Walkthrough

This article from wikipedia. Walkthrough, or walk-through, is a term describing the consideration of a process at an abstract level.

The term is often employed in the software industry (see software walkthrough) to describe the process of inspecting algorithms and source code by following paths through the algorithms or code as determined by input conditions and choices made along the way. The purpose of such code walkthroughs is generally to provide assurance of the fitness for purpose of the algorithm or code; and occasionally to assess the competence or output of an individual or team.

The term is employed in the theatrical and entertainment industry to describe a rehearsal where the major issues of choreography and interaction are practiced and resolved, prior to more formal "dress rehearsals".

The term is often used in the world of learning where a tutor/trainer will walk through the process for the first time. It is regarded as a literal walk through of the learning at the groups pace ensuring that everyone takes in the new knowledge and skills.

Something akin to walkthroughs are used in very many forms of human endeavor since the process is a thought experiment that seeks to determine the likely outcome(s) of an affair based on starting conditions and the effects of decisions taken.
