In software engineering, a walkthrough or walk-through is a form of software peer review "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". [1]
The goal of the inspection is to identify defects. Commonly inspected work products include software requirements specifications and test plans. In an inspection, a work product is selected for review and a team is gathered for an inspection meeting to review the work product. A moderator is chosen to moderate the meeting.
The book, published in 1973, details the problems of software validation and testing. [2] Hetzel and Dave Gelperin co-found the Software Quality Engineering consultancy firm in 1986. In 1988 they classified the phases and goals of software testing into the following stages: [3] Until 1956 – Debugging Oriented – Until 1956 it was the ...
The most obvious value of software reviews (especially formal reviews) is that they can identify issues earlier and more cheaply than they would be identified by testing or by field use (the "defect detection process") [citation needed]. The cost to find and fix a defect by a well-conducted review may be one or two orders of magnitude less than ...
This might be a software design document or program source code, but use cases, business process definitions, test case specifications, and a variety of other technical documentation, may also be subject to technical review. Technical review differs from software walkthroughs in its specific focus on the technical quality of the product ...
That is to say, a peer review that identifies a requirements problem during the Requirements analysis activity is cheaper and easier to fix than during the Software architecture or Software testing activities. The National Software Quality Experiment, [2] evaluating the effectiveness of peer reviews, finds, "a favorable return on investment for ...
ISO/IEC/IEEE 29119 Software and systems engineering -- Software testing [1] is a series of five international standards for software testing.First developed in 2007 [2] and released in 2013, the standard "defines vocabulary, processes, documentation, techniques, and a process assessment model for testing that can be used within any software development lifecycle."
A cognitive walkthrough starts with a task analysis that specifies the sequence of steps or actions required by a user to accomplish a task, and the system responses to those actions. The designers and developers of the software then walk through the steps as a group, asking themselves a set of questions at each step.
