Documents should be distributed before the meeting. Meeting should not last longer than two hours. SQA specialist chairs the meeting because he(she) has the most to lose. Purpose of walkthrough is to detect the fault(s).
Two ways of conducting the walkthrough:
participant-driven, or
document-driven.
The second approach is likely to detect more faults and recommended
by IEEE standard for software reviews.
Discussion: Why the walkthrough should not be chaired by the
team manager?
