Hi Kishor, Although both are methods to evaluate any product on the aspects of usability, interaction, design, navigation etc. But they still are two completely different approaches to achieve this.
In Heuristic Evaluation, the product is simply evaluated against a set of given rules, which are more or less best practices, and gives a checklist or sometimes quantitative evaluation report on how the product's design will work. It is more of a benchmarking for the product against a given set of heuristics. Whereas, an Expert Review is more of a qualitative evaluation. In this an expert will step into user's shoes, go through whole product as a user might go, and identify and document what works in the product and what doesn't. An Expert Review is done with main focus to identify issues pertaining to design in any product and identify specific areas where these issues occur. Expert Review is widely used to evaluate a product when it is to be redesigned. The findings are then used to come up with a proposed new design. In an expert review, the reviewer brings in their expertise in usability and design, domain experience, and also sometimes their personal choices/biases. This is also a disadvantage of an expert review. There is a possibility that the outcome of this evaluation is also based on the evaluator's personal choices, or understanding of the product and its domain. I hope this helps.
