When learning the 5S methodology, the vast majority of the time spent will be on the first four S’s. The last S, which stands for Shitsuke, or Sustain, however, is almost certainly going to be the most important one. Without this S, all the others would quickly fall out of use and the progress that a workplace makes would be lost. With this in mind, let’s take some time to go over what exactly ‘Sustain’ means and how it applies to a workplace.
What is Sustain
One the surface, the term sustain is quite simple. It basically just means to keep things the way they are and don’t let them fall backwards. When talking about 5S, this certainly does apply, but it actually goes significantly beyond this.
If you make a change in a process to eliminate waste, it is important to sustain that change. It is also important, however, to keep looking for further ways to improve the facility, and even that same process. So, in 5S, sustain actually doesn’t mean to keep things the same, but rather to keep them moving forward. A facility must have sustained improvement in order to be successful with 5S.
How to Sustain Improvement
Sustaining improvement requires not just a set type of action, but a change in the overall culture of a workplace. Rather than having employees who can follow set processes day in and day out, you want to encourage employees to look for opportunities for change that will benefit themselves, the company, or the customers.
This is essential because in the modern workplace, a company that is doing things the same way for months and years at a time is actually falling behind the competition that is continuously innovating. To help encourage sustained improvement, consider some of these ideas:
Idea Box – Having an ‘idea box’ or any other place where employees can submit suggestions on how something in the facility can be improved. This can be a physical box, an email account, or anything else that makes it easy for employees to recommend improvements.
Reward Improvements – When an employee comes up with an idea to make an improvement, they should be rewarded in some way if it is successful. Whether this is monetarily, with titles, or anything else.
Time – Giving employees time to develop ideas for improvement can really pay off in the long run. Allowing each employee up to 5% of their hours to spend on new ideas, for example, can encourage them to come up with improvement opportunities.
Of course, there are many other ways that a facility can help encourage people to look for improvement opportunities. The important part is to make sure that whatever the facility does to find improvement opportunities, it is continuously done without interruption.
Of course, a facility can’t be constantly making changes to every single area where work is being done. Part of sustaining progress is indeed making sure that successful changes are kept in place. This would include making sure that information is collected about the current state of the workplace so when an idea for improvement does come along, it will be much easier to measure its success against the known current status.
Sustaining is Essential
While sustain may be the last S in the 5S methodology, it is certainly not the least important. If you are currently implementing 5S, or you have been using it for years, make sure to take some time to really evaluate how your sustaining is going, and see if it can’t benefit from some improvement.
