The 5S process is to daily execution what eating a healthy breakfast and exercising is to your health. Do it consistently every day and it will change your life.
5S can be applied to your kitchen, garage, service van, work truck, gang box, storage container, desk, computer, warehouse, etc. Wherever your personal work area is you can apply 5S.
If you do it once as if it were a major project then it won’t do anything besides put you behind schedule.
If a 600 calorie breakfast + 30 minutes of stretching and exercise is a good morning routine then you would never say:
“Once per month I’ll workout for 15 hours and eat 18,000 calories so I can save time all month”
Make 5S a habit for yourself. Engage your team. Align the times when you do your 5S. Share your results - good and bad. Try it for a year and see what happens.
