• Identify the number of Web developers and content authors needed to develop and initially implement the solution, and identify how the team will be staffed.
• Identify the security levels needed for each type of development role.
• Identify hardware and software needs for the development team.

Defining the Technical Architecture for a Solution

Given a business scenario, identify which solution type is appropriate. Solution types are single-tier, two-tier, and n-tier.

Identify which technologies are appropriate for implementation of a given business solution.

• Select the appropriate development tools to use.
• Identify which products and technologies are appropriate for implementation.

Choose a data storage architecture. Considerations include volume; number of transactions per time slice; number of connections or sessions; scope of business requirements; extensibility requirements; reporting requirements; and number of users.

Test the feasibility of a proposed technical architecture.

• Demonstrate that business requirements are met.
• Meet existing technology constraints.
• Assess the impact and tradeoffs that result if a specific requirement is not met.

Developing the Conceptual and Logical Design

Construct a conceptual design that is based on a variety of scenarios and that includes context, workflow process, task sequence, and physical environment models.

Given a conceptual design, apply the principles of modular design to derive the components and services of the logical design.

Incorporate business rules into object design.

Designing a User Interface and User Services

Identify the logical sequence of information flow to the user.
