Review the sample project
Take some time to review the sample project and compare it to the stated parameters in its introduction and with the guidance provided earlier in the chapter. Take notice both of what is there and what isn't there.
The Success Metrics portion is easily the longest section, and in an actual project would be much longer. It is intentionally quite specific in nature. Filling this portion with seemingly minute details can help ensure that no stone is left unturned and that no eventuality is unplanned for. If this section is properly laid out and all of its conditions met, you are virtually guaranteed a successful deployment free of surprises.
Even though the introductory material discussed virtual desktops, there is no mention of it in the Goals or Purposes sections. While not directly stated, it is inferred that VDI is a nice-to-have feature, not a primary driver. This would be a prime example of an opportunity to set limits on the scope of the project. As you can see, each item in the project goals translates directly to a large number of success metrics, so there is a definite benefit in restricting how much you take on. In this case, the director that initiated the project has indicated that this is a pilot, which implies that it is expected that if the deployment is successful, it will be expanded at a later date. The fictitious systems administrator tasked with writing this document has elected to try to hold off on a VDI implementation for a later expansion project.
Even though the formal document skips over VDI, the project notes should contain reference to it. The director did indicate his desire to have a single large cluster to handle anything that the company chooses to virtualize. If there are any special requirements of a VDI deployment that the initial hardware cannot satisfy, then it may be difficult to meet the director's desire for a single cluster. The decision will need to be made to expend resources to ensure that the initial hardware can handle any load that would ever be expected of it or to assess the feasibility of a single cluster versus two (or more) and against the usage of a single cluster augmented by one or more standalone Hyper-V Server systems. One way to bring this into the formal document would be to introduce it as a "Desirable" goal.
As it stands, this project document would be considered to be in draft form. The author was able to make some practical decisions regarding its contents and layout, but encountered at least one decision point that will need to be handled at a higher level and/or by group discussion. This should only be considered a beginning point for the planning phase, not the end.
Once these initial portions of the plan have been approved, the next step is to outline the remaining phases and the timelines they will be completed in. Those are procedural processes whose execution will depend upon your organization's operations.
