Critical Evaluation and Gap Identification

• Business Executive Perspective - There remains a strong tendency in today’s literature to emphasize solely the technical aspects of EA. There are many opportunities for more research that explains EA from the perspective of the business executive, demonstrating how they can use EA to drive business strategy and how EA can enhance executive decision-making.
• Practical Application of AI in EA - While there is a lot of discourse around how AI and ML can be implemented in EA, there is limited research and little literature review about practical applications and case studies that demonstrate the actual usage and real impact of these technologies on different areas of EA practices.
• Sustainability Metrics and EA - The role of EA in promoting sustainability is acknowledged only in theory, and detailed frameworks and methodologies that describe how an organization’s EA practice can be used to integrate sustainability metrics are scarce.
• Resource Optimization and Strategic Insights - What could EA teams do to increase their strategic sustainability or further enable them to infuse strategic insights to support business needs?

• Governance Architecture:
  • Governance Framework: This is a continuous effort whereby the principles, policies and guidelines of EA development, implementation and governance are formulated. It details the processes of decision making, roles and responsibilities, as well as accountability of the different functions concerned within the governance structure.
  • Governance Board: Includes stakeholders who oversee EA activities. Responsible for setting strategic direction, authorizing architectural decisions, ensuring EA is on track with the business, and to function as a neutral arbiter in conflicts.
  • Compliance and Audit: it consists of checking if technological operations comply with relevant legal regulations and industry standards; if there are any present risks; if they are controlled; regulating access to the system; and ensuring the protection of data (Whitman & Mattord, 2019).
  • Change Management: Keeps track of all changes to the EA, laying down rules for how such changes will be made and keeping change requests, impact assessments, maintenance decisions and their changes under control.
• Business Architecture:
  • Business Strategy: Describes the organization’s respective strategic direction and objectives; used to determine how business processes should be designed, and which capabilities should be fulfilled.
  • Business Processes: Activities, workflows, and interactions that define and enable an organization’s operation. Describe how work is completed and whom, what, where, when, why, and which relate to that process. Business architecture seeks to map and enhance business processes for improved efficiency, productivity, and customer value (Ross, Weill, & Robertson, 2006).
  • Business Capabilities: Capture the organization’s abilities to carry out its strategy and achieve its goals, as described above. Include which competencies, assets, technologies, and knowledge the organization possesses to perform certain business tasks.
  • Organizational Structure: Defines the hierarchical structure, reporting relationships, and responsibilities of the organization to facilitate the execution of business processes. Organizational Structure: Categorizes the design of organizational environments based on roles, responsibilities, and tasks to enable decision making, coordination, and collaboration within the organization (Laudon and Laudon, 2020). (Laudon & Laudon, 2020).
• Information Architecture:
  • Data Governance: Policies, processes, and procedures related to management of corporate data assets such as data quality management, data security, data integration, and data lifecycle management.
  • Data Models: Data model specifications of the conceptual/scheme model and the logical/physical data model, specify the structure (attributes of an entity), relationship, and constraints to be enforced for the respective functional model of a respective system. This is a conceptual and logical representation of the organization’s data, which allows for uniform maintenance of data.
  • Information Systems: Applications, systems, and technologies that support information capture, retrieval, and processing. Examples include databases, data warehouses, content management systems, and other information management tools.
  • Data Integration: Ensures seamless integration of data between two systems and applications. Data integration technologies, interfaces, and exchange protocols ensure interaction between different systems and produce a consistent and accurate reflection of the information landscape in the enterprise. It involves integration of data from all sources and systems and produces a unified view of information across the enterprise. (Ross, Weill, & Robertson, 2006).
• Technical Architecture:
  • Hardware and Infrastructure: The physical infrastructure of the organization consists of servers, networks, storage, and other hardware components required to support IT operations. Technical architecture: hardware, software, networks, and other infrastructure components required to support technology operations (Laudon & Laudon, 2020).
  • Software Systems: Applications, platforms, and software components that enable and support business processes and information management. These software components include enterprise resource-planning (ERP) systems, customer-relationship-management (CRM) systems, and other specialized software. It refers to the selection, integration and management of application systems that enable process and information management. (From Ross, Weill, Robertson, 2006, reprinted in IT Governance Handbook, Rosemann, 2008 - Ross, Weill, & Robertson, 2006).
  • Application Integration: Application-to-application or system-to-system integration to allow data communication and process automation. Examples include middleware, application programming interfaces (APIs), and service-oriented architecture (SOA) policies. This layer also manages selection, integration, and management of application systems to support business processes and data management (Ross, Weill, & Robertson, 2006).
• Security Architecture:
  • Security Policies:Governs the rules and procedures to be followed to protect an organization’s platform or critical infrastructure for information and technology assets. This can include details such as access controls, data privacy requirements, risk management methodologies, incident response protocols and compliance processes.
  • Security Controls:Refers to the technical and procedural controls used to protect the organization’s assets. These are typically firewalls, intrusion detection and prevention systems, data, and configuration encryption mechanisms, as well as authentication and authorization mechanisms, and security awareness training programs.
  • Data Protection:Data protection is required for defending the confidentiality of information from unauthorized access, or disclosure. This element acts like a shield towards third parties where information is encrypted, access controls are in place, as is data loss prevention, backup, and recovery (Kizza, 2016).
  • Security Monitoring and Incident Response: Security monitoring and auditing typically entails reviewing systems and networks for any signs of disturbance. This component comprises of real-time log analysis, intrusion detection systems, security event correlation, and frequent security audits (Whitman & Mattord, 2019).
• Human Capital Architecture:
  • Skills and Competencies:Assessment and development of needed skills and competencies to support the organization’s strategic goals, which entails defining the needs for job roles, assessing employees’ skill sets and competencies, and offering training and development programs to develop and enhance employee capabilities.
  • Organizational Structure:Establishes the hierarchical structure, reporting lines and roles of the organization. It also formalizes job descriptions, roles, and responsibilities: this allows for coordination and collaboration.
  • Talent Acquisition and Management:Talent development refers to building skills, knowledge, and capabilities among employees through training, coaching, mentoring, developmental assignments, and different career development opportunities. This component safeguards employee growth and engagement while rationalizing their competencies along organizational needs (Noe et al., 2019).
  • Leadership Development:Focuses on identifying and developing leadership strengths internally, through leadership development programs, mentoring, succession planning and any other mechanisms to ensure the development of a strong pipeline for leadership.

