UX Design Process and Philosophy
Research: One of my favorite parts of user experience is the ability to do research. The amount of time spent on research will of course depend on a client’s needs or the scope of a project. In some situations I might perform a competitive analysis where I review a competitor’s product to find positive and negative attributes. In other situation I might do a simple heuristic evaluation that involves finding usability issues in the design so that the issues can be resolved as part of an iterative user-centered design process. Researching best practices is also important to stay up to date with current design trends.
Personas: To better relate to users and develop appropriate use case scenarios, I use personas. Personas are representations based off particular user or demographic groups.
Interviews: Additionally, it is important to seek out advice and opinions from those who know a solution best: the users. Users might be interviewed to understand what they want, like, or dislike about a solution. Subject Matter Experts (SMEs) are also an invaluable resource to provide insight when designing solutions based off business requirements.
Deliverables: In addition to research, key components to UX are the actual deliverables such as sketches, wireframes, and quantitative and qualitative analysis of an user experience.
Sketch: A quick and easy method – simply paper and a pencil or pen.
Wireframes and Interactive Prototypes: Think of wireframes as the blueprints to the placement of buttons, pictures, text, and various other objects. Wireframing does not equal graphic design! Wireframes can be as basic as a paper sketch to as advanced as a working prototype. I try to avoid color and other graphics to keep the focus on the layout.
User and Usability Testing: Depending on a variety of factors such as time, budget, and scope, usability testing can be a great resource. Usability tests generally involve real users who are typically paid to test your design in which participants are recorded and asked to perform specific tasks. Valuable insight is gained in such sessions that one might typically be unaware. Evaluators must be careful to not guide a user in completing a task in order to prevent the evaluator from influencing the test.
Iterate: UX is best when designed in a collaborative team environment where I can seek feedback from others. Iteration is also based off usability testing and design review.
Conclusion: For success and to reduce cost, it is important to begin the UX process early. The above is just a brief overview of my user experience design process and does not include every tool or method that I might use. My methodology might also vary from situation to situation.
