Students are divided up into small groups to develop (analyze, specify, design, program, and document) a real-world software application with a client organization coming from the local market. The aim of the course is to gain experience in the various phases of software development and in different aspects of group working. Special attention is given to Project Management activities, such as scheduling, time and resource management, production of reports and deliverables, etc. The group develops abilities to "pick up" and use new development tools and environments without formal training. The final product is a fully operational software system which is installed at the client site with execution of professional user acceptance testing and appropriate training.

Το μάθημα εστιάζεται στον σχεδιασμό και χρονικό προγραμματισμό έργων με έμφαση στα έργα πληροφορικής. Οι φοιτητές διδάσκονται τις μεθοδολογίες, τις τεχνικές και τα αναγκαία εργαλεία για αποτελεσματική και αξιόπιστη διαχείριση έργων γενικά, αλλά και της διαχείρισης έργων πληροφορικής, ειδικότερα. Έμφαση δίδεται επίσης σε προηγμένα θέματα που αφορούν τη διαχείριση έργων με περιορισμούς πόρων. Η κρισιμότητα των περιορισμένων πόρων σε ένα έργο συζητείται διεξοδικά και αναλύεται τόσο πρακτικά όσο και θεωρητικά υπό την οπτική των επιστημονικών πεδίων της επιχειρησιακής έρευνας και της συνδυαστικής βελτιστοποίησης.
