What Are the 7S of Manufacturing? A Practical Guide to Workplace Efficiency

If you’ve ever walked into a factory and felt like everything was just barely holding together - tools scattered, labels peeling off bins, machines covered in dust - you’ve seen what happens when the 7S of manufacturing are ignored. This isn’t about fancy tech or big budgets. It’s about the quiet, daily habits that turn chaos into control. The 7S system isn’t new, but it’s still the most reliable way small and mid-sized manufacturers cut waste, boost safety, and keep production running smoothly. And yes, it works whether you’re making steel parts, pharmaceuticals, or plastic containers.

What Exactly Are the 7S of Manufacturing?

The 7S methodology is a workplace organization system that grew out of Japan’s lean manufacturing movement. It’s an expanded version of the original 5S, with two extra elements added to make it more practical for modern production environments. Each S stands for a Japanese word, but you don’t need to learn Japanese to use it. Here’s what they mean in plain English:

• Sort - Get rid of what you don’t need.
• Set in Order - Put everything where it belongs.
• Shine - Clean as you go.
• Standardize - Make it consistent.
• Sustain - Keep it up.
• Safety - Protect people and equipment.
• Save - Cut waste in time, materials, and energy.

Notice that Safety and Save are the two additions. Many companies still use just 5S, but in today’s environment - with rising energy costs, stricter regulations, and worker shortages - those last two make all the difference.

Sort: Stop Hoarding and Start Clearing

Every factory has a corner where broken tools, old manuals, and unused parts go to die. That’s not storage - that’s clutter. Sorting means asking one simple question: Has this been used in the last 30 days? If not, it’s taking up space that could be used for something that actually moves production forward.

One small electronics manufacturer in Victoria sorted their tool crib and found 147 screwdrivers - 112 of them were identical, broken, or missing tips. They threw out 90, donated 15, and kept only 42 that were actually usable. That freed up 12 square meters of floor space. They used it for a new quality inspection station. Output went up 18% in three months.

Use red tags. Put them on anything questionable. Give teams 48 hours to respond. If no one claims it, toss it or recycle it. This isn’t harsh - it’s honest. Clutter hides problems. When you remove it, you see what’s really going on.

Set in Order: Design for Flow, Not Convenience

It’s not enough to just put tools in a drawer. Set in Order means arranging everything so the worker doesn’t have to think. The most-used items should be within arm’s reach. The heaviest tools should be at waist height. Labels aren’t optional - they’re essential.

A food processing plant in South Australia used shadow boards for their cleaning tools. Each brush, scraper, and hose has a shaped outline on the wall. If something’s missing, you know immediately. No more searching. No more delays during sanitation checks. Their compliance audit score jumped from 72% to 98% in six weeks.

Use floor markings, color-coded zones, and visual cues. If a worker can’t find what they need in three seconds, it’s not organized. It’s a guessing game - and guessing causes errors.

Shine: Cleanliness Isn’t Just for Show

Shine doesn’t mean making the floor sparkle. It means cleaning daily - not just when the boss walks by. Dust, oil leaks, and debris aren’t just ugly. They’re dangerous. Slippery floors cause falls. Grease on belts causes breakdowns. Dirt in bearings causes premature wear.

One steel fabrication shop started assigning 15 minutes of cleaning time at the start and end of every shift. Workers cleaned their own workstations. Within four months, machine downtime dropped by 31%. Why? Because they caught oil leaks early. They saw cracks in guards before they failed. They noticed worn cables before they sparked.

Shine turns maintenance from a reactive chore into a proactive habit. When you clean, you connect with your equipment. You start noticing things you never saw before.

Standardize: Turn Good Habits Into Rules

Sorting, setting, and shining work great for a week. But without standards, they fade. Standardize means writing down exactly how things should be done - and making sure everyone follows it.

Use photos. Take pictures of a perfectly organized tool rack, a clean workstation, a properly labeled bin. Print them. Laminate them. Put them on the wall next to the area they describe. Add simple instructions: “All wrenches here. No exceptions.”

