Introduction

There are many definitions of SOA. Adoption scenarios for SOA also tend to vary considerably, especially when organizations lack a clear roadmap; the vision for how to proceed on their path to SOA adoption. The SOA journey does not start and end with a single project. As an increasing number of organizations continue to incorporate the use of service orientation as the foundation of their IT strategy, it will become increasingly important for them to assess their current state against several dimensions (from the business down to infrastructure) and identify ways to maximize business benefits from their SOA journey.

This article describes how the new Open Group Standard, Open Service Integration Maturity Model (OSIMM) and IBM's submission, SIMM, has been used by IBM to both assess services, SOA adoptions and to create blueprints for increasing business flexibility as well as IT flexibility. Additionally, SIMM is being used to help organizations achieve advanced levels of business agility and IT flexibility through service integration that are specifically in line with their unique SOA migration path and business objectives.

SOA and Service adoption paths require a gradual process which is often unique to each organization. Many organizations experiment with Web services (by wrapping existing applications) as a means of exploring the world of service integration and using it as a vehicle for deciding how to proceed from that initial state of maturity. Some organizations engage in an enterprise-wide business transformation. Other organizations define their roadmaps, vision, strategy, and criteria for assessment and governance. For any of those organizations, it’s useful to have an objective standard against which to measure current Service and SOA maturity and to create a roadmap to reach the desired level of maturity not for the sake of maturity alone, but to effect different business outcomes that can result from achievement of a specific level of maturity.

OSIMM provides architects, both Business Architects and IT Architects a prescriptive and practical means for going beyond the platitude of business flexibility and making this a measurable business and IT outcome.


What is the purpose of Maturity Models?

In general, maturity models represent a scale for assessing the current state of maturity and depicting the target state of maturity. Until now, with OSIMM and SIMM, most other maturity model have not focused on providing a means for not only portraying the target state attributes but actually developing a transformation roadmap to achieve the desired target state of maturity from a given current state of maturity. Such models quantify the relative growth of certain salient aspects within various dimensions typically within, but not limited to organizational boundaries.

A maturity level is defined by a set of characteristics or capabilities which can be measured and assessed within a domain of interest. A well known maturity model is the Software Engineering Institute’s Capability Maturity Model for Integration (CMMI) (See http://www.sei.cmu.edu/cmmi/). OSIMM is another maturity model.

A Maturity Model is also useful to understand the current level of an organization, as measured against a standard set of definitions and to help the organization understand what they gain and what business goals are achieved by moving to a higher level of maturity.

In summary, the Service Maturity Models help you:

  • Understand the value of implementing services
  • Assess an organizations level of service maturity
  • Determine the desired level of service maturity needed to achieve a business goal
  • Help identify a road map for achieving the desired service maturity goal state

What is the Service Maturity Model?

The Open Group Service Integration Maturity Model provides corporations and IT practitioners a means to assess a corporation’s service maturity. It provides a process to create a roadmap for incremental adoption of services which maximizes business and IT benefits at each stage along the way. The model consists of seven levels of maturity and seven dimensions of consideration within an organization or scope defined by the project. These act as a quantitative model to provide a means for assessment of a current state and agreement on the attributes needed in a future state within any one of the dimensions (business, governance & organization, method, application, architecture, information, infrastructure & management).

By leveraging the IBM SIMM Service maturity model, a key asset in IBM’s SOA services portfolio, as a starting point for standardization, IBM is able to help customers in various industries gain a greater understanding of their current and future maturity and to facilitate moving the SOA agenda forward.

What is SIMM?

IBM developed groundbreaking techniques that facilitate the SOA journey in terms of a maturity model. These techniques should be considered and utilized by any organization seeking to improve their business flexibility; making IT an accelerator rather than an inhibitor. Describing SIMM or OSIMM as an SOA Maturity model is correct but at the same time it is more than an SOA maturity model. OSIMM is a model for using services as the major structuring element for increased business flexibility, hence the term service integration maturity model. IBM has extensive experience in helping customers assess their maturity and articulate their roadmap for their SOA journey.

