TO CREATE AN INTERRELATIONSHIPDIAGRAM

• Agree on the issues or questions

• Add a symbol to the diagram for every element

involved in the issue.

• Compare each element to all others and use an

influence arrow to connect related elements.

• The arrows should be drawn from the element that

influences to the one influenced.

TO CREATE AN INTERRELATIONSHIPDIAGRAM

• If two elements influence each other, the arrow

should be drawn to reflect the stronger influence.

• Count the arrows.

• The elements with most outgoing arrows will be

root causes or drivers.

• The ones with the most incoming arrows will be

key outcomes or results.

AN EXAMPLE: LATE DELIVERIES

.

The inference is that potential causes for late delivery are:

• POOR SCHEDULING PRACTISES (6 OUTGOING

ARROWS)

• LATE ORDER FROM CUSTOMER (5 OUTGOING

ARROWS)

• EQUIPMENT BREAKDOWN ( 3 OUTGOING ARROWS)
