? Deadline: Monday, 21st June 12 PM (noon)
? Goals: Continue building your prototype and prepare a heuristic evaluation
- Continue to improve your high-fidelity prototype.
- Conduct the first and second phases of a heuristic evaluation and prepare to continue with phases 3, and 4 during the next lab session.
- You will evaluate the prototype of another group.
- Who evaluates whom? The following groups evaluate each other:
1+5, 2+6, 3+7, 4+8 - Use the slides of the lecture „Evaluation: Inspections and Quantification (9-1)“ as a preparation guideline.
Phase 1: Prepare
Use the Nielsen’s Heuristics presented in the lecture.
(optional)Alternatively, if you want to dive a bit deeper into heuristics, you can use the heuristics of Tognazzini or Shneiderman. Decides what fits best in your case and explain why.- Summary of heuristics (PDF)
- Heuristics with additional examples (PDF)
Prepare the tasks for the evaluators.
- HINT: The other group should have already a list from other test sessions, please reuse and adapt!
- Example: Tasks for evaluators (PDF – box.fu)
Please use an (online) form to collect the violations by each evaluator in a systematic way.
- You can copy and adapt the following template or redo it with some tool of your choice (e.g. lime survey, Typeform).
- Template: https://docs.google.com/forms/d/19Ndyu034h3idQSFEHwwIWbJ58RUQggVjWiE1U0czfrw/edit?usp=sharing
Prepare so everybody can take screenshots and is able to link them in the previous form.
- Tool suggestions: You could use Monosnap, FireShot, „Explain and send screenshots“-Chrome AddOn, to make screenshots and create a share link.
Don’t forget: You need to get access to the application of the other group!
Phase 2: Evaluate (Individual Inspection)
- Carry out the individual inspection using the prepared documents.
- Document your violations using your adapted form.
- All team members should carry out the individual inspection. This should be calculated with 45 minutes per person (max. 1 hour).
Documentation and Reflection
Document and reflect your process and list the files/documents you used during evaluation in the blog post.
Hint: The group discussion (Phase 3) will take place during the next lab session. Prepare for that.
