In software engineering
Software engineering is a systematic engineering approach to software development.
A software engineer is a person who applies the principles of software engineering to design, develop, maintain, test, and evaluate computer software. The term ' ...
, a walkthrough or walk-through is a form of
software peer review
In software development, peer review is a type of software review in which a work product (document, code, or other) is examined by author's colleagues, in order to evaluate the work product's technical content and quality.

"in which a designer or programmer leads members of the development team and other interested parties through a software product, and the participants ask questions and make comments about possible errors, violation of development standards, and other problems".

source code
In computing, source code, or simply code, is any collection of code, with or without comment (computer programming), comments, written using a human-readable programming language, usually as plain text. The source code of a Computer program, p ...

A walkthrough differs from
software technical reviews in its openness of structure and its objective of familiarization. It differs from

Process
A walkthrough may be quite informal, or may follow the process detailed in IEEE 1028 and outlined in the article on
software review
A software review is "a process or meeting during which a software product is examined by a project personnel, managers, users, customers, user representatives, or other interested parties for comment or approval".IEEE Std . 1028-1997, "IEEE Standa ...

Objectives and participants
In general, a walkthrough has one or two broad objectives: to gain feedback about the technical quality or content of the document; and/or to familiarize the audience with the content.
A walkthrough is normally organized and directed by the author of the technical document. Any combination of interested or technically qualified personnel (from within or outside the project) may be included as seems appropriate.
IEEE 1028
[ recommends three specialist roles in a walkthrough:
*The author, who presents the software product in step-by-step manner at the walk-through meeting, and is probably responsible for completing most action items;
*The walkthrough leader, who conducts the walkthrough, handles administrative tasks, and ensures orderly conduct (and who is often the Author); and
*The recorder, who notes all anomalies (potential defects), decisions, and action items identified during the walkthrough meetings.
