A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
It is used when observing a physical process, to record actions as they happen, and thus get an accurate description of the process. It is used when analyzing the steps in a process, to help identify and eliminate waste—thus, it is a tool for efficiency planning. It is used when the process is mostly sequential, containing few decisions.
P&IDs are originally drawn up at the design stage from a combination of process flow sheet data, the mechanical process equipment design, and the instrumentation engineering design. During the design stage, the diagram also provides the basis for the development of system control schemes, allowing for further safety and operational ...
If this part is replaced hundreds of times per year, over the course of many years, then there may be an opportunity to save money by adjusting the repair process to leverage this economy of scale (reliability improvements, component repair, etc.). This analysis drives the maintenance support for each repairable unit analyzed.
SCOR is a process reference model designed for effective communication among supply chain partners. As an industry standard, it also facilitates inter- and intra- supply chain collaboration and horizontal process integration by explaining the relationships between processes (i.e., Plan-Source, Plan-Make, etc.).

In the PCB design process, DFM leads to a set of design guidelines that attempt to ensure manufacturability. By doing so, probable production problems may be addressed during the design stage. Ideally, DFM guidelines take into account the processes and capabilities of the manufacturing industry. Therefore, DFM is constantly evolving.
Some benefits of an automotive TSB are that by widely circulating among dealership service departments and mechanics an engineering-level description and solution for a problem common to type, year, make or model of car, a well-managed TSB process can save technicians troubleshooting time; provide organized, itemized repair procedures; and ...
