5S in Practice: A Field Checklist You Can Use This Week
5S is a Lean workplace organisation methodology that consists of five steps: Sort (eliminate what is not needed), Set in Order (organise what remains so everything has a place and everything is in its place), Shine (clean the workplace and keep it clean), Standardise (document the standard and make deviations visible), and Sustain (maintain the standard over time through discipline and habit). 5S creates the physical and organisational conditions for safer, more efficient, and more consistent work. It is often the first Lean tool deployed in a new improvement initiative because a disorganised workplace prevents almost every other improvement.
Sort Checklist
Walk the area with a critical eye and identify every item that is not necessary for current work. Apply the Red Tag method: attach a red tag to every item you are not certain is necessary. Set a decision period (typically two to four weeks) during which anyone who needs a red-tagged item removes the tag and documents why. Items that remain tagged at the end of the period are removed.
Apply Sort to everything: tools, equipment, supplies, documents, files, and furniture. The goal is to have only what is currently needed present in the work area.
Dispose of red-tagged items appropriately: return to store, transfer to another area that needs them, or scrap. Do not simply move clutter to another location.
Set in Order Checklist
Assign a fixed location to every item that passed the Sort step. The location should reflect frequency of use (frequently used items closest to the point of use) and logical workflow.
Make locations visual: labels, shadow boards, floor markings, colour coding. A shadow board with outlines of each tool makes missing items immediately visible.
Apply the 30-second rule: a worker should be able to retrieve any item and return it to its designated location within 30 seconds without searching.
Shine Checklist
Clean the area thoroughly -- floors, equipment, surfaces, and storage areas. Cleaning is also an inspection: defects, leaks, and damage are often found during the cleaning process.
Identify and address the sources of contamination and disorder, not just their effects. If a machine leaks oil, fix the leak rather than cleaning the floor repeatedly.
Assign cleaning responsibilities by area and task, and document the cleaning schedule.
Standardise and Sustain Checklist
Document the standard: photographs of the correct state of each area, cleaning schedules, and storage location maps. Standards that are not documented cannot be sustained.
Conduct regular 5S audits. A simple scoring checklist (1-5 for each S, with criteria) makes the audit objective and trackable over time.
Make 5S a routine, not an event. A 5-minute 5S check at the beginning or end of each shift is more effective than a quarterly deep clean.
Recognise and reinforce good 5S practice. Sustaining 5S requires positive reinforcement, not just correction of non-compliance.
