Dear Members, CEDAC is a lean tool for Team oriented problem solving which uses groups creativity & collective wisdom for solving day to day problems.

I would like to attach the file CEDAC for information of all.



• CEDAC stands for Cause and Effect Diagram with the Addition of Cards;

• CEDAC is a visual, team-oriented problem solving methodology developed by Dr. Ryuji Fukuda.

• In 1978 he was honored with prestigious Deming Prize for this contribution to the field of productivity and quality improvement.

• CEDAC has been used extensively in Japan, USA and Europe with excellent results.

Dr. Fukuda’s message

• Management is a practical science.

• A Company must continuously improve its health in order to overcome competition.

• To achieve this, it is important for each person constituting the company to have a mechanism that enables him/her to always make progress on his/her own accord in daily work.

To summarize ………….

CEDAC is useful for organizational improvement for the following reasons:

• It orients all the members of the organization, directs their actions by graphically presenting the project, and allows them to effectively contribute to the improvement process.

• It allows sharing of necessary information with all members, thus promoting autonomous actions.

• It encourages all individuals in the organization to use their strengths.

• It increases chances to generate ideas that enable progress even by at least half a step, as it makes the members keep thinking.

• It integrates external knowledge and the member’s knowledge to create new ideas and technology.

• It standardizes ideas with favorable test results and accumulates them as intrinsic and management technology.
