Calculate Takt Time

How to Calculate Takt Time

To accurately calculate takt time for optimizing manufacturing processes, you must gather two crucial pieces of data: Available Production Time and Customer Demand. Takt time, represented as Takt Time = Available Production Time / Customer Demand, measures the pace at which products must be manufactured to meet customer requirements.

Understanding Available Production Time

Available Production Time is the total time available for production activities, deducting any breaks, changeovers, and excluding non-operational times. However, it includes budgeted downtime which is accounted for in advance. For example, in an 8-hour shift subtracting a 10-minute break and a 20-minute lunch, the production time effectively becomes 450 minutes.

Determining Customer Demand

Customer Demand is defined by the number of units that must be produced to meet customer needs within a specific time frame. It's essential to note that this demand should be mapped over the same time horizon used for calculating production time, ensuring consistency and accuracy. For instance, if the goal is to manufacture 17,500 parts per week with one shift per day, the daily demand equals 3,500 parts.

Calculating Takt Time

Once you have identified the Available Production Time and Customer Demand, apply the takt time formula: Takt Time = Available Production Time / Customer Demand. This calculation will provide the time available to produce each unit, facilitating paced production aligned with customer demand. For example, with 450 minutes of production time and a need for 3,500 parts, the takt time would be approximately 7.72 seconds per part.

Understanding and applying these calculations helps ensure production efficiency and aligns manufacturing outputs with market demand, essential for operational success.

How to Calculate Takt Time

Takt time is a critical metric in manufacturing that helps align production speed with customer demand. Calculating takt time correctly ensures efficient resource use and optimal productivity. To calculate takt time, follow these detailed steps:

Step 1: Define Production Time

Identify the total available production time for a given period. This should include only the time when actual production occurs and exclude any periods of planned downtime, such as breaks or maintenance stops. For example, if a shift lasts for 8 hours with a 10-minute break and a 20-minute lunch, the production time totals 450 minutes.

Step 2: Determine Customer Demand

Calculate the total number of units required by customers over the same time period as your production time. This figure should cover all the parts needed to meet customer orders. If the target is to produce 17,500 parts across 5 shifts, then the daily customer demand equates to 3,500 parts per shift.

Step 3: Apply the Takt Time Formula

Using the derived figures from Steps 1 and 2, apply the formula Takt Time = Production Time / Customer Demand. For instance, with a production time of 450 minutes and a demand of 3,500 parts, the takt time would be approximately 0.1286 minutes (or roughly 7.72 seconds) per part.

Understanding and utilizing this calculation helps ensure that production pace meets customer demand efficiently, preventing resource overuse and manufacturing delays. By mastering takt time calculation, project managers can fine-tune production processes, manage competing schedules effectively, and minimize waste.

Examples of Calculating Takt Time

Example 1: Standard Factory Operation

To calculate takt time in a factory that operates 20 hours daily and must produce 400 units, use the formula: Takt Time = Available Time / Required Units. Here, Available Time = 20 hours = 72000 seconds, and Required Units = 400. Thus, Takt Time = 72000 / 400 = 180 seconds per unit. This example illustrates basic takt time calculation in a manufacturing context.

Example 2: Variable Demand

Consider a service center processing different quantities of requests per day. If the center operates for 8 hours (28800 seconds) and expects 600 requests, the takt time calculation is straightforward: Takt Time = 28800 / 600 = 48 seconds per request. This example demonstrates takt time's application in service industries with varying daily demands.

Example 3: Multiple Products

For a production line that produces three types of products with equal priority, assuming an operation time of 9 hours (32400 seconds) and a demand for 200 units of each type, calculate the takt time per product type: Takt Time = 32400 / (200 * 3) = 54 seconds per unit. This scenario highlights takt time calculation in a diversified production environment.

Example 4: Adjusting for Breaks and Downtime

If a workshop has scheduled breaks totaling 1 hour within a 10-hour workday, and needs to output 450 units daily, adjust the available time: Available Time = (10 hours - 1 hour) * 3600 seconds = 32400 seconds. Then, calculate takt time: Takt Time = 32400 / 450 = 72 seconds per unit. This example accounts for realistic work conditions that include breaks and downtime.

Example 5: Increased Productivity Goals

When a factory sets a goal to increase productivity by 20%, recalculating takt time becomes necessary. Assuming the original takt time was 50 seconds per unit for 500 units over an 8-hour day, the new unit goal becomes 500 * 1.20 = 600 units. Thus, new takt time is Takt Time = 28800 / 600 = 48 seconds. This illustrates how takt time adjustments can support efficiency improvements.
