Validating Enterprise Architectures

Enterprise system architectures would be the corner stone of major IT investments and therefore possess a lengthy term effect on a corporation’s main point here. Acceptance from the enterprise system architectures by all stake holders is essential towards the effective implementation from the architecture. Validation of system architectures with stakeholder expectations is really a best practice frequently adopted by good enterprise architects.

This white-colored paper outlines the fundamental facets of the validation process and offers a justification why enterprise architects should make up the practice of validating the architectures they build or define. This white-colored paper also suggests some specific approaches for performing validations from the essential facets of enterprise system architectures.

A side purpose of this white-colored paper would be to stimulate discussions and discussing of real life encounters of initiating, performing, and also the overall impact of presenting the validation results. All these major tasks from the validation process is definitely an uphill fight requiring technical understanding and depth, political awareness and individuals management techniques.

Since many practicing architects eventually realize, doing the best factor isn’t easy, nor is that this procedure for validating enterprise system architectures. Hopefully this white-colored paper will trigger feedback that can help all enterprise architects cope with this problem and start the entire process of validating (stake holder approval, acceptance, and adoption) enterprise system architectures.

The necessity to Validate Enterprise System Architectures

This might seem very familiar to many enterprise architects but validating enterprise system architectures isn’t an activity present in most project plans. Yes, the validation process isn’t always quick neither is it of short duration. However, it’s very important the first step toward enterprise systems, namely the machine architecture where major investment of your time, money, and sources is committed, is correctly validated before time runs out.

System architectures are artifacts formed with the personal biases from the enterprise architect accountable for developing the architecture. Past encounters, current understanding, along with a very personal knowledge of the objectives from the enterprise system to become built play a large role in shaping the architects mind and therefore the machine architecture. Not validating system architectures means following a view reason for the architect or even the architecture team which come up with the machine architecture under consideration.

Validating system architectures can also be hugely advantageous towards the enterprise architect because it helps bring all stake holders and leaders together and facilitate a gathering of minds making certain lengthy term investment and support for that project. No project goes as planned and getting this sort of over-all support is crucial to the enterprise project particularly when everything doesn’t go as planned.

A good thing oriented look at systems and architectures

Enterprise architects, who see the systems they develop as software assets, have a tendency to include validations to their plans. Assets are made having a lengthy term vision in your mind and therefore are envisioned having a lengthy lifecycle. Hence it’s natural for enterprise software asset architects to know the significance of being assured the lengthy term direction set through the system architecture has backing all stake holders, is reasonable in the corporation’s perspective, and can really deliver on everybody expectations.

It’s not easy to define perfect system architecture as most of the parameters involved with developing that architecture can change within the lifecycle from the system. However validated system architectures possess the capacity to rapidly result in the necessary midstream adjustments without losing focus from the finish goals.

Hence, enterprise architects should cultivate the habit of smoking of treating every system they architect like a lengthy term software asset and take validation of the architectures seriously. The following couple of pages of the white-colored paper discuss the entire process of validating enterprise system architects, and the way to validate specific proper facets of the machine architecture.

The entire process of Validating Enterprise System Architectures

Defining the right process for validating enterprise system architectures doesn’t need lots of advanced thinking or process engineering. The operation is basically simple, composed of good sense tasks. However, planning and executing on these good sense tasks could be surprisingly challenging to have an enterprise architect because it depends upon the fermentation from the corporation’s knowledge of the function of enterprise system architectures.

Figure 1. presents one particular good sense approach which involves three major tasks.

o Initiating an architecture validation

o Performing the particular validation from the architecture

o Assessing the outcomes from the validation

Figure 1: A typical sense method of validation process

All these apparently simple and easy , easy tasks could possibly get complicated because of corporate politics. The greatest obstacle becomes the acceptance from the results and also the eventual sign-from the enterprise system architecture. This is particularly hard for stakeholders who don’t share exactly the same degree of knowledge of architectures because the enterprise architect. Frequently, enterprise architects have trouble convincing stakeholders about the requirement for validating system architecture just before commitment of major IT investments.

Stakeholder understanding of the validation process and particularly from the outcomes of the processes is very important. Effective enterprise architects are routinely capable of getting stakeholder support to incorporate architecture validations included in the overall master project plans. The goal of the remainder of this white-colored paper would be to help enterprise architects produce the necessary understanding of what must be validated, the way the validation is going to be performed and also the expected together with your overall effort.

What Essential Facets of Enterprise System Architectures Don’t Let Validate?

There are lots of aspects to some system architecture including technical and business oriented and some management oriented aspects for example implementation roadmaps. However validating all these aspects is neither practical nor essential for making certain the machine architecture applies and can set the right lengthy term direction for that enterprise system. You will find couple of proper facets of the architecture that when validated possess a cascading effect on the rest of the architecture aspects and growth and development of the program asset. The very best three proper and essential facets of enterprise system architecture that warrant validation are outlined below.

