Lean Manufacturing: The Way to Transform Your Business (Part 2)

Lean Production Techniques: SMED, Poka-Yoke and Kaizen

Lean manufacturing involves many techniques and methods to increase efficiency and eliminate waste. Here are some important techniques:

1. SMED (Single-Minute Exchange of Die) – Fast Setup Techniques: Aims to reduce setup times in production processes. Shorter setup times make it possible to produce in smaller batches, which reduces inventory costs and enables faster response to customer demands.
2. Poka-Yoke (Error Prevention Mechanisms): Includes mechanisms used to prevent production errors. The aim is to prevent errors from occurring, or at least to detect and correct them at an early stage. This improves product quality and customer satisfaction.
3. Kaizen (Continuous Improvement): Represents an approach of small and continuous improvement. Everyone is encouraged to generate and implement ideas to make processes better, every day. Through Kaizen, companies continuously improve and gain a competitive advantage.

ERP and Lean Manufacturing Integration

In today’s manufacturing world, Enterprise Resource Planning (ERP) systems are widely used to integrate business processes and increase productivity. However, ERP systems often work with a “push system” mentality, while Lean Manufacturing is based on a “pull system” approach. The integration of these two approaches can help companies make their production processes more agile.

Differences between TPS and Lean Manufacturing

Although the terms Toyota Production System (TPS) and Lean Manufacturing in the Western world are often used interchangeably, there are some important differences. While TPS is based on Toyota’s corporate culture and Japanese management approach, Lean Manufacturing is an implementation methodology derived from TPS in the Western world.

Real Life Examples and Case Studies

Lean manufacturing techniques are practiced by many large companies around the world. Here are some notable examples:

1. Toyota – Continuous Improvement with TPS Toyota has developed the Kanban system and JIT (Just-in-Time Manufacturing) processes, forming the basis of lean manufacturing methodology worldwide. In this way, Toyota achieves maximum production efficiency with minimum inventory levels.

2. Intel – Reducing Production Changeover Times with SMED Intel has reduced the changeover times of chip production lines by 40% by implementing SMED (Rapid Mold Changeover) in its production facilities.

3. Nike – Inventory Optimization with Pull System Nike has eliminated unnecessary stocks in the supply chain by adopting lean manufacturing principles and created a production model based on customer demand.

4. KazTek Invest – Lean Manufacturing Success in Kazakhstan KazTek is an Almaty-based manufacturer of lighting products and signed a Lean Manufacturing consulting agreement with Lean Solutions in 2023. Among the lean manufacturing techniques implemented in this process are the following:

• 5S System: Making the workplace organized, clean and efficient
• SMED Reducing set-up times for injection molding machines
• Kanban System: Optimizing inventory management and implementing a pull system
• Two-bin Material Feeding: Optimizing material flow in production
• Kaizen Practices: Ensuring continuous improvement through before-and-after analysis
• Production Planning and Capacity Control: Managing factory capacity more effectively

Achievements at KazTek:

• Stocks were reduced by 70%.
• Production performance increased by 50%.
• Labor costs were reduced by 30%.
• OTIF rate increased to 80%.
• Workplace safety and employee satisfaction increased.

This success demonstrates that lean production provides an important competitive advantage not only for large global companies but also for regional producers.

CONWIP System and Workload Balancing

Workload balancing is of great importance in lean production. One of the methods used for this is the CONWIP (Constant Work-In-Progress) system. CONWIP is a production management system that provides a continuous workflow to control the workload in the production process. Although it is similar to the Kanban system, the main difference is that it balances the workload across the entire production line and keeps inventory levels under control.

Kanban Stockless Production with Pull System

Kanban is the basis of the pull system used in lean manufacturing. This system directs production based on customer demand and is one of the most important tools of the Just in Time (JIT) philosophy.

How Does the Kanban System Work?

1. Production on Demand: Production is determined in line with customer demand and unnecessary stock accumulation is prevented.
2. Management with Cards: Each production step is managed with Kanban cards and determines when production should start.
3. Optimization of the Production Process: By ensuring continuous flow, unnecessary waiting, inventory costs and labor wastage are reduced.

The Kanban system is a key component of the Toyota Production System and is used in conjunction with continuous improvement (Kaizen) to achieve manufacturing excellence.

Basic Principles of Lean Production

Lean Production is based on five basic principles:

1. Value: Identifying the characteristics of the product or service that the customer really needs and is willing to pay for.
2. Value Stream: Analyzing production processes and eliminating elements that do not add value.
3. Continuous Flow: Ensuring that production runs smoothly and without interruption.
4. Pull System: Shaping production according to customer demand and minimizing inventory costs.
5. Pursuing Perfection: Achieving better every day with a culture of continuous improvement (Kaizen).

Advantages of Lean Production

• Reducing Costs: Minimizes production costs by eliminating waste.
• Quality Improvement: Improves product quality by enabling early detection of defects.
• Faster Deliveries: By optimizing processes, production speeds up and customer demands are met in less time.
• Employee Engagement: Encourages the involvement of team members in continuous improvement processes.
• Efficient Use of Resources: It enables businesses to use energy, materials and manpower more effectively.

Conclusion Start Implementing Lean Manufacturing!

Lean Production is a management approach that can be applied not only for manufacturing companies but also in many other areas such as service sector, logistics and retail. It is a powerful strategic tool for any business that wants to reduce costs, increase quality and ensure customer satisfaction by eliminating waste.

To succeed in today’s competitive environment, adopt the lean mindset and integrate the culture of continuous improvement into your business processes. If you want to make your business more efficient and achieve sustainable growth, you should start Lean Manufacturing today!
