1. What is Cycle Time?

Cycle Time (CT) is a key performance metric in time study and process analysis that represents the average time required to complete one cycle of an operation or process. It is calculated as the sum of all observed times divided by the number of observations.

2. How Does the Calculator Work?

The calculator uses the Cycle Time formula:

Where:

• \( CT \) — Cycle Time
• \( \sum OT \) — Sum of all observed times
• \( N \) — Number of observations

Explanation: The formula calculates the average time taken to complete a process cycle by dividing the total observed time by the number of cycles observed.

3. Importance of Cycle Time Calculation

Details: Cycle time analysis is crucial for process optimization, capacity planning, productivity measurement, and identifying bottlenecks in manufacturing and service processes.

4. Using the Calculator

Tips: Enter all observed time values separated by commas. The calculator will automatically sum the values and divide by the count to determine the average cycle time.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between cycle time and lead time?
A: Cycle time measures the actual work time, while lead time measures the total time from request to delivery including wait times.

Q2: How many observations are needed for accurate cycle time?
A: Typically 20-30 observations are recommended to account for normal variation in processes.

Q3: What time units should I use?
A: Use consistent time units (seconds, minutes, hours) for all observations. The result will be in the same units.

Q4: How can I reduce cycle time?
A: Identify and eliminate bottlenecks, streamline processes, reduce waste, and improve workflow efficiency.

Q5: When should I recalculate cycle time?
A: Recalculate after process changes, when introducing new equipment, or periodically to track performance trends.
