The Open Group
The Open Group is a global consortium responsible for developing the TOGAF® (The Open Group Architecture Framework) standard, certification, and a range of free guides for enterprise architecture.
The Open Group Library contains a range of standards, guides, whitepapers and other useful publications.
The following guides are a sample of the guides and white papers available as free PDF downloads once you have created an account for The Open Group website.
If you are a first time user you need to register for an account.
Some content in the Open Group Library, such as the TOGAF standard, is only available to The Open Group Members.
Using the TOGAF® Framework to Define and Govern Service-Oriented Architectures
Guidance on how the architect can use the TOGAF 9.1 standard to develop, manage, and govern Service-Oriented Architecture (SOA) or any architecture where SOA is part of the scope. This should facilitate the common understanding of the process for the development of SOAs and greatly improve alignment between the business and information technology communities.
The TOGAF® Technical Reference Model (TRM)
This guide describes the TOGAF Technical Reference Model (TRM), including the core taxonomy, graphical representation, and the detailed platform taxonomy.
This guide describes the Business Scenarios method, which is a technique to validate, elaborate, and/or change the premise behind an architecture effort by understanding and documenting the key elements of a Business Scenario in successive iterations.
This guide addresses how to identify, define, model, and map a value stream to other key components of an enterprise’s Business Architecture.
The TOGAF Integrated Information Infrastructure Reference Model (III-RM): An Architected Approach to Boundaryless Information Flow™
This guide addresses the TOGAF Integrated Information Infrastructure Reference Model (III-RM) in terms of its concepts, an overview, and its detailed taxonomy.
The TOGAF® Leader’s Guide to Establishing and Evolving an EA Capability
This guide puts forward advice on establishing an Enterprise Architecture (EA) Capability that aligns to a set of requirements and expectations specific to each enterprise. It proposes an approach for the standing-up and enhancing of an enterprise’s EA Capability based upon the established best practice contained within TOGAF®, an Open Group standard.
A Practitioners’ Approach to Developing Enterprise Architecture Following the TOGAF® ADM
This guide puts forward an approach to develop, maintain, and use an Enterprise Architecture that aligns to a set of requirements and expectations of the stakeholders and enables predictable value creation.
Architecture Project Management
This guide provides Architecture Project Teams with an overall view and detailed guidance on what processes, tools, and techniques of PRINCE2® or PMBOK® can be applied alongside the TOGAF ADM for project planning, monitoring, and control. Further, a detailed mapping of the processes and deliverables of the TOGAF framework against PRINCE2 and PMBOK is provided to visualize how those concepts come together.
As the discipline and practice of Business Architecture has continued to grow and mature, the concept of the “business capability” has emerged to become a fundamental component in the development of a Business Architecture. This Guide looks to answer some important questions about what a business capability is and how it is being used to enhance business analysis and planning.
This guide provides a basis for Enterprise Architects to understand and utilize business models, which describe the rationale of how an organization creates, delivers, and captures value. Business models provide a powerful construct to help focus and align an organization around its strategic vision and execution. In this Guide we cover different forms of business models and approaches to modeling, from the conceptual down to a practical example.
A Practical Approach to Application Portfolio Consolidation using the TOGAF® Standard
This guide is intended to help enterprises who are attempting to simplify, rationalize, and consolidate their application portfolios in support of delivering business value and enabling business agility. It shows how enterprises can use the TOGAF® standard to identify and deliver opportunities to simplify their application landscape, and to help in the transition from legacy to cloud.
Starting an Enterprise Architecture Capability in the Government Sector
This guide is written for the non-defense public sector. Its focus is to help leaders build a team and create, deliver, and use architectures within the public sector, recognizing the differences between public and private enterprises.
Agile Architecture in the Digital Age
The effectiveness of agile processes is too often jeopardized because the architecture and organizational pre-requisites of agility are neglected. This White Paper proposes a new architecture framework, the Agile Architecture Framework (AAF), that meets the needs of the digital enterprise.
The Seven Levers of Digital Transformation
This White Paper presents the reader with key considerations, the seven levers that influence successful outcomes from the Digital Transformation journey. Once the impact of the seven levers is understood, a well-governed and innovative path can be defined to reach a positive outcome at each stage of change.
Capability-Based Planning: The Link Between Strategy and Enterprise Architecture
This White Paper describes how a Capability-Based Planning (CBP) method is a solution for the alignment between business strategy and Enterprise Architecture. It includes a detailed example using ArchiMate 3.0 notation.
