Enterprise Architecture

Enterprise Architecture

TCrest is experienced in the practice of planning, designing and executing the elements of business strategy, business case, business model and supporting technologies, policies and infrastructures that make up an enterprise.
We also involve in developing an Architecture Framework with a series of "current", "intermediate" and "target" reference architectures and applying them to align change within the enterprise.
The architecture process addresses documenting and understanding the discrete enterprise structural components including
  • Business
  • Application
  • Information
  • Security
  • Technology
    • Infrastructure
    • Platform

We provide end to end architecture services that include

  • Business and Process Architecture
  • Information and Data Architecture
  • Technology and Network Architecture
  • Application Architecture
Our consultants are experienced and knowledgeable in many architecture frameworks including TOGAF (The Open Group Architecture Framework), Zachman, FEAF (Federal Enterprise Architecture Model), DoDAF (The USA Department of Defense Architecture Framework), and many other standard models.

Infrastructure Planning and Refresh

We also provide an overall assessment of the existing infrastructure, document all the hardware and software, provide AS-IS model and derive the future Infrastructure based on the customer requirement.

The fundamental characteristics of Enterprise Architecture (EA) can be described as follows:

  • EA is a holistic approach to documenting and managing an enterprise’s current and future states in terms of strategy, business processes and technology.
  • The adoption of EA can enable enterprises to make informed decisions and to implement the decisions as efficient as possible.
  • In governance, an EA program needs to address the dynamic and political nature of enterprises thereby making EA a pragmatic, organizational exercise.
  • The distinction between making decisions and implementing them is especially important from a strategic perspective. This stresses the dual purpose of EA to enable enterprises to:
    • Do the right things (strategy)
    • Do things right (operational effectiveness)

Purpose of Enterprise Architecture

The purpose of EA is the greater alignment between IT and business concerns. The main purpose of enterprise architecture is to guide the process of planning and designing the IT/IS capabilities of an enterprise in order to meet desired organizational objectives.

Benefits of Enterprise Architecture

The enterprise architecture benefits include: more efficient business operation with lower costs; more shared capabilities; lower management costs; more flexible workforce; more organization; less duplication and redundancies; and improved business productivity.

Benefits of Adopting an EA Framework

An enterprise architecture framework (EA framework) defines how to create and use enterprise architecture. An architecture framework provides principles and practices for creating and using the architecture description of a system.  Examples include TOGAF, DoDAF, FEAF, and Zachman.

Benefits of Adopting the TOGAF Framework

An effective Enterprise Architecture can bring important benefits to the organization. Specific benefits of an Enterprise Architecture include:

More effective and efficient business operations:

  • Lower business operation costs
  • More agile organization
  • Business capabilities shared across the organization
  • Lower change management costs
  • More flexible workforce
  • Improved business productivity

-More effective and efficient Digital Transformation and IT operations:

  • Extending effective reach of the enterprise through digital capability
  • Bringing all components of the enterprise into a harmonized environment
  • Lower software development, support, and maintenance costs
  • Increased portability of applications
  • Improved interoperability and easier system and network management
  • Improved ability to address critical enterprise-wide issues like security
  • Easier upgrade and exchange of system components

-Better return on existing investment, reduced risk for future investment:

  • Reduced complexity in the business and IT
  • Maximum return on investment in existing business and IT infrastructure
  • The flexibility to make, buy, or out-source business and IT solutions
  • Reduced risk overall in new investments and their cost of ownership

-Faster, simpler, and cheaper procurement:

  • Buying decisions are simpler, because the information governing procurement is readily available in a coherent plan
  • The procurement process is faster – maximizing procurement speed and flexibility without sacrificing architectural coherence
  • The ability to procure heterogeneous, multi-vendor open systems
  • The ability to secure more economic capabilities

How do our business objectives contribute to the organizational IT strategy?

Assessing whether specific objectives are actually contributing to the organizational strategy can be difficult. Regardless, it’s an important aspect of deciding on future changes to the company’s goals, which means business analysts are often confronted with this question by upper-management.  EA frameworks greatly facilitate determining the degree of alignment between the objectives and the organization’s strategy.

