Enterprise Architectures
The practice of Architecture involves planning, designing, integrating,
and managing complex systems of systems that can evolve to support changes
in business needs and advances in software and information technologies.
This area addresses the integration and interoperability of COTS components
with custom-developed and current operational ("legacy") components.
This area also seeks to define and measure the attributes of a good architecture.
The use and evaluation of application integration approaches such as Microsoft's
.Net, Sun's Java 2 Enterprise Edition, and the OMG Model-Driven Architecture
fall into this area.
MITRE Enterprise Architecture End-user Vision, "The Amanda Story"
Donna Cuomo, Principal Investigator
Location(s): Washington and Bedford
Problem
Follow Amanda and her team through a series of typical team-related tasks that most MITRE users need to perform in the course of their daily work. The story and related demonstrations illustrate how employees perform these tasks using today's available IT infrastructure and set of capabilities. The story then highlights how MITRE staff and our sponsors can perform these same tasks more efficiently and effectively, and what new capabilities employees will have as MITRE acquires the major pieces of the forward-looking Enterprise Architecture roadmap and puts them into production in the coming years. Learn how the new services offered via the flexible My MII portal infrastructure can help with managing projects and federating content, how integrated messaging and calendaring will make scheduling people and resources more efficient, how Community Share improves both MITRE-sponsor collaboration and document management, and what new capabilities are in store for the mobile workforce.

Enterprise Transformation to Service Oriented Architectures: Case Studies and Unifying Framework
Marc Halley, Principal Investigator
Location(s): Washington
Problem
Service Oriented Architectures (SOAs) hold the promise of flexible enterprise software that can respond to rapidly changing needs. MITRE sponsors are preparing to invest billions in the necessary components of SOAs. However, transformation is expensive, complex, and risky. MITRE sponsors need an integrated framework which that provides empirically based guidance for enterprise transformation to a Service Oriented Architecture.
Objectives
This project will develop the integrated framework to guide the transformation to an SOA. From case studies of 10 large enterprises and their attempts at transformation, we will create a framework which will guide enterprises in their transformation. The framework will integrate the most important components of the transformation: economics, governance, architecture, portfolio, risk, change management, and technology management.
Activities
We will conduct case studies of ten large organizations that have attempted, or are in the process of, transformation to SOAs. We will derive patterns and success criteria and then develop a framework integrating the six transformation components. The results and the framework will be published as a volume of the new MITRE Series on Enterprise Modernization.
Impact
According to market research, 80% of large organizations are predicted to start major SOA initiatives during 2005 and 2006. This research will have immediate impact on the strategic direction and implementation of SOAs by MITRE sponsors. A guidance framework should save our sponsors millions of dollars by improving their chances of successfully and efficiently implementing a Service Oriented Architecture.

Multi-Agency Executable Architecture Case
Study—Federal, State, and Local Interactions
Tom Pawlowski, Principal Investigator
Location(s): Washington
Problem
As federal agencies develop architectures for information technology (IT) systems, dynamic analyses are needed to determine system performance and effectiveness. Agencies that must interoperate are unlikely to use the same tools and frameworks to capture their IT architectures. The challenges are to ensure satisfactory interoperability, determine that the mission will be accomplished, and eliminate critical gaps among the architectures.
Objectives
We will examine the challenges and issues associated with interoperability and information sharing when multiple agencies, represented by different architectures built with different architecture frameworks, must function together to accomplish a mission. To address issues associated with multi-agency operations we will use a case study involving architectures from a DoD agency and a DHS agency executing a homeland security mission.
Activities
The work will apply the products and techniques developed in two related research projects: Multi-Agency Planning Framework and Executable Architecture Methodology for Analysis. We will select a homeland security scenario and multi-agency mission to be accomplished by DoD and DHS organizations, capture the architectures in an executable form, run them as a federation of simulations, and extract appropriate measures of performance and effectiveness.
Impact
We will improve the utility of architectures across the government by allowing them to be examined in an integrated and dynamic mode. Architectures will be assessed for connectivity, information flow, and performance in their operational environment. Cost factors can be examined to facilitate resource allocation. These capabilities will benefit agencies trying to justify their budgets and investments to OMB and Congress.

Multiagency Enterprise Architecture Planning Framework
Ken Hoffman, Principal Investigator
Location(s): Washington and Bedford
Problem
The integration and allocation of information resources and physical assets of multiple agencies are critical problems in many national programs: homeland security, border control, trade, counter-narcotics, health and safety, and e-government services. The scope and complexity of this environment go well beyond those of single agencies and require new approaches to modernization programs.
Objectives
This project will identify the critical requirements of multi-agency modernization planning. It will also identify, evaluate, and improve the capabilities of planning tools and methods. Special attention will be directed at architectures, activity models, and other tools for application to multiagency strategies and planning.
Activities
Tasks include identifying multi-agency governance and technical complexities that impose unique requirements on architectures. A next-generation mission-centric architecture concept is under development to complement the enterprise architectures of agencies joined in mission or service activities, as are methods to support modernization. The results are being incorporated in a workbench and toolkit using activity-based planning and dynamic modeling in a geographic context.
Impact
This research will enable MITRE to select the most appropriate tools and methods and apply them to the full spectrum of multiagency mission and service programs. Research results may be applied to multiagency program offices to help them focus on mission activities while drawing support from the participating agencies, and may also be incorporated in the Federal CIO Council Guidance (OMB).

Node Information Services—Joint Process Integration
Robert Wilson, Principal Investigator
Location(s): Washington and Bedford
Problem
Loosely coupled mechanisms such as Web services can be codified as design patterns to accelerate horizontal integration of C2 and ISR systems. However, without suitable research that can identify a reusable set of patterns, disparate solutions will probably emerge that will slow progress toward an enterprise of interoperable C2 nodes.
Objectives
We will identify a set of design patterns based on priority operational needs and deliver a catalogue of patterns that will enable interoperable solutions across C2 nodes (e.g., air operations center, Distributed Common Ground System, Multisensor C2 Aircraft). We will document the results of our research on the process of pattern identification, codification, and application to C2 systems.
Activities
We will identify patterns based on high-priority operational needs (e.g., disconnected operations), investigate commercial and non-commercial solutions that lend themselves to pattern codification, build both atomic and composite patterns, specify a pattern representation model, and document patterns in a catalogue with code examples. We will also partner with industry to leverage solutions outside MITRE and report our research findings.
Impact
Patterns will accelerate the horizontal integration of C2 and ISR systems by codifying interoperability solutions based on Web services. They will also provide a platform-independent basis for evaluating contractor-proposed interoperability solutions, enable cost-effective design reuse across C2 and ISR programs, and influence vendors and their products by articulating the types of solutions needed by the Air Force and DoD.
