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. Fukudas 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.
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 members knowledge to create new ideas and technology.
It standardizes ideas with favorable test results and accumulates them as intrinsic and management technology.
It is extensively used to encourage employee involvement in shop floor problem solving and to promote small group activities. Typical applications include
For Production & Services
Lead Time Reduction in production & services
Reducing Rework / Scrap / Errors
Reducing Time and Cost Overruns in projects
For Administration / Sales Offices
Reduce Late coming / Absenteeism
Speedy recovery of receivables
Increase Orders to Enquiries ratio
10 Step Process
CEDAC is a systematic 10 step process as follows:

4. Fact Cards

5. Analysis Cards
Breaking down the facts
6. Improvement Cards
7. The Three Dot Marking System
8. Implementation Plan
9. Standard Card
Which has been implemented to yield positive results
Through Control plans / Work Instructions, Poka yoke devices & FMEA
Each step requires a no. of tools & rules to be followed.
Typically in one organization where Nine CEDAC projects were run could get the following benefits :

2. Saving of Rs. 58 lacs through seven projects.
Some of the leading organizations that have benefited from CEDAC are
- Mitsubishi Heavy Ind.,
- Sumitomo Special Metals,
