    What is Takt Time? How to Calculate and Reduce a Key Demand Metric

    Table Of Contents

      The Industrial Internet of Things (IIoT) is transforming how manufacturing companies measure and improve processes. By using a machine data platform, companies can rapidly realize fast ROI and unprecedented improvements in efficiency and productivity.

      But industrial IoT and machine data platforms alone aren’t magic wands that can be waved to create new value. While they do empower accelerated process improvement across an enterprise, they still need established measurement metrics and KPIs to provide context to the insights a machine data platform generates.

      Measurements like takt time can give meaning to what the data shows, driving analytics and insights. Managers can view performance and implement changes where needed.

      What is Takt Time?

      Takt time is the rate at which production must operate to meet customer demand.

      When customers order products, they’re given lead times regarding when they can expect their goods. Takt time is used to measure a manufacturer's output against demand.

      But it’s more than just increasing machine speed. A complex manufacturing operation requires multiple orders and order quantities from many customers. Companies within the same industry will have different takt times based on equipment age, minimum production lot sizes, and other factors. Looking at takt time individually and holistically provides valuable information to management.

      If takt time is shortened, the operation is more efficient and has the capacity for new orders. If it exceeds what is needed to meet the lead time, processes are less efficient and customer dissatisfaction is high. Because of this, takt time helps measure the efficiency of a manufacturing operation.

      Don't get confused with lead time and cycle time! What’s the difference between Takt Time, Cycle Time, and Lead Time?

      How Do You Calculate Takt Time?

      The calculation of takt time is straightforward: the number of workable production hours divided by the number of units in manufacturing orders. Workable hours within the calculation shouldn’t include breaks, lunches, and other stops.

      Takt Time (TT) = Workable Production Hours (PW) / Units Required by Customer (UR)

      or

      TT=PW/UR

      How to Calculate Takt Time Formula.

      The traditional measurement of takt time relied upon manual data tracking, calculation, and analysis. Today, machine data platforms that record data in real-time can automatically calculate takt time.

      This real-time access to takt time means managers can identify and respond to bottlenecks quickly. As production needs, inventory levels, and supply chain issues come into play, a machine data platform will deliver insights based on a data-driven, accurate takt time. Managers can understand what is happening on the production or shop floor and what needs to be done.

      How Do You Reduce Takt Time?

      Because takt time is the speed production must run to meet demand, it’s only reduced by optimizing processes. Continuous improvement initiatives can help align takt time with demand; as processes improve, the cycle time of each product becomes more aligned with the required speed.

      There are several ways to optimize processes and reduce takt time:

      Measure Individual Cycle Times and Other Metrics

      Cycle time is the time spent producing a good from raw material to the final product. Most manufacturing companies have many different products in their portfolio. The blend of other products ordered by customers is the "product mix" in production at any given time.

      By measuring the cycle times and understanding their complexity, companies can plan resources for periods where takt time may be greater or lesser than desired. This measurement helps them make decisions in scheduling and planning to balance out takt time.

      Other process metrics to consider include:

      • Efficiency: Production time divided by total process time
      • Turnaround Time: Time from order placement to delivery
      • Throughput: The number of produced units divided by the amount of production time for each unit
      • Quality Rate: The percentage of first-quality parts divided by the total units produced

      Remove Non-Value-Added Time

      A core principle of Lean and Six Sigma Methodologies is removing non-value-added time or waste. As improvement teams study and measure a product's cycle times and other performance attributes, they can divide activities and tasks into value-added and non-value-added time.

      By eliminating the non-value-added time from process steps and formalizing it in the part's workflow, cycle time per product is lower. This leads to reduced takt time for the day, week, or other period being observed.

      Consider Your Overall Equipment Effectiveness (OEE)

      OEE is another way to review and improve processes. OEE considers availability, performance, and quality, and many companies assume their OEE is much higher than it is. By looking at the causes of downtime, companies can increase their OEE, and in turn, decrease their takt time.

      Improving Takt Time with MachineMetrics

      Once a team has assessed production, taken performance benchmarks, and identified the root causes of problems, they can implement strategies to improve processes. The best way to do this is by using real-time machine data.

      Improvement methodologies like Lean and Six Sigma began before the age of industrial IoT. But with advanced machine data platforms like MachineMetrics, processes can be taken to the next level with greater data accuracy and more actionable data.

      Here are a few ways MachineMetrics can help you to reduce takt time:

      1. More Efficient Processes: Real-time data is captured for all machines throughout the factory floor, so managers can view up-to-date production conditions. This visibility encompasses the velocity and current status of the entire product mix on the shop floor. Decision-makers can craft new strategies built on this data to manage schedules, improve forecasting, and execute production plans better.
      2. Optimized Inventory Strategies: Demand shifts over time. With real-time data and the insights produced by advanced analytics, inventory purchase, delivery, and allocation strategies are aligned with demand. They can also be linked seamlessly with ERP or planning software.
      3. Accurate Holistic View of Production: A nightmare schedule of a complex mix of products may seem like an impossible burden on takt time. With a machine data platform, managers and planners can pace the scheduling of orders across multiple time sets to smoothen and reduce takt time as process improvement and inventory optimization takes hold.

      Real-time data and advanced analytical insights drive process improvement, inventory optimization, waste reduction, OEE, and quality management strategies. These improvements mean that takt time can be reduced so that companies realize a competitive advantage.

      MachineMetrics creates significant value that enables sales and marketing teams to reduce lead time for delivery. This reduction increases customer satisfaction and improves brand recognition.

      Takt time is a valuable core metric for manufacturing production. Ensuring you have the accurate data necessary to track and reduce takt time is increasingly important given growing market competition.
