DIEB14.1 Kursusgang 14 Tidsforbrug til en usability-evaluering Oversigt: Sidste kursusgang Opgaver Aktiviteter Erfaringer med tidsforbrug Instant Data Analysis

DIEB14.2 Kursusgang 14 Oversigt: Aktiviteter ­ Aktiviteter i usability-evalueringen Erfaringer med tidsforbrug Instant Data Analysis

DIEB14.3 Usability-evaluering: Aktiviteter Form: formative/summative When in development process: Exploratory Assessment Validation Comparison Participants and roles Location and equipment Determine basics Plan evaluation Prepare tests Interpret data Conduct tests Recreation of context Selection of test subjects Design of tasks Evaluation plan: Purpose Key questions User profile Participants and roles Test methods Task list Context and equipment Data to be collected Report structure Each user: Introduction Task solving Data collection Logging Debriefing Transcription of log files Data summary Data analysis Documentation (report)

DIEB14.4 Kursusgang 14 Oversigt: Aktiviteter Erfaringer med tidsforbrug ­ CUE-2 ­ Vores eksperimenter Instant Data Analysis

DIEB14.5 Erfaringer med tidsforbrug Rolf Molich: eksperimenter med usability-evalueringer Systematisk opsamling af data Tilgængelige for alle: ­ cue.html

DIEB14.6 CUE-2: Tænke-højt kontra Heuristisk inspektion 8 laboratorier testede web- stedet ­ Professionelle firmaer ­ Forskningsmiljøer ­ Studerende Testen skulle omfatte et antal specificerede funktioner Selve udførelsen kunne tilrettelægges frit Formålet var at undersøge kvaliteten af brugbarhedstest 1 af laboratorierne indgik ikke seriøst i undersøgelsen 6 af laboratorierne baserede deres evaluering på test med brugere ­ De fandt mellem 17 og 75 problemer af forskellige kategorier 1 af laboratorierne baserede deres evaluering på en kombination af heuristisk inspektion og test med brugere ­ De fandt 150 problemer ­ De beskrives tit med formuleringen “might be a problem” ­ 107 af deres problemer findes ikke af nogen af de andre ­ De finder 19 ud af 26 “core problems” men uklart hvordan

DIEB14.7 CUE-2: Resultater

DIEB14.8 CUE-2 tal Ikke alle opsamlede systematisk data om tidsforbrug Andre tal: timer for en total evaluering med 6-8 brugere og systematisk dataanalyse ABCDEFGHJGennemsnit Forberedelse Testing Analyse og rapportering Samlet tidsforbrug

DIEB14.9 Vores eksperimenter Vi har lavet et antal eksperimenter med evalueringsmetoder. I den forbindelse har vi målt tidsforbrug
