The Bottom Line

Processes exercise Services. The planned Processes Inventory will govern Process records; the Services Inventory connects to it through Related Processes. A Process may exercise one or more Services as part of its sequencing; a Service may be exercised by one or more Processes. This relationship enables joint Process and Service Management analysis: when a Process is redesigned, which Services are affected; when a Service is changed, which Processes are affected.

Core Concepts

ConceptDefinition & Strategic Role
ProcessA sequenced activity that orchestrates work to produce a business outcome — governed in the planned Processes Inventory.
Exercise RelationshipA Process exercises a Service when the Process invokes the Service as part of its sequence — different from the Value Stream participation relationship which operates at a higher level.
Joint AnalysisProcess redesign requires Service impact visibility; Service changes require Process impact visibility; the joint relationship surfaces both directions.

Quick Q&A

Question: How does the Service-Process relationship differ from the Service-Value Stream relationship?

Answer: Both involve a Service being invoked, but at different granularities. The Value Stream is the stable end-to-end flow of value to a stakeholder — the customer journey, the employee onboarding journey. The Process is the operational mechanism that handles a portion of that journey — the specific sequence of steps the work follows. A Service participates in a Value Stream (broad, durable) and may be exercised by multiple Processes within that Value Stream (specific, operational).

Question: Why does the Services Inventory care about which Processes exercise it?

Answer: Because Service changes affect the Processes that depend on them. When a Service Owner changes a Service’s inputs, outputs, expectations, or fulfillment model, every Process exercising that Service may need to be updated to remain consistent. Without the Service-Process relationship, Service changes can quietly break downstream Processes; with it, the impact is visible before the change is made.

Processes exercise Services. The Processes Inventory is planned as part of the IF4IT Noun Type taxonomy — refer to the IF4IT Enterprise Inventory Management Best Practices document for its current definition. The Services Inventory anticipates this relationship through the Related Processes attribute in the Relationship Attributes category.

The relationship is distinct from the Value Stream relationship. A Value Stream is the stable flow of value; a Process is the sequenced activity that operationalizes part of the Value Stream. A Process may exercise one or more Services as part of its sequencing, and a Service may be exercised by one or more Processes. This relationship enables joint Process and Service Management analysis: when a Process is redesigned, which Services are affected; when a Service is changed, which Processes are affected; where Process automation could substitute for human-delivered Services.
