Procedure: Takt Time Calculation Sheet 1. Part No. - Record the appropriate part number that is being used for the calculation. 2. Operating Time - The number of hours in a shift times 60 minutes equals the total available operating time. Minus any breaks or cleanup time or any other activities that take place daily. This number equals the Operating Time. (Do not take out setup time ) 3. Daily Operating Time - The daily operating time is the time available to work in seconds per the number of shifts available to work. 4. Monthly Requirements per Production Plan - This number should be provided to you by scheduling, sales or forecasting to give you an accurate number. Be sure to look at 12 months to understand seasonality.

Procedure: Takt Time Calculation Sheet (Continued) 5. Number of Working Days in a Month - This is the number of days available to work in a month. Obtain this number from accounting. Make sure to get number of days for all 12 months to be able to calculate takt time for 12 months. 6. Daily Requirement - Monthly Requirements divided by Number of working days equals the daily requirement. 7. Takt Time Calculation - Takt time is calculated by number of shifts available. Daily Operating time divided by daily requirement equals takt time. Calculate takt time for the number of shifts available.

The observer will continue this procedure for at least 10 to 12 complete cycle repetitions. 10. Elapsed Time: Upon completion of 10 to 12 observations of the complete process cycle, it will be necessary to calculate the specific elapsed times for each process step. To calculate the actual elapsed time for any given element (step), subtract the clock running time of the following element from the desired element clock running time. Example: for element #1, 9a minus 9 equals 10. Procedure: Time Observation Sheet

1. Header Information (Process Name, Part Number, Prepared By, Date): Complete the header information as required by filling out the appropriate boxes. The information should agree with the Time Observation Sheet and the Standard Operations Routine Sheet. BEFORE CI: 2. Prepare an appropriate scale for this graph. The scale should be written in along the “Y” axis (left hand, vertical axis) of the chart. The “Y” axis will indicate the time segments, either in seconds or minutes, needed to record actual times observed for the operators and or machines. The “X” axis (horizontal line) of the chart will indicate either operators or machines. 3. At the appropriate level, draw in the Takt Time line. Procedure: Cycle Time / Takt Time Bar Chart

4. Bar Charting: Create a bar chart for the total cycle time for each operator and/or machine in the process. This will be drawn in on the graph format and labeled appropriately. Each operator and/or machine will have a separate bar on the chart. Use the legend at the side of the chart to visually show if the time is: a) Machine Only, b) Operator & Machine, and c) Operator Only. 5. Calculations: In the upper right hand corner of the worksheet, the formula for the operator requirements calculation is written. It is: Operator cycle times (in total) divided by the Takt Time. Total all of the operator cycle times as charted on the Bar Chart, and place this number in the numerator portion of the equation. Write in the calculated Takt Time in the denominator of the calculation and perform the division. The quotient of this calculation is the total number of operators required. Place the quotient (total number of operators required) in the space provided under the calculation. Perform the same calculations when dealing with machines. 6.
