Eight types of waste
Reasons why the waste occurs
|1.Over-production: Building batches of products larger than the customers’ immediate need.||This waste typically occurs because we want to increase utilisation of large and important machines, are worried about rejects and absenteeism so we produce more to be on the safe side. In just-in time systems being ahead of the production schedule is regarded as worse than being behind it.|
|2, Waiting: Production operators waiting because a machine has gone down, or a component is not available. Or when the operators are simply monitoring the machine as it does its value adding task.||Whilst operators being idle is easy to measure, it is more difficult when they are looking busy. In one example in a German automotive manufacturer, the set-up time in the press shop was reduced from 10 hours a week to 3.5 hours.|
|3. Transportation: Moving materials around the factory. Any process that is physically distant from the main line should be incorporated into the line if possible.||Masaaki Imai points out a common sign of a problem with layout is the need for conveyor belts. He goes on to say, “The best thing a company can do with its conveyor belts is to sell it to their competition, or send it to them free of charge.”|
|4. Extra processing: Processes that appear productive but are unimportant to the customer. Value stream accounting provides good guidance here. Do not include any costs and activities that do not add value to the customer.
|There are many ways an organisation can have extra processing.
|5. Excess inventory: Having materials, components, work-in-process, and finished goods levels above the immediate need.||When an inventory level is high nobody gets serious enough to deal with problems like quality, machine downtime, and absenteeism, and thus an opportunity for Kaizen is lost.
Also, with generally accepted accounting principles all finished goods carry prior months’ overheads into the future periods these goods were sold. Carrying forward costs to future periods leads to additional costs hitting the P/L when inventory levels fall.
|6. Waste of motion: Any motion of a person ‘s body not directly related to adding value is unproductive. While very evident in manufacturing environments it is of equal importance in all other environments.
|I recently witnessed a classic waste of motion activity in a hospital. I was in the the emergency department of Wellington’s largest hospital and my wife was having her blood pressure read. Because my wife’s records could not be brought into the room the nurse, who was wearing protective gloves, had to write the temperature down on a scrap of paper and then transfer it to the file when she returned to her work station.
There are many ways an organisation can have a waste of motion
|7.Waste due to rework and scraped rejects: Rejects interrupt production and require expensive rework (processing again to correct faults) or have to be discarded.||Reports that have to be rewritten are effectively rework.|
|8. Unused employee creativity: Employee ideas having to hurdle many obstacles before adoption and therefore not being raised.||Based on Toyota, we would need to have 10 innovations implemented per team member per year before we could say there is no waste in this area.|
While some of these types of waste, appear at first sight, to only be relevant to manufacturing you can apply many of them into other sectors. Since, as Dr Jeffrey Liker points out, “Most business process are 90% waste and 10% value-added work” there is a lot of scope in this area.
