Q-2. Why does 5S fail sometimes?

Answer: When a company chooses to implement a 5S system they will get started with the best procedure and intention but everything goes sideways after a time when people lose their focus on 5S and it falls apart. Before implementing the 5S companies should make sure they can take steps to avoid common problems. Let’s have a glance at why 5s fails to work sometimes.

 

•  Failing to get a proper buy-in from the top down will lead to failure over time. The 5S procedure requires proper commitment starting from front-line employees to the CEO or owner of the facility. A process that starts without commitment will lead to failure.
• Though the 5S is working well, not tracking the cost and benefits will lead to the failure of the companies. Without proper tracking of the expenses done by the company, even the 5S would not be able to help an organization.
• For the projects to be run successfully long-term 5S requires real direction to be followed. Having a core group of people who manage the 5S strategies will help to maintain the focus of the project. If the same is done abruptly once the mistake is discovered would also lead to a very disorganized and ineffective workplace.

Q-3. How can you simplify the sorting of things in a workflow?

Answer: In 5S sorting is the first step towards making the workplace better. There are three or four “bins” or sorting categories used when conducting a 5S sort.

Keep: Keeping the items used frequently and essentially accessible is crucial for the operation of the workplace. Sorting the things based on frequent usage is important.

Remove: Removing all the unnecessary items that are occupying the space is important, either it should be placed in a bin or piled to be removed

Probation: Items placed in the pile or bin should be evaluated to check for theirs. A time frame should be set to check for the appropriate usage of the items. In this probation period based on the usage of the items, they can either be discarded or organized back into the workspace.

To Move: Items that are not needed often but should be kept on hand for times when they are required will need to be relocated. These items will be put in new homes in other stations or rooms that require these items.

 Q-4. How can you start the 5S for an organization?

Answer: Starting to implement 5S is crucial for its success. It should start with employee buy-in. Employee buy-in means they should be open, willing, and committed to taking the risk of adapting to the changes in the system.

Some tips to develop an employee buy-in include:

• Making the employees learn about the 5S.
• Making a visual representation by providing examples and educating the employees on the success rate when it comes to 5S
• Providing insights about how the process works helps to remove some of the hindrances while running the process.

Throughout the employee buy-in process, many teams will work towards the success of the 5S by showing excitement and interest in discussions, while some would show the same towards the failure and hindrances that will happen with the new changes. However, once all the data are released, this would deliver great insight and information will be gathered on how to best approach the team in the future. 

Q-5. What is 5S housekeeping?

Answer: The 5S has proven to become a place of improvement for different kinds of workflow, it is called housekeeping as it needs to be done regularly. In fact,  among the 5S, the 5Th S Sustain is about looking back and making sure that the steps that were made in the previous S are maintained long into the future.

It is named housekeeping because without proper cleaning a house would become dirty and fall into despair. In the same way, a place that doesn’t follow any form of 5S will find that any progress that was made will be lost over time. This also includes the employee taking shortcuts for completing the work which would lead to a loss in workflow and efficiency of the product.
