In the continuous journey towards operational excellence, the Improve phase of the DMAIC methodology stands as a critical juncture where organizations transform insights into action. Among the most powerful tools available during this phase is the 5S workplace organisation system, a methodology that has revolutionized manufacturing floors, offices, and service environments worldwide. This systematic approach to workplace organisation not only enhances efficiency but also creates a foundation for sustainable improvement and cultural transformation.
Understanding 5S Within the Improve Phase Context
The Improve phase in Lean Six Sigma represents the transition from analysis to implementation. After identifying root causes and developing potential solutions, teams must execute changes that will eliminate defects, reduce variation, and optimize processes. The 5S methodology serves as an excellent starting point because it addresses the fundamental aspect of workplace organisation while simultaneously building momentum for larger improvements.

The 5S system comprises five Japanese terms: Seiri (Sort), Seiton (Set in Order), Seiso (Shine), Seiketsu (Standardize), and Shitsuke (Sustain). Each component builds upon the previous one, creating a comprehensive framework that transforms chaotic work environments into efficient, standardized spaces where waste is minimized and productivity flourishes.

The Five Pillars of Workplace Organisation
Sort: Eliminating the Unnecessary
The first S begins with a critical evaluation of every item in the workplace. The objective is to distinguish between necessary and unnecessary items, removing anything that does not add value to current operations. This process requires discipline and often challenges long-held beliefs about what might be needed “someday.”
Consider a practical example from a manufacturing facility producing electronic components. Before implementing Sort, the assembly area contained 47 different types of tools, of which only 23 were used regularly. The team discovered 156 obsolete components stored in workstation drawers, consuming valuable space. Through systematic sorting, they removed 24 unused tools and all obsolete components, freeing up approximately 35% of storage space.
The sorting process typically employs red tagging, where questionable items receive red tags and are moved to a holding area for a predetermined period. If no one claims or uses these items within that timeframe, they are disposed of, sold, or relocated to more appropriate storage areas.
Set in Order: A Place for Everything
Once unnecessary items are removed, the second S focuses on organizing remaining items for optimal efficiency. This involves designating specific locations for tools, materials, and equipment based on frequency of use and workflow patterns. The guiding principle is that anyone should be able to locate what they need within 30 seconds.
In a hospital pharmacy case study, staff members were spending an average of 8.5 minutes per shift searching for specific medications. After implementing Set in Order principles, they created a standardized storage system with clearly labeled zones organized by medication type and usage frequency. High-use medications were placed at waist level within arm’s reach, while less frequently used items were stored higher or lower. This reorganization reduced search time to an average of 1.2 minutes per shift, saving approximately 61 staff hours per month.
Visual management tools such as shadow boards, color coding, and floor markings play crucial roles during this phase. These visual cues eliminate ambiguity and ensure that everyone understands where items belong.
Shine: Cleaning as Inspection
The third S transforms cleaning from a periodic chore into a daily discipline and inspection opportunity. Regular cleaning allows workers to identify abnormalities such as leaks, cracks, misalignments, or wear patterns before they escalate into significant problems.
A food processing plant implemented Shine by allocating the last 15 minutes of each shift to cleaning and inspection activities. Within three months, this practice led to the early detection of 23 equipment issues that could have caused production downtime. Maintenance records showed a 42% reduction in unplanned equipment failures, and production uptime increased from 87% to 94%.
The Shine phase establishes cleaning schedules, assigns responsibilities, and provides appropriate cleaning supplies and equipment. It emphasizes that cleaning is everyone’s responsibility, not just the custodial staff.
Standardize: Creating Consistency
The fourth S involves developing standards and procedures that maintain the gains achieved through the first three S’s. Standardization ensures that Sort, Set in Order, and Shine practices become routine rather than one-time events.
Organizations create visual standards through photographs, diagrams, and checklists that clearly illustrate how work areas should appear. These standards become reference points for daily operations and training new employees.
An automotive parts supplier developed a standardization system using photographic documentation of ideal workstation configurations. Each workstation had a posted reference photo showing exact tool placement, material locations, and cleanliness expectations. Monthly audits comparing actual conditions to these standards revealed compliance rates improving from 68% in the first month to 96% after six months of consistent implementation.
Sustain: Building a Culture of Discipline
The final S represents the most challenging aspect of 5S implementation: maintaining improvements over time. Sustain requires leadership commitment, regular audits, visible metrics, and recognition systems that reinforce desired behaviors.
Successful sustain efforts incorporate several key elements. Regular 5S audits, typically conducted weekly or monthly, assess compliance with established standards. Results are posted publicly, creating transparency and accountability. Recognition programs celebrate teams that consistently maintain high standards, while also providing support and additional training for those struggling with compliance.
A logistics company tracking 5S sustainability over 18 months found that areas with weekly audits and visible score displays maintained compliance above 90%, while areas without structured monitoring fell to 72% compliance. This data underscores the importance of systematic oversight in sustaining improvements.
Implementing 5S: A Structured Approach
Preparation and Planning
Successful 5S implementation begins with thorough preparation. Organizations should establish a steering committee, select pilot areas, develop training materials, and create measurement systems. Setting realistic timelines prevents rushed implementation that might undermine long-term success.
Training and Communication
Every person affected by 5S must understand not just the “how” but also the “why” behind the methodology. Training sessions should include hands-on activities, workplace tours of successful implementations, and opportunities for questions and concerns. Leadership participation in training signals organizational commitment and importance.
Pilot Implementation
Starting with pilot areas allows organizations to refine approaches, identify challenges, and generate success stories that build momentum for broader deployment. Pilot areas should be visible and manageable in scope, typically completed within 30 to 60 days.
Expansion and Integration
After validating the approach through pilot implementations, organizations systematically expand 5S across additional areas. Each new implementation benefits from lessons learned previously, and success stories from early adopters help overcome resistance in new areas.
Measuring 5S Success
Quantifying 5S impact provides evidence of value and maintains organizational support. Key metrics include search time reduction, inventory accuracy improvements, safety incident decreases, and productivity increases. Before and after photographs provide powerful visual evidence of transformation.
Organizations should establish baseline measurements before implementation and track progress regularly. Typical metrics show search time reductions of 50% to 80%, inventory accuracy improvements of 15% to 30%, and productivity gains of 10% to 25%.
Common Challenges and Solutions
Resistance to change represents the most significant implementation barrier. Employees may view 5S as additional work or question its relevance. Addressing this requires consistent communication about benefits, involvement in planning, and recognition of participation.
Maintaining momentum after initial enthusiasm wanes challenges many organizations. Regular audits, visible metrics, leadership engagement, and continuous improvement of 5S practices itself help sustain long-term commitment.
The Broader Impact of 5S
Beyond immediate operational benefits, 5S creates cultural shifts that enable further improvement initiatives. Organizations with strong 5S foundations find subsequent Lean Six Sigma projects easier to implement because employees have already developed discipline, standardization mindset, and comfort with change.
The methodology also enhances safety, improves quality, boosts employee morale, and creates better impressions for customers and visitors. These intangible benefits often exceed the measurable operational gains.
Taking Your Improvement Journey Further
While 5S provides an excellent foundation for workplace improvement, it represents just one tool within the comprehensive Lean Six Sigma methodology. Understanding how 5S integrates with other improvement tools, when to apply different methodologies, and how to lead successful improvement initiatives requires structured learning and practice.
