As stated earlier, the focus of an analysis should ultimately be the individual end-user clients where the users do their work. You should pay close attention to the activities of end users before, during, and after the creation of your network infrastructure design.
Users' collective perceptions can have a profound impact on the reality of your project and how it is judged. Do not underestimate the power of the user community.
Analyzing end-user work needs involves determining who needs access to which data, when they need it, and where it should be delivered. It is imperative that the network infrastructure support the work needs of the end users. In order to meet end-user work needs effectively and efficiently, you must also carefully examine end-user group usage patterns. The questions to use for this phase do not consist of solid "who" and "what" questions, but rather "when," "how often," and "how much."
