Sort, set in order, shine, standardise, sustain: a tidy, visible workplace where problems cannot hide.

5S sounds like housekeeping, and in a sense it is. Its purpose is deeper: when everything has a place and the normal state is obvious, anything abnormal jumps out. A missing tool, an overflowing tray or a stalled job is seen at a glance instead of discovered at the end of the day.
A finance team loses ten minutes several times a day hunting for the latest version of a spreadsheet in a shared drive with eleven years of folders. They archive everything untouched for two years, agree five top-level folders, adopt one naming rule with dates written year first, and pin a one-page guide to the drive.
Three months later a short audit finds the rule mostly kept, with one folder sliding. That folder gets an owner. The minutes saved are not glamorous, yet across a team of eight they add up to a day a week.
