Kaizen values so much the process as the result. In order that the people become jumbled in the continuation of their effort they kaizen the management must glide, organize and execute with well-taken care of the project. Often, the managers wish to see the result too much and ignore a vital process. The 5S “are not a fashion” nor the “program” of the month, but a conduct of the daily life. Therefore, all project kaizen needs to include pursuit passages.
Since they have been kaizen for against the resistance of the people to the change, the first step consists of mentally preparing the 5 employees so that they accept S before beginning to the campaign. Like a preliminary aspect to the effort of the 5S, must assign a time to analyze the implicit philosophy of the 5 S and its benefits:
  • Creating ambient of it worked clean, hygienic, pleasant and safe.
  • Revitalizing to gemba and improving substantially the mood, the moral and the motivation of the employees.
  • Eliminating the diverse classes of dumb diminishing, the necessity to physically look for tools, doing easier the work of the operators, reducing the exhausting work and releasing space.
The management also must include/understand the many the 5 benefits that S in gemba for the totality of the company; between these we mentioned:
Seiso, in particular, increases the trustworthiness of the machines, leaving of this one form more free time to the maintenance engineers to work in machines that are prone to sudden failures. Like result, the engineers can concentrate themselves in primary aspects that greater importance, like the preventive maintenance, the predictive maintenance and the creation of equipment frees of maintenance, in collaboration with the design departments.

The five passages of housekeeping, with their Japanese names, are the following:
  1. Seiri: to differentiate between elements necessary and unnecessary in genba and to unload these last ones.
  2. Seiton: to arrange in form ordinate all the elements after seiri.
  3. Seiso: to maintain cleanings the machines and the atmospheres of work.
  4. Seiketsu: to extend towards the one same concept of cleaning and to practice the three previous steps continuously.
  5. Shitsuke: to construct self-discipline and to form the habit to commit itself in the 5S by means of the establishment of standards.
In the introduction of housekeeping, frequently the western companies prefer to use equivalents in English of the 5 S Japanese, like in a “Campaign of the 5 S” or one “Campaign of the 5 Cs”.

The first passage of housekeeping, seiri, includes the classification of the items of Genba in two categories - necessary and the unnecessary thing and to eliminate or to eradicate of Genba this last one. A top must settle down on the number of necessary items. In Genba all class of objects can be. A meticulous glance reveals that in the daily work it is only needed I number small of these; many other objects would never be used or only they will be needed in the future distant. Genba is full of defective machines without use, sieves, dies and tools, products, work in process, raw materials, provisions and parts, shelves, containers, writing-desks, banks of work, document archives, carts, shelves, platforms and other items. A practical and easy method consists of retiring any thing that is not going away to use in next the 30 days.

Frequently, seiri begins with a campaign of red labels. It selects an area of Genba like the place for seiri. The 5 members of designated S go Genba with handfuls of red labels they place and them on the elements that consider like unnecessary. At the most great they are the labels and greater it is its number, better. When it is not clear if a certain item is needed or not, a red label must be placed on this. At the end of the campaign, it is possible that the area is covered with hundreds of red labels, which takes to compare it with woods of maples in autumn.

Once seiri has been carried out, all the unnecessary items have retired of Genba, only leaving necessary the number minimum. But these items that are needed, such as tools, can be elements that do not have use if they store too much far from the workstation or place where they cannot be. Take us stage to the following of the 5S, Seiton.
rmalidad and to undertake therefore the corresponding remedial action.

Seiso means to clean the work surroundings, including the machines and tools, just like floors, walls and other areas of the work place. Also there is an axiom that says: Seiso means to verify. An operator who cleans a machine can discover many defect of operation. When the machine is covered of oil, soot and dust, is difficult to identify any problem that can be forming. Nevertheless, while one cleans the loose machine we can detect with facility an oil flight, a crack that is forming in the cover, or nuts and screws. Once recognized these problems, because in being solved with facility.

One says that most of the failures in the machines begin with vibrations (due to loose nuts and screws), with the strange particle introduction as dust (as a result of cracks in the ceiling, for example), or with a lubrication or it lubricates inadequate. Therefore, seiso constitutes a great experience of learning for the operators, since they can make many discoveries useful while they clean the machines.

Seiketsu means to maintain the cleaning of the person by means of use of suitable clothes of work, lenses, gloves and shoes of security, as well as to maintain surroundings of healthful and clean work. Another interpretation of seiketsu is to continue working in seiri, seiton and seiso in continuous form and every day.

For example, it is easy to execute the process of seiri once and to realise some improvements, but without a effort to continue such activities, in a moment the situation will return to which was originally. It is easy to do only once kaizen in Genba. But to realise they kaizen continuously, day after day, is a completely different subject. The management must design systems and procedures that assure the continuity seiri, seiton and seiso. The commitment, endorsement and involvement of the management in the 5S become something essential. For example, the managers must determine whereupon frequency is due to carry out seiri, seiton and seiso, and what people must be involved. This must be part of the annual program of planning.

Shitsuke means self-discipline. The people who continuously practice seiri, seiton, seiso and seiketsu - people who have acquired the habit to do of these activities of their daily work acquire self-discipline.
