  4. 4. Southeast University Role of industrial engineering department in apparel industry: Importance of industrial engineering (IE) tools that can be used to improve upon the productivity and thus enhance the profits. Very few companies have been operating with a full fledged industrial engineering department and even those which boast of as an industrial engineering department(IED) are not allowing freedom and scope to function to its full capabilities. The role of IED is important for the garments industry for the following two reasons: It’s highly labor –intensive industry.  Effective planning is emerging as one of the key factors for the garments manufacturing industry. 4
