The 5S methodology is a way to reorganize your office and practice to make it more efficient.

The 5S are Sort, Set in Order, Shine, Standardize, Sustain.

  • Sort: Remove the unnecessary item;
  • Set in Order: Put in order what remains focusing on efficiency;
  • Shine: Clean and inspect the work area to keep it in order;
  • Standardize: Standardize the work practice, in this way everyone knows how to work keeping in mind the above 3s;
  • Sustain: Continuously use the 5s;
Example: The first step is sort, so for instance, in IT, you need to remove code that you don't use or comment on. The set in order phase is about putting the remaining code in the proper order, and an example can be refactoring code. In the shine phase, you have to clean up your code, maybe use the appropriate formatting, adjust the comment, and so on. In the standardize phase, you can make a central object or library to use or define the standard for the future line of code. Finally, in the sustain phase, you need to use the 5s continually.

For the exam you need to remember:

  • The target of the 5s is about reorganizing your office and practicing to make it more efficient;
  • The 5s are Sort, Set in Order, Shine, Standardize, and Sustain;
  • It’s essential to use the 5s continuously, it’s not a single shot work.
