USABILITY EVALUATION OF WEB BASED APPLICATION WEB COMMUNICATOR

V diplomskem delu smo ocenjevali uporabnost spletne aplikacije WebCommunicator, ki se razvija v podjetju Iskratel d.o.o. Uporabnost aplikacije smo ocenjevali kvalitativno in kvantitativno. Za kvalitativno ocenjevanje uporabniške prijaznosti smo uporabili tri različne metode: vprašalnik SUMI, vprašalnik SUS in hevristično evaluacijo. Pri kvantitativnem ocenjevanju smo merili čase, ki so jih uporabniki potrebovali za izpolnjevanje določenih opravil. Na koncu smo analizirali dobljene rezultate iz vseh uporabljenih metod za ocenjevanje uporabniške prijaznosti Web Communicatorja in zatem predlagali spremembe za nepravilnosti, ki so se pojavile ob ocenjevanju. Ugotovili smo, da so bili uporabniki v splošnem zadovoljni z uporabo aplikacije in da bo po odpravi vseh najdenih nepravilnosti produkt pripravljen za tržišče.In the diploma work, we evaluated the usability of the web-based application WebCommunicator, which is being developed in the company Iskratel d.o.o. Usability of the application was evaluated qualitatively and quantitatively. We used three different methods for the qualitative usability evaluation: SUMI questionnaire, SUS questionnaire and heuristic evaluation. For quantitative evaluation, we measured how long it took for the users to fulfill certain tasks. In the end, we analyzed the results obtained from all of the methods used for evaluating the usability of Web Communicator and then advocated modifications to the irregularities, which were revealed during the evaluation. We found that users were generally satisfied with WebCommunicator and that after the abolition of all the irregularities found the product will be ready for the market
