Statement of the Problem

It was agreed that data in safety related systems is not currently sufficiently addressed in current safety management practices and standards. It is acknowledged that data has been a contributing factor in several incidents to date. There are clear business and societal benefits, in terms of reduced harm, reduced commercial liabilities and improved business efficiencies, in investigating and addressing outstanding challenges related to safety of data.

Agreed Vision

To have clear guidance on how data (as distinct from the software and hardware) should be managed in a safety related context, which will reflect emerging best practice.
