The ‘collaborate and promote visibility’ guiding principle in ITIL 4 emphasizes working with stakeholders to ensure transparency and alignment with their needs. TheITIL® 4 Practitioner: Release Managementdocument advises:"Applying the ‘collaborate and promote visibility’ principle involves working closely with stakeholders, such as service consumers, to understand their needs and ensure releases do not disrupt their operations, thereby ensuring an excellent user experience"(Section 5.1).

The issue is that updates interrupt work during peak hours, indicating a lack of collaboration with users to understand their schedules and needs.

Option A (Ensure an excellent user experience) directly addresses this by implying collaboration with users to schedule releases at non-disruptive times, aligning with the principle.

Option B (Review the effectiveness of release models) is an internal activity and doesn’t directly involve collaboration with stakeholders.

Option C (Optimize the practice for the value streams) focuses on value stream efficiency but doesn’t specifically address user collaboration.

Option D (Do not overcomplicate the practice) is unrelated to the collaboration principle.

The correct answer is A, as ensuring an excellent user experience through collaboration directly applies the principle to address the issue.
