When your client asks you to evaluate existing websites or APPs when pitching, based on your expertise, usually we will not be able to conduct user testing due to various restrictions. In addition to that, you do not want to propose subjective or partial evaluation result to your client, either. Most of the time, you may think about Heuristic Evaluation (HE) proposed by Nielson, when conducting expert reviews. HE is a software usability evaluation methodology, which can conduct usability evaluation by adopting a comparatively simple, universal and heuristic usability rules.
One of the flaws of the conventional HE is that opinions among different User Experience (EX) experts are hard to reach an agreement. In addition to that, there are several “false alarms”, usability problems that are missed or non-critical usability issues. On top of that, to those usability experts, this type of session often makes them feel tedious and lack of challenge.
Pro. Helen L. Petrie and Lucy Buykx from the University of York proposed a refined version of HE: Collaborative Heuristic Evaluation (CHE). Their research proves that CHE performs quicker, and will be able to detect 3 times of the usability problems more than the traditional HE.
This evaluation methodology contains the following steps:
1.1Understand your target audience
1.2Set up page level user objective and its related user task
1.3Create data collection form
2.1 Use CHE’s heuristics to start review, according to each user task
2.2 Rate every single detected usability problem, by using the usability problem severity rating proposed by Molich and Nielsen. Record the problem and its associated rating
3. Data Analysis
3.1 Analyse result
3.2 Project the result into our check form
4.1 Present the result by the use of our framework
4.2 Create executable, constructive suggestions based on the usability problems
and their severity ratings.
We would present the methodology of how to use professional, effective and clear method to clearly present your results. We have been adopting this methodology in several projects. Abundant number of user testing verified the effectiveness and efficiency of our methodology. Therefore, we invite you to attend this workshop, offer you this tool, allowing you to improve the possibility of winning a pitch, and more recognition from both clients and colleagues within an ongoing project.
