Important Items to Keep in Mind
INTERACTIVE PROTOTYPING
Design with research in mind. Have a good understanding of major tasks, mental models, opportunities and the like.
Know the mission. Be sure to gain a clear understanding of the client's mission.
Accept feedback. Insight from outside sources can help push us beyond our personal boundaries and create the best experience for our users.
Plan for the unexpected. Change requests and adjustments may need to be made based on functionality abilities and/or limitations. Be willing to make those necessary adjustments, as needed.
Always provide a clear justification for your case. Show value in your results and how it would relate to the client.
Save time and money. Proper research can also potentially prevent spending unnecessary dollars, dealing with unsatisfied users, extended timelines, and so forth — that is, if the issues are caught in time during the UX process.
Iteration is the word. The creative process is never complete.
