For in lean eliminating waste means we have a better process. What do we do in situations when we think we have removed all waste but the process is still not running smoothly. We now have a perfect process where we have removed all non value adding steps, but the process stops at certain points. For example, Peter has done his part and sent all the documents to Petra. However, Petra cannot start working on it because she has other things to do before that we still do not have the efficiency built in because the customer does not receive his document as fast as he cooked. When we talk about flow, we need to consider two major types of flow.
One is when we set up a road that will be processing goods until they amount to a certain number, or until a certain time of the day is reached. Let's say we decided that we'll distribute all stock at 5pm every day. This means that we wait until 5pm. Before we start work, on some days we'll struggle because we'll have a lot of stock to distribute. on other days we'll finish early note is not leveled properly, and our process is neither predictable nor stable. On the other hand, we have the single item flow where every item gets processed as soon as it is delivered.
This ensures there is little or no bottleneck and the load is manageable. This is also what lean calls a poor system. In the first case of batch processing, Think the workload is pushed on us? Well, in the second case, we are in control of the workload. The key of the pool system is that no one produces something before the next person is ready for it. This is activity on the concept of flow in lean.
You'll see a question on the screen. Read the question, then pause the session and take a moment to think When ready, press the play button. Is it good enough to eliminate the waste? By eliminating waste, we create a series of non value adding activities. But this is not enough. Why do we need to focus on the process flow?
The reason why we need to focus our attention on the process flow is Then we need to understand the principles that drive the flow. Lean advocates the principle, produce or deliver something that is requested and at a time when it is requested, not more than that
