Particulars of raw material, intermediate products and final product, process details, productqualityparameters.

Particulars of the manufacturing environment.

Human resource management.

Productivity analysis for various processes.

NOTE:• The students are supposed to complete at least three of the above mentionedassignments working inatleast three sections.

Students working in groups of 4 or 5 will have to cover 5 assignments.

• In case any student finds more than three sections available in the factory, thetime allocated forcarrying out the assignments in each section may be suitably adjusted to cover allthe sectionsavailable.

• The Project deliverables/results should be quantified as far as possible. Weightagewould be given to



the facts and statistics during evaluation of the report.

Students have to maintain learning dairy thought the duration of the Internship. &submit the same during the jury.
