Zachman Framework In A Nutshell

The Zachman Framework is the brainchild of business and IT consultant John Zachman.  The Zachman Framework is a core component of enterprise architecture. It is a formal and structured means of viewing and defining an enterprise. 

Aspect	Description
Definition	The Zachman Framework is an enterprise architecture framework used to structure and organize the essential components of an organization’s information technology (IT) infrastructure, processes, and data. It provides a comprehensive view of an enterprise and its complex systems.
Origin	Developed by John Zachman in the 1980s, it draws inspiration from architectural and engineering practices. Zachman introduced a structured approach to understand and document the various aspects of an enterprise’s architecture.
Structure	The framework comprises a 6×6 matrix that categorizes architectural aspects into six rows representing different perspectives (Who, What, Where, When, Why, How) and six columns representing different stakeholders (Planner, Owner, Designer, Builder, Subcontractor, Worker).
Perspectives	– Who (Scope Level): Concerned with the stakeholders, actors, and roles within the organization. – What (Business Level): Focuses on business processes, data, and information. – Where (Location Level): Deals with physical locations and distribution of resources. – When (Time Level): Addresses timing and schedules. – Why (Motivation Level): Explores the reasons and motivations for actions and decisions. – How (Technological Level): Concentrates on the implementation and technology aspects.
Stakeholders	– Planner: Concerned with strategic planning and long-term vision. – Owner: Represents business leadership and accountability. – Designer: Focuses on creating solutions and architectures. – Builder: Responsible for constructing and implementing the solutions. – Subcontractor: Collaborates on specific tasks or components. – Worker: Executes day-to-day operations and tasks.
Purpose	The Zachman Framework aids organizations in developing a holistic understanding of their enterprise, aligning IT strategies with business goals, facilitating communication between stakeholders, and improving decision-making related to IT investments and architectural changes.
Application	Enterprises across various industries use the Zachman Framework to support enterprise architecture initiatives, strategic planning, business process improvement, IT governance, and ensuring IT projects align with the organization’s overall strategy.
Benefits	– Provides a structured and standardized approach to enterprise architecture. – Enhances communication and collaboration among stakeholders. – Facilitates IT governance and aligns IT with business objectives. – Improves decision-making regarding IT investments and changes. – Supports the management of complex IT systems and their evolution over time.
Challenges	– Initial complexity and the need for training to effectively implement the framework. – Maintenance and keeping the framework up-to-date as the organization evolves. – Ensuring all stakeholders actively participate and contribute to the framework.
Notable Users	The Zachman Framework is used by organizations in various sectors, including government, finance, healthcare, manufacturing, and technology, to manage their enterprise architectures effectively. Notable users include IBM, Boeing, and the U.S. Department of Defense.

Understanding the Zachman Framework

Zachman created the framework in response to the difficulty that many large and complex businesses have in managing change. Indeed, many do not understand their own organizational structure. Many others do have this knowledge, but the information is confined to individual employees or departments and is not freely available.

The Zachman framework is a means of classifying organizational architecture. It considers the pre-existing functions, elements, and processes of a business so that decision-makers can proactively manage change.

Importantly, the framework is an enterprise ontology that shows an organization and its information systems from different perspectives. It is not a methodology that can be followed to produce a desired result.

The structure of the Zachman Framework

The Zachman Framework is a two-dimensional classification scheme in the form of a 36-cell matrix, with each cell focusing on one perspective or dimension of the enterprise.

Columns in the matrix represent interrogatives, or questions that are asked of the enterprise:

1. What (data) – what data or information is required to institute change or carry out a project?
2. How (function) – how does the business work? What are its processes?
3. Where (network) – where does the business operate?
4. Who (people) – who runs the business? What are the business units and how are they structured?
5. When (time) – when does the business perform its processes? What are the schedules and workflows?
6. Why (motivation) – what motivates the business to choose one solution over another? How was the solution arrived at?

Rows in the matrix represent the perspectives of key stakeholders who are involved with change and are ordered according to priority. 

Combining all six cells in one row gives a holistic representation of that enterprise according to one (or each) of the following perspectives:

1. Planner’s view (Scope contexts) – or the purpose and strategy of the business that defines the arena for the other views.
2. Owner’s view (Business concepts) – the structure, functions, and organization of the business. This gives insight into areas that might be automated.
3. Designer’s view (System logic) – how will the system satisfy the informational needs of the business? Ignore solution specific aspects or production constraints.
4. Implementer’s view (Technology physics) – or how the system will be implemented. What role will technology play in creating solutions or alleviating production constraints?
5. Sub-constructor’s view (Component assembles) – what are the specific details that need to be clarified before production can begin? Since this view is more concerned with a part of a system and not the whole, it is sometimes considered less important.
6. User’s view (Operations classes) – or the view of a functioning system within its respective operational environment.
