The manager of the firewall team is getting complaints from various IT teams that firewall changes are causing issues. Which of the following should the manager recommend to BEST address these issues?

A scheduled review meeting gives all relevant IT stakeholders visibility into planned firewall changes before they are pushed, enabling teams to identify potential conflicts or service impacts in advance. This mirrors the ITIL Change Advisory Board (CAB) process, which is specifically designed to evaluate changes across organizational boundaries and prevent unintended consequences. Involving affected teams upstream transforms a reactive complaint process into a collaborative, preventive control.

Updating the change request form improves documentation quality but does not create a collaborative review process where affected teams can surface cross-functional impacts before the change is applied.

A secondary firewall administrator review adds a technical peer-check layer but does not include other IT teams whose services may be disrupted, so it fails to address the cross-team communication gap.

Verifying the change with only the requesting team after it has already been pushed is a reactive measure that does not prevent disruption to other teams who were never consulted during the planning phase.
