After your presentation last week, the manager thought an in$-$house solution was the way to go$.$ Although our programmers have much experience with system integration and development, they have little experience with user design. You'll have to lay out all the pages of the system. For now, create a hierarchical drawing of all the pages needed for this system. Think of the menu on the top of the screen and what you'd click on to move to the next screen.

Once you finish the hierarchy, I'll need you to draw examples of a few screens. For example, show a screen with a menu, another requesting user input, one with methods to contact us$,$ and the last as an informational page. The menu screen can be an opening page or even a page to decide the types of reports to run. The user input page can be one for users, such as appointment setters or technicians. Ensure you outline all of the required validation rules for this input page. The informational page can either be a static page or results from a search. Make sure that you include navigation buttons on each of these example pages. I think it would be a nice touch to include our logo on all of these screens.

Please answer the following question in detail, including an introduction, an example, a conclusion, and links to related research articles. Give a physical example.
