Lean Six Sigma Training

The elements in lean six sigma training

Lean Six SigmaThe principles of “lean manufacturing” are mostly used by the engineers, managers, supervisors, and individuals responsible for the implementation of lean six sigma methodologies with in an organization.

Lean six sigma is a methodology of business improvement, which is the combination of lean manufacturing and six sigma tools. The aim of lean six sigma is the production of products which yields the “better quality faster”.

An organization implement the use of lean six sigma in order to reduce the time of production with the high quality expected. This is possible through the combination of the lean manufacturing and the traditional six sigma methodology. While lean manufacturing pays attention towards the speed, the traditional six sigma focuses on the quality of the product. Both action results in the production of a “better quality faster”.

The implementation of lean six sigma acts as an inter process inspections, in order to find out and eliminate the defective units. Lean six sigma gives importance in finding out the cause of defective units rather than further processing. Here lean manufacturing is the systematical approach of identification and the elimination of waste through continuous improvement by the flow of products, which meets the demand of the customer.

The philosophy of lean manufacturing is derived from the “Toyota Production System”. Lean manufacturing is a generic process of management, for the production of goods through the removal of waste and implementing the flow. The operational strategy in lean manufacturing gives importance in the achievement of better production of goods that meet the customer’s satisfaction, through the process of shortest possible cycle time by eliminating waste and reducing incidental work. Lean manufacturing is a technique which helps in decreasing the time between the customer need and the shipment. It is designed in a way that there is a rapid improvement in the profit, gaining the customer satisfaction, reducing the production of time and sustaining the employee emotions. In general it is said that lean manufacturing is considered as a company’s “half human effort, the half manufacturing space, the half investment in tools and the half engineering hours for the development of a new product with in the half time scheduled”. It is clear that the benefits gained through the implementation of lean manufacturing is the lower costs, higher quality and shorter lead time for the production.

The participants are given training about the importance of lean six sigma manufacturing. Along with this they are trained how and when to implement the methodology of lean manufacturing with in an organization, for the profit and to meet the customer satisfaction. The training starts with the characteristics of lean processes and the approaches.

The characteristics of lean processes are:

-Single-piece production

-Repetitive order characteristics

-Just-in-time materials or pull scheduling

-Short cycle times

-Quick changeover

-Continuous flow work cells

-Collocated machines, equipment, tools and people

-Compressed space

Lean manufacturing approaches:

Lean Six Sigma-2Lean manufacturing is used under two approaches. The first approach is used for the identification and the continuous elimination of the waste. It is clear that as the waste is being eliminated, the quality of the product improves, while the production time and cost is reduced. The second approach to lean manufacturing, is focusing on improving the “flow” of the work. By the word flow means, the smoothness of the work. in the second approach the focus is given in the smoothening of the work, through the system and not the waste reduction. The second approach was promoted by Toyota.

The difference between the two approaches lies not on the attainment of the goal, but achieving the goal at the first time itself. In the second approach, the smooth flow of the work helps in exposing the defects or the quality problems which is there in the work already. This exposing of the defects leads to  the reduction of the waste naturally.

once the lean processes and the approaches are cleared it is essential to make the participants know about the types of waste. this is because the aim of lean manufacturing is the elimination of wastes for the production of good quality products with reducing the time and costs.

Types of wastes:

The elimination of waste is the goal of lean manufacturing and Toyota defined that there are three types of waste like: “muda, muri and mura”.

MUDA: muda is process of activity that results wasteful or which does not add any value to the production of goods which meets the customer satisfaction. There are seven types of muda. They are as follows:

Overproduction: production of goods beyond the demand

Transportation: moving the products that is not required for the processing

Waiting: wasting the time waiting for the next production step

Inventory: all the necessary steps like components, work-in-progress and finished products not being processed

Motion: movement of the people or the equipments more than it is needed for the processing

Over Processing: the result of poor tool or product design creating activity

Defects: the efforts used in inspecting and fixing the defects.

MURI: The pushing of a person or a machine beyond its natural limits with in a work is referred as muri, which is another type of waste. All types of unreasonable works that the management is imposing towards the workers and the machines comes under this category. This is because of the poor management organization. Poor management organization such as making carry heavy weights, moving things around, dangerous tasks, even working faster than usual

MURA: This is the action which focus on the implementation and elimination of fluctuation at the scheduling or the operational levels. This includes the levels of quality and volume.

The above said are the basis of lean trainings. The training centre also pays attention to the topics like:
