the other thread

18. Content and technical designs are merged to
produce executable web pages
Testing exercises WebApp navigation, attempts to uncover errors in
applets/scripts/forms, and checks for environment
incompatibilities

19. Each increment of the WebApp
is reviewed
Changes required by customer
are applied to next increment

20. WebE Best Practices
Take time to understand the business needs and product objectives,
even if WebApp details are vague.
Describe how users will interact with the WebApp using a scenario-
based approach.
Develop a brief project plan.
Spend time modeling what you are going to build.

21. WebE Best Practices
Review models for consistency and quality.
Use tools and technology that enable you to construct the system with
as many reusable components as possible.
Don’t rely on users to debug the WebApp, design comprehensive tests
and execute them before releasing the system.
