The final project workshop will accompany the students through the various stages of the final project:

During the second semester, the workshop will assist in a detailed definition of the nature of the project, the engineering challenge, the goals, objectives and metrics, alternatives for the execution of the project, initial design, building a work plan and defining the project's deliverables.

During the workshop they will learn the procedures, which include how to work independently and work with the project supervisor, milestones, assignments and grades.
