PRESENTED BY – KRISHNA HEDAFinding the WasteThe 8 Waste
What is Value?A measurement of the worth of a product, or service, by a customer based on it’s usefulness in satisfying a customer needAn activity, process or operation that changes the product from one form to another in order to get it closer to the customer’s specificationsIt is something that the customer is willing to pay for
What is Waste?Any activity that adds costs or time but does not add valueConsuming more resources (time, money, space, etc) than are necessary to produce the goods, or services, that the customer wantsPure Waste: Actions that could be stopped without effecting the customer Incidental Waste: Actions that need to be done based on how the current system operates but do not add value
The 8 Types of WasteOverproduction
Inventory
Transportation
Motion (Operations)
Processing
Defects / Quality
Waiting
People’s SkillsOverproductionSupplying the process with more than is needed to meet order requirements, sooner and faster than it is needed, causes almost all other types of wasteThis is the worst waste of all, because it helps cause all the othersCommon causes:Producing more than is required to make up for yield lossScheduling production to forecasted demandLong changeovers or avoiding changeovers lead to large lot production
InventoryRequires people, processes and time to count, Process, execute, store and maintain itIf we do not get orders the items processed will not be useful and would be waste of time and effort.Inventory is often used to help hide other wastesCommon causes:Overproduction/ over processingLong changeover times b/ween processesDefective, or questionable itemsMismatched production speeds

TransportationDouble or triple handling, of documents.It adds no value and is often used to get the extra inventory out of the way Common causes:Extra InventoryRetention points before and after operationsExcessive distance between operations (layout)Single skill focused operations
Motion (Operators)Walking without working (away from workstation) Searching for documents, tools, materials or informationReaching, bending or unnecessary motion due to poor housekeeping or workplace layoutProcess is not designed with employees in mindCommon causes:Poor workstation layoutIsolated operationsShared toolsFatigueWorkstation congestion
ProcessingDoing more than is necessary to produce an effectively outputExtra setup steps, over-specification of the process, extra processing stepsCommon causes:Lack of standard work or processesEquipment over designedProcess not updated with technology changesLack of effective problem solving
Defects / QualityDefective or DefectsCost of inspecting defectsResponding to customer complaintsRework or re-inspection of questionable matterCommon causes:Emphasis on downstream inspection; questionable matter passed onLack of standard workInfo/docs handling (transportation)Process design/Procedures

People’s SkillsEmployees are seen as a source of labor only, not seen as true process expertsPeople are told what to do, and asked not to thinkEmployees are not involved in finding solutions, opportunities to improve our process are missedCommon causes:Management does not involve employees in problem solvingNarrowly defined jobs and expectationsOld school management, worker relationships
How Does Waste Get There? Forget to change solutions when we change the processFail to understand why we do something a certain way, so we continue doing that way even if the limitation has been removedBuild it into our processesRoot cause of problems is not addressed or a band aid solution is implemented

    How Can WeFind It? Find the value added work, everything else is wasteGo out there and see itObserve our processes as if you do not know itTalk to the operators so you can understand why we do things the way we doWhat is the operation about? Why is it necessary?

    How Can WeFind It? Introduce itImplement one piece flow into the process and waste will rise to the surfaceHave the right attitudeWaste is hard enough to find when you want to find it, if we don’t want to find waste it will be impossible to root it out and remove it
