PSW stands for Production Part Approval Process. It is a process used in manufacturing to ensure that a product meets the required specifications.

• The first stage is planning and preparation.

• The second stage is design and development.

• The third stage is validation and testing.

• The fourth stage is production and monitoring.

• The final stage is analysis and improvement.

• Examples of PSW documents include control plans, process

D5 & D6 are critical steps in 8D report for identifying root cause and implementing corrective actions.

• D5 involves identifying the root cause of the problem using tools like Fishbone diagram, 5 Whys, etc.

• D6 involves implementing corrective actions to prevent recurrence of the problem.

• Both D5 and D6 are crucial for ensuring long-term effectiveness of the corrective actions.

• Without proper identification of root cause (D5...read more

PFD stands for Process Flow Diagram while PFC stands for Process Flow Chart.

• PFD is a schematic representation of a process system showing the equipment, piping, and instrumentation.

• PFC is a graphical representation of a process system showing the sequence of steps involved in a process.

• PFD is used to understand the overall process flow and identify potential hazards.

• PFC is used to identify the steps involved in a proce...read more

Scatter diagram is a graphical tool used to display the relationship between two variables.

• It shows the correlation between two variables on a graph.

• It helps in identifying patterns and trends in data.

• It is useful in identifying the cause and effect relationship between two variables.
