The term 'Seiri' comes from Japanese and translates to 'Sort' or 'Organize.' This phase focuses on separating necessary items from unnecessary ones in a workspace, then removing what is not needed for current operations.
During the Define Phase of a Lean Six Sigma project, implementing Sort helps teams establish a clear baseline of their work environment. The process involves systematically evaluating every item in a workspace - including tools, materials, equipment, documents, and supplies - to determine their value and frequency of use.
The Sort process typically follows these steps: First, team members identify all items in the designated area. Second, each item is evaluated using criteria such as frequency of use, necessity for current tasks, and overall value to operations. Third, items are categorized into groups: keep, relocate, dispose, or undetermined. Items that haven't been used for extended periods or serve no clear purpose are candidates for removal.
A popular technique used during Sort is the 'Red Tag' method, where questionable items receive red tags indicating they need further evaluation. These tagged items are moved to a holding area where decisions about their fate can be made over a specified timeframe.
The benefits of Sort include reduced clutter, improved safety, better space utilization, and enhanced productivity. By eliminating unnecessary items, employees can locate needed tools and materials more efficiently, reducing wasted time and motion.
In the Define Phase context, Sort helps project teams understand current state conditions and identify potential areas of waste. This creates a foundation for subsequent 5S steps: Set in Order, Shine, Standardize, and Sustain, ultimately contributing to a more streamlined and effective work environment.

What is 5S Sort (Seiri)?
Seiri, or Sort, is the first step in the 5S methodology, a Japanese workplace organization system. The term 'Seiri' translates to 'tidiness' or 'organization.' This step involves systematically separating necessary items from unnecessary items in the workplace and removing everything that is not required for current operations.
Why is 5S Sort (Seiri) Important?
Sort is crucial for several reasons:
• Eliminates waste: Removing unnecessary items reduces clutter and frees up valuable workspace • Improves efficiency: Workers spend less time searching for tools and materials • Reduces costs: Prevents duplicate purchases and reduces storage requirements • Enhances safety: Fewer obstacles mean reduced risk of accidents • Creates foundation: Sort establishes the groundwork for the remaining 4S steps • Improves morale: A cleaner workspace leads to better employee satisfaction
How Does 5S Sort (Seiri) Work?
The Sort process follows a systematic approach:
Step 1: Identify the Target Area Select a specific workspace, department, or area to organize.
Step 2: Evaluate All Items Examine every item in the area and categorize them based on necessity and frequency of use.
Step 3: Red Tag Strategy This is the most common technique used in Sort. Items are tagged with red labels indicating: • Item name and description • Quantity • Reason for tagging • Date tagged • Disposition decision
Step 4: Classification Categories Items are sorted into three main categories: • Keep: Items used regularly and essential for operations • Relocate: Items used occasionally that should be stored elsewhere • Dispose: Items that are broken, obsolete, or unnecessary
Step 5: Take Action Execute the disposition plan by removing, relocating, or properly storing items.
Key Tools and Techniques
• Red Tag Holding Area: A designated space where tagged items await final disposition • Frequency of Use Matrix: Helps determine where items should be stored based on how often they are used • Before and After Photos: Document improvements for training and motivation
Exam Tips: Answering Questions on 5S Sort (Seiri)
Tip 1: Remember the Core Purpose Sort is about separating necessary from unnecessary items. Questions often test whether you understand this fundamental concept.
Tip 2: Know the Red Tag Process Exams frequently ask about the red tag strategy. Remember that red tags are temporary markers used during the sorting process to identify items for review.
Tip 3: Understand the Sequence Sort is always the first step in 5S. Questions may ask about the order of implementation.
Tip 4: Recognize Common Scenarios Look for questions describing cluttered workspaces or situations where workers cannot find tools - these typically point to Sort as the solution.
Tip 5: Differentiate from Other S's Be careful not to confuse Sort with Set in Order (Seiton). Sort removes unnecessary items; Set in Order organizes what remains.
Tip 6: Focus on Benefits Questions may ask about outcomes of implementing Sort. Key benefits include reduced search time, freed-up space, and waste elimination.
Tip 7: Watch for Keywords Terms like 'red tag,' 'necessary vs unnecessary,' 'remove,' 'eliminate,' and 'categorize' often indicate Sort-related questions.
Common Exam Question Types
• Multiple choice asking to identify the first step of 5S • Scenario-based questions about workplace clutter • Questions about the red tag process and its components • True/false questions about Sort objectives • Questions comparing Sort to other 5S steps
