The best approach from a risk management perspective when implementing a large and complex data center IT infrastructure is to use a deployment plan based on sequenced phases, as this will allow the organization to break down the project into manageable and measurable stages, and to monitor and control the progress, quality, and outcomes of each phase12. A phased deployment plan can also help to reduce the risks of errors, failures, or disruptions that could affect the entire infrastructure, and to implement corrective actions or contingency plans as needed34.
