CEDAC

CEDAC is an acronym that stands for cause and effect diagram with the addition of cards. It is a very specific way of building a fishbone diagram in which team members contribute ideas written on 3 x 5 cards or Post-it notes.

CEDAC is a problem-solving tool that relies on brainstorming. The goal of CEDAC is to involve a large number of participants and to generate a high volume of ideas.

Using the cards also adds flexibility to the process of developing the cause-and-effect diagram. The ideas can be easily moved around as team members come up with more ideas. When posted on the wall using a large sheet of paper, CEDAC also lets numerous participants work on the fishbone diagram at the same time.
