Business Solution · Change & dependency impact analysis

Know what a change touches before you make it.

Declare relationships such as serves, calls, reads, writes, and depends_on in plain text. Scapius validates them and compiles views of upstream callers and downstream systems for any part of the landscape.

Why this is hard today

Modifying or retiring a system frequently causes unexpected downstream breakage because integration dependencies and shared data flows are documented across disparate, outdated diagrams.

Why integration landscapes bring clarity

Directional relationships

See declared callers, data consumers, and dependencies checked by the compiler.

Boundary definition

Isolate critical transactional workflows from peripheral integrations and external APIs.

Change impact

Evaluate upstream callers and downstream dependencies before deploying code or changing APIs.

Decisions enabled

Decisions informed by this model

Direct model queries replace subjective opinions with objective architecture evidence for leadership discussions.

Blast radius visibility

Identifies declared upstream callers and downstream systems within a proposed change boundary.

Dependency review

Surfaces integration contracts and data flows for review before changes ship.

Consistent review boards

Supports architectural review boards with query-driven, consistent landscape views.

Key review question

“Which applications and delivery teams will be impacted by the proposed change boundary?”

How your architects maintain it

Defined as clear, structured text

Architecture specialists declare directional relationship verbs (serves, calls, reads, writes, depends_on) in plain text. Scapius validates relationship rules and compiles focused landscape and container views on demand.
