Transcript of Case Study Final
Introduction Lakshmi Technology and Engineering Industries Limited (LTE), was incorporated on the 18th October 2004 and operations were initiated soon after its founding. The company is engaged in the manufacture of precision parts, realization of subassemblies and assemblies, integrated production of subsystems and main systems for various sectors such as the Aerospace, Defense, and for high-end technology oriented sectors. In a short span of 10 years LTE has evolved as a supplier of complete modules and subsystems by excelling the customer requirements for various critical components in high technology domains. Further LTE engages itself in the manufacture of critical products such as motors, control valves, sensors & fluid control components.
LTE aims at giving its customer complete satisfaction by achieving their requirements at the right time and in exact quality. LTE handles all aspects, right from the specification given by the customer to design/analysis and complete product realization and testing, making us a one stop solution for all our customers. We strive to further the relationship between our customers by developing dedicated resources for our customers to ensure the delivery and quality focus is maintained at all costs.
VISION: To innovate and provide superior products and services to enhance the value of human life. MISSION: Provide an environment, which propels every employee to innovate superior products and services adhering to ethical and moral values
