Respect lean principle

Speaking abstractly, this fifth principle gives the basic principles of Lean Management a circle structure, which means that there will always be potential waste that may be identified and eliminated by the cycling use of the presented Lean-Management principles. Moreover, several Kaizen fundamentals have been specified to identify potential improvements, such as 3 Mu Muda, concretion of seven kinds of waste Muri, overwork of employees or machines respectively and Mura, unevenness considering production processes. Moreover, 5 5 is an approach to improve workplaces continuously in five steps. Finally, Poka-yoke is a systematic detection and prevention of mistakes. 

Standards are the baseline from which all continuous improvement activities can be measured. An example I often use is that of an order picker in a Toyota distribution center. I am not sure if the facts I use are correct, but that is inconsequential because what is important is the concept. Standard work for order pickers is 12 picks every 15 minutes. If in any 15-minute period they do not make their standard, they have to signal their supervisor. The supervisor immediately responds and approaches the order picker not to ask why he did not work to standard, but instead to ask what process problem, or problems, prevented him from making standard. Was the inventory count incorrect Was the inventory in the wrong location These and other questions will be asked until the problem is solved. This short, simple example demonstrates three distinct principles of lean respect for people, standard work, and a continuous improvement culture. Having defined standards that everyone understands enables the other two principles. Unlike this example, the actual workday of many supervisors is one spent firefighting rather than focusing on continual Improvement. Moving from one problem to the next fills their days because standards are unknown or not communicated. 

In principle, we can also envision that only the director h is tilted with respect to the layer normal k. Successive smectic layers can be either ferroelectric (with the same direction of polar order) or antiferroelectric (with opposite directions). Likewise, successive layers can be either synclinic (with the same direction of molecular tilt) or anticlinic (with opposite tilt directions).Those situations are illustrated in the bottom row of Figure 2-3. To distinguish from the tilt of the molecular plane (which is denoted by the symbol C to express clinic ), the tilt of the long axis will be called leaning and will be labeled with L. Just as in the SmCP cases we can have four distinct sub-phases SmL P, SmL P, SmL P and SmLgP depending on the subsequent tilt and polarization direction combinations. In such phases the polar axis is not parallel to the smectic layers and they have Cg symmetry.