One pharmaceutical manufacturer in New South Wales created a 7S checklist for each production line. Supervisors sign off daily. Workers sign off weekly. Audits happen monthly. They didn’t hire a consultant. They didn’t buy software. They just made it visible and accountable.

Standardization isn’t about control. It’s about consistency. When everyone knows the rules, you don’t need to micromanage.

Sustain: Make It Part of the Culture

This is where most companies fail. They do a big 7S blitz in January. Take photos. Celebrate. Then everything slips back by March.

Sustain means making 7S part of how you work - not something you do once a year. That means:

• Start every shift with a 5-minute 7S check.
• Include 7S in new employee onboarding.
• Recognize teams who keep their area clean and organized.
• Make it part of performance reviews.

A furniture maker in Queensland started a “7S Champion” program. Each month, a different worker leads the review of their line. They pick the winner based on photos, feedback, and audit scores. The winner gets a parking spot closer to the door. It sounds small. But people started caring. Morale improved. Defects dropped.

Sustainability isn’t about rules. It’s about ownership. When workers feel responsible, they protect the system.

Safety: The Most Important S

Every accident starts with a small oversight. A frayed cord. A blocked exit. A missing guard. Safety isn’t just a policy - it’s built into how you organize your space.

After sorting, ask: Is there anything here that could hurt someone? After setting in order, ask: Can someone move freely without tripping or bumping into something? Shine reveals hidden hazards. Standardize ensures they’re fixed. Sustain keeps them fixed.

One chemical plant in Western Australia used 7S to fix a recurring spill issue. They realized the problem wasn’t human error - it was poor layout. The valve controls were behind a stack of empty drums. Workers had to reach over them. One slip, and a 20-liter drum tipped. They moved the drums, added a secondary containment tray, and marked the path with yellow tape. No more spills in 18 months.

Safety isn’t about helmets and signs. It’s about smart design.

Save: Efficiency Is Profit

Save is the newest addition to the 7S system - and the most powerful. It’s not just about saving money. It’s about saving time, energy, materials, and effort.

After implementing 7S, most manufacturers find:

• 20-40% less time spent searching for tools
• 15-30% reduction in material waste
• 10-25% lower energy use from better equipment maintenance
• Fewer overtime hours because production flows smoother

A plastic injection molding company in Adelaide tracked their energy use before and after 7S. They found machines were left on overnight because no one knew who was responsible. They added a simple “Power Off” checklist. Energy costs dropped 19% in one quarter. That’s $18,000 a year saved on a single line.

Save isn’t about cutting corners. It’s about removing friction. Every wasted movement, every misplaced part, every idle machine - that’s money leaking out.

How to Start With 7S - Even If You’re Overwhelmed

You don’t need to fix everything at once. Pick one production line. Pick one shift. Start small.

1. Choose a small area - maybe a tool bench or a packing station.
2. Hold a 30-minute team meeting. Ask: What’s the biggest frustration here?
3. Do a 1-hour Sort. Use red tags. Remove everything non-essential.
4. Set in Order. Put tools back where they’re used.
5. Shine. Clean everything.
6. Take a photo. Make a sign. Standardize.
7. Do this every day for a week.
8. Then expand to the next area.

Don’t wait for perfect. Start messy. Just start.

Why 7S Beats Other Systems

There are dozens of manufacturing improvement methods - Six Sigma, Kaizen, TPM. They’re all good. But they’re complex. They need consultants, software, training programs.

7S is different. It needs no software. No certifications. No expensive tools. Just people, time, and a willingness to look at your workspace differently. It’s the only system that turns cleaning into a strategy.

And it works. A 2024 study by the Australian Manufacturing Technology Institute found companies using 7S saw an average 27% increase in on-time delivery and a 34% drop in workplace injuries over 12 months. No other method had such broad, measurable impact with so little investment.

Final Thought: It’s Not About the S’s - It’s About the Mindset

The 7S of manufacturing isn’t a checklist. It’s a way of thinking. It’s asking: Why is this here? Why does it have to be this way? Can we do better?

When workers start asking those questions, change happens. Not because someone told them to. But because they saw a better way - and they wanted it.
