13.2. Characteristics of Interactive Systems

Interactive systems and web application are characterized by the following factors:
  • Immediacy of the customer
  • Implied promise of rapid delivery at competitive prices
  • Increasing requirement for accessibility

However the success depends on the created perception in the minds of the users. After all, it is the user who decides the quality of the site. The users have abandoned a site or a purchase of a product because of the following reasons:
  • Difficult to use
  • Broken Workflow
  • Slow to respond
  • Did not trust it to be secure
  • Content is confusing
  • Improper processing
As the final judgment regarding the application and its performance is made by the users, it is imperative for the organization developing the application, to understand, how usable the application is for its target audience. In order to address this in every application, designers have know their users, know their goals, and know the circumstances of system use. The usability of a product is affected not only by the features of the product itself, but also by the characteristics of the users, the tasks they are carrying out, and the technical, organizational and physical environment in which the product is used. In this guide, we use the term 'context' to include all factors, which affect the usability of the product, excluding the features of the product itself. We use the term 'product' to represent any interactive system or device designed to support the performance of users' tasks.
