Improvements Possible Eliminating intra-section transport of materials to be taken by vendors Direct movement of material by technicians to respective bins/crates based on suppliers Optimum utilisation of crate space. A proper method should be designed to fill the crates

Advantages Excessive material handling prevented Duplicate movement of material prevented Manpower can be saved More systematic and organized processes

Classification of materials Slow consumption material: Those material which are consumed at a very slow rate. They should be placed such that they don’t interfere in the working other materials Fast consumption material: Those material which are consumed at a very fast rate. Placed in matter such that they are easy to identify and issue. Change in layout of the kit section Improvement s
