At The Open Group, we have a proud record of creating and maintaining Standards, Frameworks, Reference Architectures, Tools, Models, and Guides that have proven to be invaluable to the Enterprise Architects community, whether they are industry-wide or aligned to specific vertical sectors.

What they all have in common though is that they have been created by leading experts in their associated field, based on industry best practices adopting a thought leadership approach, ensuring they meet the exacting needs of their audience.

Architect Toolkit

While all standards of The Open Group are designed so they can be adopted independently of one another, the greatest value for an organization can be derived when they are used in unison — the sum of the parts should be greater than the whole.

In the Architect's Toolkit, we have collated a portfolio of the most pertinent ones for Architects together in one place.

Additionally, for most of these tools, there is certification available so practitioners can evidence they have the skills required, and recruiters can take the guess work out of the recruitment process — all backed up by our open badges program.


To illustrate the synergy between standards, here we see the value the TOGAF® and Open Agile Architecture™ Standards bring together, providing an improved overall outcome when used to drive Digital Transformation.

The TOGAF Standard is an Enterprise Architecture framework that delivers efficient and effective Enterprise Architecture to support organizational transformation for different use-cases and architecture styles, and Open Agile Architecture provides guidance on how an organization should address Digital and Business Transformation in an Agile manner.

TOGAF Standard

The TOGAF® Standard

The TOGAF Standard, a standard of The Open Group, is a proven Enterprise Architecture methodology and framework used by the world’s leading organizations to improve business efficiency, and enable Digital Transformation.

It is the most prominent and reliable Enterprise Architecture standard, ensuring consistent standards, methods, and communication among Enterprise Architecture professionals. Those professionals who are fluent in the TOGAF approach enjoy greater industry credibility, job effectiveness, and career opportunities. This approach helps practitioners avoid being locked into proprietary methods, utilize resources more efficiently and effectively, and realize a greater return on investment.

The Open FAIR methodology is ideal when an Architect needs to quantify and mitigate risk. It is an open and independent information risk analysis methodology based on Open Factor Analysis of Information Risk (FAIR).

The Open FAIR Body of Knowledge consists of two standards:

  • Open Risk Taxonomy Technical Standard (O-RT)
    • This defines a standard taxonomy of terms, definitions, and relationships used in risk analysis
  • Open Risk Analysis Technical Standard (O-RA)
    • This describes process aspects associated with performing effective risk analysis

In addition, the Security Forum has also developed the Open FAIR™ Risk Analysis Tool to help perform quantitative Open FAIR risk analysis as defined in The Open Group Risk Analysis (O-RA) and Risk Taxonomy (O-RT) standards.

For the purpose of convenience, efficiency, and security, dependence on software systems in our daily life has grown exponentially. Most computer systems are used for long periods of time, and are being constantly improved in service objectives and users’ requirements. As technologies evolve and regulations change, this results in ever-increasing complexity. As complexity has increased, dependability of these software systems cannot be achieved solely by using conventional technologies. 

To achieve dependability in such large and complex systems, O-DA introduces the notion of Assuredness, providing confidence that ensures implementation of an architecture has met the requirements specified to be assured.

The Open Data Element Framework, known as the O-DEF Standard, enables basic units of data to be classified, so that equivalences and similarities between them can be easily determined. This simplifies the development of interface software and contributes to improved management and organization of data. The O-DEF Standard facilitates interoperability through the use of a common data vocabulary.

The O-DEF Standard consists of an index and a method for using it to classify data elements. Following this method, a practitioner can tag a data element by assigning a name and numeric identifier to it according to its meaning. The index is federated; comprising a core index and a collection of plugins.
