LAB 3: EVALUATION TECHNIQUES

( On Existing Software) Duration :2 Hours

Learning Outcomes CLO : 3

By the end of this laboratory session, you should be able to: 1. Test usability and functionality of system 2. Considering learn ability of the system 3. Related to both functionality and usability of the design 4. Evaluate designs against requirements 5. Initiate and accomplish a task (functionality) Hardware/ Software: e-Learning Website

THEORY

Evaluation Techniques • Observational Techniques

• Think Aloud user observed performing task user asked to describe what he is doing and why, what he thinks is happening etc.

• Cooperative evaluation variation on think aloud user collaborates in evaluation both user and evaluator can ask each other questions throughout

• Protocol analysis Mixed use in practice. audio/video transcription difficult and requires skill. Some automatic support tools available

• Automated analysis Workplace project Post task walkthrough

• Query Techniques

• Interviews analyst questions user on one-to -one basis usually based on prepared questions informal, subjective and relatively cheap

• Questionnaires Set of fixed questions given to users

ACTIVITY : Activity Outcome: Evaluate a website based on title given.