SIMM, the basis of OSIMM, is unique as a maturity model and different from CMMI based models because it focuses beyond just process improvements and it links the desired business outcomes to the maturity level across multiple dimensions. The differences between SIMM (and therefore also OSIMM) and other maturity models can be summarized as follows:

  • SIMM addresses areas of how business and IT interact, organization and governance, methods, applications, architecture, information and infrastructure & management,
  • SIMM does not produce just a single numerical result as a result of an assessment; you also get a series of action items that if implemented should improve an organization in the various domains, holistically, necessary to achieve a specific business outcome,
  • SIMM provides multiple results across different dimensions of assessment; as not all dimensions will score the same
  • SIMM does not assume that a higher maturity is necessarily better (good for your organization) for a given dimension; for example, only a subset of your application portfolio may need to move to SOA as a priority
  • SIMM does not advocate or require a linear movement from one maturity level to the next. It is possible and sometimes advisable to “jump” to an appropriate level; should the necessary pre-requisites be in place. This is made possible because SIMM focuses on process and results across multiple domains allowing visibility into each maturity stage (e.g., best practices) and its corresponding benefits.

One of the basic principles underlying SIMM is that assessing maturity requires a focus on people, process and technology and actual achievement of results. SIMM focuses on an organization’s transformation towards a service oriented enterprise. It focuses more on the results and benefits of achieving a level versus solely improvement of the process.

SIMM addresses the necessary business transformation that drives SOA adoption which in turn compels an organization or line of business to assess its current maturity and progress in the path to achieve the benefits of service orientation.

SIMM attributes and indicators help diagnose and baseline the current maturity level, define the future state, identify the gaps and leverage the attributes and indicators of the higher maturity level to develop the roadmap to attain the end state.

SIMM enables IBM to help clients understand their current maturity level, work with them to determine the future capabilities required, appropriate for the client based on their plans and aspiration, and then help them define a set of state transitions (or stepping stones) to get to their future state. SIMM can also addresses service orientation adoption from an enterprise architecture perspective and aid the evolution of increasing business and IT flexibility over time.

All of these things that are true for SIMM, are also true for OSIMM, since it is a direct derivative of SIMM.

Why is a roadmap approach to SOA better than just getting it done once and for all?

A SOA roadmap is incremental and allows a company to deploy SOA iteratively, deriving value from each step along the way. ‘Big bang’ deployments of SOA are much riskier because the SOA solution can not be adjusted during each iteration and it is much more likely that key requirements and business objectives may be been missed, leading to a SOA solution that fails to meet business objectives . Big bang deployments also incur all of the expense of deployment up front before any business benefit is realized or allow corrective actions to decrease the impact of risk on funding, resources and outcomes.

More importantly, OSIMM allows an organization to pick their desired level of maturity based on a set of attributes that align with the business goals of the organization. For example, seeking business process flexibility may be desired to improve time to market and to enable an organization to prepare for change. This may be suitable for only some lines of businesses and for only certain types of applications. Another organization may seek simply to reduce cycle times for a set of business processes. Other organizations may have partner collaborations which require integration flexibility. In each of these three scenarios, SOA is the preferred approach, but the level of maturity required differs. Because the level of maturity differs so does the roadmap or blueprint for achieving this business outcome: business process flexibility, partner integration flexibility or reduction of cycle times of a business process. SIMM provides the detail content to both understand the differences as well as the blueprint for bringing about the business outcome.

What is the relationship between this Service Maturity Model and SOA?

OSIMM as a Service Maturity Model allows organizations; architects and business stakeholders to see SOA not as a binary choice but as a continuum of measurable outcomes, where, depending on what business benefit is sought, the organization can plan and implement a series of actions to reach the desired maturity and therefore the desired business outcome.

Is this a SOA maturity model?

