Conclusion and Discussion

Conclusion and Discussion Social Network Analysis was integrated in TraVis for a better understanding of project members' social environment consisting of socio-technical interrelations Better awareness of a project's communication channels for project leads by highlighting the connections among team members Increasing successful communication and collaboration of project workers by easily finding experts Outlook and further research : Improving GUI, e.g. in terms of adding more role-based views and alternative visualizations of socio-technical dependencies Trying to anticipate a user‘s navigation and enable intuitive navigation Platform independence by importing functionality

Social Network Analysis was integrated in TraVis for a better understanding of project members' social environment consisting of socio-technical interrelations

Better awareness of a project's communication channels for project leads by highlighting the connections among team members

Increasing successful communication and collaboration of project workers by easily finding experts

Outlook and further research :

Improving GUI, e.g. in terms of adding more role-based views and alternative visualizations of socio-technical dependencies

Trying to anticipate a user‘s navigation and enable intuitive navigation

Platform independence by importing functionality
