The user is likely to pull the trigger and be disappointed by the outcome.Īuthor/Copyright holder: Gibraltar Arms. It is unlikely that your gun will be a success because in all other guns – a trigger is used to fire a round. Your gun is fired by pushing a button on the side and the traditional trigger mechanism is used to chamber a round before firing. It can also help identify when a user’s expectations of an action don’t align with the actual action taken because they are using other reference points and becoming confused (for example, the use of language in your product is in common usage in other products and means something else).įor example let’s say you have invented a new gun.

This question is trying to examine whether the interface is making assumptions about a user’s level of experience or knowledge that aren’t accurate. Let’s take a look at each question more closely and see what they’re trying to achieve: Will the user try and achieve the right outcome? The assessor performs each action in any given task process and asks the four questions above. If the correct action is performed will the user see that progress is being made towards their intended outcome?.Will the user associate the correct action with the outcome they expect to achieve?.Will the user notice that the correct action is available to them?.Will the user try and achieve the right outcome?.in 2002 in their paper “Cognitive walkthrough for the Web” offer four questions to be used by an assessor during a cognitive walkthrough: The Four Questions to be Asked during a Cognitive Walkthroughīlackmon, Polson, et al. Copyright terms and licence: CC BY -SA 3.0 If the task is too complex to write in a list format – a diagram can be used instead.Īuthor/Copyright holder: Raylton P. So, for example, the log in process on a website might look like this: Tasks are then divided up into a simple process to follow. It is these tasks that the cognitive walkthrough will examine for usability – any tasks that can be performed in the product but are not subject to a cognitive walkthrough will not, normally, be assessed during the process.
PROTOTYPE 1 WALKTHROUGH HOW TO
How to Conduct a Cognitive WalkthroughĪ cognitive walkthrough begins by defining the task or tasks that the user would be expected to carry out. It can also be implemented prior to development during the design phase which can give rapid insight before budget is spent developing an unusable product. The biggest benefit of a cognitive walkthrough (or walkthroughs) is that it is extremely cost-effective and fast to carry out when compared to many other forms of usability testing.
PROTOTYPE 1 WALKTHROUGH MANUAL
The idea is that if given a choice – most users prefer to do things to learn a product rather than to read a manual or follow a set of instructions.Īuthor/Copyright holder: Paul Veugen. It is a task-specific approach to usability (in contrast to heuristic evaluation which is a more holistic usability inspection). They are designed to see whether or not a new user can easily carry out tasks within a given system. Cognitive walkthroughs are used to examine the usability of a product.
