Development Interface Agreement

L2 08 L Development Interface Agreement

What Goes into a DIA (Development Interface Agreement)?

A DIA (development interface agreement) defines the roles and responsibilities between companies involved in developing a product. All involved parties need to agree on the contents of the DIA before the project begins.

The DIA also specifies what evidence and work products each party will provide to prove that work was done according to the agreement.

The ultimate goal is to ensure that all parties are developing safe vehicles in compliance with ISO 26262.

Here are major sections of a DIA:

Appointment of customer and supplier safety managers
Joint tailoring of the safety lifecycle
Activities and processes to be performed by the customer; activities and processes to be performed by the supplier
Information and work products to be exchanged
Parties or persons responsible for each activity in design and production
Any supporting processes or tools to ensure compatibility between customer and supplier technologies
