The Enhanced SOA Process Framework

Improvements to the Solution Track

The solution track has been significantly enhanced with two new disciplines.

These changes allow the full spectrum of solutions, from one which actually employs no services at all to one founded upon existing services, to be covered.

Solution Architecture Design

To integrate business process architecture and system architecture as smoothly as possible.

To identify the service requirements to enable the solution.

Solution Provisioning

To plan sourcing and usage of a solution

To specify and design the solution

To ensure the solution (as an integrated whole) is fit for purpose; analogous to service provisioning.

Improvements to the Enable Track

We have enhanced the enable track to provide a more complete process framework, running right through to solution operation.

The remaining enable disciplines have been broadened to include solutions and well as services platform design and installation, and operations and management.

Solution/Service Platform Architecture

To design both the solution and the service infrastructure in terms of available processors.

Previously this activity was confined to services; we now broaden the approach to encompass solutions.

Solution/Service Deployment

To install both solutions and services in their target run time environments according to their specifications.

Previously this activity was confined to services; we now recognize deployment as significant in its own right and broaden the approach to encompass solutions.

Service-Oriented Architecture and Design Routes

Red Route: Existing Enterprise Service Portfolio Plan (SPP) Blue Route: No Existing SPP

The Need for Coordinated Architecture Scope

As Solution Architecture & Design progresses so requirements for services emerge.

These service requirements must be assessed with respect to the wider enterprise view.

Hence the need for Coordinated Architecture Scope

[Service Requirements, SPP Fragment]

Project charters produced by IT Strategy and Architecture that identify expected IT project costs and benefits, including projected Return on Investment from proposed services to be produced and reused by the projects.

The Service Oriented Business Plan output from SO Business Requirements Planning.

The Service Portfolio Plan (SPP) (for the enterprise or part of the enterprise), where this is available. Where an SPP is not available the service requirements must be evaluated with respect to the broader context and SOA policy evolved.

The Service Catalog and IT Inventory

Other outputs from IT Strategy and Architecture such as Enterprise Architecture models.
