New product development. Elimination of wastage. Continuous improvement , etc. A very high emphasis on quality both for products & services has generated a new concept known as JUST- IN –TIME. JUST-IN-TIME/JIT is an approach which seeks to eliminate all sources of waste, anything which doesn’t add value in production activities, by providing the right part at the right place at the right time .

SEVEN WASTES : 

SEVEN WASTES JIT ALWAYS INSISTED ON ELIMINATION OF WASTES.SHIGCO SHINGO, A JAPANESE JIT AUTHORITY IDENTIFIES 7 WASTES. TO HIM BY ATTENDING TO THESE WASTE, THE IMPROVEMENT IS ACHIEVED. THOSE 7 KINDS OF WASTAGES ARE: Waste of stocks. Waste of waiting. Waste of processing. Waste of defective production. Waste of over production. Waste of motion. Waste of transportation.

STRIVES FOR REDUCED SET-UP TIMES & SMALL LOT SIZES. THERE SHOULD BE RELIABLE VENDORS, EMPLOYEE INVOLVEMENT & CO-OPERATION WITH TOTAL PRODUCTIVE MAINTENANCE. AS A CONCEPT JIT MEANS THAT, VIRTUALLY NO INVENTORIES ARE HELD AT ANY STAGE OF PRODUCTION AND THAT THE EXACT NUMBER OF UNITS ARE BROUGHT TO EACH SUCCESSIVE STAGES OF PRODUCTION AT THE RIGHT TIME. THAT’S WHY THE JIT CONCCEPT IS OTHERWISE KNOWN AS : ZIPS (ZERO INVENTORY PRODUCTION SYSTEM), ZIN (ZERO INVENTORIES), MAN ( MATERIALS AS NEEDED), NOT (NICK OF TIME).
