1. Executive summary:
The first step in the user design process is to research a few important subjects
to get a feel of the overall system and how it will look. The following are some
interesting subjects to investigate:
The summary - this section outlines the user's or product owner's expectations
for the system. It's tough to have a clear image of how the system will operate
while you're in the inquiry and consultation stage because there's usually a
disconnect between what people want to see and what they'll get.
You will be able to obtain information from the product owner's perspective, such
as target audience, including but not limited to 'age, specialties, location, and
employment' to give an idea of the user's profile, when documenting the brief;
however, you will not be able to obtain information that gives you a clear
indication of what the user will do when they receive the system. It's simply a
stab in the dark.
User persona parameters are non-contextual and are based on a pre-defined
profile of who the user could be. This kind of data is usually inaccurate and relies
on several assumptions. If you're creating a system to educate young girls how to
use computers for the first time, we'd go with warm, soft color palettes that are
very female, and blue with the boy child. However, this phenomenon is the result
of a marketing strategy and cultural indoctrination, and there are several
inconsistencies in that idea, particularly when ethnicity and background are
considered.
So, believing that a young person from a culture where red clothing is worn will
immediately feel good while using a blue interface since blue is associated with
trust according to color psychology (uxplanet.org) is wrong.
Following that, we'll see how various factors must be considered when evaluating
user responses and feelings. In my perspective, only what you have experienced
can be believed, which means we need to do a physical experiment to identify
the types of feelings they have in a neutral, non-stimulating environment.
External stimuli should not be regarded neutral, such as evaluating UX after a
user has eaten chocolate cake.
2. Drawbacks
of Cognitive Walkthrough
a. It can be very sl
ow and time consuming when it is used on very large and complex
systems.
b. Cognitive Walkthrough does not provide a high-level view of systems. Cognitive
Walkthrough does not provide a clear indication of whether a user was aware of
the existence of a function or that the interface gave users a clue that the function
is there. Therefore, Cognitive Walkthrough pays more attention to how operations

that are needed to execute a certain task follow one another but does not evaluate
the function itself. If the user isn’t aware of the existence of that functions or if the
user interface does not inform the user of its existence the user will not be able to
