Six Sigma Success Factors

Six sigma is a process of gradual improvement and continuous based on the survey that focused on customer demand which is the highest quality standards in manufacturing business. Customer request form is then implemented in product design and production in the production area. If in the production of goods do not meet the standards expected of consumers it must be in the review, in the redesign and production again to produce a product that really fit with customer demand.

Six sigma for improvement cycle is deceptively simple, but in practice will make busy the entire plant. Starting from the cleaning service, machine operators to top management. All should earnestly perform the appropriate production orders with the main objective, which is presenting the best quality according to customer needs.

Storage space and Product Variations

To reduce the level of preparation of a warehouse, warehouse space size should be minimized. Nevertheless, the situation with Kanban JIT production system is currently considered the need for a number of stocks in the warehouses of spare parts made by the previous process. The reason is:

1. When the system is taking a fixed amount and the cycle does not remain in use, the former should have a number of stocks of spare parts so to adjust to the scheduling decision is not necessarily time. With this system, the scheduling of the retrieval time is not necessarily due to fluctuations in demand in foreign markets.

2. When the system is fixed and the numbers of retrieval cycles used are not fixed, the former should have some preparation to adjust to the number of shots that are not fixed by the next process. Again, with this system, the number of shots because of the behavior of white fluctuating customer demand.

The importance of Information Monthly and Daily Information

Toyota is a member of two types of information on suppliers: First is a monthly production plan which has been determined previously notified to suppliers in the middle of the month before. By using the monthly production plan has been determined in advance, the supplier will determine the date of the following plans:

1. Cycle time of each process
2. Routine operation reorder raw labor allocation in accordance with a cycle time in each process.
3. The number of spare parts and materials to be ordered on the sub suppliers
4. The number of kanban for each sub-suppliers

Supplier Kanban and sequence schedule used by the supplier

Sometimes a very powerful businessmen may order its suppliers to deliver parts on time (JIT). In this case, if the plant on the retailer to implement Kanban system without changing its own production system. Kanban system will be something that is heavy for its suppliers. Although the kanban system is a very effective way to realize the concept of JIT. This system should not be applied to the supplier without any change in the overall production system user company. Kanban system is only a subsystem of the Toyota production system requires a total reorganization of the existing production system.

The Quality Control Circle Tools

The method presented the results of improvement should be carried out effectively and systematically. Submission must be understood by everyone and comprehensive. Results are accurate and systematically obtained from the appropriate data collection, appropriate methods, use of assistive devices, use of software for data analysis as appropriate.

Several tools and methods of presenting the results of improvement for the QCC Tools;
1. Process flow chart
2. Check sheet
3. brainstorming
4. Pareto diagram
5. histogram
6. Run Chart
7. decision Matrix
8. Cause and effect diagram
9. radar Chart

Grasp the Present Situation

Mastery of the situation will be very important research project. For that a project must involve people who are In-Charge and working in the relevant section. Person In charge who really understand the process flow, and the problem of raw materials, machinery and the type of damage that often occurs and the process of repair, defective products produced along with the frequent and so forth. Therefore, when there are problems can be directly aware of the problem point and picture completion.

Six sigma team must really have a solid skill for each job that needed improvement in research. The first one should be someone who really mastered the situation particularly on the process / section that will be the project. And the best person is the PIC (Person In-charge).
