Chapter 3 Identifying and Evaluating Your Business and Technical Requirements 53
Technical Goals
Your technical requirement (often called functional requirement) discuss the
details of your organization’s system needs and desired results, and include such
factors as:
•Performance
•Security
• Reliability
• Expected performance criteria of the portal
The technical requirements define all functions required of an architecture and
provide guidelines for how each component works and integrates to form an entire
system. Your organization needs technical requirements to formulate the best
design approaches and apply the appropriate technologies to accomplish the
desired architectural solution for your portal.
The reasons you are offering your portal have a direct affect on how you
implement your portal. You must define target population, performance
standards, and other factors related to your goals.
Use these questions to help you identify the goals of your portal:
• What is your portal’s biggest priority?
• What applications will the portal deliver?
• What is your target population?
• What performance standard is necessary?
• What transaction volume do you expect? What transaction volume do you
expect during peak use?
• What response time is acceptable during peak use?
• What is the necesary level of concurrency? Concurrency is the number of users
who can be connected at any given time?
• Should access to the portal be through intranet or Internet?
• Will your portal be deployed in one phase, or many phases? (Describe each
phase and what will change from phase to phase.)
