The last co-worker or customer were not ready for Changes. Who is ready ? Nobody. Despite everybody would like to make improvements but in real life they rely on somebody else. Plant : figures of line efficiency and yield were not realistic (SLE was reported by 15-20% more then real; material yield -more 1-2% ). All reports were made by one person in his office. The changes were painful. Customer - waste user. I change the system of waste unloading from the plant. Before : after the night shift ( truck loading) 100m2 wear occupied with waste till noon. After : press for waste (paper,plastic bottles,...) were repaired and one qualified operator was appointed in the night shift. As a result - waste unloading time was declined from 4 hours to 30 min. GMP standard for this area has been implemented. I had met the customer ,he decreased his expenses and we became the friends. Great.
