Providing consultancy services and promoting Industry-Department interactions.

Enhancing the visibility of the Department through seminars, workshops and publications.

PROGRAMME EDUCATIONAL OBJECTIVES (PEOs)

PEO 1: Provide students with the fundamental technical knowledge and skills in workshop and production engineering to recognize, analyze and solve problems, and to apply these abilities to the generation of new knowledge, ideas or products in industry or government; and to implement these solutions in practice.
PEO 2: Provide students with the necessary instruction and practical experience to work well in local and international team environments and to be effective written and oral communicators, both for communicating ideas to other people, mentoring, and for learning from others.
PEO 3: Produce students who recognize the importance of and engage in life-long learning, whether through self-study, continuing education courses or workshops, or through formal graduate level education and encourage others to have this same motivation.
PEO 4: Produce students who have an understanding of ethical responsibility and service towards their peers, employers, and society and follow these precepts in their daily lives.
