"Takt time is the heartbeat of a lean system." -Jim Womack
What is Takt Duration?
Takt Time refers to the total time required to complete a product or service. It is especially used in Just-in-Time processes.
Takt Duration History
Takt is a German term for a clear time interval, such as musical meter.
Takt time was first used as a production management tool in the German aircraft industry in the 1930s. Takt was the time interval during which the aircraft was advanced to the next production station. This concept began to be used within Toyota in the 1950s and was widely used among Toyota suppliers from the late 1960s.
How to Calculate Takt Time?
Step-1 - Determination of Working Time: The total working time required to complete the job is calculated. This account includes man/hour and physical transactions. The complexity of the job should also be taken into account when making this calculation.
Step-2 - Converting Working Time to Seconds: Since Takt Time is usually calculated in seconds, the time is converted to seconds. For example; If the total duration of a job is 1 hour, it is calculated as 1 hour x 60 minutes x 60 seconds = 3,600 seconds.
Step-3 - Determining the Demand Amount: When calculating the Takt Time, the daily production target or demand amount of the production line is also calculated.
Step-4 – Final Calculation - Takt Time Calculation: Takt Time = Working Time (seconds) / Demand Amount
Total run time: 3,600 seconds = 1 hour
Daily demand: 100 items
Takt Time = 3,600 seconds / 100 items = 36 seconds
According to the above calculation, 1 unit of product is produced every 36 seconds. This is considered the Takt Time of the business process.
Where and How to Use Takt Time?
Production: Takt Time is used to optimize production processes and ensure that products are produced at the specified speed. Completing the work on the production line at equal time intervals increases efficiency and ensures that products reach customers faster.
Supply Chain: Takt Time can be used in Supply Chain Management to optimize the speed of transportation and distribution of goods.
Construction: In Construction Projects, Takt Duration Man/Hour calculation is used.
Risks in Takt Time Calculation
Complexity: Application of Takt Time can cause business processes to be unnecessarily separated or combined, ultimately becoming more complex. This complexity of processes can also lead to management difficulties.
Human Factor: Workers' productivity and motivation can affect the success of Takt Time implementation. Workers may feel overly stressed when they have to work faster.
Cost Increases: Implementation of Takt Time may require investment to optimize business processes. These investments may cause initial costs to increase.
Lack of Flexibility: Takt Time aims to complete business processes at a certain pace. This can make business processes less flexible and make it harder to adapt to changing conditions.
Training and Implementation Challenges: It is important to implement Takt Time correctly and teach this concept to employees. Training and implementation difficulties can hinder success.
Quality Issues: Since Takt Time aims to speed up business processes, quality control may become difficult. Precautions must be taken to maintain quality.
Resistance and Acceptance Issues: There may be resistance to implementing Takt Time within the business. It may take time for employees and managers to accept and adopt this change.
Comparison with Unit Man/Hour
Unit Man/Hour calculation calculates the labor required to do a job. This period does not include the time the relevant product or job waits independently of the worker.
Takt time isa refers to the total time required to complete a product or service, including Unit Man/Hour Calculation.
