Transversal skills

• Assess progress against the plan, and adapt the plan as appropriate.
• Write a scientific or technical report.
• Set objectives and design an action plan to reach those objectives.
• Use a work methodology appropriate to the task.
• Communicate effectively, being understood, including across different languages and cultures.
• Access and evaluate appropriate sources of information.
• Make an oral presentation.
• Design and present a poster.

Teaching methods

The course is organised as theoretical sessions and the resolution of a real case study to be realised by a team.

Expected student activities

• Active participation to the lecture
• Project realisation as a team work

Assessment methods

An oral exam will concern the theory and its application in the case study.
