VCAP5-DCD Objective 1.3 – Determine Risks, Constraints, and Assumptions
Differentiate between the general concepts of a risk, a requirement, a constraint, and an assumption.
From the US BrownBag Objective 1 Slide Deck:
and from the APAC BrownBag Session 1 Slide Deck:
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:
- 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
- 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
- Requirements - Identify key business and technical requirements for the project
- ie, SOX compliance, physical separation from production and dev/test, up-time requirements, etc
- Assumptions- Design components that are assumed valid without proof
- i.e. the organization has sufficient bandwidth between sites for replication
- Constrains - constraints limit the design choices, could be a policy, process, or technical constraint
- i.e. due to existing relationships all hardware is dell
- 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

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
