The ultimate goal is embedding organized practices into daily work culture, making excellence the default operating mode rather than an occasional achievement.
5S Standardize (Seiketsu) - Complete Guide for Six Sigma Green Belt
What is 5S Standardize (Seiketsu)?
Seiketsu, the fourth pillar of the 5S methodology, translates to Standardize in English. It refers to the process of creating consistent procedures, visual controls, and documented standards to maintain the improvements achieved through the first three S's: Sort (Seiri), Set in Order (Seiton), and Shine (Seiso).
Standardize ensures that the organized and clean workplace becomes the norm rather than a one-time achievement. It establishes the new baseline for how work areas should look and function on a daily basis.
Why is Standardize (Seiketsu) Important?
• Prevents regression: Maintains the gains from Sort, Set in Order, and Shine activities • Creates consistency: Ensures all team members follow the same procedures • Reduces variation: Minimizes process variability by establishing clear expectations • Enables visual management: Makes abnormalities visible so problems can be addressed quickly • Supports training: Provides documented procedures for onboarding new employees • Builds accountability: Assigns clear responsibilities for maintaining workplace organization
How Does Standardize Work?
Step 1: Document Best Practices Create written procedures, checklists, and guidelines that capture the optimal state achieved through the first three S's.
Step 2: Develop Visual Standards Use photos, color coding, floor markings, shadow boards, and labels to make the correct state obvious to everyone.
Step 3: Create Schedules and Checklists Establish cleaning schedules, inspection checklists, and maintenance routines with assigned responsibilities.
Step 4: Assign Ownership Designate specific individuals or teams responsible for maintaining each area or process.
Step 5: Train All Personnel Ensure everyone understands the standards and knows their role in maintaining them.
Key Tools Used in Standardize
• Visual workplace standards (reference photos) • 5S audit checklists • Color-coded systems • Shadow boards for tools • Standard Operating Procedures (SOPs) • Zone maps with assigned owners • Cleaning and maintenance schedules
Exam Tips: Answering Questions on 5S Standardize (Seiketsu)
1. Remember the sequence: Standardize is the fourth S and builds upon Sort, Set in Order, and Shine. Questions may test your understanding of the logical order.
2. Focus on sustainability: When you see answer choices, look for options that emphasize maintaining and sustaining improvements rather than making new ones.
3. Visual management is key: Standardize heavily relies on visual controls. If a question asks about making standards visible or obvious, this relates to Seiketsu.
4. Documentation matters: Correct answers often involve creating procedures, checklists, or documented standards.
5. Differentiate from Sustain: Standardize creates the rules and visual standards; Sustain (Shitsuke) is about the discipline to follow them. This is a common exam trap.
6. Look for accountability: Assigning responsibility and ownership of areas is a Standardize activity.
7. Common question types: • Identifying which S addresses creating visual workplace standards • Selecting tools associated with Standardize • Ordering the 5S steps correctly • Distinguishing between Standardize and Sustain activities
8. Key phrases to recognize: When exam questions mention documented procedures, visual standards, checklists, assigned responsibilities, or consistent methods, think Standardize.
