TAKT Time

Overview

TAKT time is the amount of time available to produce one product or deliver one service. For example, if you have to make ten products in 1 hour (60 minutes), the TAKT time would be 6 minutes. If you make one product every 6 minutes, you would have made the required quantity of 10 at the end of the hour. TAKT time is a calculated number and not a measured number by cycle time. We can determine if the process can meet customer needs by comparing the cycle time to the TAKT time.

To add this tool to your workbook, click on Lean and then select TAKT Time.

Inputs

Click on Analysis Setup to open the menu options for this tool.

Setup

A sample screenshot of the setup menu is shown below.
inputs
1
Num Rows: Specify the number of rows of data you would like to enter on the worksheet. This information is used to format the worksheet. Note that any data below this formatted area will be cleared.
2
Time Units: Enter the units for the TAKT time. This is the unit in which the results would be computed and displayed.
3
Demand Period: The first input is the period of the analysis. Enter the duration that is considered for the product or process demand. Typically, this would be a month. The analysis results should not change what period we pick; we must ensure that we enter the rest of the data in sync with this period. For example, if you specify the period to be one month, you should enter the demand in units for one month.
4
Days/Month: The number of working days for the period of study. To derive this number, it would be best to subtract the days your company does not work (such as weekends).
5
Work Hours/Day: The total work hours per day. Here, you would consider if you are running your company in one, two, or three shifts. Don't enter any overtime that you occasionally do in this number.
6
Nonworking Hours/Day: The number of planned non-work hours per day, for example, lost in meetings,  lunch break, tea break, etc.

View Example: Click on this button to open the example file. You can view the example to get an idea of how to fill out this tool, or you can use the example as a starting point and modify it to meet your project needs.
8
Help Button: Click on this button to open the help file on this topic.
9
Cancel Button: Click on this button to exit without saving any changes.
10
Create Design: If this is your first time using this template, click this button to format the worksheet template. You can also update the worksheet format any time, but remember that you may lose any data entered on this worksheet. Once you are happy with the worksheet template layout, you must enter any required data on the worksheet. When the data entered into the worksheet is complete, you can click on Analysis Setup and then Compute Outputs to generate analysis results.
11
Analyze Design: Click on this button to save all changes and compute the outputs for this analysis. Review the results of your analysis and make changes to your inputs if required to update analysis results.
A sample screenshot of the worksheet is shown below.
outputs On the worksheet, enter the details of your products/services:
NumDescription
1The description of the product/service and the total demand per period. The period is the same one you defined in the dialog box.
2If there are multiple products, enter the above details for each of your products.

Charts

You will see the following dialog box if you click the Charts button. Charts
1
Title: The system will automatically pick a title for your chart. However, if you want to override that with your title, you can specify a title for your chart here. Note that this input is optional.
2
Sub Title: The system will automatically pick a subtitle for your chart. However, if you want to override that with your subtitle, specify a subtitle for your chart here. Note that this input is optional.
3
X Label: The system will automatically pick a label for the x-axis. However, if you would like to override that with your label for the x-axis, you can specify a different label here. Note that this input is optional.
4
Y Label: The system will automatically pick a label for the y-axis. However, if you would like to override that with your label for the y-axis, you can specify a different label here. Note that this input is optional.
5
X Axis: The system will automatically pick a scale for the x-axis. However, if you would like to override that with your values for the x-axis, you can specify them here. The format for this input is to determine the minimum, increment, and maximum values separated by a semi-colon. For example, if you specify 10;20, the minimum x-axis scale is set at 10, and the maximum x-axis scale is set at 20. If you specify 10;2;20, the x-axis increment is set at 2. Note that this input is currently disabled, and you cannot change this setting.
6
Y Axis: The system will automatically pick a scale for the y-axis. However, if you would like to override that with your values for the y-axis, you can specify them here. The format for this input is to determine the minimum, increment, and maximum values separated by a semi-colon. For example, if you specify 10;20, the minimum y-axis scale is set at 10, and the maximum y-axis is set at 20. If you specify 10;2;20, then, in addition to minimum and maximum values, the y-axis increment is set at 2. Note that this input is optional.
7
Horizontal Lines: You can specify the values here to add a few horizontal reference lines to your chart. The format for this input is numeric values separated by semi-colon. For example, if you specify 12;15, two horizontal lines are plotted at Y = 12 and Y = 15, respectively. Note that this input is optional.
8
Vertical Lines: You can specify the values here to add a few extra vertical reference lines to your chart. The format for this input is numeric values separated by semi-colon. For example, if you specify 2;5, two vertical lines are plotted at X = 2 and X = 5, respectively. Note that this input is optional.

Verify

If you click the Verify button, the software will perform some checks on the data you entered. A sample screenshot of the dialog box is shown in the figure below. Verify The software checks if you have correctly specified the input options and entered the required data on the worksheet. The results of the analysis checks are listed on the right. If the checks are passed, they are shown as green-colored checkmarks. If the verification checks fail, they are shown as a red-colored cross. The verification checks are shown in the orange exclamation mark if the verification checks result in a warning. Finally, any checks required to be performed by the user are shown as blue info icons.
1
Item: The left-hand side shows the major tabs and the items checked within each section
2
Status: The right-hand side shows the status of the checks.
3
Overall Status: The overall status of all the checks for the given analysis is shown here. The overall status check shows a green thumps-up sign if everything is okay and a red thumps-down sign if any checks have not passed. Note that you cannot proceed with generating analysis results for some analyses if the overall status is not okay.

Outputs

Click on Compute Outputs to update the output calculations. The following message is displayed upon successful completion of the analysis: outputs 2 You can read the total TAKT time and the contribution that each product/service makes to it. What-if analysis can also be performed to see how the TAKT time changes with product mix and demand changes.

Notes

Here are a few notes regarding this analysis:
  • Currently, you can enter up to 20 products. You can pick the most important products using the 80-20 rule if you have more products.

Examples

The following examples are in the software's Examples folder.
  • Calculate the TAKT time for a company that makes five main products operating one shift 5-day work-week (TAKT Time 1.xlsx).
