In this video we are going to introduce a technique called Heuristic Evaluation. As we talked about at the beginning of the course‚ there’s lots of different ways to evaluate software. One that you might be most familiar with is empirical methods‚ where‚ of some level of formality‚ you have actual people trying out your software. It’s also possible to have formal methods‚ where you’re building a model of how people behave in a particular situation‚ and that enables you to predict how different

Judgmental heuristics are principles or methods by which one makes assessments or judgments of probability simpler. These heuristic are often very useful but sometimes they lead to systematic errors. In activity #1 A- the principle that is used is the representativeness heuristics it uses an event which is judged to be probable to the extent that it represents the essential features of the parent population or of its generating process (garns).

Heuristics are strategies which reduce the complex tasks of assessing probabilities and predicting values to simpler judgmental operations (Tversky & Kahneman‚ 1974). It is also a technique to arrive at satisfactory solutions with the modest amount of processing‚ implying that people seek to reduce the effort associated with decision processes (Simon‚ 1990). Therefore‚ heuristics use principles of effort-reduction and simplification
