Table 2 Stages of usability engineering
From: The impact of usable system for regression analysis in higher education
Stage | Element | Description |
|---|---|---|
Specifications | Users’ analysis | It is done to identify the users and their tasks, and the way they carry them out |
Task Identification | It is a set of techniques used to determine how users perform a specific task | |
Specifying usability | It refers to a series of usability specifications | |
Design | Interaction design | It includes a conceptual system and a visual interaction design |
Prototype | Precise system prototypes are used to be easily understood by the user | |
User’s participation | The participation at this stage can vary according to the degree of involvement, providing a User Centered Design (UCD) or Participatory Design (PD) | |
Evaluation | Usability testing | It shows the user a set of tasks to be performed with the previously designed prototype, compiling their actions and evaluation to be analyzed later |
Heuristic evaluation | This evaluation is based on experience of design or usability guidelines to point out the mistakes in the system |
