ABC model (software)

from Wikipedia, the free encyclopedia

The ABC model forms a basis for defining ergonomic principles of programming in the IT area . It was first portrayed in 1989 by Michael Frese and Felix C. Brodbeck .

starting point

The operation of programs is divided into two aspects:

  • The user wants to implement a task.
  • The user wants to use a computer to solve it.

The link between the interaction with the user interface and the handling of the task is recorded in the ABC model.

model

The ABC model represents a relationship between the task itself, the user and the computer. In the context of software ergonomics , it illustrates the possibilities of designing, evaluating and designing interactive components. In particular, the design of the dialogue proves to be the key point of the most ergonomic implementation possible. Questions arise about adapting the graphical user interface, the menu levels, the choice of fonts and colors, or even gesture control on smartphones.

The simple ABC model is taken up in the ISO 9241 standard and described further.

ABC model by Oppermann & Reiterer

The dialogue design approaches shown in the ABC model are:

  • Task appropriateness: A system must provide the functions necessary to solve the task and should therefore reduce work
  • User: A system should be manageable and easy to learn, intuitive to use and understandable.
  • Computer: A system should be accessible and manageable for the user, and it should help to perform tasks.

Adaptation of the system to the abilities of the user and to the principles of workplace design should be given.
