In a world where every euro counts and competitive pressure is constant, optimizing resources has become a necessity for all companies, including SMEs. Lean Management, often associated with Japanese factories or large industrial chains, actually offers simple, effective, and accessible principles for all. At the heart of this approach: waste elimination. But for it to be effective, it must become everyone’s business. Let’s take a closer look.

What Is Lean Management?

Lean Management is a work organization method born at Toyota, aimed at maximizing customer value while minimizing waste. The goal? Do more with less: less time, fewer resources, fewer errors — and more satisfaction.

In practice, Lean is built on two pillars:

• Continuous process improvement
• Respect for people

Above all, it is based on a fundamental principle: eliminate anything that does not add value for the customer.

The 7 Types of Waste to Eliminate

Lean identifies 7 classic types of waste, known as muda in Japanese. They exist in every sector, often go unnoticed at first glance, yet are costly on a daily basis.

1. Overproduction: producing more than needed, too early or too fast.
2. Waiting time: a machine down, a colleague running late, a file that’s delayed.
3. Unnecessary transport: moving products, documents, or people without added value.
4. Excess inventory: raw materials, documents, or data waiting to be used.
5. Unnecessary motion: looking for a tool, walking across the office, clicking through endless menus.
6. Overprocessing: complex tasks, redundant steps, duplicate controls.
7. Defects and rework: errors, bugs, non-conformities to be corrected.

Each waste has a cost. Sometimes financial, often human. And today’s small losses can become tomorrow’s major pains.

Why Waste Elimination Involves Everyone

It’s common to think that process improvement is a job for management, experts, or consultants. In reality, those who experience the problems daily are best placed to detect and solve them. That’s why, in a Lean approach, all employees are change agents.

Involving everyone means:

• Better detection of waste
• Stimulating creativity and the drive to propose solutions
• Fostering engagement and a sense of ownership

When a technician spots an unnecessary step in a procedure, when an assistant suggests a clearer document template, or when a logistics team reorganizes its workspace — that’s Lean in action.

How to Embed This Culture in the Company

1. Start from the Top

As with any transformation, leadership commitment is essential. Management sets the tone and shows that waste elimination is not a passing trend, but a strategic priority.

Concrete actions:

• Explain the expected benefits using relatable examples
• Share a clear vision: “zero unnecessary waste”
• Lead by example (efficient meetings, fast decisions, etc.)

2. Raise Awareness and Train Teams

You can’t eliminate what you don’t see. Waste must be made visible, and this starts with training — which can be simple and pragmatic.

Concrete actions:

• Organize “walks” through offices or workshops to identify waste together
• Train teams on the 7 muda with real examples from the company
• Build a shared vocabulary: everyone should speak the same language

3. Use Simple Tools

Lean is not a complicated system. It relies on visual, participatory tools that are easy to understand and use.

Useful tools:

• Improvement boards (problems, ideas, actions, results)
• The “5 Whys” to identify root causes
• Visual management: clear displays, color codes, sticky notes
• Daily routines: a set time to discuss problems and ideas

4. Recognize Initiatives

Every improvement, no matter how small, deserves recognition. That’s what fuels action and builds positive momentum.

Concrete actions:

• Publicly praise effective ideas and efforts
• Highlight concrete results: time saved, errors avoided, satisfied clients
• Launch a monthly “Top 3” of the best field ideas

5. Make Improvement a Daily Habit

Lean should not be a side project — it must become a natural way of working, embedded in meetings, conversations, and decisions.

Concrete actions:

• Start team meetings with a quick round of recent improvements or frustrations
• Dedicate 10 minutes per week per team to identify one waste
• Encourage small actions over large reforms

Benefits at Every Level

When waste elimination becomes a shared mission, the results quickly follow.

For the company:

• Fewer hidden costs
• Smoother processes
• Improved responsiveness

For teams:

• Less frustration
• Simpler daily work
• Increased recognition

For clients:

• On-time delivery
• Fewer errors or delays
• A more satisfying experience

Anticipating Common Obstacles

Naturally, it’s not always smooth sailing. Some resistance may appear:

• “We’ve always done it this way”: Lean challenges habits
• Fear of being judged: requires a climate of trust and psychological safety
• Lack of time: paradoxically, identifying waste saves time, but requires space to start

One good way to overcome these hurdles: start small, prove it works, then expand.

Key Takeaways

• Lean Management is about creating value by eliminating waste.
• These wastes (overproduction, waiting, defects, unnecessary motion, etc.) exist in all businesses, even the smallest.
• Waste elimination shouldn’t be left to experts: everyone can help identify and fix inefficiencies.
• Leadership involvement is key to driving the approach and making it a strategic priority.
• Training and awareness help make waste visible and unlock collective intelligence.
• Simple tools like visual boards, “5 Whys,” or team routines are enough to kickstart momentum.
• Recognizing initiatives builds motivation and embeds long-term change.
• Making improvement part of daily work is essential to building a culture, not just a project.
• A shared effort to eliminate waste improves work life, operational performance, and customer satisfaction.
