The need to do an architecture assessment in 2007 is really critical especially if you're planning on doing a Windows Vista upgrade this year or next. Taking stock of what's what in your architecture prior to beginning any major software or hardware upgrade isn't just smart – it is a necessity.
For sure, an architecture assessment is a big task and can be quite daunting-- but remember this! Doing such an assessment will benefit your organization in the long run.
An enterprise architecture is the set of plans that describes how all parts of the IT infrastructure need to behave or currently behave in support of the organization's needs and goals. It includes an evaluation of all the data, the functions, the technology and the people that constitute the infrastructure.
An architecture assessment is the process of collecting and analyzing data about the current state of an enterprise architecture, drawing conclusions about how well it supports the enterprise, and reporting the results.
What is the value?
Undertaking an IT architecture assessment is valuable in many ways:
The bottom line is that an assessment often provides the business case data and the impetus to fund an organization's re-architecture since an assessment provides a relatively objective look at what needs to be kept or changed and why.
It helps to clarify how the current architecture contributes to perceived business problems or how it positively supports an organization's goals. An assessment looks at both what is working and what is not. It allows for a fact-based understanding of the costs and benefits of the current IT infrastructure to the organization. This is valuable even if you don't need to make changes; you'll have the facts to support your methodology for your current architecture. Because problems with the current infrastructure come to light, an assessment helps identify where re-architecting can reduce business costs, improve business functionality or processes and improve IT efficiency (e.g., reduce IT costs, eliminate duplication).
I'll write more about what is required to undertake and assessment and, most importantly, how to sell your re-architecture plans to upper management.
