Business Intelligence Applied: Implementing an Effective Information and Communications Technology Infrastructure

ICT Infrastructure Modeling

The first step in infrastructure modeling is to create working documents that describe the functionality intended to support the business processes of the organization. Working documents need to be created to help the business analyst and the ICT engineer envision what needs to be done to create an appropriate ICT infrastructure. These documents are created by the business analyst, who has thoroughly analyzed the organization using the tools described in previous chapters. Working documents must have the input of all stakeholders. Once the working documents (i.e., the functionality list, ICT hierarchy, and bandwidth estimates) are created, then the actual ICT infrastructure design documents can be created. The flow of these documents is shown in Exhibit 8.1. They are interlinked, with a good bit of back-and-forth between them occurring before the business analyst is ready to create the final ICT diagrams. All of the working documents and the final ICT diagram, taken together, should make a complete set of documents that the ICT engineer can use to create the technical specifications necessary to deploy the ICT infrastructure. The business analyst, the ICT engineer, and all other stakeholders need to ensure the documents are correct.
