What Are Lean Techniques?

Lean techniques are practical tools and methods that help businesses work smarter by reducing waste and improving the way tasks are done. For example, they involve organising workspaces so everything has a place (like the 5S method), scheduling work to match customer demand (Takt Time), or using visual tools like Kanban boards to track progress.

The idea behind lean thinking is to simplify processes, save time, and reduce costs, all while delivering more value to customers.

Why Are Lean Techniques Important?

Lean techniques are important because they help businesses solve everyday problems like disorganisation, wasted time, and high costs. By improving workflows and making processes more efficient, lean management can make your business more productive and increase ROI.

Studies also back up how effective lean techniques are. Research in the International Journal of Production Economics shows that lean practices can directly improve financial performance, and even back in 2003, it was proven that lean methods have a positive impact on operational efficiency.

 

1. 5S: Organising for Efficiency

The 5S methodology is a lean technique that focuses on creating and maintaining an organised, efficient, and safe workplace. By breaking it down into five actionable principles, 5S provides a clear roadmap for creating lasting improvements:

• Sort: Clear out the clutter by identifying and removing unnecessary items.
• Set in Order: Arrange tools and equipment in a logical way so everything has a place and can be easily found when needed, saving time and effort.
• Shine: Keep your workspace clean and tidy with regular maintenance.
• Standardise: Develop clear procedures and guidelines to ensure everyone follows the same organisational practices.
• Sustain/Systemise: Build habits and routines to embed these practices into everyday work, making 5S a permanent part of your workplace culture.

Benefits of 5S

• Reduced Inefficiencies: Implementing 5S ensures workspaces are organised and easy to navigate. Employees spend less time searching for tools or materials, reducing delays, distractions, and wasted effort.
• Visual Organisation: One popular tool used in 5S is shadow boards, which provide a visual way to organise tools. These boards have outlined spaces for each tool, ensuring everything has a designated place and can be quickly returned after use. Shadow boards not only save time but also reduce the likelihood of misplaced or lost items.

Real-World Application of 5S

A client in the food and beverage industry approached us looking to enhance their 5S system. They needed custom solutions, including cleaning stations with matching colour-coded equipment and dry erase production boards, to create a more organised and efficient workspace.

We designed branded cleaning stations featuring shadow boards to keep tools perfectly organised and accessible, ensuring everything had its place.

To add flexibility, we also supplied mobile versions built on steel frames with locking casters, while the production boards were customised with document holders and dedicated health and safety sections.

2. Just-In-Time (JIT): Reducing Waste

Just-In-Time (JIT) is a lean manufacturing principle designed to produce only what is needed, when it is needed. This approach is known as a pull system because production is driven by actual demand rather than predictions or schedules.

Instead of holding large amounts of inventory, JIT focuses on delivering materials and components just in time for production, and producing finished goods just in time to meet customer demand.

Benefits of JIT

• Reduced Inventory Costs: With JIT, businesses avoid overstocking and the associated storage costs. By maintaining minimal inventory levels, companies save money while reducing the risk of items becoming obsolete or damaged.
• Improved Responsiveness: JIT enables businesses to respond quickly to customer demands and market changes. By aligning production schedules closely with demand, organisations can deliver the right products at the right time, improving customer satisfaction.

Real-World Application of JIT

A great example of Just-In-Time (JIT) implementation is Toyota, which pioneered the approach in its manufacturing processes, known as the Toyota Production System. At the right time for assembly, Toyota minimised inventory storage costs and improved responsiveness to customer demand.

This strategy allowed Toyota to maintain high-quality standards whilst eliminating waste, setting a benchmark for lean manufacturing.

 

3. Kaizen: Continuous Improvement Methodology

Kaizen is a Japanese term that translates to “change for the better” or “continuous improvement.” It originated in Japan with the Toyota Production System and became a cornerstone of lean manufacturing. At its core, Kaizen focuses on making small, incremental improvements to processes, systems, and workflows over time.

Benefits of Kaizen

1. Culture of Continuous Improvement: Kaizen enables employees at all levels to contribute to process improvement. By involving everyone in identifying inefficiencies and suggesting solutions, it creates a culture where improvement becomes a shared responsibility.
2. Improving Workplace Organisation: Kaizen integrates with other lean tools, such as the 5S methodology, to enhance organisation and create safer work environments.

Example of Kaizen Implementation

Let’s say a factory wants to improve production processes using Kaizen principles. Workers assembling parts might spend too much time walking back and forth to collect materials or tools, which slows production and causes fatigue.

To address this, the team could redesign the workstation by placing frequently used materials within arm’s reach and organising tools on easily accessible shelves. Tools could be grouped logically based on the sequence of tasks, while heavy items could be stored at waist height to reduce bending and lifting.

 

4. Jidoka: Autonomation for Quality Control

Jidoka, often referred to as “autonomation,” is a lean technique that integrates automation with human oversight to ensure quality control. Also originating from the Toyota Production System, Jidoka enables machines to detect abnormalities or defects and halt production immediately. This allows human operators to address the issue before it affects the overall process.

Benefits of Jidoka

• Enhanced Efficiency: Automation handles repetitive tasks, allowing human operators to focus on problem-solving and continuous improvement.
• Balanced Creativity and Control: The integration of human oversight ensures that creative thinking and problem-solving remain part of the process, even in highly automated systems.

Jidoka Example

As an example of Jidoka, think of a car assembly line where components like bolts or wiring harnesses are fitted into the vehicle frame. If a bolt is not secured properly or a harness is misaligned, the sensor detects the anomaly and automatically halts the machine.

