It creates clear, agreed-upon rules and schedules so everyone maintains the workplace the same way.
It encourages individual creativity in organizing space.
It is the step where you buy all new equipment.

Shitsuke challenge.
A student notices that after a long holiday, some classmates have started leaving anti-static wrist straps on the table instead of hanging them on the designated hooks. To practice Shitsuke, what should the student do?
Scold the classmates loudly.
Ignore it; it's not his/her problem.
Politely remind them of the standard and hang his/her own strap properly as an example.
Hide all the wrist straps.
You are assigned to lead the Seiri phase for the power cable bin. You find various cables (VGA, power cord, SATA, Ethernet). How would you CRITICALLY decide what to keep?
Keep all cables because they might be useful someday.
Test each cable for functionality. Keep only working cables that match current lab equipment.
Keep only the newest-looking cables.
Let the next group decide.
In your group's workstation, the Phillips screwdriver is constantly misplaced. Applying the principle of Seiton, what is the BEST long-term solution?

Agree; the janitor will clean it anyway.
Disagree; small trimmings are a safety hazard (can cause slips, short circuits) and show a lack of discipline, breaking the standard.
Disagree, but only because the teacher will get angry.

He/She has to ask the teacher every time.
He/She must search through all drawers.
You notice that the "LAN Tester" is often left on the workbench instead of being returned to its spot. APPLYING the 5S principles, what is the root cause you should analyze?
The students are lazy.
Perhaps its designated spot is inconvenient, or the label is unclear. (A Seiton/Set in Order problem).
The tester is too expensive.
There is no Seiso schedule for it.
While cleaning under a workbench (Seiso), you discover an unlabeled bottle of liquid. What is the SAFEST and most appropriate action based on 5S thinking?
Sniff it to identify it.
Pour it down the drain to dispose of it.
Show it to the teacher immediately for proper identification and disposal (related to Seiri/Sort for safety).
Place it on the shelf with other chemicals.
The class standard is to do a 10-minute mini-Seiso at the end of each period. Today's lab ran late, and your group has to leave quickly. What demonstrates true Shitsuke (Sustain)?
Taking at least 2 minutes to return tools and clear major debris, acknowledging the standard is important even when rushed.
Leaving everything as is because it wasn't your fault the lab ran late.
Promising to do double the cleaning next time.
Asking another group to clean your mess.
To improve the Seiketsu (Standardize) for tool return, you propose implementing a "check-out/check-in" logbook. How does this CREATE a system that supports Shitsuke?
It creates more work for the teacher.
It builds individual accountability and makes it clear who is responsible for which tool, encouraging discipline.
It allows students to take tools home.
It is only useful for expensive tools.
What is your expected grade this third grading period? Explain why?
