WHAT IS 5 S

 

5S (Five S) is a workplace organization method that uses a list of five Japanese words:  seiri ,  seiton,  seisō, seiketsu , and shitsuke. These have been translated  as "Sort", "Set In order", "Shine", "Standardize" and "Sustain". 5S describes how to organize a workspace to be efficient and effective by identifying and storing used items, maintaining space and objects, and maintaining new order. The decision-making process often arises from a standardized dialogue, allowing employees to understand how they should perform their work.

5S was developed in Japan and is identified as one of the techniques that enables just-in-time production.
Two main frameworks for understanding and applying 5S to the business environment have emerged, one proposed by Osada and the other by Hirano. Hirano provided a structure for improving programs with a series of definable steps, each building on its predecessor. As John Bicheno has noted, Toyota's adoption of the Hirano method is "4S", with Seiton and Seiso combined.

There are five 5S phases. They can be translated from the Japanese as "sort", "set in order", "shine", "standardize", and "sustain". Other translations are possible.

1.    Sort (Seiri). Seiri is sorting through all items in a location and removing all unnecessary items from the location.

·      Check all items in a location and evaluate whether or not their presence at the location is useful or necessary.

·      Remove unnecessary items as soon as possible. Place the things that cannot be removed immediately in a 'red tag area' so that they are easy to remove later on.

·      Keep the working floor clear of materials except for those that are in use to production.

2.    Set in order (Seiton) 2S – simple floor marking. Seiton is putting all necessary items in the optimal place for fulfilling their function in the workplace.

·      Arrange work stations in such a way that all tooling / equipment is in close proximity, in an easy to reach spot and in a logical order adapted to the work performed. Place components according to their uses, with the frequently used components being nearest to the workplace.

·      Arrange all necessary items so that they can be easily selected for use. Make it easy to find and pick up necessary items.

·      Assign fixed locations for items. Use clear labels, marks or hints so that items are easy to return to the correct location and so that it is easy to spot missing items.

3.    Shine/Sweep (Seiso) 3S – cleanliness point with cleaning tools and resources.

Seiso is sweeping or cleaning and inspecting the workplace, tools and machinery on a regular basis.

·      Clean the workplace and equipment on a daily basis, or at another appropriate (high frequency) cleaning interval.

·      Inspect the workplace and equipment while cleaning.

4.    Standardize (Seiketsu) 4S, Seiketsu is to standardize the processes used to sort, order and clean the workplace.

·      Develop a work structure that will support the new practices and make it part of the daily routine.

·      Ensure everyone knows their responsibilities of performing the sorting, organizing and cleaning.

·      Use photos and visual controls to help keep everything as it should be.

·      Review the status of 5S implementation regularly using audit checklists.

5.    Sustain/Self-discipline (Shitsuke) 5S. Shitsuke or sustain the developed processes by self-discipline of the workers. Also translates as "do without being told".

·      Organize training sessions.

·      Perform regular audits to ensure that all defined standards are being implemented and followed.

·      Implement improvements whenever possible. Worker inputs can be very valuable for identifying improvements.

·      When issues arise, identify their cause and implement the changes necessary to avoid their recurral.

How Spark Plugs Work

As engines and their electronics become more complex, one of the few things left to hobbyists and auto enthusiasts who like a little grease under their fingernails is the ability to change their spark plugs. Although just about every other car repair out there takes a code reader and a college degree to diagnose and fix, spark plugs remain accessible and easy to understand. The first reliable spark plug was invented in 1903 by Oliver Lodge. They're aptly named as well; spark plugs are simply insulated plugs that are screwed into an internal combustion engine's cylinder head to deliver the spark that ignites the mixture of air and fuel in the combustion chamber. Spark plugs also transfer heat away from the combustion chamber. Basically, this is what happens: The spark plug sits at the top of the cylinder head. The piston first travels down the cylinder, drawing in a mixture of fuel and air. The piston then goes back up toward the spark plug, compressing the mixture. At t...

THE RELATIONSHIP BETWEEN WORK PROCEDURES, WORK INSTRUCTIONS AND QUALITY CONTROL IN A COMPANY

  When carrying out a production process, you usually first determine the quality standard as seen from a work procedure outlined in the form of a work instruction which is created as a benchmark in determining the quality standard that will be used in making a product. Before knowing the relationship between the three theories and examples of cases that occur, first understand the meaning of these three theories. Are they? Let's look at the meaning below: 1. Procedure Procedures or procedures are a series of actions, actions or certain operations that must be carried out or carried out in a standardized (same) way in order to always obtain the same results from the same circumstances, such as Occupational Health and Safety Procedures, School Entry Procedures, Leave Procedures School, etc. More precisely, this word can denote a series of activities, tasks, steps, decisions, calculations and processes, carried out through a series of works that produce a desired goal, product or eff...
