Lean can seem complex at first. Our goal is to make it simple, practical, and easy to apply,  so you can start seeing results right away. Let’s get started.

So, what lean tools should you focus on in 2025? That’s exactly what this section will cover. Before we dive in, here’s a quick overview of the 12 tools we’ll cover.

Tool	What it helps companies do
5S	Organize and clean your workspace
Value Stream Mapping (VSM)	See and improve workflow
Kaizen	Drive daily continuous improvement
Kanban	Visualize and manage workflow
Poka-yoke	Prevent mistakes before they happen
Just-in-time (JIT)	Reduce inventory and produce on demand
Jidoka	Build quality into the manufacturing process
Standardized Work	Improve consistency and training
Takt Time	Balance production to customer demand
Hoshin Kanri	Align goals with daily actions
Heijunka	Level and smooth production flow

And here are the top 12 lean manufacturing tools in details.

What are 5S tools, and why are they the foundation of a lean system?

If you’re new to lean, 5S is the perfect place to start. It’s simple, practical, and gives you quick wins. More importantly, it builds the habits and mindset that drive lean success.

5S is a lean system for creating an organized, efficient, and safe workspace. It stands for:

• Sort → get rid of what you don’t need
• Set in order → arrange what’s left so everything has a place
• Shine → clean the space so it’s easy to spot problems
• Standardize → create simple routines so everything stays organized
• Sustain → build habits so the system lasts over time

When your workplace is clutter-free and well-organized, employees waste less time. It’s easier to spot issues. Safety improves. Morale goes up. And lean practices become much easier to apply.

Here are some practical ways to start using 5S:

1. Walk the workspace and tag anything you don’t need (red-tagging works great)
2. Create clear labels and visual guides so tools and materials are easy to find
3. Schedule regular cleaning, and treat it as a key part of the job
4. Develop simple checklists to keep everything consistent
5. Hold quick 5S audits to make sure good habits stick

Tervene, as your lean management software, can help by giving you digital checklists and audit tools that make 5S routines easier to manage and follow.

And remember: start small. Focus on one area first. As you see the benefits, you’ll naturally want to expand.

How does Value Stream Mapping work?

Value Stream Mapping (VSM) helps companies see how work flows through their process, and where they get stuck. It’s one of the most effective lean tools for spotting waste and finding ways to improve flow.

Here’s the idea: You create a simple visual map of your manufacturing process, step by step. You show how materials, information, and tasks move from start to finish. Along the way, you highlight where delays, bottlenecks, and waste occur.

When you can see the process, it’s much easier to improve it.

You’ll use VSM to:

• Identify waste → spot unnecessary steps, delays, and rework
• Improve flow → make work move faster and smoother
• Visualize the process → get everyone on the same page about how things really work

A few practical steps to get started:

1. Pick a product or service to map
2. Walk through the entire process (don’t rely on guesswork)
3. Draw each step on a big sheet of paper or digital tool
4. Add key info: times, delays, inventory, handoffs
5. Highlight areas of waste or inefficiency
6. Brainstorm ways to streamline the process

You don’t need fancy software: a whiteboard or paper works just fine to start. You can map your processes digitally in Tervene, so your team can update and share improvements in real-time.

Once your team sees the process clearly, they’ll often suggest simple fixes right away. Over time, VSM helps you create smoother, faster, more efficient operations.

What is Kaizen, and how can you practice it daily? Continuous improvement tools

Kaizen means continuous improvement. It’s one of the core ideas behind lean manufacturing and one of the easiest to start using every day.

The basic concept is simple: You and your team look for small ways to improve the work, every day.

You don’t need big projects or fancy equipment. You focus on small changes that, over time, make a big impact.

Kaizen helps you build a continuous improvement culture, where everyone’s always looking for ways to do things better.

When you practice kaizen daily, you’ll:

• Solve problems faster
• Boost efficiency
• Make work easier and safer, reduce human error
• Engage your team in improvement
• Deliver better results for customers

Here are some easy ways to practice kaizen:

Activity	Example
Ask “What can we improve today?”	Morning team huddle
Identify a small change to test	Repositioning tools for better reach
Share one improvement with the team	Post on improvement board
Log ideas for future improvements	Kaizen notebook or Tervene app
Recognize team contributions	Quick shout-out in daily meeting

Also, you can use Tervene to track and share daily kaizen ideas, so improvements stay visible and momentum builds. And remember: it’s about steady progress, not perfection.

