The lean manufacturing term "pull," on the other hand, denotes a production process that begins from the other EnergyFirst end-the customer demand. Demand "pulls" the product along the production stream, thus reducing waste. The flow of resources in the process is regulated because there is now replacement of only what has been consumed and no more than is immediately deliverable. In this way, overproduction, resultant delays, and excess, resource-consuming inventory are avoided. And waste is eliminated or reduced.
An illustrative, though slightly over-simplified, analogy often used to illustrate the pull principle is that of a vending machine. The machine is stocked with snacks and sodas. Customers come along, put in their money, and make their selections. Later, the vending machine is restocked with only those items and in those amounts determined by customer demand. Consequently, there's never too much of anything taking up valuable space in the machine and possibly spoiling.
Now, "customer," within the context of lean manufacturing implementation in the pharmaceutical industry, means more than just the end user. It also encompasses downstream segments of the production process. The downstream "customer" demand pulls the product from the upstream segments, downstream activities signaling their needs to those upstream. This means, then, that there's not too much anything at any time and people aren't waiting. In the pharmaceutical industry, however, the difficulty arises in trying to adjust batch or blend sizes to accommodate the pull principle of lean manufacturing.
