The report’s findings, released on Monday, determined that the ASX met or exceeded industry standards in more than 75% of rated capacities, but also highlighted “shortcomings in rigor” in the management of risks, project delivery, testing and incident management.

ASX plays a crucial role in maintaining the stability of financial markets and therefore has a “near zero appetite” for downtime.

“Governance was transferred to a group that had a wide range of responsibilities, and the group did not include a key role. The change diluted the focus on the project, ”IBM found.

ASX chief executive Dominic Stevens said last week he had restructured the organization since the outage to strengthen accountability for important projects, changing key leadership roles and creating a direct line of command with the CEO.
