On occasion of World Usability day today, I still have a thought
and also wonder if there are many users who are still struggling with
interfaces to perform their intended tasks and whether their voice was heard
while the interfaces were being designed, be it a website or an application
targeted for laptops, tablets or handheld devices.
The answer would still be
inclined towards a 'Yes'. There might be still a good number of unhappy users.
With such a number of sites and applications undergoing redesign, change,
content updates everyday across geographies, and for so many different target
users, there is a probability that target users in scope would not have been
available or identified to gather feedback during the design of interfaces.
In a given project, where
does the process of user feedback start and where does it end? What is the best
phase of design to have such feedback sessions with users?
Following are the possible phases to have user feedback sessions
and as part of iterative design process :
1) Wireframe/concept level (Paper, wire framing
2) Visual design level
(static jpegs images with look and feel and branding)
3) HTML prototype level
4) User Acceptance Test
5) Live version
Notably, each phase provides
different type of feedback on design in progress.
For example, concept/
wireframe phase gives user feedback primarily on basic site structure,
navigation elements, information contents, naming convention of menu.
Visual design phase provides feedback on 'look and feel', branding,
visual affordance, color and style in addition to the information architecture.
It is recommended to have such user feedback sessions preferably first during
wireframe phase. Simply, as it is easy to make changes in fundamentals of
design based on user feedback very quickly and with least efforts. The design
is still taking shape in a wire framing tool or even paper prototype.
The more delay in having
these sessions arranged in later stages of design, more team members need to
redo their work ( visual designers, HTML developers) and more cost it adds up
to the project budgets.
I believe that with the
advent of usability term used, realized and usability practice being
evangelized across organizations in different domains, user feedback would be
forming as one of the core input during design to achieve better user
