A visualization is a functional representation of the desired Web site or software system. The visualization enables designers, developers and stakeholders to experience and interact with the requirements of the desired system before any code is written. This facilitates multiple rounds of user testing and helps plan for a wide range of scenarios.
The traditional development process yields a vast amount of technical documents and complex diagrams. Someone reading these materials is required to envision what the end product will look like and how it will work. This often leads to the dreaded conundrum of misaligned expectations after the costly development phase is complete.
The visualization process removes nearly all of these cumbersome documents and diagrams and most importantly clears up any ambiguity. A visualization allows you to use and test your product during the planning stages to ensure that what will be built, is exactly what you are expecting.
This technique is a low cost approach to prototyping. Actual users can perform sample tasks and complete scenarios. Based on the findings, Acro Media can tweak and improve the system based on this early feedback; before the developers start programming.
