I believe that the system architecture discipline has not Systems today are characterized by a large number of kept pace with changes in technology and business over unknowns and uncertainties, a lack of control over many the past 25 years. Technology is more complex. Systems change and tight relationships between business and are more complex. There are whole classes of new business solve.

There is more uncertainty, there are more complex problems that the framework approach cannot cope with. Business today Underpinning the POSA is the concept of an architect The environments in which organizations operate today are being the bridge between a business problem and its solution. It is unlikely integrated into a larger context. Communications external that the architect will know enough or have authority to the enterprise are the norm. Most, if not all, large unilaterally to make decisions in either domain.

As such, businesses cannot exist without their information systems. The key role business and business processes. They are enabling different of a POSA architect is to operate in multiple domains, business models, changing the way existing businesses acting as a domain translator between the businesses problem operate, and introducing new types of business.

Many and the solution, and facilitator for problem solving. The businesses have extensive presence on the Internet, and architect also needs to look outside the problem-solution many businesses exist only in virtual space. The publishing industry provides a rich set of examples of change. Physical book The problem-oriented system architecture approach sellers have been affected by new technologies. site now POSA learns and borrows from cybernetics and control sells books online.

It has no customer-facing facility, only theory, disciplines that facilitate the understanding and 10 : 4 B. It must be possible been done recently by Terry Hill of NASA to apply control for the problem to be analyzed and understood and for theory to project management [15].

In addition, when implemented, development. Decomposition of the solution beyond the scope of this article.

This paper concentrates on development should be possible without the risk of the use of proper partitioning, feedback, predictive control introducing unknown, critical, or unmanageable systems, and optimization of outcome against potentially dependencies.

POSA treats architecture and system development as a dynamic process that has as its Complex problemsVThe characteristics of a complex desired outcome a solution to a problem that, when solved, problem are that the problem is well understood, but the is of value to the business.

The solution may be implemented solution is unclear or uncertain. The iterations either stop or become less frequent when an Although it is clear what the solution to a complex optimal solution has been selected and moves into problem must do and the criteria against which it is to be implementation. The iterations move through addition, there may be requirements of the solution to a various phases, recognizing that the basis on which previous complex problem that are not derivable from analysis of decisions were made may change.

At some point it might the problem but that arise because of the solution itself. At another point, the assumption that the problem requires particular application functionality. In order to reduce risk, however, it is necessary to environment that supports nonfunctional requirements such check that these assumptions are valid.

The architect needs to as availability and performance. The environment required control the POSA process, the system cannot control itself.

Other examples include when approach to solving a business problem. This requires the solution needs to be integrated into an existing understanding the nature of, and relationship between, the environment, when new technology is being utilized, and business goal, the business problem, and potential solutions. The solution to a tame problem does not problem are that the problem is unclear, the solution is IBM J.

Understanding a complex or wicked problem cannot be The term Bwicked[ problem was originally coined done by looking at its constituent parts. The consequences by Horst Rittel [17] in the context of a general theory of of inter-relationships and emergent behaviors are only visible planning and was applied to problems that had a high when viewing the problem as a whole.

Selecting the best way to approach the mechanism without destroying the relationship between problem becomes a problem itself. In addition, what compounds the but unless the solution is recombined and its behavior situation is that when a particular solution is considered or measured as a whole, there is no guarantee that the total implemented, the problem itself can change.

There are usually many consequences to implementing a A system architecture is a set of partitioned models.

Why Zachman Framework?

Managing these consequences can lead to new Control theory would suggest that the approach to wicked problems. Unlike the framework approach, implementation. This is because the modeling approach can and nature of the problem. Incompetent or inexperienced practitioners can and comparisons. Every problem should be considered, at least initially, Feedback as unique.

This is a technique that compares the input to a be differences. The circumstances and context could be process with the output of that process. Corrective action different, and the team delivering the architecture and system is taken if there is a discrepancy. This is a very powerful development is unlikely to be exactly the same; even if controlling technique and is used in many control systems. By treating strategy, architecture, and development activities as a dynamic process and applying feedback techniques Applying principles of cybernetics and to that process, there is an increased likelihood that an control theory optimal outcome will be achieved.

In order to establish an effective feedback loop, there are Partitioning a number of issues that need to be addressed. In order to A major feature of cybernetics and control theory is modeling properly connect the problem space with the architecture to understand problems and to develop solution options.

The primary the solution.

In fact any architecture or design artifact is best reason being that, in the POSA, the problem is considered considered to be a prediction or estimate. What actually matters is the goal that Unfortunately, a predicted solution cannot be directly the business is trying to achieve and the value derived compared with a problem. The problem and its solution are from the problem being solved. The problem is dependent on different things.

