RATIONALE
In present scenario, there is an urgent need to develop right kind of attitude, knowledge and
skills amongst the Diploma engineers leading them to achieve gainful wage/ self-employment.
There is a huge gap in perceptions of employers and employees regarding meeting the job
requirements. Also the dual challenges of competing in global working environment and
keeping pace with the rapid technological advancements call for re-design of curricula and
thus enabling the importance of generic and managerial skills. Entrepreneurship development
aim at developing conceptual understanding for setting up owns’ business/enterprise to cope
up with the problem of unemployment and also to promote the socio- economic development of
our country. Both the subject areas, “Basics of Management and entrepreneurship
development” are supplementary to each other. Knowledge and skills of these must be
imparted to diploma engineering students for enhancing their employability and confidence in
their personal and professional life.

 6.7 MAJOR PROJECT
L T P
- - 10
RATIONALE
The practical training cum project work is intended to place students for project oriented
practical training in actual work situations for the stipulated period with a view to:

i) Develop understanding regarding the size and scale of operations and nature of field
work in which students are going to play their role after completing the courses of
study.
ii) Develop understanding of subject based knowledge given in the class room in the
context of its application at work places.
iii) Develop first-hand experience and confidence amongst the students to enable them to use
and apply polytechnic/institute based knowledge and skills to solve practical problems in
the world of work.
iv) Develop special skills and abilities like interpersonal skills, communication skills,
attitudes and values.

This practical training cum project work should not be considered as merely conventional
industrial training in which students are sent at work places with minimal supervision. This
experience is required to be planned and supervised on regular basis by the polytechnic
faculty. For the fulfillment of above objectives, polytechnic may establish close linkage
with 8-10 relevant organization for providing such an experience. It is necessary that each
organization is visited well in advance and activities to be performed by students are
well defined. The chosen activities should be such which are of curricular interest to students
and of professional value to industrial/field organizations. Each teacher is expected to
supervise and guide 5-6 students.

Effort should be made to identify actual field problems as project work for the students. Project
selected should not be too complex which is beyond the level of the students. The
placement of the students for such a practical cum project work should match with the
competency profile of students and the project work assigned to them. Students may be
assessed both by industry and Polytechnic faculty. The suggested performance criteria is
given below:

1. Punctuality and regularity

2. Initiative in learning/working at site
3. Level/proficiency of practical skills acquired
4. Ability of solve live practical problems
5. Sense of responsibility
6. Self-expression/communication skills
7. Interpersonal skills/Human Relation
8. Report Writing Skills
9. Viva Voce

The projects given to students should be such for which someone is waiting for solution. Some
of the suggested project activities are given below:
1. Projects connected with repair and maintenance of machine
2. Claim Settlement of Accidental Vehicle
3. Body Fabrication
4. Projects related to quality control
5. Projects relating to erection, installation, calibration and testing
6. Setting up of a Garage
7. Overhauling and testing of Engine (using engine scanner)
8. Vehicle testing
9. Project work related to making small working models related to recent trends in
automobile industry
