The 7 Wastes in Detail- TIM WOOD!   The 7 wastes are Non Value Added and must be seen as the enemy.   They absorb time, and cost.   The way to remember them is to think of Tim Wood. This guy is in every business, and it is your responsibility to hunt him down and reduce and eliminate as best you can. He absorbs costs, overheads, and cash in the business.   So here is TIM WOOD!   T – Transport I – Inventory M – Movement W – Waiting and delays O – Over production O – Over Processing D – Defects   Transport Transportation of product and work in progress is necessary, but it must be controlled in terms of times and distance. Each turn a product is moved, it stands the risk of being damaged, lost, delayed, and so on. More critically, the longer a product moves around, the longer there is no Value being added to it, as it is not being physically transformed. Transportation does not make any transformation to the product that the consumer is supposed to pay for.   Inventory Producing something to sit around and wait for the next process, which doesn't start straight away is NVA. The product is waiting and not adding value sitting on a job rack somewhere. The problem is, the more inventory the worse it is, as this can be in the form of Work in progress, raw material or finished goods.   The point is: in any of these three forms of inventory, if it hasn't been sold, it is cash that has been tied up into the material, which the customer hasn't bought yet– These result in a massive drain on the cash flow!   Movement Similar to transportation, but movement refers to movement of operator and equipment. Again, think of the fact that operators moving around, searching and finding things cannot be adding value. Same too with equipment – if you are spending time lumping equipment around, you cannot be using it to add value and make money, plus the chances of damage increases.   Waiting and Delays When work in progress and goods are not being worked on, they sit there waiting – waiting for the next process. This is typical of traditional 'Batch and Queue' methods. Waiting means that product is costing the company money and not adding value.   Over production The worst of the 7 wastes – as it incorporates all the other wastes as well. Over production appears when processes are not efficient. If Changeovers are too slow, one would over produce; if quality if poor, again, one would over produce, just in case. The problem is, "the customer may want 10 parts, for instance, but we will produce 20 parts and store them……."   The difficulty is that valuable time and energy has gone into producing parts that are sitting around consuming space in stores, whereby someone has to spend time processing them and stock counting, and the customer hasn't even bought them – All at a cost to the company!   Over processing If you don't know exactly what the customer wants, how can you align your processes to what the customer needs? Over processing is about completing work for the customer, which is more than the customer really wants. Think of mowing your lawn – would you cut each blade of grass with a pair of scissors and then measure it with a rule? Of course not -Mowing the lawn with the mower is sufficient.   Another example – A company i used to work for used to print mobile phone key pads. The customer wanted blemish free (looking at it with the naked eye) key pads, but our inspectors would view each part with an eye glass of 14 times magnification! Any slight imperfection in an eyeglass meant that the part was rejected, when in fact in clear light and with the naked eye, they were perfect!   It probably comes as no surprise that the company were wasting time in rework, over inspection, and rejects alone were over £500,000 per year on a product that turned over £3million per year!   Defects You can't add value twice! If you scrap a complete job, you wouldn't go to your customer and ask for an extra £5000 (or what ever the cost is!) to reprocess a job that you couldn't do right first time! Your customer would think you are mad and go elsewhere!   Every bit of scrap costs money and time – Money for the resource to pay staff, lighting, etc to do it again, but also means that you have to push another planned job back in the queue in order to get the rework out! It's all cost and less cash for the business.
