How should the ITIL Guiding Principle ' collaborate and promote visibility ' be applied?

The guiding principle “collaborate and promote visibility” should be applied by involving stakeholders and sharing information with them, so option A is correct. ITIL stresses that good decisions and effective work depend on people understanding what is happening, why it matters, and how they can contribute. Collaboration helps bring together different perspectives, knowledge, and responsibilities. Visibility ensures that work, progress, risks, and priorities are transparent enough for informed participation and trust. Limiting communication to management weakens collaboration. Reusing existing processes relates more to “start where you are.” Capturing feedback after each iteration relates more closely to “progress iteratively with feedback.” This principle helps organizations reduce silos, improve coordination, and create a more shared understanding of how value is being created across the service relationship.
