Development Interface Agreement

Development Interface Agreement is a document that defines interfaces and documents between customer and supplier.It is required for safey related systems according to ISO 26262:

1. the appointment of the customer’s and the supplier’s safety managers,
2. the joint tailoring of the safety lifecycle in accordance with ISO 26262-2:2011, 6.4.5,

   NOTE 3 In the case of a distributed development, the relevant parts of the work products necessary for the activities of the development parties involved can be identified and exchanged.
5. the parties or persons responsible for the activities,
6. the communication of the target values, derived from the system level targets, to each relevant party in order for them to meet the target values for single-point faults metric and latent faults metric in accordance with the evaluation of the hardware architectural metrics and the evaluation of safety goal violations due to random hardware failures (see ISO 26262-5), and
7. the supporting processes and tools, including interfaces, to assure compatibility between customer and supplier.
