This article demonstrates the heuristic evaluation process interface used in Shopping + application. Considering that the system development cycle can often be long, the different types of interfaces usability evaluations should be performed during the same development process, in order to minimize errors and reduce system production costs the process. Heuristic evaluation created by Jacob Nielsen is one of the best-known usability evaluations and is highlighted by its easy implementation and low cost. In it, the experts assess the interface and the system based dialogue on a set of principles, heuristics, for identifying usability problems.
