Research methods (goms)

The GOMS model examines the amount of time required to efficiently complete an objective, focusing on each individual research method component of the user experience rather than concentrating on the system as a whole.

The acronym GOMS refers to -:


The tasks which the user is attempting to accomplish for the qualitative method


The Atomic-level actions such as cognitive processes, perceptions and other motor actions, which are required for a user to accomplish their goal


The procedures that consist of a number of operators and sub-goals that a user must perform to accomplish their overall objective

Selection Rules

The choice a user is presented with when deciding which method will best assist them to complete their objective

The GOMS method is based on human information processing theory and uses measurements of human performance to calculate the time required to complete each goal. This could be the amount of time a user requires to process a certain amount of information or the time required to decide on which action to take next. The time taken to complete each individual operation is calculated for all the operators of each method.