1. Probability and Degree of “Adoption Risk”

Most forward searching and lengthy term enterprise architects depends upon adoption of recent technologies, development techniques, and heavy lengthy term participation of finish users. These dependencies on adopting something totally new, reengineering existing processes etc. have a greater possibility of risk towards the project. Understanding this “Adoption Risk” is crucial to secure lengthy term support all stakeholders. Pointless to state not getting an entire picture from the risks involved will surprise stakeholders and also the project is going to be in danger. It’s the job of every enterprise architect to first identify these risks after which validate the architecture’s contact with these risks by defining appropriate minimization strategies.

2. Affordability

Just how much is that this architecture likely to cost throughout its lifecycle? This can be a question most architects hope nobody asks as it is very hard in other words difficult for estimating precisely the price of a lengthy term project. Yes, enterprise architects must have the abilities for supplying sensible cost estimates that’ll be acceptable to any or all stakeholders. These estimates have to be nearer to reality than fiction and therefore understanding aspects that may potentially influence the price of the work within the lengthy term have to be validated included in the architecture.

3. Stakeholder Participation

Do all of the stake holders understand, agree and accept the machine architecture? Now this rarely happens and many architects will state that looking to get all stakeholders to agree with one architecture isn’t realistic. However, participation all stakeholders is vital towards the lengthy term success of enterprise projects and enterprise architects should spend some time to know the main motorists and scope of every stakeholder active in the enterprise project.

Validating “Adoption Risk”

As previously mentioned, enterprise system architecture is really a composition of numerous different factors. All these aspects features its own lifecycle and also the suggested system architecture will contain aspects which are each inside a different condition of the individual lifecycle. Figure 2. presents a simplified view composed of two aspects, the total cost of choosing specific system architecture and also the general adoption rate of recent technologies

The danger measurement chart shows two key aspects that may influence the machine architecture one of the ways or another. The very first aspect relates to the technologies incorporated within the system architecture. Usually there’s a combination of technologies varying from some within the infancy stage of the lifecycles with other technologies that tend toward becoming obsolete within the lifecycle from the architecture. In most cases early adoption of recent technologies has slightly less risk as there’s room for adjustments because the technology matures. Late adoption of technologies poses a greater risk as technology is becoming obsolete in a considerably faster rate.

Another aspect that enterprise architects should element in their validation is the price of supporting obsolete or near obsolete technologies. Worthwhile enterprise system architecture has considered the price of replacing obsolete technologies with emerging or mature technologies within the duration of the program asset.

The aim of enterprise architects ought to be to have a nutritious balance of technologies with many of them falling in the heart of the graph representing mature condition technologies.

Validating Affordability

Making certain a proper mixture of mature technologies is an indication of excellent architecture, however every of architectures don’t get approved when the pricing is prohibitive. The larger danger however happens when architects don’t realize the lifetime price of specific system architectures. It is a lot more painful to any or all stakeholders including enterprise architects when enterprise projects are aborted because of investments not generating expected results in order to place it in correct jargon, no roi (Return on investment). A substantial element in making certain Return on investment is setting the best perspective and proper expectations. Figure 3. presents a multi dimensional look at what enterprise architects should think about when calculating the expense connected with adopting system architectures.

Most architects look so far as acquisition and maintenance phase for calculating the general costs of developing the enterprise system, obtaining the needed licenses and looking after the machine. However, a far more significant look at calculating costs may also range from the substitute phase from the software asset. In the end, all technologies eventually be obsolete and therefore are substituted with entirely technology or enhanced versions of the identical technology.

Most enterprise architects will agree that lots of occasions the substitute price of an application asset is a lot greater compared to acquisition and maintenance costs. The total cost (time, money, sources) needed to build up, maintain, and switch the software asset ought to be forecasted throughout the system architecture validation phase. The main focus isn’t to reduce the expense always but attempting to get more tasks completed clearness around the costs through the lifecycle from the software asset.

Validating Stakeholder Participation

So you’ve covered your bases around the adoption risk front, and possess clearness around the lifetime costs of following a software architecture, but they are everybody onboard? The number of occasions have enterprise architects been surprised at late objections or key stakeholders withdrawing their support in the last second? Sometimes support for enterprise projects dies out because of factors past the sphere of influence from the enterprise architect. However it always keeps all of the stakeholders conscious of the machine architecture and also the lengthy term goals regularly. It is essential for enterprise architects to know there are many major constituents whose lengthy term participation is completely essential for the continuing success of enterprise projects. Figure 4. is definitely the stakeholder quadrant composed from the key stakeholder groups and also the architecture scope directly affected by such groups. Each stakeholder group is really a composition of appropriate leadership, management, and staff.

Each view is itself a world of processes, objects, and condition that should be enabled and based on the machine architecture. Validating the machine architecture across these views is crucial for those stakeholders to stay in agreement their interests are taken proper care of. Enterprise architects should be ready to initiate and finish this burdensome task.


Validating enterprise architectures is a crucial element of making certain lengthy term effective implementations for enterprise systems. The very best enterprise system architectures neglect to deliver when defined in isolation. The validation process is basically about involving all stake holders and becoming their acceptance and adoption from the architecture.
