Process Navigator & Blast Radius Simulator

When a critical IT service experiences an outage or undergoes emergency maintenance, executive leadership requires an instant answer: “Which business processes, revenue streams, and customer journeys are disrupted?”

EasyEA’s Process Navigator & What-If Impact Simulator answers this question immediately by traversing the ArchiMate graph.

1. End-to-End Value Lineage

EasyEA interconnects all architecture layers along the business delivery flow:

graph LR
    BA[Business Actor / Customer] --> BP[Business Process]
    BP --> AS[Application Service]
    AS --> AC[Application Component]
    AC --> DB[Database & Middleware]
    DB --> ND[Technology Node / Cloud Cluster]

Within the Process Navigator, select any macro-process (e.g., Customer Onboarding, Payment Processing, Order Fulfillment) to drill down into:

Impacted Business Actors & Departments.
Supporting Software Components & Microservices.
Hosting Infrastructure Nodes, Kubernetes Clusters, or Cloud Services.

2. Interactive Blast Radius Simulator (What-If Analysis)

Test outage and change scenarios proactively before taking production actions:

Target Selection: Pick an application component, database cluster, or physical hypervisor.
Execute Simulation: Trigger the “Simulate Blast Radius” button.
Cascading Graph Traversal: EasyEA traverses upstream Serving, Realization, and Flow relationships, highlighting the disruption footprint:
- Critical Blocked Processes: Workflows that halt entirely without the target asset.
- Degraded Operations: Processes possessing fallback paths or secondary integrations.
- Affected Organizational Units: Teams facing operational disruption.
- Downtime Financial Impact: Projected hourly revenue disruption based on configured business metrics.

3. High-Value Scenarios

Change Management & Maintenance Windows: Prior to updating shared databases or API gateways, identify all dependent systems requiring testing.
Incident Response for SOC & NOC Teams: During security alerts or major outages, report the business impact footprint to executive crisis teams.
Risk-Free Decommissioning: Ensure that retiring legacy virtual machines will not inadvertently break unseen batch jobs.
