Re: CEDAC (Cause and Effect with Addition Cards) - Sharing Experiences and Form(s)
Dear Members,
I have used this tool in my earlier co. wherein nine CEDAC projects worked on different problems. I can share the following details :
CEDAC
Background
• 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.
Typical Uses
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
• Inventory Reduction
• Reducing Rework / Scrap / Errors
• Increasing Yield
• Reducing Time and Cost Overruns in projects
• Cost Reduction
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:
1. Problem Definition
To define the problem precisely.
2. Improvement Measurement
Methodology for measurement
3. The Target Effect
Team defines the target as per set rules.
4. Fact Cards
Based on observation at workplace
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
10. Adherence
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 :
1. Total Elimination of two customer complaints through two projects.
2. Saving of Rs. 58 lacs through seven projects.