How can Kanban help you manage workflow?

Kanban is a simple, visual way to manage work. It helps you see what’s being done, what’s waiting, and what’s next, all at a glance.

The heart of Kanban lead methodology is visual scheduling. You use a board (physical or digital) with columns that show different stages of work, like To Do, In Progress, and Done. Each task is shown on a card that moves across the board as work progresses.

This makes the entire workflow visible to everyone. No guessing. No confusion. Pure lean productivity.

Kanban also helps you limit work-in-progress (WIP). This is key. When too much work is started at once, progress slows down. Employees get stuck multitasking or waiting. 

By setting WIP limits, you encourage the team to finish tasks before starting new ones. This keeps the flow steady and smooth. You’ll see improvements like:

• Faster delivery times
• Fewer bottlenecks
• Less stress for the team
• Higher quality results

Here’s how to start using Kanban:

1. Set up a simple board with key stages of your workflow
2. Add tasks as cards and move them as work progresses
3. Set WIP limits for “In Progress” work
4. Review the board regularly to spot and fix flow issues
5. Adjust your plan and improve as you go

Kanban helps you improve efficiency without adding complexity. And digital Kanban boards in Tervene can help you manage work visually, especially across multiple teams or locations. It’s flexible, easy to learn, and works for any team. 

Once you try it, you’ll wonder how you ever managed without it.

Standardize and structure lean manufacturing processes with Tervene’s tools

What is Poka-yoke and how does it prevent errors?

Poka-yoke means mistake-proofing. It’s a lean tool that helps you design processes so that it’s almost impossible to make certain types of errors.

Instead of fixing mistakes after they happen, poka-yoke helps you prevent them before they occur.

The idea is simple: build in checks, guides, or failsafes so that tasks can only be done the right way. This reduces defects, saves time, and improves quality, all without adding extra inspection work.

Here are a few common mistake-proofing techniques:

• Physical guides that ensure parts can only be installed the correct way
• Color coding to match components or materials
• Sensors that detect missing parts
• Alarms that alert operators when something’s out of place
• Fixtures that prevent incorrect assembly

You’ll see these in action in real factories every day:

• A jig that only holds a part if it’s oriented correctly
• A connector that only fits one way, avoiding cross-wiring
• Weight sensors that stop the line if a component is missing
• Assembly tools that won’t release unless torque is within spec

Poka-yoke doesn’t have to be high-tech. Often, the simplest solutions are the best.

When you use poka-yoke, you’ll:

• Cut down on rework
• Save time
• Improve safety
• Increase product quality for organizations

It’s one of the easiest ways to drive big improvements in reliability, and it’s a must-have tool in any lean environment.

How do you apply Just-in-time (JIT)?

Just-in-time (JIT) is all about producing only what’s needed (when it’s needed!) and in the right amount.

Instead of building up large stockpiles of parts or products, you produce items based on actual demand. This helps you avoid the costs and risks of excess inventory.

When you apply JIT, you’ll:

• Free up space
• Reduce inventory waste
• Cut storage costs
• Respond faster to changes in demand
• Improve cash flow

Here’s how to start using JIT:

Step	What to focus on
Understand demand	Analyze customer order patterns
Plan and align production with demand	Produce only what’s needed
Work with suppliers	Order smaller, more frequent batches
Shorten setup/changeover time	Reduce downtime between products
Use visual triggers	Kanban cards or digital signals

Remember: JIT as a lead methodology isn’t about cutting inventory to zero overnight. It’s about finding the right balance so you stay lean without running out.

Done well, JIT will help you work more efficiently, cut waste, and stay flexible in a fast-changing world.

What is Jidoka and why is built-in quality important?

Jidoka is a lean methodology that means “built-in quality.” The idea is simple: catch problems early (right when they happen), instead of finding them later.

When you detect defects early, you avoid passing bad work down the line. That saves time, cuts rework, and protects your customers from poor-quality products.

