This thesis aims to analyze organizational change in a social network analysis perspective, exploiting longitudinal data collected after a modification of the organizational structure in an Italian Teaching Hospital The manuscript is organized into three papers. The first paper focuses on the theme of the relationship between formal networks and informal networks, analyzing how the modification of the first involves a corresponding variation in the second. The paper demonstrates how, in the absence of formalized organizational structures, individuals tend to establish new ties with colleagues who belong to the same specialization. The second paper, drawing purely from the organizational behavior literature, analyzes the issue of the network dynamics , providing evidence and antecedents for network stability in response to organizational change. Particular attention is also given to the intra - team dynamics and the impact of individual perception of collective properties in driving employees in accepting or not the organizational change.

La tesi ha l’obiettivo di analizzare il cambiamento organizzativo in una prospettiva di social network analysis, sfruttando dati longitudinali raccolti a seguito della modifica della struttura organizzativa in un Policlinico Universitario italiano. Il manoscritto è organizzativo in tre paper. Il primo paper si focalizza sul tema del rapporto tra network formali e network informali, analizzando come la modifica del primo comporti una corrispondente variazione nel secondo. Il paper dimostra come, in assenza di strutture organizzative ben formalizzate, gli individui tendono ad allacciare nuovi legami con colleghi che appartengono alla stessa specializzazione. Il secondo paper, invece, attingendo prettamente alla letteratura di comportamento organizzativo, analizza il tema della dinamicità del network, fornendo evidenze in relazione alla stabilità del network stesso a seguito del cambiamento. Particolare attenzione, è inoltre, dedicata alle dinamiche intra – team e al ruolo di quest’ultime nell’accettazione o meno del cambiamento. Infine, il terzo paper sviluppa il tema della network density e di come quest’ultima possa essere correlato al cambiamento organizzativo, in termini di reazione al cambiamento. Inoltre, si dimostra come la formalizzazione abbia un impatto positivo sulla densità del network, specie in contesti organizzativi caratterizzati da una bassa gerarchia e coordinamento orizzontale.

Abstract
This thesis aims to analyze organizational change in a social network analysis perspective, exploiting longitudinal data collected after a modification of the organizational structure in an Italian Teaching Hospital The manuscript is organized into three papers. The first paper focuses on the theme of the relationship between formal networks and informal networks, analyzing how the modification of the first involves a corresponding variation in the second. The paper demonstrates how, in the absence of formalized organizational structures, individuals tend to establish new ties with colleagues who belong to the same specialization. The second paper, drawing purely from the organizational behavior literature, analyzes the issue of the network dynamics , providing evidence and antecedents for network stability in response to organizational change. Particular attention is also given to the intra - team dynamics and the impact of individual perception of collective properties in driving employees in accepting or not the organizational change. Finally, the third paper develops the theme of network density and how the latter can be related to organizational change, in terms of reaction to change. Furthermore, it is shown how formalization has a positive impact on network density, especially in organizational contexts characterized by a low hierarchy and horizontal coordination.File | Dimensione | Formato | |
