, these issues have been dealt with separately. In this paper, we propose a framework of reference that helps us to explicit the content of the core design competency. This framework is a first step beyond an efficient competency based management of design structures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