Jidoka also means empowering workers to stop production if they spot an issue. This is key. Instead of letting problems pile up, your team takes action right away.

When you build jidoka into your manufacturing process, you’ll:

• Improve product quality
• Reduce waste and rework
• Solve problems faster
• Build trust and ownership within your team

Here’s how you can apply jidoka:

• Install sensors that stop machines if a defect is detected
• Train workers to pause production if something looks wrong
• Design processes so it’s easy to spot problems (visual cues help)
• Encourage a “quality first” mindset, where stopping for quality is always supported

For example:

• On an assembly line, a worker pulls a cord (andon) to stop the line if a defect is found
• A machine automatically halts if a measurement goes out of tolerance
• Visual guides make incorrect parts or assemblies obvious

When you focus on built-in quality, you prevent issues instead of fixing them later. This leads to smoother operations and happier customers.

Jidoka is one of the best ways to create a culture of quality, and it works in any type of manufacturing.

How can standardized work bring lean productivity?

Standardized work is one of the most practical tools in lean manufacturing. It helps you make sure the best way of doing a job is captured, taught, and followed, every time.

At its core, it’s about documenting best practices. You take what works best (the safest, fastest, most reliable method) and write it down in a simple, clear format. This becomes the standard for how the work should be done.

When you have good standards in place, you’ll:

• Improve consistency
• Reduce mistakes
• Make training easier
• Support continuous improvement

Another key benefit is training for repeatability. With standardized work, new team members can quickly learn the right way to do the job. Experienced workers can stay sharp and consistent. Everyone knows what’s expected, which keeps quality high.

Here’s how to start using standardized work:

1. Watch how the best work is done. Talk with experienced team members
2. Write simple, clear instructions (with photos or diagrams if needed)
3. Train everyone using the same standards
4. Post the standards where the work happens; easy to see and use
5. Keep improving: update the standards when better ways are found

Tervene makes it easy to document standardized work and share updates instantly with your team If you want reliable results, day after day, standardized work with Tervene is a must.

What is takt time and how does it balance production?

Takt time is one of the simplest ways to bring balance to your production process. It helps you set the right pace, based on what your customers actually need.

The word takt comes from the German word for “rhythm” or “beat.” In lean terms, it means matching the pace of production to customer demand.

You figure out how often you need to produce a unit to meet demand, and then adjust your workflow to match that rhythm. Not too fast, not too slow.

When you work to takt time, you’ll:

• Reduce overproduction
• Avoid bottlenecks
• Keep production flowing smoothly
• Deliver on time

You’ll also be able to identify bottlenecks faster. If one step can’t keep up with takt time, that’s your signal to take action, maybe by improving flow, fixing equipment, or adding resources.

Here’s how to apply takt time:

1. Calculate takt time by dividing available production time by customer demand
2. Share that takt time with the team
3. Adjust the workflow to meet that pace
4. Monitor performance and flow, KPIs
5. Make improvements where needed to keep pace steady

For example, if customers need 240 units per shift, and you have 480 minutes to work, your takt time is 2 minutes per unit. Now the team knows exactly how fast each unit should move through the process.

Takt time helps you run lean, smooth, and in sync with your customers, which is exactly where you want to be.

How does Hoshin Kanri align your goals?

Hoshin Kanri is a simple but powerful way to connect strategy with daily work. It helps make sure everyone in the organization is moving in the same direction toward the goals that matter most.

Think of it like this: you’ve got big-picture objectives. But unless those goals shape what happens on the factory floor every day, they stay just words on paper. Hoshin kanri bridges that gap.

You’ll use it to:

• Translate long-term goals into clear, actionable plans
• Align teams across all levels
• Stay focused on priorities and your plan
• Track progress and adjust along the way

Here’s how it works in practice:

1. Define key goals (for the year, quarter, or longer)
2. Break those goals into smaller targets for departments and teams
3. Identify the actions needed to hit each target and KPIs
4. Communicate the plan clearly, so everyone knows their role
5. Check in regularly, review progress, and make adjustments

Hoshin Kanri helps you avoid scattershot efforts. You’ll focus energy where it counts, keep teams aligned, and make steady progress on your most important goals.

