4 Organization Overview At the beginning of the semester, students will build teams of 4 members. During the semester, each team will be responsible for: Planning and designing an empirical evaluation of a software technology Taking part in an empirical evaluation of a software technology Analyzing empirical data Presenting and documenting their results The planning and design of an empirical evaluation (along with the submission of the corresponding reports) during the semester time is mandatory for being allowed to take the exam.