Services maturity need to assess more than SOA. Services can be realized though a combination of SOA, organizational governance, enterprise architecture and cloud based operational environments. OSIMM provides a holistic approach to service adoption and integration across an organization's business processes.


What are the Maturity Levels?

The level of de-coupling and amount of flexibility achievable at each stage of maturity are what make up the following seven levels of maturity:

  1. Silo (data integration)
  2. Integrated (application integration)
  3. Componentized (functional integration)
  4. Simple services (process integration)
  5. Composite services (supply-chain integration)
  6. Virtualized services ( virtual infrastructure)
  7. Dynamically reconfigurable services (eco-system integration)

Each level has a detailed set of characteristics and criteria for assessment, and what follows is a brief description of the highlights of each level:

Level One: The organization starts from proprietary and quite ad-hoc integration, rendering the architecture brittle in the face of change.

Level Two: The organization moves toward some form of EAI (Enterprise Application Integration), albeit with proprietary connections and integration points. The approaches it uses are tailored to use legacy systems and attempt to dissect and re-factor through data integration.

Level Three: At this level, the organization componentizes and modularizes major or critical parts of its application portfolio. It uses legacy transformation and renovation methods to re-factor legacy J2EE or .NET-based systems with clear component boundaries and scope, exposing functionality in a more modular fashion. The integration between components is through their interfaces and the contracts between them.

Level Four: The organization embarks on the early phases of SOA by defining and exposing services for consumption internally or externally for business partners -- not quite on a large scale -- but it acts as a service provider or service consumer, nonetheless.

Level Five: Now the organization extends its influence into the value chain and into the service eco-system. Services form a contract among suppliers, consumers, and brokers who can build their own eco-system for on-demand interaction. Often the simple services of level four are replaced by composite services that can be choreographed. More mature service meditation infrastructure is in place.

Level Six: The organization now creates a virtualized infrastructure to run applications. It achieves this level after decoupling the application, its services, components, and flows. Now the infrastructure is more finely tuned, and the notions of the grid and the grid service render it more agile. It externalizes its monitoring, management, and events (common event infrastructure).

Level Seven: The organization now has dynamically re-configurable software architecture. It can compose services at run-time using externalized policy descriptions, management, and monitoring.

What are the Dimensions?

An organization’s level of service maturity can be assessed across the following set of dimensions which are essential indicators for effective service and SOA adoption. The breadth of these dimensions covers the breadth that SOA and governance practices apply to an enterprise.

Business: The Business dimension is focused on the business architecture: i.e. the organization’s current business practices and policies, how business processes are designed, structured, implemented and executed. The Business dimension also includes IT strategy and addresses the cost and flexibility of IT capabilities, business agility and service-level agreements.

Organization & Governance: The Organization & Governance dimension is focused on the structure and design of the organization itself and the necessary measures of organizational effectiveness as well as the means of governing that organizational structure especially in the context of an SOA.

Methods: The Methods dimension is focused on the methods and processes employed by the organization for its IT and business transformation. This includes the maturity of the software development life-cycle, software engineering practices and guidelines used for the design and development of a SOA.

Applications: The application dimension is focused on application style, structuring of the application and functionality of the underlying applications including the attributes of reusability, flexibility, reliability and extensibility of the applications.

Architecture: The Architecture dimension is focused on the structure of the architecture style which includes use of reference architectures, logical and physical topologies, integration techniques and patterns, enterprise architecture decisions, standards and policies, web services adoption level, experience in SOA implementation, SOA compliance criteria, and typical artifacts produced.

Information: The Information dimension is focused on how information is structured, maintained, cleansed and how information is modeled, the method of access to enterprise data, abstraction of the data access from the functional aspects, data characteristics, data transformation, service and process definition, handling of identifiers, security credentials, knowledge management, business information model, and content management including the mechanisms for integration of information across the enterprise.

