Hi Lesiana, After your presentation last week, the manager thinks an in-house solution is 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, just 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 out examples of a few of the screens. For example, show a screen with a menu, another which requests user input, one that has methods to contact us, and the last one as an informational page. The menu screen can be an opening page or even a page to decide on types of reports to run. The user input page can be one for any of the users, such as the appointment setters or technicians. Make sure that 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.

Hierarchical drawing is also known as Layered Graph Drawing which includes the drawing in the vertices and are made on the Horizontal rows and layers.

The complete solution is attached below.

The In-House solutions' hierarchical diagram covers four categories, including product, service, training, support, and about.
