Knowing the Takt time helps us to estimate the production time of a product to cover the request coming from the customer. The takt time helps us to achieve a consistent and continuous production flow. Eliminate the waste of overproduction with a production that reflects the real needs of the customer. Encourage the development of standardized work instructions by promoting quality and efficiency. Most importantly, it allows us to set production goals in real time, showing staff where the process is right.

Steps

Step 1. Understand what Takt time is

The takt time is the production rate (for example, one piece per minute) that aligns production to customer demand.

  • In simple terms, it represents the production time of a product sufficient to cover the request from the customer.
  • Calculation of takt time = available time / customer demand. For example, if a customer requests 100 light bulbs a day, the takt time will be 8 hours / 100.
  • 8 hours is the time worked in a 9-hour work day (you will need to exclude breaks, hours spent in meetings, etc.) to enter the available time in the numerator.
  • This means that each bulb will take 4 to 8 minutes to complete.

Step 2. Calculate your question

For example, what does your end user / customer normally request each day / week / month?

Step 5. Compare the production cycle time with the takt time using any graph, preferably a bar graph

Step 6. Draw a mapping of the value stream, you will be able to provide and take into account the takt time at each step of the activity

Advice

  • Producing at a faster rate than takt time leads to overproduction, i.e. greater waste.
  • Producing at a lower rate than takt time leads to unwanted expectations on the part of the customer.
