Q1. What is Cycle time
Ans. 
Cycle time is the total time taken to complete a process or task from start to finish.
• Cycle time is a key metric in process engineering to measure efficiency.

• It includes all the time spent on value-added and non-value-added activities.

• Cycle time can be calculated by dividing the total production time by the total number of units produced.

• For example, if a manufacturing process takes 10 hours to produce 100 units, the c

Q2. What is RPN
Ans. 
RPN stands for Risk Priority Number and is a calculation used in Failure Mode and Effects Analysis (FMEA) to prioritize potential failure modes.
• RPN is calculated by multiplying the severity, occurrence, and detection ratings of a potential failure mode.

• It helps prioritize which failure modes should be addressed first based on their potential impact and likelihood of occurrence.

• A higher RPN indicates a higher risk level
