Expert review is a way for usability experts to find usability issues by using the product instead of having the subject use the product or service. Also called a heuristic evaluation.
Since no subject cooperation is required, the evaluation can be performed in a short period of time and can be performed at a relatively low cost. In addition, evaluations can be made even for evaluation targets that cannot be used by subjects, such as specifications and initial prototypes.
Evaluation by an experienced consultant
Evaluators who perform expert reviews are required to have the ability to imagine the thoughts and actions of users. Consultants who perform expert evaluations on human interfaces have experienced a number of usability tests and have observed different types of users interacting with different products and getting stuck.
Find more realistic issues
Instead of checking specifications based on checklists, we check products from the user’s perspective by doing task-based walkthroughs, so we can report more likely issues.
The standard items included in this service are as follows:
- Evaluation planning
- Evaluation implementation
We will propose an appropriate evaluation plan according to your request and various conditions.
The standard output is as follows:
Written Evaluation plan
This document describes the experimental design information necessary for conducting usability tests, such as the purpose of evaluation, scope of evaluation, method, target users, tasks, and schedule. It is also a document for confirming and agreeing on the contents of your request.
The contents of a standard report are as follows:
- Evaluation outline: Test implementation details
- Issue List: A list of issues found in usability tests.
- Issue analysis: Describes the details of the issue, the probable cause, and the direction of improvement for the issue found in the usability test.
The standard procedure is as follows:
1:Asking of purpose and requirements
We will ask you about your requirements, such as the purpose of the evaluation, the products to be evaluated, and the requirements for participants.
Based on the result of asking, we will write the plan, and have the clients check the contents, and revise.
We will extract and analyze usability issues.
We will write a report.
We will report the evaluation result and deliver the report.