Infrastructure: The Infrastructure dimension is focused on the organization’s infrastructure capabilities including service management, IT operations, IT management and IT administration, SLA compliance, how monitoring is performed, and what types of integration platforms are provided to support the other dimensions that rely on the infrastructure to deliver the necessary capabilities to enable the SOA as well as other legacy systems participating within the eco-system.


What’s the process for doing an Assessment?

The OSIMM standard defines a set of maturity indicators for each dimension that can be used to test maturity. Each maturity indicator is accompanied by a set of attributes for each level in the dimension. A set of questions are provided that can help understand which attributes apply for the company.

The maturity model can be customized and extended by adding maturity indicators and attributes appropriate for the industry or organization.


How are SOA Roadmaps defined?

First you do an assessment of your current environment, and then envision the environment you would like to have and is necessary to be put in place to accomplish your business objectives.

Analysis consists of the following three activities:

  1. Assessment of the current maturity levels of the business, organization and IT.
  2. Determine the goal state maturity levels by considering the required 'level of service and SOA maturity necessary to achieve the stated business goals.
  3. Compare the current and target level maturity indicators to identify gaps and determine the organization’s transformation roadmap from current maturity to desired target maturity level.

In fact you can also define interim levels of maturity: what is the next major maturity goal, defining roadmaps to attain each of these goals with clear business value. This allows the company to see progress and enjoy some of the business values along the way.

Are Assessments difficult?

Assessments are often a subjective art and a developed skill. The first assessment of the current environment can be time consuming as stakeholders and information is identified and gathered for the first to support the assessment and ask the questions. Maturity models are a complex topic and you may need interpretation of OSIMM in context of your environment. Scoring of an assessment can be an art and should be done based on an unbiased understanding of your organization in comparison with other similar organizations. The recommendation for increasing objectivity is to include a number of participants who provide input from different vantage points within the organization. This will decrease bias through wider inclusion and provide more accurate results.

IBM developed a Capability Assessment Tool (CAT) at IBM Research. CAT is an end to end framework to create and exploit IBM's intellectual expertise through the development and use of capability model assessment assets as client deliverables to assess and understand our customer’s needs. IBM has several capability and maturity models for which CAT provides tool support. CAT has several differentiating features which include:

  • Automated analysis and roadmaps
  • Separation between model design and analysis artifacts
  • Role based facility for governance and access control
  • Common repository enabling benchmarking and connecting results across offerings
  • Ability to do time based analysis to show measure growth or success

SIMM is a maturity model that has been set-up in the CAT tool and used by hundreds of clients all over the world. IBM uses the CAT tool to perform quick surveys to understand both current and desired state of SOA adoption. Engagements can be set-up to allow client based surveys with IBM hosting the tool and providing access ids.

With all of the client responses stored in the database, the engagement lead can now use the CAT analysis tool to load the collective set of client’s results, view basic statistical results, analyze the data, and export diagrams and data for deliverable creation.

Since all the data gets stored in the single repository, the results from a given engagement can be used again, either as a time sequence when the assessment is performed again at that same client, or as part of a benchmarking exercise. Subsequent assessments may be less resource intensive because the assessor and the organization understand the process and information needed to conduct an assessment.

You can test drive this using a preliminary SOA self assessments available to help you determine your readiness to start your SOA journey and your opportunities for improvement. Answer a short set of questions based on our standardized services maturity model (OSIMM) to assess your SOA capabilities and take stock of where you are and where you would like to go with SOA at http://www-01.ibm.com/software/solutions/soa/soaassessment/index.html.

The instant online results will also provide you with:

  • Your company's current state and next steps toward improving your SOA level of adoption described in clear, straight-forward terms.
  • The benefits and advantages you can access right now with your existing integration infrastructure.
  • Recommendations for moving to the next level of service and SOA maturity to achieve greater business flexibility through greater adoption of service oriented approaches.

The IBM SOA assessment tool can help you unlock the full value of SOA. Keep in mind this is not the full SIMM or OSIMM assessment but an abbreviated self-assessment based on OSIMM and SIMM content.
