| Enterprise Level Architecture Consulting
Enterprise-level, architecture-based information management
planning (EAP) is the most successful approach to planning
and executing an IT strategy in complex, multi-platform enterprise
situations.

| The business benefits
of an IT architecture are:
- Better decision-making and planning.
- Better communication among organizations
and IT organizations within the enterprise
- Increased focus on the strategic use of emerging
technologies to manage the enterprise's information
- Increased consistency, accuracy, timeliness,
integrity, quality, availability, access and sharing of
IT-managed information across the enterprise
- Ability to highlight opportunities for building
greater quality, scalability, and flexibility into applications
without increasing cost
- Achieving economies of scale by providing
mechanisms for sharing services
- Expediting integration of legacy and new
systems and supporting migration of legacy applications

The key steps of
the Enterprise Architecture Planning method are:
- Enterprise
Architecture Definition
This phase focuses on confirming the scope and goals of
the architecture, identifying the sources of information
and the areas of subject matter expertise, creating a performing
team and environment, and establishing the decision making
process for the project.
- Architecture
Development
This phase focuses on documenting the existing situation,
envisioning the future situation, creating a transition
path from the existing to the future situation, and creating
artifacts, repositories, tools and processes that will support
the next phase, architecture usage.
- Architecture
Usage
This phase focuses on enacting the process, organization,
skills and methodology changes decided during the architecture
creation, as well as starting the execution of the transition
path.
- Architecture
Maintenance
This phase begins in parallel with the creation of the architecture
and continues throughout the lifecycle. It focuses on the
institutionalization of the architecture process, the transfer
of knowledge, and the creation of adaptive feedback processes
to inform the architecture development with the most recent
business changes.
