What is the Zachman Framework Used For?
In today's IT-driven business world, the need to align IT with the business and business strategy becomes ever more important.
Having a framework that offers a structured approach to facilitate this alignment, whilst ensuring consistency, reducing complexity, and improving communication among stakeholders is essential.
The following article introduces one such methodology, the Zachman Framework.
This guide describes the Framework, what it is used for, the benefits and challenges of its adoption, the best way to apply it to the organization and how it can be best used with Ardoq.
What Is the Zachman Framework?
The Zachman Framework is for Enterprise Architecture (EA). Developed by John Zachman in 1987,it provides a formal and structured way of defining and analyzing an organization's information infrastructure.
It aims to organize and classify an organization’s perspectives and models, thereby ensuring interoperability, business, and IT alignment and enabling detailed analysis and design of an enterprise system.
Zachman Framework Template: Structure Explained
The Zachman Framework structure consists of a 6x6 matrix that organizes and categorizes Enterprise Architecture based on different perspectives (rows) and aspects (columns).
If properly completed, this defined matrix structure ensures that all aspects of an enterprise's architecture are included.
Rows (Perspectives)
The rows represent different perspectives that correspond to a specific stakeholder's viewpoint. Each perspective answers the question of "Who is looking at it?" They range from high-level strategic views to detailed implementation views.
-
Scope (Planner's View) provides a high-level view of the enterprise from an external perspective, defining the overall context and objectives.
-
Business Model (Owner's View) focuses on the business concepts, processes, organizational structure, and how the business operates.
-
System Model (Designer’s View) details the information systems architecture, defining data models and system functionality.
-
Technology Model (Builder’s View) concentrates on the technology infrastructure and implementation necessary to support the information systems.
-
Detailed Representations (Sub-contractor’s View) shows the detailed specifications for components and configurations necessary for construction and deployment.
-
Functioning Enterprise (User’s View) is the actual operation of the systems and processes within the enterprise. It focuses on how the system is used.
Columns (Aspects)
The columns represent different aspects or interrogatives concerning the Enterprise Architecture. These columns answer "What aspect are we considering?" and are designed to explore each perspective fully:
-
What (Data/Catalogs) information or data, such as data models, entities, and relationships, is needed and used in the enterprise.
-
How (Function/Processes) processes and functions perform, including business processes, workflows, and transformations.
-
Where (Network/Locations) includes the spatial distribution of the enterprise's operations such as physical locations, networks, and connectivity.
-
Who (People/Actors) covers the people and organizations involved together with their roles, responsibilities, and organizational units.
-
When (Time/Events) relates to the temporal aspects and timing of operations such as schedules, events, and time-based conditions.
-
Why (Motivation/Goals) are the motivation, rationale, and goals, including business goals, objectives, and motivations that drive business outcomes.
Matrix
Each cell in the 6x6 matrix corresponds to the intersection of a specific perspective and aspect, creating an environment for analyzing and organizing Enterprise Architecture. An example of what this might look like is as follows:
| Aspect/ Perspective |
Scope | Business Model | System Model | Technology Model | Detailed Representations | Functioning Enterprise |
| What (Data) | Objectives/Lists | Business Entities | Logical Data Models | Physical Data Models | Data Definitions/ Schemas |
Data Transactions/ Records |
| How (Function) | Business Processes | Activities/ Workflows |
Application Architecture | System Architectures | Programs/ Configurations |
Functioning Processes |
| Where (Network) | Locations/ Facilities |
Business Locations | Distributed Systems | Network Configurations | Locations of Components | Operational Sites |
| Who (People) | Organizational Units | Actors/Roles | User Interfaces/ Access | Identity Management | Security and Access Control | Active Users/Operators |
| When (Time) | Events/ Cycles |
Business Events | Processing Structures/ Timing | Scheduling/ Timing Specs |
Timing Definitions | Actual/Event Logs |
| Why (Motivation) | Business Goals/ Objectives |
Business Rules/Policies | Rule Models | Implementation Strategies | Detailed Rules | Performance Metrics |
Rules
The Zachman Framework defines seven rules to ensure consistency and robustness in Enterprise Architecture:
Rule 1: The columns have no order, as each represents a distinct, descriptive focus on an aspect of the enterprise that stands independently from the others.
Rule 2: Each column has a basic mode that embodies the fundamental question it addresses (What, How, Where, Who, When, and Why).
