Dynamic Enterprise Architecture is an enterprise architecture framework developed by the consulting company Sogeti. In , the vocabulary and generic patterns were being published in an online repository under an independent URL, but on under a subdomain of the Sogeti Netherlands website. There was a LinkedIn group created. Development of the method continued at Sogeti until mid ; the Repository is being continued under the name Open Infrastructure Architecture method. DYA Infrastructure is a method, it brings business agility, architectural effectiveness and manageable and expandable infrastructure landscapes within the grasp of any organization. DYA infrastructure provides three mutually supportive elements: A definitive description of infrastructure architecture as an integral part of the architectural process, how it helps enforce architectural principles—with two focal points: defining a functional approach to infrastructure facilities and how to select and work with the appropriate quality attributes The building blocks model that

Business, information and infrastructure architecture have a common goal, namely to optimally support the operational management of an organization. This is not possible without input from and feedback between the three architectural disciplines. In order to act efficiently and decisively at the same time within the architecture process, the disciplines must start from the dynamics and structures that underlie their own areas of competence.
This certainly also applies to infrastructure architecture, which must make its own role known and manageable by creating clarity about the concepts that apply in this field. This is easiest by describing the infrastructure solutions in logical and functional terms. DYA Infrastructure uses a set of ' Quality attributes 'to describe the' quality 'of solutions. The Quality attributes take an important role in the mutual coordination between architectural disciplines in the architectural process, because regardless of the underlying technological structure, the quality attributes can be embedded in each of the architecture domains, and then be used in every aspect of the final solution.
At the same time, the Quality attributes also provide input for design, realization and testing of solutions within the own infrastructure field. In this way the Quality attributes run as a red thread through the different phases and activities involved in the business of infrastructure architecture. That is why Quality Attributes are a recurring theme in the different phases and activities of the infrastructure architecture. That is why it is of the utmost importance to carefully select and fill in the Quality attributes.
At the very least, they should be able to reflect the unique and inherent qualities of the infrastructure solution. Cooperation between architecture disciplines requires mutual understanding and agreement on the quality attributes used.
In the architectural process, the architecture disciplines have to adapt themselves where necessary, but without denying themselves. The participating disciplines can be expected to make clear what they have to bring in and where their own - or not intrinsic - boundaries lie.
Not all requirements and wishes can always be fulfilled effectively, especially when they are partially contradictory. If partial architectures are to be able to act effectively, they need direction from the architectural process as a whole, but this direction must also fit in with the nature of their own fields. In the architecture process, it should be clear on which Quality attributes the accent is laid, so that it becomes clear which solution directions are realistic and appropriate.
With the mandate obtained from cooperation and coordination, solutions can be developed within each discipline that are not isolated, but are consistent and appropriate for the whole of the architecture. This mandate also provides guidance in the monitoring and reporting of completed results.
In order to prevent disciplines from talking past each other, clarity and agreement must exist about the concepts that the disciplines bring into the architecture process and along which the coordination is conducted.
Infrastructure architecture incorporates its own Quality attributes into this alignment and explains this in addition to the Quality attributes of business and information architecture. In addition to the Quality attributes, two factors are involved that influence the possible solutions, namely costs and time.
These factors are imposed from the outside usually by the organization and affect all forms of architecture. In general, time and money are the most important frameworks that determine the size and quality and thus the feasibility of a solution.
In many cases, time and money are so restrictive that a different weight must be given to Quality attributes to allow for a realistic solution. With this, the architectural process will rightfully also be a debate, where exchanging and weighing arguments must lead to a solution that optimally serves the interests of an organization within the limits set by money and time. Quality attributes are somewhat abstract in nature, because they indicate the 'how' and not the 'what'.
In the architecture process, links between correlating quality attributes from the various disciplines are sought and indicated. This makes it easier to see what influence choices within one discipline have on solutions and possibilities within other disciplines. The more this happens proactively, and the more Quality attributes can be linked, the more constructive the process will be.
Within the alignment, some Quality attributes between disciplines can easily be traced to each other, while others emphasize the individuality of one of the disciplines. However, the different disciplines will usually recognize themselves in the Quality attributes of the other disciplines - if the Quality attributes are well defined and explained.
Particularly from the objective that infrastructure must function as a utility, three categories, each with two Quality attributes, are distinguished with which the intrinsic quality of infrastructure solutions is expressed:. The six Quality attributes defined here do not apply exclusively to infrastructure applications, but within the 'infrastructure as utility' objective, they are the most leading.
Not all partners are always sufficiently aware of the meaning of quality attributes that apply to their own field and the consequences of statements about them.
However, they too will indicate which wishes and requirements they have with regard to a particular solution.
It is then up to the other participants in the architecture process to clarify the consequences of this for their own discipline to the other disciplines. Infrastructure architecture indicates that this requirement could be achieved in terms of availability, but that this has considerable consequences with regard to the term scalability and the money factor. A judgment is then expected from business architecture whether the postulated availability requirement is sustainable in that light.
It must be prevented that disciplines impose on each other quality attributes and conceptual frameworks, because this frustrates the process and ultimately works counterproductive, because these conceptual frameworks outside the own domain are meaningless.

DYA Infrastructure Architectural process
Dynamic Enterprise Architecture DYA is an enterprise architecture framework developed by the consulting company Sogeti. The DYA framework is built up with the following modules: . In , the vocabulary and generic patterns were being published in an online repository, initially under an independent URL, but later on under a subdomain of the Sogeti Netherlands website. Development of the method continued at Sogeti until mid ; after that, development was continued under the sponsorship of BiZZdesign , at which time the name of the method was changed to Open Infrastructure Architecture method OIAm.
