The origin of the affinity diagram can be traced to a data analysis technique called the KJ Method, developed by Kawakita Jiro. The affinity diagram is largely a creative brainstorming process in which consensus is reached by visual (written) rather than verbal means. The affinity diagram can also be used as a management and planning tool that can help with the systematic analysis of large amounts of data. It is best used for translating large amounts of complex, apparently unrelated information, into natural and meaningful groupings of data.

Grouping related items helps to identify underlying relationships that tie ideas together. Clues about potential strategies for overall problem solving are revealed that can help discover new a structural pattern in performance improvement relationships.This tool organizes language data. Once brainstormed ideas are written on cards, they are grouped together with similar ideas (affinities) a header card is created which captures the meaning of each group of ideas. This is a creative, “right brain”, activity. In order to dilute the power of institutionalized ways of thinking about a perceived problem, the affinity diagramming process encourages a group to step outside their logical perceptions and apply their professional intuition. This process is also an effective method to use to generate a large number of ideas in a brief period of time.

It is a way to systematically map out in increasing detail the full range of paths and tasks that need to be accomplished to achieve a primary goal and each related sub goal. It is known as systematic diagram, tree analysis, analytical tree, or hierarchy diagram. It is used to divide different categories into specific and finer levels of detail. The tree diagram development helps us to move generalities to specifics thinking. The tree diagram starts with one item that divide into two or more parts, also each of which branch into two or more parts, and so on. It looks like a tree, with trunk and multiple branches

In this seminar report, we discuss about Seven Quality tools and Seven Management Tools, the basic seven come from Kaoru Ishikawa, which is known for “Democratizing Statistics”. The Basic Seven Tools made statistical analysis less complicated for the average person and good Visual Aids make statistical and quality control more comprehendible.

In our seminar report explain briefly the seven quality tools, using a systematic approach we also need to use tools which enable problems to be defined, data to be collected and analyzed, solutions generated and selected and the effectiveness reviewed. Help to identify and priorities problems quickly and more effectively. Simplify the decision making process. Provide simple but powerful tools for use in continuous improvement activity. Provide a vehicle for communicating problems and resolutions throughout the business.

In the second part of our seminar report we briefly describe about the seven management tools, the union of engineers and scientist in 1976 in Japan introduce the tools to communicate information, innovation promotion and to plan the major projects successfully.
