By understanding the relationships between services and infrastructure components, IT teams can prepare for potential failures, minimize downtime, and ensure continuity of operations. This proactive approach reduces the impact of incidents and strengthens the overall resilience of the organization.

Enhancing Collaboration Across Teams

Discovery certification enables professionals to work effectively with multiple stakeholders, including IT operations, security, compliance, and business teams. Certified implementers provide accurate data that informs decision-making across the organization.
