The reasons you are offering mobile access to your portal have a direct affect on planning your deployment. You must define target population, performance standards, and other factors related to your goals.
Identify your technical objectives by answering the following questions:
What are the goals of providing mobile access? For example, do you want to deliver a service? Do you want to provide information?
What applications will the mobile portal deliver? What is your target population?
What performance standard is necessary? Does it differ from your portal performance?
What transaction volume do you expect? What transaction volume do you expect during peak use?
What response time is acceptable during peak use?
What level of concurrency, the number of users who can be connected at any given time, is necessary?
Will your mobile portal be deployed in one phase, or many phases? Describe each phase and what will change from phase to phase.
