Application Portfolio Management (APM) Best Practices

Overview

The Service Catalog describes what the organization offers to its customers and internal users in the language of services and outcomes. The application portfolio describes the technology assets that enable those services to be delivered. These two views of the organization’s technology capability are deeply complementary but are almost universally maintained without formal connection, producing a gap between the customer-facing description of enterprise capabilities and the underlying operational reality of how those capabilities are delivered and by which applications. This gap makes impact analysis unreliable - when an application is disrupted or retired, which services are affected and which customers are impacted cannot be determined without the connection that should have been maintained all along.

Best Practice

Establish and maintain formal relationships between every service in the Service Catalog and the applications in the portfolio that enable its delivery. For each service-to-application relationship, capture the application’s role in service delivery - is it the primary enabling system, a supporting tool, a data source, or an integration intermediary - and the criticality of the dependency. Review and update these relationships whenever a service’s delivery model changes, whenever an application undergoes a significant change or lifecycle transition, and as part of the annual portfolio governance review cycle. Use the service-to-application mapping as a mandatory input to application change and retirement decisions - no application that supports an active service should be changed or retired without a corresponding update to the Service Catalog and notification to service owners.

Benefit(s)

Connecting APM to the Service Catalog produces a unified view of service delivery that serves both service management and portfolio management purposes simultaneously from a single maintained connection. Service impact analysis becomes reliable when an application is disrupted or retired because the dependent services are explicitly mapped and their owners are known. Service design is informed by the actual application capabilities available to enable new services rather than by assumptions about what applications exist. The Service Catalog remains accurate as the portfolio evolves rather than becoming progressively disconnected from the operational reality of how services are delivered.