It is necessary, therefore, to translate from the business goal. Bringing the problem into the feedback the solution domain back into the problem domain. Part loop has a number of effects. First, the business goals of this translation back into the problem domain should associated with the problem are subject to analysis and include a recombination of the components that have been scrutiny. In other words, the problem itself is questioned introduced because of partitioning into a complete system.

This are a major role of the architect. All these concepts are means that external disturbances, consequential problems, integrated into the POSA, which is shown in Figure 1. If the predicted solution Case studies does not solve the problem and solving the problem does In , Sir Peter Gershon conducted a review of Australian not meet the goals, some form of corrective action will Government Information and Communication Technology be taken.

ICT [18]. The difference 15 years could be avoided. Subsequently, AGIMO initiated between a complex and a wicked problem lies in certainties a project to develop a data center strategy.

I joined the and relationships in the problem space. The feedback project team in July as lead IT architect loop around a wicked problem needs to have strong links and strategist. This statement became the problem to be addressed by Initially, it generates solutions options; the feedback the strategy. The feedback problem.

There were multiple stakeholders who were likely process continues to operate, concentrating on ensuring to exhibit unpredictable behaviors. Most of the government that subsequent decision making continues to lead to a agency stakeholders had different objectives and concerns solution that solves the problem.

What is Zachman Framework?

Knowing whether a particular solution would solve the problem was also Comparisons uncertain. Measurement hosted. This strategy phase addressed the structure and can take one of two forms, counting or comparison. In the relationships of the complete set of data centers.

Subsequent context of system architecture, what needs to be measured phases addressed issues of the systems within data centers.

In a project that is based upon the framework to the strategy development. After an initial analysis, the approach, measurements are usually only of the counting problem was partitioned into data center demand from type, those of time and cost.

If the solution is ever measured, government agencies, data center supply, data center it is usually compared with requirements, not with the technology, and potential solutions. The solution space business goals or the problem that needs solving.

In industrial A decision-making forum was created comprising control systems, the output can usually be compared in representatives from various agencies who could assign some direct way with the input signal. In the case of business value to the various aspects of the problem being architecture and system development, the output at any one solved.

My role as enterprise architect was to lead the time is not the intended solution but a representation of development of potential architectures and solutions, identify IBM J. The domain translation aspect is much other and against the problem. What was different from a requirements-driven strategy. Over time, agencies will be required to report on approach was the role of the architect, supported by the an increasingly more comprehensive set of parameters.

The initial achievements were focused on coordinated procurement of data center facilities Conclusion and data center migration capabilities [20]. In July , This paper has described an approach that integrates AGIMO commenced the implementation of another phase problem-solving and solution development such that the of the strategy that is aimed at optimizing the technology whole process is explicitly aimed at the business and the that is housed in government data centers [21].

I am currently problems that need to be addressed. Architecture and the lead IT architect on this project, which will, in part, system development disciplines have not kept pace with achieve its goals through standardizing and consolidating the range of problems facing businesses and government ICT services by use of cloud services and associated today.

Technology is more complex and capabilities change technologies. Zachman Framework Principle is simple: Definitions, documentation and deliverables should be organized in a matrix, 6 rows x 6 columns.

Columns represent several questions that must be answered for each of those perspectives. On each line, the multiple perspectives2,3 are: Perspective Applies to… Planner or investor perspective, to understand from a high level view Scope the shape, result, investment, timelines or methods Owner perspective, the one that will live with its daily routines, the Enterprise or team managing it.

Represents the design of the business and shows Business model business entities, processes and how they interact System architect or analyst perspective, who needs detailed System model requisites, data elements and functions that represent business entities and processes Builder perspective, who will assemble and build the components Technology model and need to understand constrains on tools, technology and materials that will be used Subcontractor perspective that will build each component without Components knowing the overall landscape, needs definitions with a programmer model detail so that objects and functions can be built User perspective or produced result.

This view represents the actual Functioning result, actual instances of the processes, team members or network enterprise elements. As stated by Zachman, the Roman Coliseum is not Architecture, is the result of Architecture On each column, the multiple dimensions are: Dimension Addressing… What information is needed?

These are the characteristics of architecture for anything. An upper row or perspective does not necessarily have a more comprehensive understanding of the whole than a lower perspective. In a project that is based upon the framework to the strategy development.

The challenges are the same. Zachman, however, indicates that only the facts needed to solve the problem under analysis need be populated.
