A workplace organisation system designed to improve efficiency, safety, and workflow in warehouses. It consists of five steps:

1. Sort – Remove unnecessary items.

2. Set in Order – Arrange items for easy access.

3. Shine – Clean the workspace regularly.

4. Standardise – Establish consistent procedures.

5. Sustain – Maintain and review standards continuously.

Applying 5S helps reduce waste, prevent errors, and create a more productive and organised fulfilment environment.

The Five S's Explained

1. Sort (Seiri - 整理)

Remove everything that's not needed for current operations.

The Problem: Warehouses accumulate stuff. Old packaging materials, broken equipment, obsolete inventory, unused pallets, redundant paperwork. This clutter:

• Wastes space

• Slows down work (searching through irrelevant items)

• Creates safety hazards

• Hides problems

The Solution: Systematic sorting process:

Red Tag Method: Place red tags on anything questionable. If not used within 30 days, remove from the operational area.

Categories:

• Keep: Used regularly, needed for operations

• Store: Needed but infrequently, move to designated storage

• Dispose: Broken, obsolete, or unnecessary - remove entirely

Example: A packing station audit reveals:

• 3 types of tape (only need 1)

• 2 broken scissors

• Packaging materials for discontinued products

• Old carrier labels from the previous system

• 4 pens (2 don't work)

Sort step: Keep one tape dispenser, scissors, and current materials. Remove everything else.

Business Impact:

• Reclaim 10-15% space typically

• Reduce search time

• Identify inventory for disposal or return

• Clear mental clutter

2. Set in Order (Seiton - 整頓)

Arrange everything for maximum efficiency and accessibility.

The Principle: "A place for everything, and everything in its place."

Implementation:

Visual Management:

• Shadow boards showing tool outlines

• Colour coding for different functions

• Floor markings for designated areas

• Clear labelling of all locations

Ergonomic Placement:

• Most-used items at waist height

• Heavy items at knee height (leverage for lifting)

• Infrequent items are higher or lower

• Point-of-use placement (tools where needed)

Logical Flow: Arrange workspace to match work sequence. If the process is receive → check → label → store, the layout should reflect that flow.

Example: Packing station redesign:

• Tape dispenser mounted at hand level

• Most common box sizes within arm's reach

• Labels printer positioned for natural workflow

• Waste bin directly below the workspace

• Packing materials organised by usage frequency

Result: 30% faster packing from reduced motion waste.

Connection to Warehouse Layout: Set in Order principles scale from workstations to entire warehouses. ABC Analysis-based slotting is Set in Order applied to inventory locations.

3. Shine (Seiso - 清掃)

Clean workspace regularly and maintain equipment.

Beyond Basic Cleaning: Shine isn't just about appearance - it's about inspection and maintenance through cleaning.

When you clean, you discover:

• Equipment wear or damage

• Leaks or spills (safety hazards)

• Missing items or misplaced stock

• Process problems (why does this area get so dirty?)

Implementation:

Daily Cleaning:

• Each team member is responsible for their area

• 10-15 minutes at shift end

• Immediate cleanup of spills or damage

Weekly Deep Clean:

• Thorough equipment inspection

• Floor cleaning and maintenance

• Racking and storage area inspection

• Safety equipment checks

Monthly Comprehensive:

• Major equipment servicing

• Complete facility inspection

• Address accumulated issues

• Review and update cleaning procedures

Equipment Maintenance: Regular cleaning maintains equipment performance:

• Scanners work reliably when clean

• Printers avoid paper jams

• Forklifts operate safely

• Conveyors run smoothly

Example: A picker discovers during daily shine that the scanner is intermittently failing. Quick cleaning and inspection reveal a damaged cable. Immediate replacement prevents a day of lost productivity from scanner failure.

4. Standardise (Seiketsu - 清潔)

Create consistent procedures that everyone follows.

The Challenge: Everyone has their own way of doing things. This creates:

• Inconsistent quality

• Training difficulties

• Communication problems

• Impossible to improve (which method do you improve?)

The Solution: Document and implement best practices as standard.

What to Standardise:

Workplace Organisation:

• Standard locations for tools and materials

• Consistent labelling systems

• Uniform storage methods

• Common cleaning procedures

Work Processes:

• Standard operating procedures for key tasks

• Documented pick paths

• Consistent packing methods

• Uniform quality checks

Visual Standards:

• Photos showing the correct setup

• Diagrams for proper arrangement

• Checklists for daily tasks

• Performance standards visible

Implementation:

Document Best Practices: Identify the most efficient methods currently used and make them standard for everyone.

Visual Management: Create visual guides, making standards obvious:

• "Before and After" photos showing the correct setup

• Shadow boards showing tool placement

• Floor markings indicating proper positioning

• Colour coding for different categories

Training: Train all staff to follow standards, not "do it your own way."

Audit and Feedback: Regular checks ensure standards are followed, with constructive feedback when deviations occur.

Example: Three pickers use different methods. Picker A is the fastest and most accurate. Document Picker A's method as standard, train B and C. Result: Overall team productivity increases 15% and accuracy improves.

This connects directly to LEAN principles of reducing variation.

5. Sustain (Shitsuke - 躾)

Maintain improvements through discipline and culture.

The Hard Part: Most 5S implementations start strong, then fade. Enthusiasm wanes, standards slip, old habits return.

Why Sustain Fails:

• No accountability for maintaining standards

• No regular audits or reviews

• Success not celebrated

• Problems not addressed promptly

• Management doesn't model behaviour

How to Sustain Successfully:

Leadership Commitment: Management must visibly support 5S:

• Participate in audits

• Recognise good practices

• Address issues quickly

• Provide resources

• Model expected behaviours

Regular Audits: Scheduled checks (weekly/monthly) assessing 5S adherence:

• Formal scoring system

• Results posted visibly

• Trends tracked over time

• Recognition for high scores

• Support for areas needing improvement

Continuous Improvement: 5S isn't static - continuously refine:

• Regular reviews asking "Can this be better?"

• Implement team suggestions

• Share successes across areas

• Update standards as processes improve

Integration with Daily Work: Make 5S part of normal operations, not an "extra" activity:

• 10-15 minute daily shine time built into schedules

• Set in Order checks during shift handovers

• Sort activities during quiet periods

• Standardisation reviews in team meetings

Example: The operation implements monthly 5S audits with visible scoring. Areas scoring 90%+ get recognition. Areas below 70% get support and improvement plans. After 6 months, the average score rises from 65% to 87%, and it stays there because it's embedded in culture.

Frequently Asked Questions

How long does 5S implementation take?

Pilot area: 4-8 weeks to initial implementation. Entire facility: 6-12 months for thorough rollout. Sustaining: Ongoing forever; 5S is a permanent way of working.

Do we need consultants?

Not necessarily. Many operations successfully implement 5S using internal resources and free guides. Consultants can accelerate learning, but aren't essential.

What if our team resists 5S?

Resistance usually stems from poor communication or fear of criticism. Involve them in design, explain benefits clearly, celebrate small wins, and show how 5S makes their jobs easier.

Can we do 5S alongside technology improvements?

Yes. 5S complements WMS implementations perfectly. Clean, organised warehouses help technology work better.

How do we maintain 5S long-term?

Regular audits, visible accountability, prompt issue resolution, continuous recognition, leadership commitment, and integration with daily operations. Make it culture, not a program.