What is Heijunka and how does it smooth production flow?

Heijunka is all about leveling demand so your production runs smoothly, without the ups and downs that cause problems.

In most businesses, customer orders don’t come in a steady stream. Some days are busy. Some days are slow. If you try to match production exactly to those swings, it puts a lot of stress on your systems and your employees.

Heijunka helps you even things out. You plan and spread work more evenly over time, so you can handle demand without rushing or scrambling.

When you apply heijunka, you’ll:

• Reduce stress on systems and equipment
• Make workloads more balanced for your team
• Avoid last-minute firefighting
• Improve flow and efficiency, overall equipment effectiveness
• Deliver more consistently to customers

Here’s how to get started:

1. Collect data and analyze customer demand patterns
2. Break larger orders into smaller, regular batches
3. Build a mixed schedule: producing different products in small batches across the day or week
4. Adjust setup processes so switching between products is easy
5. Monitor and fine-tune the schedule as demand shifts

For example, instead of producing 1,000 units of Product A one week and 1,000 units of Product B the next, you’d produce a smaller mix of both products each day.

This steady rhythm reduces stress on your systems and makes it easier to keep quality high. Over time, you’ll see smoother production, happier teams, and more reliable delivery to customers.

How can Total Productive Maintenance (TPM) reduce downtime?

Total productive maintenance helps you keep equipment running smoothly, so you can avoid unplanned downtime.

The key idea is simple: involve everyone in equipment care, not just the maintenance team. Operators, supervisors, and maintenance staff all work together to keep machines in top shape.

Instead of waiting for things to break, you take a proactive approach. You spot issues early, handle small problems before they turn into big ones, and keep everything running at peak performance.

When you apply TPM, you’ll:

• Reduce unplanned downtime
• Extend equipment life
• Maximize asset efficiency
• Improve safety
• Boost product quality

Here’s how to get started:

1. Train operators to handle basic maintenance (cleaning, inspection, lubrication)
2. Create simple daily checklists with KPIs
3. Encourage teams to report small problems right away
4. Schedule regular preventive maintenance
5. Track equipment performance to spot trends
6. Celebrate wins, because every improvement helps

By involving everyone in equipment care, you’ll build a culture of shared responsibility. Machines won’t just “belong” to maintenance anymore: the whole team will help keep them running well.

When equipment runs reliably, everything else gets easier. You’ll see smoother flow, fewer delays, and better results across the board.

TPM is one of the most practical ways to maximize asset efficiency and a must-have for any lean manufacturing environment.

With so many lean tools out there, it can feel a little overwhelming at first. But you don’t have to master everything at once. The key is to start where it matters most.

First, take time to assess your current processes. Walk the floor. Talk to your team. Look at where problems tend to pop up. Maybe it’s downtime, quality issues, or inventory piling up. This gives you a clearer picture of where lean tools can help.

Next, look for quick wins. Which tools could give you fast, visible improvements? Small wins build momentum and get your team engaged.

For example, if the workplace is disorganized, start with 5S. If flow is slow, try value stream mapping. If quality is inconsistent, look at poka-yoke or standardized work.

At the same time, make sure you’re aligning with business goals. What’s most important right now: cutting costs, improving delivery, boosting quality? Choose tools that will help you get there.

Here’s a simple way to decide:

1. Assess where the biggest problems or opportunities are
2. Identify tools that can deliver quick wins
3. Prioritize tools that align with key business goals
4. Start small and master one tool at a time
5. Build on your success and expand from there

You’ll learn faster, get better results, and keep your lean journey moving forward, step by step. And tools like Tervene can really help here, giving you one place to manage lean tools and track progress.

Learning lean tools is a great start, but the real value comes when you put them into action. And remember: mastering lean tools is a journey. You don’t have to do everything at once.

Start with what makes sense for you. Look at your current challenges. Choose one or two tools that can help right away. Build from there.

As you go, you’ll discover that small, consistent efforts lead to big results. Every plan and improvement, no matter how small, moves you closer to your goals.

And don’t be afraid to bring technology into the mix. Digital lean tools can really help, making it easier to track progress, share information, and stay on top of improvement efforts.