Rule 3: The basic model of each column must be unique to avoid redundancy and should be distinguishable from one another, ensuring each aspect stays focused on its specific question.
Rule 4: Each row represents a distinct perspective from which stakeholders view and understand the enterprise, each adding depth and context.
Rule 5: Each cell is unique in its content and focus; therefore, the intersection of each column and row (each cell) provides a distinct piece of the overall Enterprise Architecture puzzle.
Rule 6: The composite or integration of all cell models in one row constitutes a complete model from the perspective of that row.
Rule 7: The logic is recursive so that the framework can be applied repeatedly at different levels of granularity, allowing for detailed refinement and development of Enterprise Architecture over time.
These rules promote a structured, thorough approach to Enterprise Architecture.
What Is the Zachman Framework Used For?
Its primary use cases include strategic planning and alignment to ensure that IT initiatives are directly aligned with business objectives. It facilitates informed decision-making by providing a clear structure for understanding relationships between various enterprise components.
The Framework offers a holistic view of the enterprise by categorizing all architectural elements, ensuring no aspect is overlooked. To enable such a view, it provides a standardized approach for documenting every facet of EA, improving clarity and aiding communication.
The Zachman Framework helps with the scope definition of any architectural project by breaking down complex systems into manageable components. This activity promotes system interoperability and integration, reducing silos and fragmentation.
The Zachman Framework helps with two critical areas: change management/adaptability and regulatory compliance/risk management.
Change management is supported by enabling a thorough analysis of how changes in one area impact others. As such, it helps an Enterprise Architect adapt to evolving business needs and technological advancements.
Compliance is achieved by ensuring that organizational processes and systems meet industry standards and regulatory requirements. The framework is also used to identify potential risks and dependencies, aiding in effective risk management strategies.
Finally, the Zachman Framework helps an organization address different stakeholder concerns by categorizing information into perspectives (planner, owner, designer, builder, subcontractor, user). This facilitates communication and understanding among various stakeholders through a common language and framework.
Zachman Framework vs Traditional Software Methodologies
The Zachman Framework and traditional software methodologies serve different, albeit complementary, purposes within organizational and software engineering.
There are several differences between the two approaches, and it is important to understand them when choosing the correct framework for an organization.
The primary purpose of the Zachman Framework is to focus on EA, providing a structured methodology to organize and analyze an organization’s information, systems, and business processes. Traditional software methodologies focus on systematically developing, deploying, and maintaining software applications.
The scope of Zachman is, therefore, broad, encompassing all aspects of EA, including business processes, data management, IT infrastructure, and organizational alignment. The scope of traditional methodologies is narrower and concentrates on the software development lifecycle, starting with requirements gathering and going through to design, coding, testing, and maintenance.
As explained, the Zachman Framework utilizes a 6x6 matrix to address different perspectives and aspects of an enterprise and provides a classification scheme rather than a step-by-step process. It is, therefore, more about organizing information and enabling comprehensive analysis.
Traditional software approaches are typically linear or iterative, with defined phases such as requirements, design, implementation, testing, and maintenance. They provide specific, actionable steps and procedures to follow during the software development lifecycle.
The Zachman Framework provides a holistic view of Enterprise Architecture, including strategic, organizational, and technical facets. It covers the "what," "how," "where," "who," "when," and "why" of an organization’s structure and processes.
Traditional methodologies are specific to software production, focusing on delivering functional software. They emphasize requirements specification, system design, coding, testing, and deployment activities.
The Zachman Framework is extremely flexible and can adapt to various organizational needs and changes. It can accommodate different methodologies and approaches within its structure, providing an evolving high-level classification scheme.
The flexibility of traditional software methodologies varies significantly depending on the approach. Agile approaches are designed to adapt to changing requirements, whereas others, like Waterfall, follow a more rigid sequential approach.
The Zachman Framework caters to various stakeholders, including business executives, architects, designers, and operational staff. It provides multiple viewpoints, addressing all stakeholder concerns (from high-level strategic to detailed and technical).
Traditional software processes usually focus on the needs of developers, testers, project managers, and end-users. They concentrate on delivering specific software functionality and meeting user requirements.
The Zachman Framework is usually employed in large-scale enterprises. It serves as a guiding Enterprise Architecture framework to ensure that all necessary components and relationships are considered.
Traditional approaches are only used within software development projects and provide a structured way to manage the software development process.
