A Management philosophy devoted to the proper arrangement and orderliness of the workplace. 5S lays the foundation for continuous improvement (Kaizen, Lean Manufacturing). A tool used to eliminate waste. (MUDA) 8 Waste Anything other than the minimum amount of equipment, materials, parts, space, and worker’s time which are “absolutely essential” in adding value to the product. Eight Deadly Wastes • Over Production • Transportation • Product Defects • Excess Motion • Inventory • Waiting • Excess Process • Under-utilizing People 1 9 Over Production Waiting Transportation Correction MUDA Unused Creativity Over Processing Motion Inventory 5S The Foundation for Everything “Good factories develop beginning with the 5Ss; bad factories fall apart beginning with the 5Ss.” —Hiroyuki Hirano, Chairman JIT Management Laboratory, Co., 5S The Foundation for Everything The underlining principal of 5S: A place for everything and everything in its place. 12 Management Support 5S starts from the top Without the support of: - Upper management - Middle management - Front line supervision YOU WILL SURELY FAIL !!!!!! 13 5S Sort Set In Order Shine Standardize 2S 1S 5S Sustain 3S 4S 14 Meaning of the 5S’s Sort Clearly distinguishing between what is necessary and what is unnecessary, while disposing of the latter. Evaluate all items in the workplace and determine which items are really needed. Understand why items are needed. Keep only what’s needed. Throw out what’s not needed. Include desk drawers and filing cabinets - 15 Sort Where? Walkways, Floors Storage shelves Cabinets Drawers, Desks Walls, Bulletin Boards Between Dock Doors Around poles On and around machines EVERYWHERE!!!!! What? Excess materials Tools, fixtures, gauges Spare parts Documents Brushes Cloths Furniture Seldom used equipment EVERYTHING!!!!! 16 Sort and JIT Corresponds to the Just-In-Time principle: Keep only what is needed. Only in the amounts needed. Only when it’s needed. Remove all items not needed for current production. 17 Sort – Problem Avoidance The plant becomes crowded and hard to work in. Cabinets, lockers and shelves required for unneeded items get in the way of communication and place unwanted walls between employees. Time is wasted searching for parts, tools and fixtures. Unneeded inventory and machinery are costly to maintain. Excess stock on hand hides problems on the production floor. Unneeded items and equipment make it harder to 18 improve the process flow. Sort 19 Sort 20 Meaning of the 5S’s Set In Order Organize the necessary items so that they can be used and returned easily. Sort first so we don’t waste time straightening things we don’t need. Organize all needed items - Locate items where they most needed. - Identify where to return items when not in use. - Identify items and their storage locations. Make the order of things clearly understood at first glance. Eliminate all wasted time and motion. 21 Set In Order Provide a convenient, orderly and safe place for everything…and keep it there! Set In Order 23 Set In Order Can we achieve requirements more simply? …incorporate tools Keep tools close to where they are needed Set In Order Make locations obvious 120 Label names and addresses 121 121 122 123 122 123 26 27 28 Marking Color Code Work Area - White Aisles - Yellow WIP - Blue Scrap/Non-Conforming - Red Finished Parts - Green 29 30 31 32 Meaning of the 5S’s Shine Clean floors, equipment, and furniture in all areas of the workplace. During and after the straightening process, the work place must be scrubbed. Make things clean , neat and orderly. - Sweeping floors. - Wiping off machinery, tools, computers and furniture. - Use the cleaning process to inspect for sources of dirt, oil, trash, etc. 33 Shine Monitor and restore the condition of equipment and the workplace during cleaning Meaning of the 5S’s Standardize Maintaining and improving the standards of the first three S’s The first three S’s have been done - Sort - Set In Order - Shine Maintain and improve the first three S’s. -Eliminate causes of dirt leaks and spills. -Create systems to keep things neat and organized. 35 Standardize Establish standards of cleanliness and procedures for routinely maintaining workplace condition Problems when Standardize is not implemented well Conditions go back to the old and undesirable levels At the end of the day piles of unneeded materials are left over. Tool storage areas become disorganized The purpose of Standardize is to prevent setbacks in the first three. To make implementing them a daily habit. 37 Standardize Everything Beyond the Cleaning Work methods Data processing Reports Cleaning Forms Training Tools 38 Meaning of the 5S’s Sustain Achieving the discipline or habit of properly maintaining the correct 5S procedure. Develop a habit of practicing the first four S’s Make 5S a way of life. 39 Definitions Sort - Clearly distinguishing between what’s necessary and what’s unnecessary, while disposing of the latter. Set In Order - Organize the necessary items so that they can be used and returned easily. Shine - Clean floors, equipment, and furniture in all areas of the workplace Standardize - Maintaining and improving the standards of the first three S’s Sustain - Achieving the discipline or habit for properly maintaining the correct 5S procedure. 40 Benefits of 5S’s How will we, as a group, benefit from 5S? Reduced Waste Improved Safety Easier Maintenance Higher Quality Improved Profitability 41 Benefits of 5S’s Con’t How will you, as an individual, benefit? You can take pride in a 5S workplace Your co-workers will respect you and your work space. You can also keep a positive mental attitude 5S CREATES A BETTER PLACE TO WORK 42 RED TAG STRATEGY Initiate first round of Red Tagging Select members from various areas Select a manager to lead the team First session should be plant wide Identify Red Tag Targets Inventory, equipment, supplies, tooling Office areas are not exempt from red tagging 43 RED TAG STRATEGY Hillman B.S.A. ARMSTRONG Sopwith Ltd.. RED TAG STRATEGY Define Red Tag criteria Determine what criteria will be used to distinguish a needed item from an unneeded item Example: Save only the items needed to make the next day, next week’s or next month’s production schedule. Make Red Tags Determine information to be recorded on tags Determine material to be used for red tags 45 RED TAG STRATEGY Conduct Red Tag Session Explain the red tag criteria to all teams Make sure you have a good cross-section of people tagging items in order to prevent the “I MIGHT NEED THAT” Syndrome Red tag the entire plant as rapidly as possible Evaluate the red tag items Review the material that has been tagged Dispose of the truly unnecessary inventory, equipment and other items Discard any material which is still tagged after a predetermined amount of time 46 All tags must be completed and returned RED TAGGING HINTS Record information about all tags used on a Red Tag Log where you can track disposition easily Make sure everyone understands what is to be tagged and why Discourage people from being defensive Be fair all areas get tagged Don’t compromise; IF IN DOUBT, THROW IT OUT! Necessary items can be tagged if improvements are known or suggested Do not put multiple tags on any one object Make reasonable allowances for decorative items such as plants or family photos 47 Forms 48 CELL/AREA TAG NUMBER RED TAG CATEGORY 1.
