Takt time, a concept, metric, or tool that originated in Germany’s aircraft production landscape decades ago, is an integral aspect of lean manufacturing today. In fact, it has been instrumental in Toyota’s phenomenal rise.
Takt (pulse or beat) time sets your manufacturing process’s pace in a way that it aligns perfectly with customer demand. Simply put, takt time refers to the rate at which you must manufacture an item to meet customer needs. It is the amount of time available to produce a product or part.
So, let’s dig into this metric deeper as well as the associated calculation, how takt time contributes to continuous improvement, and more.
What Exactly Is Takt Time and Why Is It the Heartbeat of Production?
The formula shared below indicates how you can optimize your production capacity with it:
Takt time = Available production time per period / Customer demand over that period
Hence, by matching production with demand precisely, this production pacing helps prevent underproduction or overproduction. You get to increase overall efficiency, minimize waste, and reduce inventory expenses.
Here are some other reasons why takt time is deemed as the production ecosystem’s heartbeat. You can:
- Spot and expose bottlenecks and inefficiencies easily
- Improve capacity planning
- Create standard work routines
- Schedule production in a data-centric manner
- Provide operators with real-time targets so they can make the most of their shifts
- Maintain an even, consistent, sustainable workflow
Takt Time vs. Cycle Time vs. Lead Time: Clearing up the Confusion
In lean manufacturing, takt, cycle, and lead times mean different things, as explained below:
- Takt Time
This is the maximum duration you need to produce each unit to satisfy customer demand.
- Cycle Time
This refers to the time actively spent by your team while working on an order.
- Lead Time
It is the time that passes between the receipt of an order and value delivery to the customer.
Hence, while cycle and lead times focus on the progress of work, this metric reflects the actual pace of production. Managers need to account for all three metrics when assessing workflow performance.
How to Calculate and Adjust Takt Time Based on Demand Rate
As mentioned before, to calculate takt time, you need to divide the total production time available by customer demand during that span. And while using this formula, remember the following:
- Use consistent time frames to define production time as well as customer demand to obtain accurate results.
- Only include the time during which your team will be actively creating value for the end user. Exclude breaks, shift changes, and planned maintenance.
- For customer demand, use short time frames, like those involving a month or week.
Here’s an example to make it all clearer. Say, a shirt company XYZ operates in 8-hour shifts.
- The total duration of a shift is (8×60) 480 minutes
- Breaks and downtime account for 45 minutes
- Hence, the total available time is (480-45) 435 minutes
- And the customer demand per shift is 210 units
By applying the formula, you can easily find that:
Takt time = 435 minutes / 210 units = 2.07 minutes/unit
In other words, you must churn out one shirt every 2.07 minutes to meet customer demand smoothly and efficiently.
Now, in many industries, be it electronics or automotive, demand tends to fluctuate due to order ups and downs, seasonality, and market variations. In such scenarios, this is how to adjust takt time:
- If Demand Rises
You must shorten the production pace in this case as production speed must increase to meet the new demand. For instance, if you have to now produce 300 units within 435 minutes, the takt time will be 1.45 minutes per unit.
And this can be accomplished by adding more machines and operators, automating repetitive tasks, or removing bottlenecks.
- If Demand Falls
In case the demand rate falls from 210 to 150 say, your takt time will shoot up (2.9 minutes per unit). So, you will have more time to produce every unit. And to prevent excessive production, you can slash the usage of equipment or labor.
- If Time Available Changes (Demand Stays Same)
Imagine the available production time drops to 400 minutes from 435 minutes due to sudden downtime, extra breaks, or shift pattern changes. Demand remains same though, at 210 units.
In such a scenario, your takt time will be 1.9 minutes per unit. And to accommodate, you must improve uptime or allocate resources better.
What It Means When Cycle Time Is Greater (or Smaller) Than Takt Time
Cycle time and takt time are often compared to gauge the adequacy of the production capacity, when it comes to meeting customer demand. So, here’s what it means when cycle time is greater than, same as, or less than takt time:
- If cycle time exceeds takt time, demand is greater than your production capacity. Hence, you must optimize the manufacturing process or increase resources to meet the said demand.
- If cycle time equals takt time, your capacity is aligned with demand and the situation is ideal. The possibility of generating waste is also minimal.
- If takt time exceeds cycle time, capacity is greater than demand and poses the risk of overproduction.
How Takt Time Drives Continuous Improvement and Lean Culture
Continuous improvement and lean culture revolve around small, consistent actions that help reduce waste, augment operational efficiency, and deliver more value to customers over time. And this is how this production metric drives the same:
- Efficient Problem-Solving
If your production rate exceeds the defined takt time, the workflow design is inefficient or there are bottlenecks somewhere. However, if every unit is completed in less than the specified takt time, you risk overproduction.
Hence, with deviations easily visible, it becomes easier to take corrective actions promptly. You can also spot performance gaps by comparing cycle time and takt times, which can aid in better root cause analysis.
- Standardization
This production rhythm sets every workstation’s pace and ensures consistency in the execution of processes. This makes it easy to detect, analyze, and fix variations. The ultimate result is standardized work, which is the bedrock of continuous improvement.
- Better Resource Optimization
When you know the ideal production speed, it’s possible to allocate and schedule resources better. It reduces costs associated with operations, overproduction, inventory, waste, and overtime. Better resource optimization also implies fewer unnecessary movements, less waiting time, etc. Hence, overall productivity rises.
- Enhanced Collaboration and Decision-Making
Takt time makes it convenient to track and measure production performance for different teams. This translates to less finger-pointing, more collaboration, and smarter decision-making when it comes to addressing workflow disruptions. In fact, it becomes possible to resolve issues in real time. There is increased transparency, trust, and accountability at every level.
- Improved Quality
When the production rate is stable, you can predict and manage processes better. This means you have to deal with fewer product quality defects and variations. Instead of production quantity, operators can concentrate more on the quality and improve it in the long run.
- Reduced Risk
When you produce as per demand, you can minimize the losses and worries associated with unexpected market fluctuations or outdated stock. You can also adapt faster to changes in the market or demand.
- Proactive Culture
Being aware of the takt time allows everyone to work towards a realistic and clear target. Every frontline worker also has a decent understanding of their role in attaining the same. Hence, they can spot deviations immediately and make small improvements on an everyday basis.
A proactive culture develops over time, where everyone takes the necessary actions to minimize waste, boost the workflow, and satisfy customer demands just right. And that’s the soul of lean manufacturing.
- Customer-First Mindset
Takt time is a metric that depends directly on customer demand, which means you create value as per customer pull rather than internal push. In other words, it is customer demand that drives everything from production scheduling to performance measurement to decision-making.
Hence, this customer-first mindset helps you in delivering exactly what end users need and that too at the right time. And consequently, customer satisfaction and long-term loyalty improve, which means a stronger bottom line.
How to Digitalize Takt Time for Real-Time Performance Management
By aligning production with customer demand, this lean metric helps you ace lean manufacturing in more ways than one. From solving problems efficiently and utilizing resources optimally to standardizing work and fostering a proactive culture, this metric allows you to practice continuous improvement.
