During the design phase, you map the logical components specified in the logical architecture to physical components in a deployment architecture. You also produce design documents that aid in the implementation of the deployment. Successful deployment design results in the following:
Project approval is typically based on design documents created during this phase. During project approval, the cost of the deployment is assessed, and if approved, contracts for implementation of the deployment are signed, and resources to build the project acquired. At what point the actual approval occurs depends on the type of deployment you are designing and internal policies of the company requesting the deployment.
The deployment architecture is a high level design document that represents the mapping of logical components to network hardware and software.
The implementation specification is a set of design documents that includes the following:
A detailed design specification used as a blueprint for building out the deployment
A user management plan outlining procedures for designing and implementing directory services and data structures needed to provision users for access to system services
An installation plan that outlines procedures for distributed installation of the deployment
Additional plans covering phased rollout of the deployment, training for end users and administrators, and other plans related to a successful introduction of the deployment
