Description The customer satisfaction model from N. Kano is a quality management and marketing technique that can be used for measuring client happiness. Kano's model of customer satisfaction distinguishes six categories of quality attributes , from which the first three actually influence customer satisfaction: Basic Factors . (Dissatisfiers. Must have.) - The minimum requirements which will cause dissatisfaction if they are not fulfilled, but do not cause customer satisfaction if they are fulfilled (or are exceeded). The customer regards these as prerequisites and takes these for granted. Basic factors establish a market entry 'threshold'. Excitement Factors . (Satisfiers. Attractive.) - The factors that increase customer satisfaction if delivered but do not cause dissatisfaction if they are not delivered. These factors surprise the customer and generate 'delight'. Using these fa...

What is Job Safety Analysis (JSA)? JSAs are used to describe how to perform a task step-by-step, any hazards associated with a task, and controls to mitigate these hazards. JSAs can be used to educate employees on safe practices prior to utilizing equipment. When should a JSA be created? JSAs should be developed for all equipment and specific operations that present safety hazards and/or concerns. Employees shall be trained on and have a good understanding of the instructions and hazards listed in the JSA prior to engaging in such work practices.

(From Wikipedia) In statistics, a histogram is a graphical representation of the distribution of data. It is an estimate of the probability distribution of a continuous variable and was first introduced by Karl Pearson. A histogram is a representation of tabulated frequencies, shown as adjacent rectangles, erected over discrete intervals (bins), with an area proportional to the frequency of the observations in the interval. The height of a rectangle is also equal to the frequency density of the interval, i.e., the frequency divided by the width of the interval. The total area of the histogram is equal to the number of data. A histogram may also be normalized displaying relative frequencies. It then shows the proportion of cases that fall into each of several categories, with the total area equaling 1. The categories are usually specified as consecutive, non-overlapping intervals of a variable. The categories (intervals) must be adjacent, and often are chosen to be of the same size. Th...

Một loại thuốc trà xanh có tác dụng "giảm cân". Có một loại trà đặc biệt được gọi là “trà xanh”, với rất nhiều những lời tán dương ca tụng về tác dụng của nó. Tuy vậy, không phải lúc nào trà xanh cũng tốt như ngươi ta nghĩ, và trong một vài trường hợp, nó có thể làm hại chúng ta. Trên thế giới có rất nhiều loại trà. Trà đen (các nước châu Á gọi là hồng trà) được sử dụng rộng rãi tại Châu Âu, Bắc Mĩ và Bắc Phi; chiếm tới 80% số lượng trà được sản xuất và tiêu thụ hàng ngày. Trà xanh chiếm phần lớn lượng trà còn lại, phổ biến nhất tại Trung Quốc, Hàn Quốc, Nhật Bản và Morocco. Chỉ có một lượng rất nhỏ trà trắng và trà Ô Long được sử dụng. Sự khác biệt lớn nhất giữa trà xanh và trà đen là chúng thường được sản xuất từ nhiều giống khác nhau của cây chè và cách chúng được xử lý.

Also called: Pareto diagram, Pareto analysis Variations: weighted Pareto chart, comparative Pareto charts A Pareto chart is a bar graph. The lengths of the bars represent frequency or cost (time or money), and are arranged with longest bars on the left and the shortest to the right. In this way the chart visually depicts which situations are more significant. When to Use a Pareto Chart When analyzing data about the frequency of problems or causes in a process. When there are many problems or causes and you want to focus on the most significant. When analyzing broad causes by looking at their specific components. When communicating with others about your data.