Enterprise Architecture Frameworks for Business Process Redesign

• Process Alignment: COBIT offers a standardized collection of processes and control objectives, which could serve as a baseline for determining how business processes are mapped to IT activities. For example, an organization’s current processes could be mapped to COBIT’s process coverage matrix to identify deficiencies, redundancies, and inefficiencies. Furthermore, the COBIT processes and related control objectives could be used during process redesign to make sure that processes are aligned with best practice.
• Governance and Control: COBIT stresses effective governance and control of the IT function and provides a governance framework, which includes management guidelines, control objectives and performance indicators, that can assist organizations to identify clearly who is accountable for what, who makes decisions regarding people, processes and technology, and how these decisions are implemented through effective controls to achieve efficient operations.
• Risk Management: BPR and EAD initiatives mandate process, system, and technology architecture changes. COBIT can help organizations identify, assess, and monitor these risks. Reviewing COBIT risk management practices, and implementing these controls where needed, helps mitigate new risks that could arise due to redesign.
• Performance Measurement: Since COBIT promotes the development of performance indicators to gauge the adequacy of IT processes, the framework allows an organization from a process perspective to define performance metrics for enhancements in BPR and EAD, followed by implementation of a performance measurement framework to measure initiatives taken to meet the overall business strategy and business process goals. This approach enables them to monitor critical processes, diagnose issues, track performance, provide meaningful feedback to synergize actions, effect improvements and enhance efficiency.
• Compliance and Standards: COBIT utilizes industry standards and regulatory obligations such as ISO 27001, COSO and ITIL. Through its integration with these standards, organizations can promote adherence to the required regulations and industry best practices in BPR and EAD initiatives. Doing so can instill a level of assurance and security within IT systems.
• Continuous Improvement: COBIT promotes a feedback loop for the Plan-Do-Check-Act (PDCA) cycle, effectively encouraging a state of continuous improvement to IT governance and management. Through the PDCA approach, organizations are ‘always on’ and continuously monitor, measure, evaluate and adjust their BPR and EAD efforts. COBIT’s feedback engineering, where the Design step (analyze current processes, identify, and design future processes) is repeated after Do (deploy and measure), provides for refinement of the PDCA cycle.

