Six Sigma is the effective application of a set of system tools integrated by the logical path to solve problems, achieving the goal of breakthrough improvement. The tools in each stage ensure the rigor and logic of the Six Sigma in the problem-solving era.

You can only see the landscape within a few kilometers with the naked eye, but you can see farther with a telescope; With a microscope, you can see more carefully. It is through the combined application of these I-integrated tools that Six Sigma has shown outstanding effects in grasping the status quo, identifying the causes, breaking through the improvement and effective control.

Two, six kinds of horse management tools in Carnot analysis:

KANO model of customer demand was put forward by Dr. NORITAKI KANO of Japan. Carnot model defines three types of customer needs: basic, expected and attractive. According to the performance indicators, these three needs are divided into basic factors, performance factors and incentive factors.

1 Basic quality (demand)

Also known as quality, of course. If this demand is not met or the performance is not good, the customer's dissatisfaction will increase sharply, and after this demand is met, the customer's dissatisfaction can be eliminated, but it will not bring about an increase in customer satisfaction. The basic needs of products often fall into this category. For this demand, the enterprise's approach should be to be careful not to lose points in this respect.

2 Expected quality (demand)

Also called unitary quality. If this demand is met or executed well, customer satisfaction will increase significantly, and if this demand is not met or executed badly, customer dissatisfaction will also increase significantly. This is a demand in the growth period, which is the concern of customers, competitors and enterprises themselves, and also the embodiment of competitiveness. For this demand, enterprises should pay attention to improving the quality in this respect and strive to surpass their competitors.

3 Charm quality (demand)

Once this demand is met, even if the performance is not perfect, it can lead to a sharp rise in customer satisfaction, and if this demand is not met, it will often not bring customer dissatisfaction. This kind of demand often represents the potential demand of customers, and the approach of enterprises is to find and explore this kind of demand and stay ahead of competitors.

Basic requirements are the requirements or functions that customers think the product should have, and these basic requirements are the functions that the product should have. If the product can't meet these basic needs, customers will be very dissatisfied. On the contrary, when the product fully meets the basic needs, customers will not be particularly satisfied because they think this is the basic function of the product.

In market research, customers usually talk about expected demand, and the more expected demand is realized in products, the more satisfied customers will be.

Charming demand is an unexpected product feature that guides customers. If the product does not provide such requirements, customers will not be dissatisfied, because they usually do not think of these requirements. But when the product provides such demand, the customer is very satisfied with the product.
