    This paper focuses on the importance of Enterprise Architecture (EA) and how it helps to coordinate business and technology programs across a company. Enterprise architecture involves the practice of analyzing, planning, designing, and ultimately implementing analysis of an enterprise. The goal of enterprise architecture is to determine how effectively an organization can achieve its current and future goals.
    This paper defines enterprise architecture as four elements. There is business process architecture, which includes data or information architecture, application architecture and technology architecture.

    Information systems provided by third parties continue to evolve with new features and implementation strategies. The complexity and diversity of available options make it difficult for many companies to fully discuss and compare alternatives that may or may not meet their requirements.
    Third parties often promote architectures that are supported by products or solutions in a company’s or an individual’s toolbox. If a company does not have a clear vision for the architecture of its operating system, it will often adopt a vendor’s approach. This approach may be best suited to systems under development; However, in many cases this is not the case.
    In the absence of a targeted “future” architecture, adopting a third-party vendor approach is inevitable. With the increasing reliance on system agility and associated operational management capabilities, the need to raise standards is clear. Companies must be able to understand their production processes and structures as a basis for actual process improvement. Once understood, the status quo and target future architecture will serve as a common basis for discussing and mapping alternatives.

    Ross, J.W., Weill P., and Robertson D.C. (2008), “Implementing the Operating Model via Enterprise Architecture” is a seminal article that discusses the importance of enterprise architecture (EA) in implementing an organization’s operating model effectively. The authors emphasize the need for alignment between an organization’s strategic goals, its operating model, and its IT infrastructure. They argue that enterprise architecture serves as a bridge between business strategy and IT capabilities, helping organizations translate strategic objectives into operational processes and technology solutions.

    I think the key point is the importance of enterprise architecture, the purpose of which is to determine how effectively an organization can achieve its current and future goals. This article introduces four different EA models that can be applied to other enterprises, industries, and different situations. In order to survive and develop, enterprises must constantly adapt to changes in the environment and meet the environmental requirements of the organization. Therefore, the environment is a key factor in determining which type of enterprise architecture an administrator adopts

    This article extensively explores how enterprise architecture plays a crucial role in practice, particularly in translating strategic goals into actionable operational processes and technology solutions. I find the authors’ viewpoints highly compelling, as in today’s digital age, organizations must be able to marry strategic goals with IT capabilities to achieve business transformation and growth. Furthermore, the article underscores the importance of closely aligning enterprise architecture with organizational strategic goals.

    The discussion following “Who Should Design Enterprise Architecture?” in this reading caught my attention. The authors highlight the creation of enterprise architecture by a small team using various diagrams to connect existing systems, aiming to reduce overall complexity. However, many of these diagrams only suggest a reduction in complexity without leading to tangible implementation. The authors suggest that having senior management design and implement enterprise architecture is more beneficial. This approach reduces costs significantly through effective reusability and simplified processes, making it a more effective method than having a small IT team design it.

    A key point made in the Implement The Operating Model Via Enterprise Architecture article was that the enterprise architecture process should start with senior management and not by lower-skilled IT employees. Creating an operating model should be a decision made from an overview perspective instead. Some important business processes should be identifying such as the key clients, data sharing components, and core processes. The article describes enterprise architecture as an essential management tool for aligning technology and business objectives.

    One of the main points I took away from this article is that it is important to understand the enterprise architecture before building an IT architecture. The four architectural layers of enterprise architecture:
    1. business process architecture – the activities or tasks that make up the major business processes as defined by the business process owners.
    2. data or information architecture – shared data definitions.
    3. application architecture-the individual applications and their interfaces.
    4. technology architecture-the infrastructure services and the technical standards on which they are based.
    Enterprise architecture and enterprise architecture are complementary. Both reflect the integration and standardization requirements of a company’s operating model, and a high level of enterprise architecture enables its departments to develop solutions that meet long-term needs. When a department tries to create a detailed architecture without a clear understanding of its enterprise architecture, it is a decoration, not a tool, for the company.

    A key point is that senior management must discuss the entity’s operating model to clearly identify core processes, shared data, and technologies for developing an integrated enterprise architecture. Staying within the confines of the operating model will allow companies to build a better foundation that will allow them to adapt to new regulations, laws, technologies, or business goals over time.

    The article discusses the importance of enterprise architecture and the different architectural designs that are successfully built around an organization’s operating model. Enterprise architecture is what ensures that an organization has the ability to achieve its goals. However, it is often mistaken for IT architecture, which is different in that the latter is about ensuring that the system’s solutions meet the organization’s business needs. Although the design of enterprise architecture starts at the top of the organization and is usually not developed by non-technical people. However, it is important to consult with them because they can provide detailed information about customers, how certain business processes work, and what data is needed to drive those processes. The article describes the enterprise architecture of four companies and the steps taken to achieve their goals. I believe that the industry and operating model of a business will have an impact on the achievement of the end goal, but there is no right or wrong way to design an enterprise architecture as long as it is built to achieve the goals of the business.

    One of the key points I took away from this reading was the importance of understanding enterprise architecture before building IT architecture. As the reading material notes, “When IT departments try to develop detailed architectures without a clear understanding of a company’s enterprise architecture, they may have developed the equivalent of hotpots and decorations instead of tools.” From my perspective, this ultimately means that organizations need to align their IT infrastructure with business goals. In this process, IT is important to choose the right operating model based on the current IT infrastructure and organizational layout, including customers and all other stakeholders.

