Standard heuristic evaluation (SHE) continues to be very popular evaluation method in spite of serious criticisms of its validity and reliability. The paper proposes a new collaborative heuristic evaluation (CHE) and presents a study that shows the increased reliability and effectiveness of CHE in comparison to SHE. Presentation given at 9:30 on Thursday 27 May by Helen Petrie and Lucy Buykx.

Notas do Editor
- SHE: E1 – 19 problems unique to that evaluator; 2 agreed with E5, 1 agreed with both E2 and E5 …and so on … none where all 5 agree CHE: 59 all five agree, 5 E6, E7, E10 not E9 or E8; 1 E6, E8 only
- Hertzum and Jacobsen (2001) argue that this any-two agreement is the best measure of evaluator effect
- 25 mins strict matching : same design element, same problem, same level abstraction Often needed the video to place the element - remember i wrote words agreed by eval so without video would have been really difficult
