It’s surprising to see that many organizations or people perceive 5S as a housekeeping exercise and therefore don’t use it.
The fact is that 5S is an ideal starting point of Kaizen/ Lean journey as it helps to build the foundation. It tests the level of discipline of the management & its employees. It helps to achieving & maintaining a clean and orderly workplace. It helps the Gemba (real place) to speak for itself. It's easier to locate tools and equipment in an organized and standardized work area. A cleaned and straightened work area also gives a better impression when customers visit. Developing self-discipline ensures that a clean and well-organized work area stays clean and well-organized.
5S is a tool for systematic approach for productivity, quality and safety improvement.
Working in an unorganized or untidy environment is neither productive, nor safe. 5S is a simple tool that helps to make the work area clean & organized. It helps to instill a quality culture. It is relatively easy and requires minimal additional resources. The time & efforts invested in 5S gets paid off in a much bigger way when the results are realized. Below given are the few benefits of implementing 5S:
1. The work place become clean, safe, well organized & more pleasant
2. Space utilization is improved or space is released
3. Since non-value added activities are minimized the workflow becomes smoother
4. Time for searching tools, material & documents is minimized
5. Equipment life is extended as machine breakdowns are reduced
6. Defect free products/ services can be delivered as errors are minimized
7. Productivity & quality of the products and services improves
8. And last but not the least the employee morale & satisfaction improves
What is managements role in 5S?
Like in any other activity, managements role in 5S is equally important. Management has to facilitate & support the 5S initiative by:
1. Allowing employees time for 5S implementation
2. Providing resources
3. Showing personal interest by getting involved in it
4. Creating financial & non-financial reward system
5. Promoting 5S at all levels and by engaging everyone
Guidelines for implementing 5S
For effective implementation of 5S, it would be important to:
• Sensitize everyone (from doorman to chairman) about the importance and benefits of 5S and get their commitment;
• Conduct a status audit with photographs ‘as is state’.
• Measure throughput time, time in materials handling, floor space, annual physical inventory time, etc. by using before and after the 5S implementation.
• Develop an implementation plan, with clear roles & responsibilities and deadlines, in consultation with management and all employees concerned;
• Implement the 5 S plan;
• Take photographs after the implementation and see the difference;
• Share the experience and extend the implementation to other areas;
• Conduct periodic 5S Internal Audits with ratings to monitor progress.
So to conclude 5S system is not a housekeeping program, it is a problem prevention & problem identification system, so when something is out of place, the process should be to repeatedly ask why until we find the root cause and take corrective action. Taiichi Ohno said that until you have asked why five times, you probably have not found the root cause. Thus, the 5 Why root cause process is to ask, “Why, why, why, why, why” until you have found the source, or root, of the problem. Sometimes five times of asking why is not enough, and you have to ask it several more times.
A good 5S program produces good housekeeping, but it is just an outcome, not the goal. Five S should be a problem prevention tool and a way to identify & fix problems when they are still very small, and thus preventing big problems.
