An informal review is the most common and widely used review technique. There are so many advantages of informal review over a formal and well-documented review but the key advantage is time-saving. To conduct the informal review documentation, minimum number of members or entry criteria etc. are not mandatory so this can be considered as a better way of review.
Types of Informal Review

A technical review is a discussion meeting that focuses on achieving consensus about the technical content of a document. This is an informal type of review so less process and documents are needed for this type of review. There is little or no focus on defect identification on the basis of the referenced document, intended readership, and rules. During technical reviews, defects are found by experts, who focus on the content of the document. The experts that are needed for a technical review are, for example, architects, chief designers and key users.No management participation required in technical review. More formal characteristics such as the use of checklists and logging list or issue log are optional
An informal review is commonly used and followed on regular basis in various organizations.