At this point, an alert is triggered, notifying the operator of the exact issue. The operator can then inspect and resolve the problem—whether it’s reseating the misaligned part or replacing a faulty component—before restarting the production line.

 

5. Kanban: Visual Workflow Management

Kanban is a flexible visual management tool that helps teams organise workflows and improve efficiency. While it’s often used as a board with cards representing tasks and columns like “To Do,” “In Progress,” and “Done,” Kanban can take different forms depending on the process.

For example, FIFO boards (First-In, First-Out) are used in the Kanban method to ensure older stock or tasks are processed first. Tags representing stock are placed on the board, and operators take the oldest tag to use first, reducing waste and ensuring proper stock rotation.

Benefits of Kanban

• Prioritising Tasks: By focusing on a limited number of tasks at a time, Kanban prevents overloading and ensures resources are allocated to the most critical work.
• Enhancing Communication: The transparency of Kanban boards fosters better communication among team members and ensures everyone is aligned on priorities and progress.

Kanban Example

Consider a manufacturing facility that uses a FIFO board to manage its inventory. Each batch of materials is represented by a tag, placed in the order the stock arrives. Operators take the oldest tag first, ensuring materials are used in the correct sequence. If tags for older stock start to pile up while newer ones continue to arrive, it signals a bottleneck, prompting managers to address the issue and reduce waste caused by expired or obsolete inventory.

 

6. Takt Time: Synchronising Production

Takt Time is a lean production tool that ensures the pace of a given manufacturing process aligns with customer demand. Derived from the German word “Takt,” meaning pulse or rhythm, it represents the maximum amount of time allowed to produce one unit to meet demand without overproduction or delays. Takt Time is often used in the Just-In-Time technique to ensure production is on track.

Benefits of Takt Time

• Reducing Idle Time: Takt Time ensures that resources—whether machinery or labour—are utilised effectively by eliminating unnecessary waiting periods or underused capacity.
• Improving Workflow Efficiency: With a clear production rhythm, teams can better synchronise their tasks, ensuring each stage of the process is aligned.

How to Calculate Takt Time

Calculating Takt Time is straightforward and relies on two key factors: available production time and customer demand. Here’s how it’s done:

1. Determine Available Production Time
   Calculate the total time available for production in a given period. For example, if your factory operates 8 hours a day, subtract breaks or downtime to find the net production time in minutes or seconds.
2. Understand Customer Demand
   Identify how many units your customers need during the same time period.
3. Apply the Formula
   Use the formula: Takt Time = Available Production Time ÷ Customer Demand

For example, If you have 7 hours (25,200 seconds) of production time in a day and your customers require 100 units, your Takt Time would be:
Takt Time = 25,200 seconds ÷ 100 units = 252 seconds per unit

This means your production process must produce one unit every 252 seconds to meet demand without overproducing or causing delays.

 

7. Poka-Yoke: Error Proofing

Poka-Yoke, a Japanese term meaning “mistake-proofing,” is a lean technique focused on preventing errors before they occur. It involves designing processes, tools, or systems that make it difficult—or impossible—for mistakes to happen. By integrating simple checks and safeguards into workflows, Poka-Yoke ensures that errors are caught early, preventing defects from reaching the final product or service.

Benefits of Poka-Yoke

• Reduced Rework: Poka-Yoke helps minimise errors, saving time and resources that would otherwise be spent correcting mistakes or redoing tasks.
• Improved Work Environment: By designing processes to prevent errors, Poka-Yoke reduces employee stress and builds confidence, as workers can trust the system to support their success.

Poka-Yoke Example

An example of Poka-Yoke is colour-coded cleaning equipment, which is commonly used to prevent cross-contamination between areas in healthcare settings. Green equipment is often designated for food preparation or kitchen areas, where hygiene is critical. Red equipment might be reserved for washrooms to ensure tools used in these spaces don’t accidentally come into contact with patient care areas, and blue or yellow tools are frequently assigned to general patient areas or wards.

 

8. Six Big Losses: Understanding Inefficiency

The Six Big Losses refer to the most common categories of inefficiencies that impact productivity in manufacturing and other industries. Originating from the Total Productive Maintenance framework, these losses highlight areas where time, resources, and output are wasted.

The Six Big Losses include:

1. Unplanned Stops: Downtime caused by machine breakdowns or malfunctions.
2. Planned Stops: Delays from scheduled equipment setup, changeovers, or adjustments.
3. Small Stops: Short pauses in production caused by temporary obstructions or operator inefficiencies.
4. Slow Cycles: Machines operating below their optimal speed, leading to slower production.
5. Production Rejects: Waste caused by errors in production, requiring rework or scrapping of materials.
6. Start-up Rejects: Losses during the initial stages of production, such as defective items produced during equipment warm-up.

Benefits of Addressing the Six Big Losses

1. Reduced Waste: By addressing defects and quality issues, businesses can save time and resources.
2. Overall Equipment Effectiveness: Regular maintenance and monitoring reduce breakdowns, ensuring smooth operations.

Six Big Losses Example

A manufacturing plant might struggle with frequent machine breakdowns and long delays during production changeovers. It’s frustrating for everyone, and the team knows it’s holding them back. By applying the Six Big Losses framework, they pinpoint these issues as major causes of wasted time and inefficiency.

To fix it, they start using predictive maintenance—installing sensors that flag potential machine problems before they turn into full-blown breakdowns. As a result, they would likely experience less downtime and higher employee satisfaction, because the system now works more effectively.