LEAN Framework

• Waste Reduction: Lean thinking aims to reduce so-called ‘eight kinds of waste’ (known as the ‘8 Wastes’): overproduction; waiting; unnecessary transportation; excess inventory; motion; over-processing; ‘defects’ (by which is meant product waste, such as rejects, reworks, etc.); and unused employee creativity. To identify areas for improvement, organizations currently following a specific process map out all their steps and then apply Lean principles: because of this mapping, they can identify which tasks in the process are wasteful, and the process can be modified and refined to reduce or remove waste.
• Value Stream Mapping: A key Lean technique involves the use of value stream mapping to visualize and analyze flows of materials, information and other process activities in order to identify and eliminate ‘muda’ (waste), or the progress of goods through a process that does not directly contribute to the creation of value from the customer perspective.
• Standardized Work: ‘Lean’ stresses the importance of standardized work. Essentially, this encourages consistent approaches to performing work tasks, namely those processes variations likely to introduce error. By documenting and implementing standardized workflows, organizations can create much-needed design leverage – the ability to scale up changes in design – through architectural design that is capable of redesign, and the continuous improvement of practice.
• Continuous Improvement: Lean emphasizes a ‘constant improvement’ (kaizen) mindset. Empowering staff at all levels to surface opportunities for kaizen leads to ever-improving work processes, a business philosophy that extends to improving business processes and the architecture to support them.
• Customer Focus: Lean stresses responding to customer needs. By using techniques like customer value analysis, it is possible to distil the value chain to the truly relevant, genuinely appreciated parts. This helps to direct the process of evaluating redesign efforts, setting priorities, and aligning architectural choices in support of basic customer requirements.
• Just-in-Time (JIT): This is a Lean concept. Just-in-Time refers to the practice of producing or delivering goods or services exactly when they are required and is another key principle of Lean. If you are using JIT, you consistently time all inputs and outputs at the instant when they are needed by the next process to minimize inventory and lead times, so as to maximize value and minimize non-value-adding activities such as redundant storage.
• Cross-Functional Collaboration: Lean promotes collaborative working across functional areas. Cross-functional collaboration enables better stakeholder involvement during business process redesign and enterprise architectural design, for those involved can bring expertise from different areas (both within and outside the IT department), share knowledge, and design better and more efficient processes and systems.

Case Study: Multinational Corporation's Struggles with TOGAF

• Wider Perspective: IAF adds enterprise vision and process perspectives to those of the Zachman Framework – Governance, Policy, Strategy, Motivation, besides the classic Zachman Framework’s six perspectives of What, How, Where, Who, When and Why. This sets up a wider aperture for developing an enterprise view or understanding, not only of what the enterprise does and how it does it, but also why it does what it does, at what time, and for whom, which can help determine the current and future direction of the enterprise.
• Alignment with Organizational Goals: IAF truly emphasizes alignment of Enterprise Architecture with business objectives. It encourages deriving business goals, strategies, and policies to be the driver for design and optimization of business processes. With strategic goals set in IAF, organizations can constantly align their business process redesign objectives with their higher business goals.
• Layered Approach: IAF provides a layered approach to enterprise architecture, which allows organizations to represent the enterprise in a hierarchical and structured fashion. A layered approach can decompose complex processes into smaller units to be studied and modified in a stepwise process. This layered approach is essential for analyzing dependencies between layers, such as optimizing the process between the business, application, and technology layers of enterprises.
• Traceability and Impact Analysis: Traceability between architectural elements and business processes, and between different architectural elements, is a key concern for IAF, to understand how a change to one part of a system would affect other parts of it. These traces are associated to business processes, applications, data, and infrastructure components. For example, when mapping out detailed business processes, the interested stakeholders will analyze which applications, data and components within the infrastructure are part of the processes.
• Governance and Control: IAF provides idealized approaches for the establishment of governing and controlling structures of the Enterprise Architecture practice. In other words, IAF provides guidelines for the establishment of processes, rules, roles and responsibilities, and review mechanism to ensure proper decision making, use of right use mechanisms or IT applications, and provision of feedback to the decision makers. Governance requirements are more crucial in the context of business processes redesign because they guide who can, how and from where the enterprise processes can be designed in conformity with the architecture principles, standards and guidelines contained in IAF.
• Iterative and Phased Approach: Like the Zachman Framework, but again using a different name, IAF denotes an iterative and phased approach to the development of Enterprise Architecture. This simply means that organizations can progressively develop models of their business operations, such as application designs to support business processes. This approach enables organizations to assess and determine how to change those business processes to conform with the overall enterprise architectural design and apply the changes in a controlled and manageable manner.
