Here are my recent responses to questions on Enterprise Architecture asked by fellow EA's on Quora. Do keep the questions coming. I will try and respond here or on Quora or Linkedin Pulse.
Like most professional groups, the Open Group periodically updates the focus based on emerging body of knowledge.
You should decouple the timing of “new updates” from the reason why you are trying to get certified. You are trying to get certified to gain knowledge and skills, and demonstrate the abilities to current and prospective employers.
With this in mind, one can argue now is a good time as any to go for a TOGAF certification!
Why do big companies fear using SaaS products?
Not all large enterprises are hesitant to adopt SaaS solutions. However, the adoption in some companies operating in highly regulated environments may be slower than the rest.
SalesForce. com has been reporting record profits due to wider adoption of its SaaS CRM platform by large, multinational corporations. In my role of an Enterprise Architect for a multinational, I have been involved in evaluating SaaS solutions for several functional capabilities.
Check out my recent blog post on the topic: Evaluating SaaS solutions? Watch for these 5 challenges The key watchouts/points I highlight include:
#1. Configurations and customizations can add to cost and complexity
#2. Synchronizing upgrade calendars
#3. Don’t underestimate integration complexity
#4. Do not underestimate the need for a “service” to manage the SaaS service
#5. Watchout for the TCO
What is the best source for successful examples of real life it-architecture products e.g. system definitions, UML diagrams, Business Processes?
Agree with Eduardo . Many of the corporate artifacts are and generally not published. IT Consulting firms manage their internal knowledge repositories where consultants share artifacts with colleagues (after scrubbing client specific details).
Perhaps the best source for general reference is the DODAF artifact list (DODAF Viewpoints and Models) And DODAF references published by vendors e.g An IBM Rational approach to the Department of Defense Architecture Framework (DoDAF) Part 1: Operational view
