Before you read anything - play the game below. It takes about 5 minutes. You will understand 5S better from playing four rounds than from reading five pages.
That feeling in round three - moving faster, thinking less, just finding the next number - that is 5S. Now let me tell you where it comes from.
It started on a Toyota factory floor, 70 years ago. Five Japanese words: Seiri, Seiton, Seiso, Seiketsu, Shitsuke - Sort, Set in Order, Shine, Standardize, Sustain. Every tool has a home. Every home has a label. Nobody wastes a motion searching.
Your laptop is a factory floor. Your tools are apps, files, and notifications. Right now, most of them are scattered, unlabeled, and piling up.
I have lived on both sides of this. At Jabil Circuit in Poughkeepsie, I managed engineering for a team building IBM mainframes on a 180,000 square foot production floor. Our 5S score was tracked every week, right next to labor efficiency and on-time delivery. When it slipped, we felt it in defects and missed deadlines before anyone could name the problem. Later, bringing those lessons to Emerson's InterMetro division, I kept arriving at the same conclusion: this discipline works anywhere people do complex work - including the digital world most of us live in today.
The Five S's
First S
Sort - Remove what doesn't belong
When I joined Jabil, tooling costs were high but operators constantly complained the right tool was never available. Turned out, first-shift workers were hiding torque screwdrivers and precision bits in their personal lockers - afraid the tools would disappear overnight. Nobody was accountable. So the tools drifted.
I audited every assembly area, collected everything, tossed what was broken, and labeled each tool back to its specific workstation. The missing-tools problem went away almost immediately.
Digitally: Uninstall apps you haven't opened in 60 days. Delete the duplicates. Close the tabs you've been meaning to read "someday." When things have no clear home, they drift - just like those screwdrivers.
Second S
Set in Order - A place for everything
At Jabil, one product was a disk enclosure that took 18 to 24 hours of labor to build - 5 levels of assembly, 140 components. I watched the operators and noticed something obvious once you saw it: most of that time was not building. It was searching for parts.
I reorganized the area into a U-shaped workcell with labeled shelves and a location map for every component. Pick time dropped 30%. Floor space shrank 60%. The assembly did not change. Finding the right part stopped being a decision.
Digitally: One folder structure. One notes system. Bookmarks organized by workflow. Your system should know where things live so your brain does not have to.
Third S
Shine - Clean up regularly
At Jabil we did a joint floor walkthrough every week - operations manager, production manager, industrial engineer, manufacturing engineer, EHS engineer - all walking together. The cleaning was almost incidental. What we were really doing was inspecting. Those walks surfaced lapsed calibrations, quietly growing backlogs, process steps that had drifted from standard. Without the cadence, problems grew in the dark until they were expensive.
Digitally: A weekly inbox sweep. A monthly downloads pass. A quarterly app audit. The value is not tidiness - it is the inspection that comes with it.
Fourth S
Standardize - Make it systematic
The most impactful thing I ever standardized at Jabil was a piece of paper. Mainframe assembly had hundreds of parts across multiple sub-assembly levels. The top defect: a missing screw. Cheap to prevent, very expensive when a customer found it. We introduced a screw counting template - kit and count every screw before you start, and if any are left over at the end, stop and verify. Twenty minutes of structured setup eliminated an entire defect class that had been triggering field repairs and returns.
Digitally: File naming templates. Email filter rules. A weekly review ritual you actually follow. Every micro-decision you eliminate is a small piece of mental energy back in your pocket.
Fifth S
Sustain - Make it a habit
At Jabil, 5S was a KPI - tracked, scored, reviewed weekly. I became the first person at the Poughkeepsie site to earn Lean Six Sigma Bronze certification, which required five documented improvement projects validated at three levels: plant, regional, and corporate. Then I drove five more colleagues through the same process. The certification was not the goal. Building a team where maintaining the system was part of the job - that was the goal.
Digitally: Block 15 minutes on Friday for a quick scan. Use tools that enforce structure rather than just offering it. Entropy is the default state. Without deliberate maintenance, your workspace drifts back to chaos every time.
Why It Works
Remember round one of the game? Every number was a hunt. That hunt is what your brain does dozens of times a day - searching for a file, remembering where you saved something, deciding which app to open. Each one is small. Together they are a constant tax on your focus. 5S removes the hunt. And when the hunt is gone, the work gets easier without you working any harder.
