Analysts must assume that users have not read the manual, have not attended training, and do not have external help readily available. To confront these realities, navigation controls must be designed with basic principles. Identify and define three principles. Provide an example for each.

(1) Information Architecture (IA). (2) Identifiable and consistent Navigator        (3) Reasonable number of navigation option.

Explanation:

1) Information architecture: Its important to have a mental awareness of what the user is used too or what they might want. Can they find what they are looking for in the places they are used to from checking other sites? An analyst must be able to order the pages under different category. This can be achieved with a user group (a of targeted users that can categorize the pages). It can also be done with the use of expert tools or software. ts also important to ensure that Call To Action (CTA) leads where the user expects. There should be an obvious CTA for any command the user is willing to execute. For example, three horizontal lines arranged vertically or three dots arranged vertically in a website usually indicates options.

2) Identifiable and consistent navigator: The navigator in use should be consistent i.e. They should be where they are expected by the user. User experience is built from what they are used too. For example, most standard websites or web pages have similar navigators e.g. the logo is always at the top, another example is that ads come at the extreme sides or extreme top or bottom.

3)  Reasonable number of Navigation options:  The number of options presented must not be cumbersome. The ideal number should be between 5 and 7. Sub-options are allowed to create a friendly user experience. It's equally important to prioritize the options the user will tend to use more. Example is the settings option in a phone, there are lots of options but it has been grouped and prioritized to allow for the ones the user is familiar with.  

dude the first thing it says is that copied answers will get a zero. plus it would take anyone on an incredibly long time to answer. ive seen 2 people asking the exact same question and their questions got taken down. i have the assignment too, and im in the progress of doing it. i suggest going to a more private website, because this is the first place teachers look.
