Differentiate between the general concepts of a risk, a requirement, a constraint, and an assumption.

From the US BrownBag Objective 1 Slide Deck:

arch-vision

and from the APAC BrownBag Session 1 Slide Deck:

rcar

Given a statement, determine whether it is a risk, requirement, a constraint, or an assumption

From this PDF:

Architectural Vision: A high level vision for the project includes the following aspects:

  1. Scope - Identify Scope in detail
    • Defined scope prevents unintended expansion (ie this project includes the US productions servers only. No dev/test and no Canada servers)
    • prevents the need to renegotiate cost of project or work for fee
  2. Goals - set specific goals for a project
    • Goals need to be specific, measurable, and actionable
    • without goals it is difficult to determine success and value of a project
    • i.e the organization wants to achieve a 50% reduction in production server equipment by the end of the year
  3. Requirements - Identify key business and technical requirements for the project
    • ie, SOX compliance, physical separation from production and dev/test, up-time requirements, etc
  4. Assumptions- Design components that are assumed valid without proof
    • i.e. the organization has sufficient bandwidth between sites for replication
  5. Constrains - constraints limit the design choices, could be a policy, process, or technical constraint
    • i.e. due to existing relationships all hardware is dell
  6. Risks - Identify risks that might prevent achieving project goals
    • i.e. lack of core redundancy introduces risk of %99.99 up-time
    • discussing risks eliminated surprise

Also good examples can be found here:

  • http://www.slideshare.net/ProfessionalVMware/professionalvmware-brownbag-jason-boche-vcapdcd-objective-1

Analyze impact of VMware best practices to identified risks, constraints, and assumptions

From the US BrownBag Objective 1 Slide Deck:

Basically try to be flexible with best practices, not everything falls under best practices or a certain criteria. For this section the Blue Print has a link to an excellent document from Glasshouse, I would definitely recommend reading it: Developing Your Virtualization Strategy and Deployment Plan
