2. SOA maturity of your organization

Meaning of the different levels

...

Level 1 Ad-hoc

...

is the starting point for most SOA journeys. At this level, SOA is likely to be a relatively new concept for your organization. You may have taken few real steps toward SOA or have conducted some limited, initial web services or service-based activities that are project-centric, experimental and often technology focused.

...

Level 2 - Basic

...

Typically, enterprises at Level 2 have made a firm commitment to adopting SOA, although this may still be limited to certain parts of the organization. Organizations at this level have completed a pilot or initial project with SOA applied consistently across the project and will have deployed a set of services that are in production use by their business.

...

Level 3 - Standardized

...

Enterprises that have achieved Level 3 maturity have adopted SOA as a strategic enterprise-wide architectural principle. They have also established an enterprise service catalog, and an enterprise-wide service model is defined and used. In addition they have a defined set of SOA standards and are applying it across the enterprise. Governance systems ensure that all new projects are compliant with the enterprise’s SOA principles.

...

Level 4 - Managed

...

At Level 4, SOA is fundamental to the way the enterprise operates both its business and its information technology, and services may extend outside the enterprise. The enterprise’s service portfolio is well-managed with quantitative, integrated, enterprise-wide visibility and control of service operations. Service operational metrics are collected and reported in both business and technology contexts, according to the audience.

...

Level 5 - Adaptive

...

When an enterprise reaches Level 5, it can accurately be described as an Adaptive Enterprise. The whole enterprise operates a dynamic SOA with business and IT synchronized to achieve an optimum balance of agility, performance, risk and cost.

The domains

...

The Business Domain

SOA adoption has an impact upon and provides benefits for both business and IT. In order to successfully adopt SOA across the enterprise, it’s imperative that both business and IT commit to the program. Both sides must recognize that there will be different ways of working, and both should recognize that there will be benefits realized for each.

...

In the Operations and Management Domain, processes and policies defined in the governance model are applied. The domain covers all aspects of operating and managing our service-oriented architecture. In addition to stronger governance, the more flexible and dynamic SOA environment demands significantly stronger management. Management refers not only to managing technology, but to managing the technology in terms of services delivered by the technology, both IT services and business services. When a particular piece of hardware technology fails, or when a particular device is no longer available, we need to understand which services required that device to be there in the first place.

...

The Enabling Technology Domain

...

Of all the SOA domains, the Enabling Technology Domain has received the greatest attention and is probably the best described and understood. The Enabling Technology Domain encompasses the tools and technologies needed to support achievement of the goals of the other seven SOA domains and to realize the infrastructure needed to support a serviceoriented architecture within an enterprise. The focus is upon the software and hardware technologies that are specifically required for the implementation of a service-oriented architecture.
