Using YED software to visualize and analyze project management knowledge systems data

Abstract

The article proposes to consider some conclusions about the significance of a number of elements of the model of individual competencies of project managers proposed by the International Project Management Association (IPMA ICB 4.0) when presented as a directed graph. It is proposed to consider elements of the competency model (a set of 28 elements for the ICB model for project management) as the vertices of such a graph. It is proposed to carry out a structural analysis of such a graph using various combinations of representations that combine the "centrality" parameter and "weight characteristics" for the vertices of such a graph based on information about the number of edges adjacent to the vertices. The article demonstrates the approach proposed by the authors to the analysis of a directed graph using software such as the openly distributed product yEd, which has sufficiently wide capabilities for visualizing various systems modeled with its help, including graphs. It is also proposed to consider, as an example of using such a representation, a variant of transforming the existing IPMA ICB 4.0 model based on the representations for this structure obtained during the visual analysis using the yEd service. The structure of the general communication system IPMA ICB 4.0 is clearly demonstrated, and the presentation of each of the blocks of elements of this model is also visualized. Shows the role of the element "Leadership" as an "integral element", directly through which communication is carried out between all blocks of the model of elements. The role of such an element as "Power and Interest" in the analysis of a directed graph using a set of representations is also highlighted, which demonstrates the structural relationships of the entire system of elements of the system under consideration using the "centrality" property.