How effectively was the strategy implemented?

The importance of strategic planning is paramount, if an organization is to develop successfully. Therefore, it is equally important to identify how well a strategy is implemented if management’s assessments are to be based on facts. An EA Framework highlights the relationships between capabilities, roles, skills and measures by the means of specific organizational views.  You will be able to more quickly identify the facts you need to author reports that answer those questions clearly, and in a timely and actionable response.

What programs are currently live across the entire organization?

Many enterprises have reached such a high degrees of complexity that it is a unique challenge to keep accurate track of all the projects, systems and resources that are “in motion” at any one time.  IT leaders are confronted with the need to answer to management and business owners about on-going and future processes on a routine basis. To help you deal with these top-down requests, an EA Framework provides you with diagrams that detail program implementations across the organization and showcase what capabilities will be delivered, along with the objectives and resources needed to deliver them.

How will planned changes impact our broader enterprise?

In support of decision making, you will be required to identify a certain decision’s impact on the wider enterprise. In other words, you’ll be relied upon to run a “proof test”. This can be very challenging because it requires to accurately follow the line of causality in what can be an extremely cluttered environment. An EA Framework will allow new monitoring capabilities that will ensure you get the job done right, and with minimal effort..

How can we better manage the myriad investments of our IT resources, systems, and projects?

Large organizations have multiple IT Teams working simultaneously on many systems, data, projects and services within the enterprise.  An EA framework, along with the combination of EA Tools an artifact Repository for all operational and planned resources, can ensure that various teams may develop, share and re-use IT constructs across the enterprise, by the use of consistently defined EA constructs and views.

Can we eliminate a certain application to cut costs?

Organizations often have duplicate systems, purchased because people were unaware of existing resources, or inherited as a result of a merger or acquisition. Your EA Framework will provide a complete, up-to-date view of the application landscape, enabling users to quickly and easily identify redundant or duplicate applications, greatly reducing overall operating costs.  EA will also instantiate defined and consistent organizational processes for the future acquisition of software, hardware and services.

Can we migrate some applications to the Cloud?

As organizations begin to consider leveraging the services and infrastructure value of hosting their applications and systems in a cloud environment, an important question that arises is which application(s) should we move to the Cloud? This decision is usually not made on a single factor alone. The choice of which applications to move (and not move) to the cloud should be based on a thorough analysis of your IT landscape, the exercise is called the Cloud migration process.  Common challenges an enterprise faces during a cloud migration include interoperability, data and application portability, data integrity and security, and business continuity.  Your EA Framework will provide the perspective and best path for this process.

How can we better leverage our data assets as an organization?

An EA Framework establishes a number of views across your organization’s business and technology assets..  One of these is the Information View, or Data Architecture.   EA seeks to establish a common data view across all data stores, providing a logical data model that serves all projects and systems, and reduces the “silo effect” of standalone systems.  Maintaining a common enterprise data architecture will facilitate establishing the “record(s) of truth” across your data collections, and become the baseline for how your organization can marshal the power of its collective information for providing business greater intelligence and analytics.

How do we ensure data traceablility?

An EA Framework enables users to define how data is to be stored, consumed, integrated and managed by different data entities, processes, and IT systems. This makes it easy for different stakeholders to understand exactly what data is generated, how and where it is stored, and who accesses it.

How can we better align our IT resources for efficiency and consistent re-use across our organization?

Over time, most organizations have amassed an extensive collection of data, platforms, systems and infrastructure, wherein analysis reveals there’s no common thread or logic to this collection.  An EA Framework enables an organization to define standards for the enterprise, governing the number of different platforms, differing code bases and/or data types are employed and managed by the enterprise.  An EA Framework will guide your organization’s development roadmap along the way to retire legacy systems, migrate systems to shared or common infrastructure, or to hosted cloud platforms, thereby reducing redundancy, variation and inefficiencies across the IT environment.
