The understood necessity of an efficient information exchange between partners and tasks involved leads to the knowledge of suitable information exchange methods and tools. Process and product modeling techniques as a prerequisite for a successful information exchange can be applied by the students in specific exchange scenarios of ship product model data.

They will understand how the underlying design principles are implemented and will experience the complexity of naval architectural and ship design software systems. Students will learn how to operate in complex and unpredictable and/or specialized contexts, and will get an overview of the issues governing good practice.

This module is strictly linked to any course to be taken at URO. Depending on the topics of the selected course, a problem will have to be solved in a team. Students can select the course for the teamwork project according to their preference.

Learning outcomes of the course

Students will experience themselves in a team solving a defined problem in a defined time span. Depending on the course, the teamwork is linked to students that will intensively make use of different computer programs to solve the assigned task or will perform their own programming and experiments. While doing so, students will have a better understanding of the topics taught as they will work on a real world problem.

In teamwork students will develop to work effectively with a group as leader or member, they can clarify tasks and make appropriate use of the capacities of group members. They are able to negotiate and handle conflicts with confidence in a project in which the participants contribute with different but integrated software components.

Students will be able to demonstrate initiative and originality in problem solving, can act autonomously in planning and implementing tasks at a professional level while making decisions in complex and unpredictable situations. They will develop a comprehensive understanding of techniques and methodologies applicable to their own work.
