The Architecture Framework lays the foundation for the enterprise and the Agile Project Management enables large organizations successfully manage and deploy SOA enterprise wide. Without adopting either - the traditional (structured) development methodology and process does not enable enterprises achieve the full benefit.

- Governance & Organization
- Standard Bodies
- Regulation & Compliance
- Management (of Programs, Projects, Services, Infrastructure, etc.)
- Security (could be considered as part of management - best broken out seperately)
- Business Process
- Development tools and Methodology
- Deployment tools and Methodology
Based on my discussion with BEA there are 4 Organization patterns/models (listed in the white paper available at http://eudownload.bea.com/uk/events/soa/soa.pdf). These models could be considered as:
Centralized, Hierarchial, Federated & Partially Federated and these models are typically structured the same way the Enterprise is organized. For example is the business is highly-centralized - then so is IT. This structure would typically not change for adopting SOA across the enterprise. Forrester has an excellent research paper on this - which you may want to download from their site.
It is easier to achive the reuse benefits of services in a centralized model. The issues for non-centralized (most large enterprises) organization is the structure/process required to get the benefits of reuse. The missing solutiuon for this is a centralized Service Repository with a Google like search capability. To make this a productive tool - every project manager & business would have to comit to document and publish their objectives, process, requirements, design, etc. (all the sharable assets) into this repository. Such a respository will have to leverage technologies such as Search (Goole Appliance, Autonomy, Verity, etc.) & Conetent Management Systems (Documentum, Interwoven, FileNet, etc.). Ofcouse - Microsoft provides similar capabilities but have not reviewed their products.
