With the requirements determined, IT can then present their requirements to the rest of the team and begin discussions to finalize power, cooling and space requirements. If a space has not been selected, this information can be useful for identifying potential sites or spaces. If the space has been selected, discussions begin to review the types of power distribution, cooling, economization and containment. During these discussions, full team participation is imperative. Adjustments and compromises will occur; but when the full design is completed, every player should understand what is being proposed and built. There should be a sign-off on the design from each team leader and other key participants in the project.
