Governing Service Analysis Stages 191

Initial service delivery cost, effort, and timeis reduced because the analysis scope isbased on immediate project requirements.

Subsequent service governance requiresincreased cost, effort, and time because less strategic considerations were initially taken

into account.

The overall burden of subsequent servicegovernance is reduced because services were

modeled as part of an inventory.

Initial service delivery cost, effort, and time is increased because a blueprint of the inventory

is established prior to service delivery.

Figure 8.1 Generally, the less time and effort spent on the up-front service analysis, the greater the on-going, post-deployment governance burden. The approach on the left is comparable with bottom-up service delivery and the approach on the right is more akin to top-down delivery. SOA methodologies that attempt to combine elements of both approaches also exist.

Figure 8.2 A service inventory blueprint (bottom) is the primary deliverable of the Service Inventory Analysis stage. Depending on the project delivery methodology used, several iterations of this cycle may occur to produce this deliverable.

NOTE

The Define Enterprise Business Models step in the Service Inventory Analysis lifecycle refers to published business specifications, documents, and artifacts that provide suitable input for the Service-Oriented Analy-sis stage. Several of the precepts covered in Chapter 12 pertain to the definition of these types of business models as the basis of governance precepts.

SUMMARY OF KEY POINTS

The definition of the service inventory scope correspondingly determines the scope of the Service Inventory Analysis effort and further establishes a concrete boundary in which a collection of services will subsequently be delivered.

Business requirements prioritization helps determine the order and sequence of business processes and requirements that are processed through iterations of the Service Inventory Analysis cycle, which includes iterations of the Service-Oriented Analysis process.

SUMMARY OF KEY POINTS

The Service-Oriented Analysis stage is responsible for producing the very first incarnations of services and service capabilities, and therefore pres-ents an opportunity to establish precepts that can support eventual gover-nance tasks.

The primary governance responsibilities relate to the consistent definition and versioning of service candidates, and to ensuring their review before moving on to the Service-Oriented Design stage.