    The significance of enterprise architecture lies in its ability to determine the effectiveness with which an organization can achieve its current and future goals. As enterprises strive to survive and develop, they must constantly adapt to environmental changes and meet the organizational requirements of their respective industries. This underscores the importance of considering the environment as a crucial factor in determining the appropriate type of enterprise architecture to adopt. Furthermore, the implementation of an operating model through enterprise architecture emphasizes the need for senior management involvement, rather than relying solely on lower-skilled IT employees. This top-down approach ensures that key business processes, such as identifying critical clients, data sharing components, and core processes, are addressed from an overview perspective. Enterprise architecture, therefore, serves as an integral management tool for aligning technology with business objectives, facilitating decision-making and driving organizational success.

    This article discusses how enterprise architecture plays a key role in practice, and the author proposes the need for alignment between an organization’s strategic goals, operating model, and IT infrastructure. This will benefit the development of the business growth. Of course, the key factor in the choice of enterprise architecture is the market environment of the enterprise, because the author also proposes that the enterprise architecture and the strategic goals of the organization are closely linked.

    The structure of all enterprises will not be completely consistent, according to the characteristics of the industry and the cultural accumulation of the enterprise itself will have its uniqueness, but the large framework of the industry is certainly the same.

    First of all, I realized that it is definitely critical for any company to have well defined Enterprise Architecture and IT model after reading this article.
    There are 4 common elements in Enterprise Architecture diagrams:
    1. Core Business Processes
    2. Shared Data Driving Core Processes
    3. Key Linking and Automation Technologies
    4. Key Customers
    Interestingly, while companies tend to incorporate the same elements into their enterprise architecture models, these companies will focus on and emphasize different elements in ways that best support their business style. MetLife, for example, uses the Coordination EA model, which focuses on key customers because of the business’s “wide range of unique products.”

    Define Business objectives: First, you need to define the core business objectives of the organization. These goals should be clear, measurable and achievable.
    Analyze business processes: Analyze business processes within an organization to understand the collaboration between departments and employees, as well as key nodes and decision points in the process.
    Design operational model: Design an operational model based on the results of business process analysis. The model should include the various departments and employees within the organization, as well as the collaboration between them, the allocation of responsibilities, resource utilization, and decision making.
    Develop an implementation plan: To ensure the effective implementation of the operational model, a detailed implementation plan needs to be developed. The plan should include things like timetables, resource allocation, training plans, etc.
    Implementation operation model: Implement the operation model step by step according to the implementation plan. This may require communication and coordination with departments and employees to ensure they understand and follow the new way of operating.
    Monitoring and optimization: After the operational model is implemented, it needs to be continuously monitored and optimized. Collect and analyze data to understand the health of operational models, identify problems, and make improvements.
    Implementing operational models through enterprise architecture can help organizations better understand and optimize their internal operational processes, improve efficiency and quality, and achieve business goals. At the same time, operational models can also provide an organization with a clear frame of reference to help departments and employees understand their roles and responsibilities in the organization and how to collaborate with other departments and employees.

    When designing an enterprise architecture, it is important to consider the organization’s operating model and its goals. Enterprise architecture “is the organizational logic of business processes and IT infrastructure, reflecting the integration and standardization requirements of the company’s operating model”. Staying within the scope of the operating model will enable companies to build a better foundation that enables them to adapt to new regulations, laws, technology, or business objectives over time

    I understand how organizations plan, design, and develop enterprise security architecture to align their IT security capabilities with their business goals and strategies, and evaluate IT system security architecture and capabilities. Thinking about security architecture enables us to understand enterprise information systems like attackers and implement deep defense against assets.
    It provides a comprehensive set of guidelines and principles, as well as a method for identifying and analyzing the various components that make up the model, a framework for monitoring operational model performance, and an information and resource sharing platform for communication and coordination among different stakeholders involved in implementing the model.

    The article focuses on the importance of building an enterprise architecture for your company. Enterprise architecture is the organizational logic of business processes and IT infrastructure that reflects the integration and standardization requirements of a company’s operating model.
    In the Enterprise Architecture Core Diagram, we can observe four common elements: core business processes, shared data-driven core processes, key links and automation technologies, and key customers. And these elements are usually based on the company’s operating model. So in the process of building an enterprise architecture, management must decide what is really at the core of the company, and the company will populate the Enterprise Architecture Core Diagram on that basis.

    I believe that enterprise IT architecture and operations, encompassing information technology governance integrates the tools, processes and methodologies that enable organisations to ensure that business strategies and objectives are aligned with IT services, infrastructure or environment.
    IT governance is the use, management and optimisation of IT to support, complement or help the organisation achieve its aims and objectives.
    In exploring corporate governance, Weil and Robertson identified six key assets that need to be governed through which organisations can successfully execute their strategy and create business value. The six key assets are: human assets, financial assets, physical assets, intellectual property (IP) assets, information and IT assets, and relationship assets. According to their theory, “senior management teams need to create mechanisms to govern management and use these assets individually and collectively. Governance of key assets is carried out through a large number of organisational mechanisms, such as structures, processes, procedures and audits. In the current digital environment, governance of IT assets is increasingly important to ensure that IT is used to create value while managing business risks.

    One key takeaway is that it is imperative for senior management to discuss the entity’s operating model to clearly identify core process, shared data and technologies in developing an integrated enterprise architecture. If done solely by IT subject matter experts, chances are it may lean towards capturing complex systems, instead of an integrated architecture model that reflects and aligns the entity’s business and IT plans.
